Why is there no root and no bud in corn planting? There are so many reasons behind it.

In recent years, many farmers have reported that the phenomenon of having roots and no buds has occurred. This phenomenon is generally that the roots develop well, but there are no buds, or a little bit of the head is exposed, and then no longer grow. Why on earth is this? What are the causes? How to prevent it?

First, the "nine reasons" that corn has roots and no buds.

1. Sowing too deep: if corn is sown too deep, it will lead to poor air permeability in the soil, which will often affect the germination of buds and lead to roots without buds.

2. Excessive soil moisture: due to widespread rainfall across the country this year, there are too many Rain Water in the fields, similar to sowing too deep, which will also lead to poor air permeability, so that corn seeds can not germinate normally.

3. Drug damage of seed coating agent: when the brothers are coated by themselves, the dosage is large and the coating is uneven, which is easy to cause damage to the germ or radicle and affect the normal development.

4. Chemical fertilizer seedling burning: when seed and fertilizer are sown at the same time, there is no good isolation, so it is easy to burn buds or roots.

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

6. Underground pests: in the early stage, underground pests gnawed buds or roots, resulting in abnormal growth of seeds.

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

8. Seed freezing injury: the hybrids were not dried in time after harvest, suffered from low temperature frostbite, and frostbitten radicle or germ, resulting in non-normal development.

9. Seed injury: in the process of seed production, the germ or radicle is damaged by instruments, so that the bud or root can not germinate normally.

Second, how to prevent and deal with corn with roots and no buds?

[preventive methods]

1. Seed selection and drying before sowing to ensure seed vigor. Seed coating agent must be used to prevent underground pests, but the dosage must be controlled and the uniformity of coating must be ensured.

2. Control the sowing depth according to the soil moisture, the humidity is large, the sowing depth is 3-4 cm; the humidity is small, the sowing depth is 4-5 cm.

3. For the land with large soil moisture, late sowing is recommended. In case of heavy rain after sowing, the stagnant water in the field should be discharged in time.

4. deep application of base fertilizer to ensure that the isolation of seed fertilizer is more than 8 cm, and compound fertilizer and urea can not be used as mouth fertilizer.

5. The dosage of herbicides must be strictly controlled and should not be administered before heavy rain or in windy days.

[how to deal with it? ]

1. If the occurrence rate is less than 10%, there is no need to deal with it.

2. If the occurrence rate is 20-40%, it should be replanted in time.

3. If the occurrence rate is more than 50%, it is necessary to buy early-maturing varieties and destroy the seeds in time.

When there are problems in the process of corn planting, it is not terrible to find the right reasons and make corresponding solutions in time. Do not plant without asking and blindly respond, communicate more, learn more, and believe that corn will be high-yielding.
