Wheat is a common field crop in the north. The ratio of nitrogen, phosphorus and potassium in the whole growth period is about 1.6:1:1, and the three nutrient requirements are relatively average. For example, the yield of 500-600 kg per mu is recommended.
Base fertilizer: Applying wheat base fertilizer is an important measure to improve soil fertility in wheat fields. The amount of base fertilizer should be based on production requirements, fertilizer type, nature, soil and climatic conditions. The base fertilizer should account for 60%~70% of the total fertilization. Generally, a bag of wheat special compound fertilizer (50 kg) with a content of 25-15-5 on the right track is applied .
Top dressing: If the base fertilizer is insufficient or the crop is not growing well, it is necessary to topdress. Wheat should look at seedlings and topdressing. If the seedlings are not prosperous, the number of groups per acre is less than 600,000. It should be topdressed early; in early March, 20 kg of high-nitrogen compound fertilizer can be applied per acre; The growth is strong, the number of groups is more than 800,000. It should be lately topdressed and avoid ineffective tillers. In late March, 10 kg of normal nitrogen fertilizer or 10 kg of normal urea fertilizer can be applied per mu. If the population is between 600,000 and 800,000, It is best to topdress in mid-March, and the acre is 15kg high-nitrogen fertilizer or 15kg of normal urea .
Foliar topdressing: When wheat is fertilized from the booting stage to the middle stage of grain filling, it can prolong the functional period of the leaf and maintain the root activity of the wheat, prevent premature aging, prevent dry hot air, promote grain filling, increase grain weight and improve grain quality. Important measures. Foliar spray fertilizer can generally be used with about 2% urea solution (50 kg per 1 mu of urea plus water), or 200 g of potassium dihydrogen phosphate per acre for 50 kg of water, or combined with pest control. Top dressing, but should be used with the use.
Suggestions on the Rational Fertilization of Wheat by the Right Compound Fertilizer
Wheat is an important food crop in China, and its planting area and total output are second only to rice. Wheat cultivation ranges from Hainan Island in the south to Heilongjiang in the north, Xinjiang in the west, and plain mountains in the coastal provinces. China grows both winter wheat and spring wheat. For wheat cultivation, it is very important to fertilize high yields. There is a saying that is called a crop, and it depends on the fat, so how to apply compound fertilizer in wheat cultivation is the top priority of high yield.
