when is the spring ploughing in p>22?
China has a vast territory and abundant resources, and the time of spring ploughing varies from place to place.
the time of spring ploughing in the south is earlier, and it is postponed in turn to the north. The farther north, the later the spring ploughing season is.
Generally speaking, the temperature in the south rises rapidly. Spring ploughing begins in late February and early rice is sown in March every year. The general time of spring ploughing in northern China should be from March to April, and the specific sowing time is different because of the temperature, moisture and other factors in the region.
in terms of solar terms, most parts of the country have entered the busy season of spring ploughing when they are startled. The season really waits for no one, and every moment is worth a thousand dollars.
This year's surprise occurred at 1: 56 on March 5th in the solar calendar, which means that most parts of China have entered the busy season of spring ploughing since March 5th in the solar calendar.
what should farmers pay attention to when preparing fertilizer for spring ploughing?
① It should be based on organic fertilizer, and nitrogen, phosphorus and potassium fertilizer should be applied together
The specific fertilizer preparation varies from crop to crop. For field crops such as corn, rice, soybean, cotton and spring wheat, it is recommended to apply organic fertilizer, with all organic fertilizers or most phosphorus, potassium fertilizer and nitrogen fertilizer not exceeding half of the total amount as base fertilizer, and the rest as topdressing or seed fertilizer; For fruit trees and vegetables, it is necessary to apply organic fertilizer, part of nitrogen, phosphorus and potassium fertilizers as base fertilizer, and the rest as topdressing, and more attention should be paid to the supplement of medium and trace elements.
However, it should be noted that farmyard manure, such as human and animal manure and urine, should be composting before application, and cannot be mixed with alkaline fertilizers such as calcium magnesium phosphate fertilizer, plant ash and lime.
Because the main component of human and animal manure is nitrogen, if it is mixed with strong alkaline fertilizer, it will be neutralized and ineffective.
② Make a fertilizer preparation plan and avoid impulsive consumption
Our farmers should make a fertilizer preparation plan according to the actual needs of farming, and don't be influenced by the promotion and discount activities of merchants. Note that some shops have sales traps such as false price tag, fuzzy price tag, fictitious original price, false discount, fuzzy gift sale, concealing price additional conditions, and don't covet cheap impulsive consumption.
③ Buy products from regular manufacturers
Pay attention to the packaging and labeling of agricultural commodities such as fertilizers, pesticides and seeds, including product name, specifications, active ingredient content, trademark, factory name and address, production date, shelf life, certificate of conformity, quality and safety signs and other information, so as to avoid buying "three no products" and expired commodities.
④ Leave the invoice
When selling agricultural materials, you must ask for the sales invoice, on the one hand, it can avoid tax evasion by merchants, on the other hand, it can be used as a basis for litigation in case of disputes in the future.
⑤ Proper storage
A large amount of fertilizer should be stored in a ventilated and waterproof room, placed on things such as plastic sheets to isolate moisture on the ground, and covered with canvas or plastic sheets after stacking, so as to prevent fertilizer nutrient loss, reduce fertilizer caking and fertilizer volatilization poisoning as much as possible.
Special attention should be paid not to pile ammonium nitrogen fertilizer with seeds and microbial fertilizers, so as not to harm seeds and active microorganisms by the volatilized ammonia gas.
