1. Weather reasons

Weather reasons will lead to the appearance of bald tips of corn. I believe it should be the first thing that most farmers think of. The reasons for natural phenomena are mainly divided into two. There are two types, one is rainy and the other is continuous high temperature. If the corn field continues to have high temperatures and little water, the growth of the corn ears will be affected until the end of the impact period. The other is that when the corn is in bloom and pollinated, it encounters continuous rainfall, which will also cause the corn to become bald. It is difficult to control this kind of thing in the open field. In the case of greenhouse, certain methods can be adopted. Actual considerations will be made on a case-by-case basis. 2. Planting too densely

Grow corn. If the planting is too dense, in the later stages of growth, there will be no ventilation and light transmission between the corn plants, which will also affect plant photosynthesis. There are also cases where the supply of fertilizer and water in corn fields is not in place, and the corn plants lack nutrients. When these reasons are combined, the corn will naturally have convex tips.

Solution: When growing corn, you must pay attention to the relative density. It cannot be too thick or too thin. Planting too densely will harm corn production. Planting too sparsely will limit the production and sales of corn. 3. Insufficient nutrition leads to

When growing corn, if the fertilizer supply is insufficient, leading to nutrient deficiencies, baldness will also occur. When growing corn, when we use base fertilizer, in addition to some organic fertilizer, we also need Add some compound fertilizer. At the trumpet stage, apply fertilizer again. During the grouting period, fertilizer is also needed. When it comes to pest control and disease prevention, you also need to add some leaf fertilizer to ensure adequate nutrition. If corn has a nutrient deficiency and is not replaced in time, convex tips will also occur.

Solution: To grow corn, fertilizer must be in sufficient supply. In addition to some organic fertilizers, you also need to add some trace element fertilizers appropriately. Only with sufficient and comprehensive nutritional supply can corn grow healthily and happily. 4. Improper selection of varieties

This factor is also very important. You must know that there are not only one or two varieties of corn, but there are many varieties. If a good friend of the grower buys some fake seeds and The above situation will occur if the varieties are not suitable for you or are not suitable for local planting. Corn varieties also have genetics. If they are hybrid varieties and bald tips are introduced, this problem will also occur.

Solution: When buying corn seeds, be sure to buy professional corn seeds. There is no need to buy some inferior corn seeds for cheap.
