Question 1: What kind of fertilizer should be used to grow green storage corn? Nitrogen fertilizer is the main one.

Question 2: How to fertilize green storage corn? Green storage corn mainly focuses on biological yield, mainly nitrogen fertilizer. host. To ensure their stems and leaves are strong and increase yield. Apply fertilizer three times. The first time is to apply 10-12 kg of urea per mu at the 3-4 leaf stage of the seedlings, and apply it in the middle of the two rows when the soil is moist; the second time is to apply 60-70 kg of ammonium bicarbonate per mu deeply in mid-to-late May. For the third time, 20-25 kg of urea was applied in mid-June, between the two rows of corn. Pay attention to timely irrigation after fertilization to increase fertilizer efficiency.

Question 3: What kind of fertilizer should be used to grow silage corn? It is best to use corn soil testing and formula fertilization technology. 1. Characteristics of fertilizer requirements of corn 1. Characteristics of nutrient requirements of corn in different growth periods. Corn needs nutrients in each growth period. The proportions are different. From emergence to jointing, corn absorbs 2.5% nitrogen, 1.12% available phosphorus, and 3% available potassium; from jointing to flowering, it absorbs 51.15% nitrogen, 63.81% available phosphorus, and 97% available potassium;...

< p> Question 4: What kind of chemical fertilizer is used for growing silage corn? It is best to use organic fertilizer fermented by Nongshengle microbial organic fertilizer starter:

1) Microbial organic fertilizer has complete nutrients; chemical fertilizer has only One or several.

2) Microbial organic fertilizers can improve the soil; regular use of chemical fertilizers will cause soil compaction.

3) Microbial organic fertilizers can improve product quality; excessive application of chemical fertilizers leads to poor product quality. 4) Microbial organic fertilizers can improve the crop rhizosphere microbiota and improve the plant's resistance to diseases and insect pests; chemical fertilizers, on the other hand, make the crop microbiome single and prone to pests and diseases.

5) Microbial organic fertilizer can promote the utilization of chemical fertilizers and improve the utilization rate of chemical fertilizers; the use of chemical fertilizers alone can easily cause the fixation and loss of nutrients.

Question 5: What kind of fertilizer is best for growing silage corn? As long as it is organic fertilizer, it is more cost-effective to ferment organic fertilizer yourself!

Functions and effects

1. The decomposed organic fertilizer breeds a large number of functional bacteria and produces a variety of special metabolites, thereby promoting the growth and development of crops.

2. Improve crop disease resistance, drought resistance, and cold resistance, and improve fertilizer quality.

3. Achieve slow-release effects, improve soil aggregate structure, alleviate soil compaction, inhibit harmful bacteria, reduce the occurrence of pests and diseases, fertilize soil, and improve crop quality.

How to use

Dilute it ten times with bran powder before use. For fermented manure organic fertilizers, add 300-1000g per ton; for fermented other organic fertilizers, add 1000g per ton. The total moisture content is controlled at around 40%.

Question 6: What needs to be added to corn straw silage? The most important thing to add to corn straw silage is to add Lebeifon brand lactic acid bacteria silage agent. Its function is to inhibit the silage from molding by producing lactic acid bacteria. deterioration and prevent secondary fermentation. For other things, you can add some salt, corn flour, bran and other nutrients. The quality of the silage feed will be better. I hope it can help you!

Main points of cultivation

1. Selection of soil and fertilization: Fertile loam is suitable as the soil, and there are no other special requirements. This variety has tall plants and likes water and fertilizer. Fertilization should be combined with organic fertilizer and nitrogen, phosphorus and potassium. Generally, 350-450 kilograms of compound fertilizer is applied per hectare as base fertilizer. Adding organic fertilizer can adjust the soil and increase yield significantly. During the jointing stage, apply 500-600 kilograms of nitrogen fertilizer per hectare.

2. Timely sowing: According to the actual local climate conditions, when the temperature of the 5cm soil layer on the surface of the ground stabilizes at around 15°C, the appropriate soil moisture should be grasped and timely sowing can be carried out. The sowing method can be pond sowing, drill sowing, or single sowing. Grain sowing or mulching, seedling transplanting and other cultivation techniques are combined.

3. Appropriate density: Silage corn should be planted at a reasonable density. The specific planting density depends on local climate conditions, sowing time, soil fertility and fertilization level. It is generally recommended to plant about 4,500-5,500 plants per acre. (Plots with fertile soil and irrigated conditions should reduce the seeding rate, otherwise increase the seeding rate)

4. Other management: When the corn is in the three-leaf to four-leaf stage, single seedlings should be reserved. Combining the conditions of different plots, timely weeding can be carried out to prevent and control corn borer, Spodoptera exigua and other corn field pests.

Question 9: What is the best fertilizer for planting and storing green corn in salty land? 1. Corn straw silage storage technology Use the silage method to preserve the corn straw that remains green or partially green after the autumn harvest for a longer period of time. It preserves its nutrients well, becomes soft in texture and has a fragrance, which can increase the appetite of cattle and sheep and solve the shortage of forage in winter and spring. At the same time, making silage saves half the floor space than stacking the same amount of hay. It is also beneficial to prevent fire, rain, mildew and rot, and eliminate crop pests on the straw. The technical key to making silage is to provide necessary conditions for the reproduction of lactic acid bacteria: First, during the preparation process, the raw materials should be cut as short as possible and compacted tightly when loading into the cellar to eliminate as much air as possible in the cellar. Second, the water content in the raw materials is about 75% (that is, when the water can just be squeezed out by hand but cannot drip), it is most suitable for the reproduction of lactic acid bacteria. During silage, whether watering is needed should be determined based on the greenness of the corn stalks. Third, the raw materials must contain a certain amount of sugar. Generally, the sugar content of corn straw meets the requirements. There are many ways to silage corn straw. Here we only introduce the most basic general silage method to facilitate popularization and promotion in rural areas. 1. When digging a cellar, choose a place with solid soil, high and dry terrain, leeward to the sun, and difficult to be flooded by rainwater to build a silage cellar. The shape of the cellar is generally divided into round and rectangular. The cellar wall is straight and smooth, impermeable to water and air. The width of the cellar should generally be smaller than the depth. A better ratio is 1:1.5-2, which is conducive to compacting the raw materials by their own weight and reducing losses. The size of the cellar should be determined based on the amount of silage and the number of livestock. The diameter of a circular cellar is generally between 1.7-3 meters, the depth is preferably 3-4 meters, and the bottom should be in the shape of a pot. Large-scale livestock farms should adopt rectangular pits with a width between 1.7-3 meters and a depth of 2.3-3.3 meters. The length depends on the amount of silage. The corners of a rectangular pit should be rounded to facilitate the descent and compaction of raw materials. In order to reduce the loss of silage, a layer of plastic film should be spread at the bottom and around the pit. 2． To calculate the capacity of a silage cellar, one should first grasp the weight of the silage per unit volume (cubic meter) based on the moisture content of the raw material and the degree of chopping (for example, when corn stalks have low moisture content, the weight per cubic meter of finely chopped is 430-500 kg; thicker cut is 380-450 kg), and then multiplied by the volume of the cellar (a circular cellar is 3.14x radius 2x cellar depth; a rectangular cellar is cellar length x cellar width x cellar depth, unit (all in meters), that is, the weight of the silage in the pit (kg) is obtained. 3. It is best to cut and store silage raw materials on the same day. Before loading the cellar, check whether the bottom and walls of the cellar are paved with "bottoms" and whether reed mats are laid on the sides of the cellar (to prevent raw materials from being contaminated and soil from entering the cellar), and then start the mowing machine (the chopping length should not exceed 3.3 cm). Chopping and loading at the same time, try to avoid the chopped raw materials being exposed to the sun for too long outside the cellar. The raw materials loaded into the cellar should be spread out at any time. If the ingredients are too dry, sprinkle some water evenly. It needs to be compacted every 30 cm or so. Special attention should be paid to compaction around the cellar. It is better to tamp it with a stone pestle or rely on a tractor. The cellar is filled layer by layer, and the cellar is sealed when it is 0.5-1 meters above the ground and forms a dome shape.

When sealing the cellar, first cover it with a layer of plastic film, add a layer of soft hay, tamp it with soil, and pat the surface smooth. After sealing, a drainage ditch should be dug 1 meter away from the cellar entrance, and the top of the cellar should be checked frequently for signs of subsidence. If subsidence is found, it should be repaired to prevent air and rain from entering.

Question 10: How to store silage? I use corn stalks. What method is used to make silage? The process of making silage: harvest → chop → add additives → bagging and storage.

Harvesting raw materials must be done at the right time to obtain the most nutrients in feed production. If harvested too early, the raw materials will contain more water and less digestible nutrients; if harvested too late, the fiber content will increase, the palatability will be poor, and the digestibility will decrease.

Harvesting of corn stover: Whole plant corn stover silage is generally harvested during the milk-ripening stage of corn seeds. After harvesting the corn stalks, the corn stalks are usually picked immediately when the corn stalks are 70% mature and the leaves have not yet withered or when 1-2 leaves at the base of the corn stems have begun to wither and yellow. On the day of picking the corn stalks, the corn stalks will be picked the next day at the latest. Corn stalks are harvested to make silage.

Harvesting of forage: Leguminous forage is generally cut for silage from budding to the beginning of flowering; grass forage is generally cut for silage from booting to just heading; sweet potato vines and potato stems and leaves are generally cut during potato harvesting. Harvest silage 1-2 days before or before frost. After harvesting, young pasture or weeds can be siled in the sun for 3-4 hours (in the south) or 1-2 hours (in the north), or mixed with corn stalks.

Chop In order to facilitate bagging and storage, the raw materials must be chopped. Corn straw, pine, vanilla straw or chicory straw must be chopped to about 1-2M long before silage, and can be compacted during silage. Forage grass and vines are soft and easy to compact. Cutting them into silage lengths of about 3-5M will produce better results.

Add additives. Add additives immediately after chopping the raw materials in order to allow the raw materials to ferment quickly. 2-3% sugar, formic acid (3-4K formic acid with a content of 85% per ton of silage raw material), amylase and cellulase, urea, ammonium sulfate, ammonium chloride and other ammonium compounds can be added.

Filling and storage can usually use methods such as plastic bags and cellars. Before loading the cellar, lay 10 to 15 cm thick straw on the bottom to absorb the juice. The four walls of the cellar should be covered with plastic film to prevent water leakage and be breathable. It should be installed firmly. It can be rolled with a bulldozer and tamped manually until it is about 60 centimeters above the edge of the cellar, and then it can be capped. When capping, first lay a layer of short-cut straw, add a layer of plastic film, and then cover it with soil and pat it firmly. Drainage ditches should be dug 1 meter away from the cellar to prevent rainwater from flowing in. When there are cracks in the cellar roof, cover them with soil and compact them in time to prevent air and water leakage. The bagging method requires opening the bag mouth, putting each bag of silage raw materials into a special plastic bag, pressing it firmly with your hands and feet until the filling is about 30M away from the bag mouth, then pumping out air, sealing, and tightening the bag mouth.

As long as the successfully fermented silage does not leak air and is not opened, it can be stored for 10 to 20 years.
