Formula fertilization, also called soil fertilization and balanced fertilization, is a major reform of fertilization technology. It is the comprehensive use of modern agricultural science and technology achievements, according to crop fertilizer requirements, soil fertility performance and fertilizer effects, under the conditions of organic fertilizers, the appropriate amount and proportion of nitrogen, phosphorus, potassium and medium and trace elements are proposed before birth and corresponding The scientific fertilization method of fertilization technology.
In the 1980s, with the development of the fertilizer industry and the improvement of agricultural production levels, the application rate of chemical fertilizers increased rapidly. In 1978, the total amount of physical fertilizer in the province was 4.102 million tons. In 1980, it increased to 6.967 million tons. In 1982, it reached 7.791 million tons.
The increase in the amount of chemical fertilizer has put forward higher requirements for fertilization technology, and it is necessary to make scientific use, reasonable ratio, and proper application. In 1982, the application ratio of nitrogen, phosphorus and potassium was 1:0.2:0.02, which was far from the soil nutrient content and crop demand, and was far from being suitable for production.
In order to completely solve the problem of long-term large-scale single fertilization, imbalance of proportion and fertilization according to experience, and improve the utilization rate of fertilizer and economic benefits of fertilization, starting in 1983, first in Jiaxiang, Cangshan, Huimin, Jimo, Lishui, Yucheng and other counties Pilot work on formula fertilization technology in low- and medium-yield fields was carried out. In the autumn, a total of 820,000 mu of demonstration area was arranged. In 1984, the average yield per mu of wheat in the demonstration area reached 207.4 kg, which was 72.9 kg higher than the average yield of 134.5 kg in the first three years of the demonstration area. The yield increased by 54.2%, and the yield increase effect was extremely significant. In 1984, a demonstration demonstration of corn formula fertilization was arranged. Subsequently, the trial fertilization test, demonstration and promotion of cotton, peanuts, soybeans, tobacco and famous special crops have also started. After 1986, formula fertilization technology was listed as one of the top ten technologies for agricultural planting in our province.
