Causes and preventive measures of the latest deformity of sweet potato

Sweet potato, also known as sweet potato, sweet potato, is an annual herb, rich in protein, starch, vitamins and minerals, but also anti-cancer, diabetes prevention and weight loss effects, set edible and medicinal value as one. However, when sweet potato is planted, there will be abnormal growth phenomenon, which will cause certain losses to farmers. What is the reason for sweet potato abnormality? Let's take a look at the pro-farming network together.

cause of deformity

1. Continuous cropping and lack of nutrition: If sweet potato is continuously cropped for a long time, it will cause serious damage to pests and diseases, thus causing deformity. In addition, many farmers are accustomed to applying nitrogen, phosphorus and potassium fertilizers during planting, especially a large amount of nitrogen fertilizer, resulting in vigorous growth of vines, which affects the absorption of other trace feeds by plants. Calcium, boron and other elements are essential substances for plant growth. Lack of these trace elements leads to thinning of sweet potato skin and loss of elasticity, resulting in cracking and deformity.

2. Drug residues: When planting sweet potatoes, excessive use of the previous crop drugs leads to certain drug residues when planting sweet potatoes. These drugs will affect the growth of sweet potatoes and cause growth abnormalities over time.

3, the application of organic fertilizer is not completely decomposed: the above mentioned lack of trace elements, and organic fertilizer or farm manure is rich in these elements, can meet the growth needs of sweet potato, but some farmers in the application of these organic fertilizers are not completely decomposed, resulting in the application of organic fertilizer in decomposition will emit a lot of heat, resulting in burning root phenomenon, resulting in sweet potato tuber growth deformity.

4, pests and diseases: sweet potato in planting will suffer a lot of pests and diseases, these pests and diseases will cause damage to it, such as stem nematodes, black spot disease, insects, grubs and other pests will cause deformity.

There are many other reasons for sweet potato deformity, such as variety, heavy soil viscosity or a large number of stones, stones and other hard objects, improper management of water and fertilizer, or early occupation of nutrients in the field.

preventive measures

In view of the above causes of deformity, the right medicine to prevent deformity.

1. Continuous cropping will cause serious pest damage and cause deformity. Therefore, we should rotate crops reasonably and rotate crops with other crops to avoid losses caused by continuous cropping. In addition, fertilization should be reasonably matched, not single or partial application, so as to avoid excessive growth of plants and affect the absorption of trace elements.

2. Pay attention to the dosage and concentration of drugs, check the drug residue status when planting, and try to avoid plots with excessive drug residues.

3. When applying organic fertilizer and farm manure, it must be completely decomposed before application.

4. Attention must be paid to the prevention and control of diseases and insect pests. Diseases and insect pests should be dealt with in time and corresponding measures should be taken to prevent and control them.

5. Select varieties with high yield, excellent yield and strong disease resistance during planting. Strengthen water and fertilizer management after planting. Water and fertilize according to the growth status of plants and climate change in a planned way, so as to avoid skin cracking and deformity when sweet potato is rapidly expanded.

The above is the cause and preventive measures of sweet potato deformity brought by pro-agricultural network. I hope it can help you. If you want to know more about sweet potato planting knowledge, please pay attention to pro-agricultural network.
