There are often many food growers who reflect such a problem, that is, the corn planted by their own family has a baldness phenomenon, which seriously affects the corn phase and quality, and will also reduce production. So what is the cause of the phenomenon of corn baldness? How should we prevent it? Let's take a quick look together.
First, the weather reasons
The weather causes the occurrence of corn baldness. It is believed that most of the farmers' friends should first think of it. There are two main reasons for the weather phenomenon, one is rainy and the other is high temperature. If the corn field has been hot and lacks water, it will affect the development of the ear of corn until it affects the later stage of the result. The other is that when the corn flowering pollination stage encounters continuous rain, it will also make the corn bald. It is difficult to control this situation in open field cultivation. If you are in a greenhouse, you can take certain measures. Specifically consider the actual situation.
Second, the plant is too thick
If the seed is too thick and grows to the middle and late stages, the corn plants cannot be ventilated and transmitted, which will also affect photosynthesis. In addition, the supply of water and fertilizer in the cornfield is not in place, and the malnutrition of the corn plants is combined. These reasons are combined and the corn will naturally appear convex.
Solution: To grow corn, you must pay attention to the density, too thick and too thin. The species is too thick and will affect the yield of corn. The species is too thin and the yield of corn will also decrease.
Third, the nutrition is not comprehensive
If the corn supply is insufficient, it will lead to deficiency, and there will be baldness and corn. When we apply the bottom fertilizer, in addition to some farmyard manure, we need some compound fertilizer. In the big bell period, the fertilizer is added again. During the filling period, the fertilizer is also needed. At the stage of pest control and disease prevention, we must add some foliar fertilizer to ensure adequate nutrition. If the corn is deficient, and it is not replenished in time, there will be a spurt.
Solution: Plant corn, fertilizer must be adequately supplied. In addition to some farmyard manure, it is necessary to supplement some micro-fertilizers. The nutrient supply is sufficient and comprehensive, and corn can grow healthily.
Fourth, improper selection of varieties
This reason is also very crucial. It is necessary to know that there are only one or two varieties of corn, but there are many kinds. If the grower friend sells some fake seeds and is not suitable for himself, or is not suitable for local cultivation, These will happen. Maize varieties are also hereditary. If they are hybridized, they will be mixed with baldness. This phenomenon will also occur.
Solution: Buy corn seeds and be sure to buy regular corn seeds. Don't try to buy cheap inferior corn seeds.
