The so-called "southern rice and northern wheat".
Rice planting technology
This crop likes high temperature, high humidity and short sunshine, and has low requirements for soil.
South China is the main producing area, and it is planted in all northern provinces.
1, seed treatment
Seed treatment is a prerequisite for planting technology. Generally, before planting, the selected seeds are cleaned, disinfected with potassium permanganate solution, and then put into gauze bags to accelerate germination, and the temperature is kept at about 30℃ to germinate quickly.
2. Soil preparation treatment
In order to ensure the fertility of the cultivation substrate, it is generally necessary to combine intertillage weeding treatment during soil preparation, then add a proper amount of fertilizers such as organic fertilizer, calcium superphosphate and potassium sulfate into the soil, mix them evenly, and then add a small amount of Pinus elliottii for sterilization.
3, transplanting treatment
Transplant the germinated seedlings into the soil, don't cultivate them too closely, keep the plant spacing at about 10 cm, hold the roots by hand, and insert them into the soil, preferably not too shallow, and keep the roots completely covered with soil, or use a seedling separator, which is more efficient.
4. Post-planting treatment
If missing seedlings are found after planting, they should be replenished in time to ensure the original planting density. Frequent irrigation is needed during the growing period, and water can be increased at the seedling stage. Generally, only one third of the water is submerged, and then ammonium sulfate fertilizer can be added appropriately according to the growth situation.
5. Weeding treatment
It is best to weed frequently after planting. Herbicide, mainly oxadiazon, can be applied within one week after planting. When growing well, benzothiazole herbicides can be added to the fertilizer, mixed and sprayed to prevent weeds from affecting the normal growth of plants.
