What should I do with radish bifurcation? Prevention of radish bifurcation

It is believed that many vegetable farmers often have a problem in growing radish, that is, radish bifurcation will seriously affect the quality of radish, as well as the market price. So when planting radish, we must prevent radish bifurcation in time, so what is the cause of radish bifurcation? How to prevent it? Let's have a look with the editor.

1. Seed quality

When selecting aged seeds when sowing, the vigor of such seeds is weak and the germination is poor, which will affect the growth of the young root tip, and some radicles will be destroyed and bifurcate easily. Due to poor pollination, seeds harvested in the rainy season are very easy to form seeds without embryos or poor embryo development. When sowing these seeds, the fleshy roots are easy to bifurcate.

Preventive measures: select high-quality and high-yield varieties with straight fleshy roots and not easy to bifurcate, so as to avoid bifurcations in planting, try to choose fresh, full and fully developed new seeds of the same year, and try not to choose old seeds of the next year.

2. Soil causes

When there is always gravel, bricks, roots and other hard objects in the soil, the growth of fleshy roots will be hindered, and bifurcations will occur. The main roots of shallow and hard tillage layers are easy to be blocked, promoting the growth and development of adventitious roots and producing bifurcations.

Preventive measures: before planting radish, the land must be ploughed deeply and not less than 25 centimeters. After several times of fine raking, the tillage layer should be deep and loose. At the same time, it should be combined with soil preparation to pick up hard sundries such as bricks, stones and tree roots in the soil.

3. Fertilizer and water management shall not be allowed

Excessive or uneven fertilization may cause radish root tip to be affected by high concentration of soil ions, which will promote adventitious root growth and cause carrot bifurcation. If the radish taproot is not watered in time during the period of radish taproot expansion, the soil will be hard and the taproot can not be bifurcated.

Preventive measures: farm manure must be applied after full maturity, chemical fertilizer must be spread evenly, adequate water supply should be ensured during the expansion period of the main root, so as not to dry the soil, and watering must be thoroughly watered.

4. Underground insect pests

Underground pests such as mole cricket and grub bite the main root of carrot, which destroys the main root and promotes the growth of adventitious root.

Preventive measures: in the radish rhizome expansion period, timely irrigation to control grubs and other underground pests to avoid their harm, agents should choose phoxim and other high-efficiency and low-toxic pesticides to reduce pesticide residues.

The above is about the radish bifurcation reasons and preventive measures, hope to help you, want to know more related knowledge, please follow us.
