Causes and Preventive measures of Grain deficiency and baldness in Maize

Corn is one of the most important crops in China, is the main source of income of many farmers, its yield is related to the economic benefits of farmers, but in planting because of some factors will often lead to corn grain baldness, seriously affecting the yield and quality. So what is the cause of grain deficiency and baldness in corn? How to prevent it? Let's take a look.

First, the reason for baldness

The main results are as follows: 1. High planting density is one of the main reasons for grain deficiency and bald tip of maize. Too much planting density and poor permeability lead to the mutual grabbing of nutrients among maize, so the phenomenon of grain deficiency and bald tip appears.

2. During the period of maize flowering and pollination, if the temperature is high and the soil moisture is insufficient, the life span of pollen and filaments will be shortened. During pollination, rainy weather and drought will affect its normal flowering and pollination. Poor pollination will lead to the phenomenon of grain deficiency and baldness.

3. The continuous use of drugs or the residue of drugs in the previous crop will cause normal drug damage to corn, resulting in a word for its growth, and the growth period will be delayed or without male selection, resulting in the loss of insemination, resulting in the occurrence of grain deficiency and baldness.

4. The bald tip of corn is also related to its variety and seed quality. some vendors will sell poor quality planting or adulterate substandard varieties in order to make more profit.

II. Preventive measures

The main results are as follows: 1. For the selection of improved varieties, the phenomenon of grain deficiency and baldness of some varieties is more serious, so the varieties adapted to the local climate should be selected as the main varieties.

2. Sowing time should be controlled well, temperature and light are the main factors affecting its growth, and its seed germination temperature is above 10-12 degrees, so it is necessary to sow seeds in time when the temperature is stable above 10 degrees.

3. The planting density should also be reasonable, not too dense or too thin, too dense will affect photosynthesis, affect the normal pollination of plants, resulting in grain deficiency and baldness. Too sparse will lead to low yield, generally controlled at about 3500 plants per mu, to go weak and stay strong.

4. For the fields with late development or poor pollination, artificial pollination should be carried out in time to reduce the incidence of low grain deficiency and baldness.

The above is the introduction of the causes and preventive measures of grain baldness in corn. I hope it can help you. If you want to know more about it, please follow us.
