Potato Nutrition
       Potatoes need a lot of fertilizer, how to fertilize potatoes?
         
       Potatoes belong to tuber crops. The main growth process is the accumulation of starch, protein, sugar and other substances. Therefore, rational fertilization and the ratio of elements such as nitrogen, phosphorus and potassium are the key to increasing yield and quality of potatoes. So how should the fertilizer be applied during the potato planting process, especially how to apply phosphate fertilizer?
       
       The fertilizer requirement of potatoes.
       
       If you want high-yield and high-quality potato, you must first understand the fertilizer requirement of the potato, and apply it as needed to increase the utilization rate of fertilizer and achieve the goal of high yield and quality. The fertilizer requirement of potato seedlings is generally not too large, and the amount of fertilizer required to reach the peak period begins at the beginning of the tuber differentiation stage. Potato is a high-starch tuber plant that has the highest demand for potash, followed by nitrogen fertilizer, which has the least amount of phosphate fertilizer.
       
       Potassium fertilizer can promote the accumulation of starch and vitamins in potato tubers, and the lack of potassium fertilizer can easily cause dwarfing and wilting of plants, and even cause tuber blackening to affect consumption. Therefore, potatoes have a greater demand for potash. At the same time, trace elements such as boron and copper are also essential. Potato fertilization requires heavy base fertilizer and less topdressing.
       
       Because the tuber of potato is an important part of organic matter accumulation, it is more suitable for sandy loam soil, which is conducive to tuber enlargement. At the same time, farmyard manure is beneficial to improve soil permeability and promote potato root and tuber growth, and excessive application of chemical fertilizer will result in Soil compaction is not conducive to tuber swelling, so the base fertilizer should be based on farmyard manure, combined with fertilizer application.
       
       Potato fertilization points and application characteristics of phosphate fertilizer.
       
       How to apply phosphate fertilizer? Phosphate fertilizer can increase potato starch content and yield, and can grow seedlings. Insufficient application, it is easy to cause the potato tubers to be hollow, hardened, not easy to be boiled, etc., affecting the quality of the tubers and even reducing production. Generally speaking, the soil in the north is generally deficient in phosphorus. Therefore, it is necessary to pay attention to the application of phosphate fertilizer, but it should not be excessive. Generally, when the base fertilizer is applied, organic fertilizer is added to apply phosphorus pentoxide.
       The specific application amount should be determined according to the amount of potato produced. Generally, the production of 1000 kg of potato requires the application of phosphorus pentoxide 1.8 to 2.2 kg. In addition, according to the condition of the potato plant, 50 kg of 0.3-0.5% potassium dihydrogen phosphate solution was sprayed on the foliar surface as a root dressing.
       
       The main points of fertilization of potatoes.
       
       The amount of base fertilizer applied accounts for 2/3 of the amount of fertilizer applied during the whole growth period of the potato. Generally, the farmyard manure is mainly applied with about 2000 kg per mu, and the high-nitrogen and high-potassium compound fertilizer is 40-60 kg. At the late stage, it is necessary to pay attention to the demand for nitrogen fertilizer in the potato seedling stage. Generally, the urea is applied 5~8 kg, which can be applied with water. After the flowering, the potato is generally no longer applied with nitrogen fertilizer to avoid the plant growth. In the later stage, if the plant has symptoms such as premature aging and yellowing, it can be sprayed 2 to 3 times by foliar application, and the total amount does not exceed 1 kg.
       
       It should be noted that the potato is a potassium-prefer crop, and in the usual fertilization process, people generally pay attention to the application of nitrogen fertilizer and phosphate fertilizer, resulting in too little potassium fertilizer application, which affects potato yield. In addition, when applying potassium fertilizer to potato, it is best to choose potassium sulfate or potassium dihydrogen phosphate to avoid the application of chlorine-containing fertilizer to affect the quality of the potato. At the time of fertilization, attention should be paid to balanced fertilization. For example, boron deficiency can cause tuber cracking. Copper can promote plant respiration and photosynthesis. Appropriate fertilization can increase potato yield and improve plant drought resistance.
