At the time of the "three summers," the reporter learned yesterday from the Shaanxi Province Soil and Fertilizers Workstation that the station creatively proposed a "large formula, small adjustment" formula fertilization promotion model, for the first time summer corn, rice and other summer sowing crops fertilizer formula. According to preliminary calculations by experts, according to this model, the summer corn and rice in Shaanxi Province will be calculated at 10 million mu, which can increase grain production by 160 million kilograms and increase economic benefits by 300 million yuan.

The “large formula and small adjustment” formula fertilization model is a way for formula fertilizer manufacturers to supply summer crop crop fertilizer in accordance with the “large formula” standardization and scale production, which can effectively promote the application of soil testing and fertilization results. According to the results of soil testing, selective “pilling by prescription” is sufficient as long as the fertilizer is purchased into the farmland, and at the same time, the problem of lack of formula fertilizer can be effectively solved.

According to Li Sixun, director of the Soil and Fertilizer Station in Shaanxi Province, this spring, based on the characteristics of Shaanxi's main crops, nearly 40 types of summer corn and rice were collected based on soil testing and fertilizer efficiency tests. The high-yield type of fertile land and the economic type suitable for medium and low-yield fields lead the formula fertilizer production enterprises to produce formula fertilizers for supplying summer corn and rice in accordance with the “large formula” according to the results of soil testing, so that farmers can scientifically apply fertilizers easily. The "large formula" contains all the phosphorus and potassium fertilizers and part of the nitrogen fertilizer. The application of the remaining nitrogen fertilizer belongs to the "small adjustment", that is, the technicians instruct the people to follow up the nitrogen fertilizer in the period of maximum nutrient efficiency of the crop according to the field conditions of the crops to ensure food production. High yield and high efficiency.

According to the summer sowing crop fertilization formula provided by the Shaanxi Soil and Fertilizer Workstation, the high-yielding formula of summer corn has a total nutrient content of 40% (including nitrogen 12%, phosphorus 18%, and potassium 10%), and applies 40 kg of fertilizer per acre as a base fertilizer, and topdressing Urea 20-24 kg, target mu yield 500-650 kg; economic formula total nutrient content 30% (including nitrogen 10%, phosphorus 12%, potassium 8%), 40 kg per acre as a base fertilizer, and topdressing urea 13 ~17 kg, 500 kg of target mu yield. The high-yield formula rice has a total nutrient content of 45% (including 18% nitrogen, 12% phosphorus, and 15% potassium), 50 kg of fertilizer per acre as base fertilizer, and top dressing of 7 to 10 kg of urea, with a target yield of 600-700 kg. The economical formulation has a total nutrient content of 35% (16% of nitrogen, 9% of phosphorus, and 10% of potassium). Each acre is used as a base fertilizer to fertilize 50 kilograms, topdressing urea 5 to 9 kilograms, and a target mu yield of 600 kilograms.

It is understood that after the successful summerization of large-scale fertilizer application in crop sowing, Shaanxi will publish autumn crop fertilization formula.
