Relying on scientific fertilization to reduce autumn broadcast investment

At the end of September and early October, wheat in Shandong and other places will begin to be planted, and another peak season for fertilizer is coming. Judging from the current situation of the fertilizer market, this year's autumn season fertilizer still continues to have high prices. Farmers who have been accompanied by high fertilizer prices for one year can only change their own fertilizer habits and strive to reduce investment and output. 
At present, the most direct way for farmers to cope with high fertilizer prices is to reduce the amount. Some farmers think that now the base fertilizer is less applied, and when the wheat returns to green next year, it may be that the price of fertilizer will drop, and then increase the amount of topdressing according to the price. Other farmers have begun to look for alternative products: one is to replace compound fertilizer with single element fertilizer, such as superphosphate and ammonium bicarbonate; the other is to replace fertilizer with organic fertilizer, which has been around for nearly a year. The endless development of various concepts of organic fertilizer is a proof. Organic fertilizers have become popular. First, they rely on price. Second, they rely on "green" and "environmental protection" to attach to the "halo" of organic fertilizer. Compared with the same 50 kg compound fertilizer, the organic-inorganic compound fertilizer is generally 70 yuan cheaper (including 20% ​​nitrogen, phosphorus and potassium), and the simple organic fertilizer can cost hundreds of yuan per bag. With the advantage of price, this year's organic fertilizer is very prosperous, and farmers are gradually increasing the amount of organic fertilizer used in hesitation. 
It is unavoidable for farmers to reduce the amount of chemical fertilizer application. As the saying goes, "A crop is a flower, it depends on the fat to be the master." It is unrealistic to think about not using fertilizer and high yield. To maximize the yield of crops, the most fundamental one is scientific fertilizer, especially It is formulated according to the soil nutrient content, and the principle of supplementing the soil is used to obtain the maximum harvest with the least amount of fertilizer. According to relevant experts, the average amount of fertilizer used is not more than 15 kg, plus some organic fertilizers and medium and trace element fertilizers, which can play a good fertilizer effect. However, most of the farmers are blindly fertilizing, or they are over-fertilized, resulting in good performance in the seedling stage. The effect is remarkable, but in the later period, it is often “not motivated”, the wheat is prone to lodging and other symptoms, and the yield is not high; or it is to reduce the input. Less or no use of fertilizers, resulting in crops "not enough", the output is significantly reduced. Facing the situation that fertilizer prices continue to be high and autumn is about to come, I hope relevant departments can increase publicity and let farmers know more about fertilizer. The qualified agricultural departments should implement the formula fertilization project to the grassroots for farmers. Scientific fertilization "out of the square" is not floating on the surface of "making a show"; as a fertilizer production enterprise, in the "high fat price era" should do a good job of agrochemical services, guide farmers to precise fertilization, scientific fertilization, in the use of fertilizer The value of this is more conducive to the long-term development of the enterprise; and farmers who are users of fertilizers should not be shut out because of the high price of fertilizers. They should understand the knowledge of formula fertilization, truly measure soil fertilization, and at the same time apply organic fertilizer. It is also necessary to choose the one that suits you, not just the price, not the actual effect, so that it will truly achieve the goal of less investment and more output, and better promote the development of agricultural science.
