What to do if corn has roots but no buds

The reason why corn has roots but no buds

1. Sowing quality: In clay soil, if sowing is too deep and the soil has poor air permeability, it will affect the germination of young shoots.

2. Chemical damage of seed coating agent: When the old irons coat themselves, the amount of medicine is large and the coating is uneven, which will easily cause damage to the embryo or radicle and affect normal development.

3. Burning seedlings with chemical fertilizer: When seeding and fertilizer are sowed at the same time, it is easy to burn buds or roots if they are not well isolated.

4. Low temperature and high humidity: After sowing, the temperature is low, the soil moisture is too large, and the air permeability is poor, which affects the normal differentiation of buds and roots.

5. Underground pests: Early underground pests gnawed buds or roots, causing seeds to fail to grow normally.

6. Herbicide damage: Incorrect application period, large dosage or high permeability of sandy soil will cause the liquid to penetrate into the ground and affect the normal development of buds and roots.

7. Seed freezing damage: Hybrid seeds are not dried in time after harvest, and they suffer from low temperature freezing damage and frostbite the radicle or embryo, resulting in failure of normal development.

8. Seed injury: In the process of seed production, the embryo or radicle is damaged by the equipment, causing the bud or root to fail to germinate normally.

Preventive methods for corn with roots but not buds

1. Pick seeds before sowing and dry them to ensure seed vigor. The seed coating agent must be used for coating to prevent underground pests, but the dosage must be controlled during coating and the uniformity of the coating must be ensured.

2. Control the seeding depth according to the soil humidity. If the humidity is high, sow two fingers; if the humidity is low, sow three fingers.

3. For plots with large soil moisture, it is recommended to sow later. In case of heavy rain after sowing, drain the field water in time.

Diseases often occur in the process of corn planting, and the phenomenon of buds without roots is also common, but if not controlled in time, corn seedlings will be uneven.
