How to fertilize summer corn to increase production? Corn is one of the main food crops in the north. The high and low yield of corn directly affects the income of farmers' economics. Therefore, fertilization of corn can not be ignored. It is said that crops and flowers are all dependent on fertilizers. How to fertilize corn, buy fertilizer nets. I have summarized some of the methods commonly used on the current network. Reasonable fertilization of summer maize should consider the corn fertilizer requirement, target yield, soil properties, climatic conditions, fertilizer properties and agricultural technical measures. Summer maize is not tightly applied due to the timing of sowing, but attention must be paid to the supply of phosphorus, because the nutrient critical period of corn to phosphorus is about 7 days after emergence. The critical period of nitrogen nutrition is later than that of phosphorus, which is in the stage of differentiation of vegetative growth to reproductive growth. The maximum nitrogen efficiency of maize is in the early stage of the large trumpet period. In this period, the growth is rapid and the growth is large. The nitrogen fertilizer is applied in this period, accounting for 2/3 of the total nitrogen. The absorption of potassium by summer maize has basically reached the highest amount when heading and flowering, so potassium fertilizer should be applied early. In the corn seedling stage, the plant body is small and requires little fertilizer. However, if the nutrient is insufficient, the seedlings will be relatively weak, the leaves will be light, and the root growth will be hindered, which will affect the growth in the middle and late stages. Therefore, after the seedlings are planted, the seedling fertilizer should be applied lightly in time to promote the strong seedlings. Miao Fei is better with decomposed human and animal excrement and quick-acting nitrogen fertilizer. However, avoid applying too much to prevent seedlings from growing. The fertilizer applied at the jointing stage is called strong stalk fertilizer, and the effect is strong stalk, and it also has the effect of promoting the differentiation of the male and male ears. Especially for the mid-early maturing and early-maturing varieties of summer maize, the application of strong stalk fertilizer has a significant effect on increasing yield. There is generally no lack of micro-fertilizer in the soil, but in the soil with excessive pH or the area with less organic fertilizer and nitrogen fertilizer, it is prone to deficiency syndrome. Appropriate application of micro-fertilizer can increase the yield. Zinc fertilizer: The amount of zinc fertilizer varies depending on the method of application. Reasonable fertilization refers to the rational supply and regulation of various nutrients necessary for crops to meet the needs of crop growth and development, so as to achieve the purpose of increasing yield and improving the quality of agricultural products, reducing fertilizer waste and preventing environmental pollution. There are many types of fertilizers, their properties are different, and the application methods are not the same. Ammonia nitrogen fertilizer is easily soluble in water, crops can be directly absorbed and utilized, and fertilizer efficiency is fast, but it is easy to decompose and volatilize when exposed to alkali, so it should be applied deeply and immediately covered. After the urea is applied to the soil, it can be absorbed by the corn through the action of microorganisms and hydrolysis. Therefore, the urea should be applied in advance as a top dressing, and the strip application, the hole application and the ditch application should be adopted to avoid the application. Weakly acidic phosphate fertilizer should be applied to acidic soil. Poor application on calcareous soils. Chemically neutral, physiologically acidic fertilizers such as potassium sulfate and potassium chloride are most suitable for application on neutral or calcareous soils. The application of base fertilizer in summer maize can be carried out in combination with cultivation or shallow tillage. However, in the two-crop area in the year, it is very important to plant the summer corn when it is harvested. It is often too late to apply organic fertilizer as the base fertilizer. Generally, the effect of organic fertilizer and phosphate fertilizer in winter wheat is utilized. Or use winter wheat roots and straw to return to the field to make up for the shortage of summer corn base fertilizer. In addition to fertilization, attention should be paid to drought prevention during the critical period of corn growth and development. Drought during the large trumpet period often causes difficulty in tasseling, resulting in poor pollination; dry long silking leads to poor pollination and fertilization, reducing the number of grains per ear, reducing grain weight, and reducing yield most severely.
