The first is soil testing and formula fertilization. That is to say, the content of the main elements in the soil is first measured, and then scientific and rational fertilization is carried out according to the nutrients required for the crops, and how much is needed to avoid waste. Compared with conventional fertilization, soil testing and formula fertilization can increase the yield per unit area of ​​rice, wheat, corn and other major food crops by 6% to 10%, and increase the efficiency of crops by more than 30 yuan. The effect of increasing economic crops is more obvious. More than 80 yuan. According to the statistics of the agricultural sector, the soil testing and formula fertilization demonstration area generally reduces the unreasonable fertilization amount per mus by 1 to 2 kg (pure, the same below). As of 2012, through the implementation of soil testing and formula fertilization, the country has reduced irrational fertilization by more than 8.5 million tons, reducing the loss of nitrogen and phosphorus by 6% to 30%, achieving double savings in production costs and resource consumption.
The second is to promote slow release fertilizer. The so-called slow-release fertilizer refers to a new type of fertilizer that has a slow release rate of fertilizer nutrients and a long release period, which can meet the growth needs of crops throughout the growing season of crops. After years of demonstration and promotion, the effect of slow-release fertilizer on fertilizer saving, yield increase and efficiency improvement is very significant. Compared with the fertilizer commonly used by farmers, the average yield of slow-release fertilizers increased by 10%, the highest reached 40%, and the economic benefits were also improved. The average income per mu increased by 120 yuan, and the highest reached 240 yuan.
The third is to increase the area of ​​water soluble fertilizer application. Water soluble fertilizer is a multi-element compound fertilizer that is completely soluble in water. Compared with traditional superphosphate, ammonium phosphate, granulated compound fertilizer and other varieties, water-soluble fertilizer is more easily absorbed by crops, achieving the same application of water and fertilizer, integrating water with fertilizer, integrating water and fertilizer, achieving the effect of water saving and fertilizer saving. . Its effective absorption rate is more than 1 times higher than that of ordinary fertilizers, reaching 80% to 90%. Norwegian well-known fertilizer expert Dr. Moran said that China's irrigated land area is the second largest in the world, and the amount of fertilizer used is the highest in the world. The task of improving water and fertilizer utilization is very arduous. The US fertilizer utilization rate has risen dramatically in the 1960s, due to the large-scale promotion of water-soluble fertilizers.
