Causes and prevention methods of carrot malformation

Carrot is one of the common vegetables in our life, it has high nutritional value and is deeply loved by people, but in the process of carrot planting, the most common problem is deformity. So what is the reason for the malformation of carrots? How to prevent and cure? Let's take a look at the detailed introduction.

1. Soil causes

When a carrot grows in normal soil, its roots will swell normally, but there may be some rubbish, such as plastic film, when there are hard objects such as stones, bricks and tiles in the soil. These substances will hinder the growth and expansion of carrot roots, resulting in abnormal expansion of lateral roots, forming bifurcated or curved abnormal roots. In addition, the phenomenon of growth deformity will also occur when the soil is hardened or planted on the clayey soil.

Prevention and control methods: when planting carrots, we must choose loose and fertile soil, clean up the stones and sundries in the soil, lest sundries affect the normal expansion of carrot roots, and combine ploughing and loosening soil during growth to avoid root exposure.

2. Fertilizer reasons

When immature organic fertilizers or over-concentrated chemical fertilizers are applied during planting, they will emit a lot of heat during decomposition, resulting in root burning, resulting in fleshy roots deviating from growth, bending and bifurcating. In addition, partial application of nitrogen fertilizer will also make the internal growth too fast, the epidermis can not keep up with the internal growth, resulting in bifurcation.

Control methods: the base fertilizer applied before sowing should be completely rotten, the concentration of chemical fertilizer should be paid attention to, it should not be in direct contact with the root system, or the way of sprinkling with water should be adopted to reduce the fertilizer concentration.

3. Watering reason

During carrot root expansion, excessive watering will lead to excessive internal water absorption and rapid expansion of the root system, but the growth of root bark is relatively slow, so the phenomenon of root cracking is chosen.

Prevention and control methods: when the main root is dilated, the soil should be kept moist, but it should not be watered too much, and drainage measures should be taken when Rain Water is more, so as to prevent the root system from absorbing too much water and splitting the root.

4. Underground insect pests

During the growth of the main root, the underground pests in the soil will bite the main root and inhibit the growth of the main root, resulting in the expansion of the lateral root and abnormal growth.

Prevention and control methods: we must pay attention to pest control, gather land preparation and ploughing when planting, eliminate the underground, and plant chemicals mixed with soil to make poisonous soil to kill and exterminate underground pests.

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