The main method to improve fertilizer efficiency
1. Organic fertilizer piled up and cooked as base fertilizer In late July, press 4000 kilograms of human feces at Xiangyang, add 100 kg of calcium, magnesium, phosphorus, and 400 kg of crushed wheat straw. After mixing, piling up into a cocoon shape, cover it with shabby plastic film or use a straw to cover the soil. Days, high-quality organic fertilizer is used as a base fertilizer in greenhouses. 2, superphosphate concentrated as base fertilizer In the transplanting line open 8 cm deep ditch, after the removal of phosphate fertilizer cover 4-5 cm, and then transplant the crop in the shallow ditch, shorten the distance between the phosphorus fertilizer and the crop root to make up for the weakness of the phosphorus mobility. 3, urea early application, deep application and external application According to the demand of fertilizer and water in the development stage of crops, early application and deep application will increase the utilization rate by 28% compared with shallow application. Shed temperature is 7 days in advance at 15-20°C, shelf temperature is 5 days in advance at 20-25°C, 8-10 cm ditch is opened at topdressing, and soil is tightly covered after withdrawal. Holes can be applied to crops with large row spacing. Deeply. According to greenhouse temperature watering every 5-7 days, it has enough time in the soil to fully ammonia, in order to facilitate the absorption and utilization of crops. During the growing period of the crop, the foliar may be sprayed with 0.3% urea solution once every 7 days, with 100 kg per mu, for 2 to 3 consecutive times. 4, ammonium bicarbonate deep application Ammonium bicarbonate is an ideal quick-acting fertilizer for winter greenhouse vegetable production. Because it evaporates at a low temperature of 20°C, it can dissociate into ammonium ions and be absorbed by the soil after it is applied to the soil, and then slowly release it for the root absorption of the crop, even at 5 Under the soil temperature condition of °C, it can also be transformed and absorbed by crops. When composting, it should be 10 to 10 cm deep from the roots of the crop, and the ditch should be covered with soil after spreading. The utilization rate can be increased by 10 to 30%, and the yield can be increased by 10% compared to the shallow application, and the yield can be increased by 7.8% compared with the water application. Oat Powder is produced by the specific enzymatic hydrolysis and spray drying technology, so it is called Hydrolyzed oat powder or Enzymolysis Oat Powder. It has a pleasant oat fragrance with creamy mouthfeel and smooth texture. It retains all the soluble nutrients of oats, such as high-quality plant protein, fat, soluble dietary fiber(3-glucan>3%). It is high-viscosity and slightly sweet, easy to digest and absorb. It is stable and good resistance to acid and heat treatment after dissolution in water.
