Causes and Prevention methods of Maize with Root and Bud

In the process of corn sprouting after sowing, many people will encounter the phenomenon that there are no buds or buds and no roots, which brings great trouble to farmers, and many people often do not know what to do. So what is the reason why corn has roots and no buds? How to prevent it? Let's take a look at the detailed introduction with the editor.

I. the cause of occurrence

The main results are as follows: 1. Sowing quality: planted on the viscous soil, if the sowing is too deep, the soil permeability is poor, which will affect the seed germination.

2. Coating drug damage: many farmers use too much medicine when coating, and the coating is uneven, which will damage the germ of the seed and affect the normal germination.

3. Fertilizer burning seedlings: when applying base fertilizer or seed fertilizer, there are no good isolation measures, so that the seeds and thick fertilizer are based directly, which is very easy to cause sprouting or root burning.

4. The temperature is too low: after sowing, the temperature is low, but the soil moisture is high and the air permeability is poor, which affects the differentiation of seed buds.

5. Underground insect pests: after sowing, the buds or roots are eaten by underground pests, resulting in the seeds can not grow normally.

6. Herbicide damage: when weeding is carried out before and after sowing, the improper use of herbicides leads to the infiltration of the liquid and affects the germination and rooting of seeds.

7. Freezing injury: the seeds were not dried in time after harvest. When they were damaged by low temperature, the radicles and germs were frostbitten directly, resulting in their abnormal development.

8. Mechanical damage: in the process of seed production, the embryo or radicle is damaged by instruments, so that it can not germinate normally.

II. Preventive methods

1. Before sowing, seed selection, seed drying and other measures should be carried out to ensure the vigor of the seeds. When coating, it is necessary to control the application amount of chemicals to ensure uniform coating.

2. When sowing, the sowing depth should be controlled according to the humidity of the soil. When the humidity is high, it can be sowed lightly and late sowing at the same time. In case of heavy rain after sowing, it should be drained in time. Attention should be paid to the method when applying fertilizer, and it is not appropriate to put seeds in direct contact with fertilizer.

3. The use of herbicides should be carried out in strict accordance with the standard. In case of low temperature, preventive measures should be taken to reduce the degree of freezing damage of seeds.

The above is the introduction of the reasons why corn has roots and no buds and how to prevent it. I hope it can help you. If you want to know more about it, please follow us.
