In the spring of this year, experts in agriculture, soil and fertilizer in Jilin and Heilongjiang proposed six scientific fertilization techniques and fertilizers worthy of promotion, such as soil testing and balanced fertilization, according to the current situation of agriculture and rural production in China, especially in the northeast region.
Promote soil testing and balanced fertilization technology
Soil-measured balanced fertilization is a major reform in China's fertilization technology. It is a comprehensive application of modern agricultural scientific and technological achievements and scientific and technological means. It first tests the soil to understand the soil fertility performance, and then comprehensively adjusts the crop fertilizer requirements. Under the organic fertilizer-based conditions. The appropriate dosage and proportion of nitrogen, phosphorus, potassium fertilizer and micro-fertilizer are proposed, and the fertilizer is directly applied to the fertilization technology of crops.
Increase the amount of organic fertilizer application, do a good job in building land, and maintain balance of soil power
The vast rural areas should actively organize manpower and material resources, carry out the accumulation of organic fertilizers, and do a good job in the construction of “three facilities†where “people have toilets, livestock have circles, and households have accumulated fertilizer pitsâ€. At the same time, farmers should be mobilized to make use of everything. Organic fertilizer resources, try to collect them, use them to make use of organic fertilizers to ensure the input of organic fertilizers per mu, and ensure the application of organic fertilizers of more than 1500 kilograms per mu, so as to achieve the goal of combining land and land and increasing yield.
Promote the application of special fertilizers for crop series
The special compound fertilizer for crop series is a physicochemical product of formula fertilization technology, which contains various nutrients such as nitrogen, phosphorus and potassium required for the growth of crops. It solves the problem that the rural areas are widely difficult to be used for a long time. Compared with simple fertilizer or customary fertilization, the yield can be increased by 15%.
Promote efficient and pollution-free environmentally friendly fertilizer
Bio-organic compound fertilizer is an agricultural technology project promoted by the Ministry of Science and Technology and the Ministry of Agriculture in the country. The result of this technology is the first in China and is in the leading position in the world. It is composed of organic fertilizer, inorganic fertilizer, bacterial fertilizer and synergist. The "four in one" fertilizer. The application of potash fertilizer to potassium fertilizer on potassium-deficient soil can generally receive the effect of increasing yield. In addition to organic fertilizer and dryland crop straw returning can supplement soil potassium, the application of chemical potassium fertilizer is the most direct and effective way to supplement soil potassium and supply potassium nutrition to crops.
Promote boron application in boron crops, and zinc in rice, wheat and corn, and molybdenum fertilizer in wheat and peanuts.
The application of boron in rapeseed, cotton, fruit trees, etc. is generally based on 0.5-1.0 kg per acre. It can also be sprayed on the foliar surface, 100-200 g per acre, 40-50 kg on water; zinc in rice and wheat maize. Mainly used as base fertilizer application, generally 1-1.5 kg of zinc per acre; molybdenum fertilizer seed dressing is generally about 12 grams of molybdenum fertilizer for one mu of seed.
