Causes and preventive methods of root cracking of carrots

Carrot root cracking will seriously affect the yield and quality. Basically, carrots do not have any commodity value after root cracking, which causes huge economic losses to farmers. So what is the reason why carrots split their roots? How to prevent it? Let's take a look at the detailed introduction.

1. Uneven water supply

The main reason for carrot root cracking is that the soil water supply is uneven in the process of fleshy root growth, especially in the early stage of soil drought and water shortage and epidermis hardening. In the later stage, Rain Water or irrigation more, resulting in excessive water absorption, internal cell division accelerated, and the hardened surface can not grow accordingly, resulting in root cleavage.

Prevention: during the growing period of carrots, it is necessary to maintain a uniform supply of water, especially in the early stage to keep the soil moist, so as to avoid the situation of Rain Water in the later stage.

2. Partial application of nitrogen fertilizer

Nitrogen fertilizer can promote the growth of carrots. In order to increase the yield, many farmers tend to apply nitrogen fertilizer rather than other fertilizers, which leads to the vigorous growth of carrot roots and accelerates the rate of root splitting.

Control methods: in the growth of carrots, fertilization should be reasonable, fertilization at seedling stage should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, single application of nitrogen fertilizer is strictly prohibited in the middle and later stage, and the application of phosphorus and potassium fertilizer should be increased to increase yield and reduce root cracking.

3. Boron deficiency

Carrots have less demand for boron, but boron is very important in the later growth stage of carrots. It can improve the quality of carrots and make the growth of fleshy roots more developed. If carrots are seriously boron deficient, the transport of nutrients will be hindered, and the hindrance of nutrient transport will lead to root cracking of carrots.

Preventive method: 0.2-0.3% boron fertilizer solution can be sprayed during the carrot expansion period, which can significantly improve the yield and quality and reduce root cracking.

4. Soil causes

Carrots like to grow in a loose and fertile soil environment. If they are planted in clayey or hard soil, they will be blocked when the fleshy roots expand, resulting in bifurcations, split roots and so on.

Prevention method: so when planting, it should be planted in loose and fertile soil. Before planting, it should be combined with soil preparation, clear the hard objects such as stones in the field, and rake fine and level it at the same time.
