The crop can only grow well if it is under balanced nutrition, resulting in high yields. Fertilizer applied to the soil, in addition to the balance of various elements, but also in a certain degree of soil pH and soil temperature and humidity conditions can be absorbed by the crop. Scientific fertilization can not only meet the nutrients needed by crops, but also regulate the pH and temperature and humidity of the soil. To achieve scientific fertilization, the following points must be achieved: 1. The application of a large number of element fertilizers and trace element fertilizers. According to different crop types to determine the application of nitrogen, phosphorus, potassium nutrient content, and the amount of trace elements required by different crops and how much to determine the amount of fertilizer, fertilization time and method. 2. Organic fertilizer and inorganic fertilizer with the application. The combination of organic fertilizer and inorganic fertilizer can fully supply nutrients needed by crops, reduce nutrient fixation, further increase fertilizer efficiency, conserve nutrients, reduce loss, improve crop nutrient absorption, effectively regulate soil pH, improve soil structure, increase soil nutrients, Improve soil vitality. 3. Use of farmyard manure and inorganic fertilizer There are four types of farmland fertilizers and inorganic fertilizers that are used together with science: (1) Human excrement and calcium superphosphate Add 5 kg of superphosphate per 100 kg of human waste. Stir and store it for 3-10 days. This will make ammonium bicarbonate, which is highly volatile in human waste and urine, convert to stable ammonium phosphate, thus increasing human dung. Phosphorus in the urine, phosphorus nitrogen, fertilizer efficiency increases. (2) Plant ash and calcium superphosphate With plant ash 6 kg watered 30 kg soaked, plus 2 kg of superphosphate, 6 hours after adding 100 kilograms of water and mix well, after standing to take a clear liquid spray, you can get the same fertilizer effect as potassium dihydrogen phosphate. (3) Stacking fertilizer and ammonium bicarbonate The weeds, plant stalks, and leaves were smashed into sections, 0.5%-1% of ammonium bicarbonate was added, and human feces and urine were piled up and tanned. Then, the mud was covered and sealed, and when fully cooked, it became a highly efficient biopotash fertilizer. (4) Application of manure and superphosphate Adding 20% ​​of superphosphate to the silos of the livestock bar and mixing it for 20 days will not only prevent the loss of nitrogen nutrient in the manure, but also accelerate the maturity of the manure and increase the content of available phosphorus. In addition, there is a general principle of fertilization: that is, no matter what fertilizer is applied, we must look at the sky, see the land, and watch the crop grow. According to the local cultivating department's soil testing formulation formula, scientific and rational fertilizer application.
