Causes and control methods of abnormal root of radish

Radish is a common vegetable in our life, which is rich in nutrition and deeply loved by people, but the abnormal growth of fleshy root will occur during the growth of radish, which seriously affects the yield of radish. So what is the reason for the abnormal root of radish? How to prevent and cure it? Let's take a look.

1. Planting is too dense

If the planting is too dense, it will cause the root system of radish to squeeze each other, which will lead to the bending of the main root, the vigorous growth of lateral root, and finally the abnormal root system of radish.

Prevention and control methods: reasonable close planting, using the method of hole sowing, the row spacing of plants in each hole is 20 × 25 cm, generally sowing 5-7 seeds in each hole, and it should be dispersed. Chicken seedlings should be kept in time when they emerge and grow to 2-3 true leaves, 2 seedlings in each hole, and one strong seedling in each hole when they grow to 5 true leaves.

2. Soil viscous weight

If the cultivated soil has impurities such as bricks, roots, waste plastic film, or the soil itself is relatively sticky, the growth of radish will be hindered, resulting in abnormal roots.

Prevention and control methods: select sandy loam or loam with deep soil layer and rich in organic matter, and prepare the soil before planting, so that the soil is loose, flat, free of gravel, persistent roots and other obstacles.

3. Improper fertilization

If immature organic fertilizer or farm manure is applied during planting, the fertilizer will emit a lot of heat during fermentation and decomposition, which burns the growth nodes of the main root, resulting in bifurcation of the root system. In addition, if the radish lacks boron, the root growth will be distorted.

Prevention and control methods: when applying base fertilizer, we must ensure that organic fertilizer and farm manure are applied after full maturity, and attention should be paid to topdressing in the later stage. It is not appropriate to directly contact the fertilizer with the root system so as not to cause burns. Boron deficiency can add an appropriate amount of borax to the base fertilizer, generally one kilogram per mu can meet the boron demand of radish during the whole growth period.

4. Underground pests

Many underground pests will also cause abnormal roots, such as grubs, mole crickets, golden needles, ground tigers, etc., if they are not properly controlled, they will continue to eat the main root of radish, resulting in lateral root expansion, resulting in abnormal roots.

Prevention and control methods: the control of underground pests must be thorough, the soil should be deeply turned over during soil preparation, the residual plants of weeds should be removed, the sources of insects should be eliminated, and poisonous soil can be sprinkled and killed if possible, and trichlorfon, dichlorvos and other chemicals can be used to control the roots in the period of pest outbreak, but pay attention to the concentration.

The above is the introduction of the causes and prevention methods of the abnormal root of radish. I hope it can help you. If you want to know more about it, please follow us.
