The latest causes of malformation in Maize

Corn malformations will not only have a great impact on the quality and yield of corn, but also do great harm to the economic interests of farmers. Corn malformations include 15 abnormal varieties, such as bald tip ear, missing grain ear, empty ear, bouquet ear and so on. Many friends think they take good care of themselves, but they don't know why they still have these problems. Also do not know what the specific cause of the deformity is, let the editor tell you about the cause of the corn deformity!

1. Drought

Drought is one of the main causes of corn deformities, too dry or continuous dry weather, farmers did not do a good job of replenishing water in time. Resulting in the lack of water in the land and air, so that the water content in the soil decreases rapidly, while corn does not have enough water absorption, which has a great impact on the absorption and transport of nutrients in corn. As a result, the fruit can not balance and evenly absorb nutrients, resulting in abnormal phenomenon. And drought will not only affect the development of maize on the ground, but also inhibit the extension of maize roots, resulting in the further deterioration of maize absorption system and transport capacity, resulting in deformities.

2. High temperature

Continuous high temperature weather will affect the photosynthesis of maize, weaken the intensity, reduce the accumulation of dry matter in maize, and high temperature will also force corn to speed up various reactions in the process of growth and development, resulting in shortening the process of each growth stage. completed ahead of schedule. As a result, the female ear of maize becomes less and the ear becomes smaller, the number decreases, the vitality of pollen is reduced, and the male ear can not blossom, which affects the pollination and fertilization process in the later stage.

3. Lack of fertilizer

The growth ability of corn is strong, the fertilizer needed is also relatively large, the demand for nutrition can not be single, it is more comprehensive, if there is a lack of fertilizer or other nutrients needed by corn in the growth process. For example, light, etc., especially in the maize fruit expansion period and flowering period, the lack of any of the same nutrients, corn will eventually produce deformities and may be diseases and insect pests. For example, lack of nitrogen fertilizer may cause bald spike, lack of phosphate fertilizer may cause lack of grain ear, and so on. Therefore, in the process of planting, we must ensure adequate nutrition for the growth of corn.

4. Variety

Corn is also divided into many varieties, and the growth and yield of each variety are very different, so different varieties naturally form the incidence of deformities. But the reason for the variety is not due to its own genetic problems, for example, some varieties of corn bracts are very tight and short, encounter overcast and rainy weather, can not effectively stop Rain Water, so that Rain Water easily flow into the ear, resulting in ear sprouting. Of course, some are caused by genes, such as sweet corn genetic varieties, in the ear period encountered a long period of low temperature weather is more likely to occur abnormal phenomenon, the formation of barbell-like abnormal corn.

The above four are the main causes of corn deformities, of course, there are far more than these, such as diseases and insect pests, pharmaceutical causes and so on. In the final analysis, it is because of improper management that there is the possibility of these problems, so we must master a set of correct management methods in planting, so that corn has a good growth environment. Only in this way can we effectively reduce the incidence of malformations.
