The cause of the deformity of Chinese yam

The normal shape of Chinese yam is straight long column, but with the expansion of cultivated area in recent years, there are a lot of problems in planting, such as many medicine farmers grow abnormal yam. Abnormal Chinese yam does not appear on the market, affecting economic benefits, so what is the cause of Chinese yam deformity? Let's take a look at the pro-farm network.

1. There are hard objects in the soil

When planting yam, it is necessary to open the soil 1-2 meters deep and flatten the soil to crush it. This is to prevent malformations caused by foreign bodies in the soil that hinder the growth of Chinese yam. However, if the trench is not careful, there are stones, gravel and other hard objects in the soil, and the hard objects are also crushed when filling the soil, which leads to one of the reasons for the abnormal growth of yam.

2. Improper fertilization

When planting Chinese yam, some medicine farmers apply all kinds of base fertilizer to it in order to make it grow faster and yield higher, which leads to excessive amount of base fertilizer or sufficient mixing with soil, which leads to direct contact between seedlings and bottom fertilizer, causes partial buds and roots to cause root burning, causes tuber growth and deformation, and appears abnormal shapes such as bifurcations and multiple heads.

3. Application of immature organic fertilizer

Sufficient nutrients are needed in the growing period of Chinese yam, so in addition to applying sufficient base fertilizer, it is necessary to constantly apply fertilizer to supplement nutrients, and the application of organic fertilizer is the best, which is rich in various elements and can improve the growth of yam. However, it is not completely mature when it is applied, which makes it fermented and heated after application, which will also cause the phenomenon of root burning and make the yam appear serpentine and gourd-shaped deformities.

4. Unbalanced nutrition

In the yam expansion period, a variety of nutrients are needed, such as common potassium, calcium, boron and many elements, but some drug farmers always apply one kind of fertilization in order to save time and effort, resulting in too single nutrition and lack of other nutritions. appear bifurcation, flat head and other deformities.

5. Insect pests

Many pests harm the roots and tubers of Chinese yam, such as golden needle worms, grubs, mole crickets, root-knot nematodes and other common pests. They gnaw or bite off the roots and tubers of Chinese yam, resulting in slow growth of yam and abnormal tubers.

The above is the introduction of the reasons for the malformation of yam brought by the pro-agricultural network, the reasons leading to the malformed yam are generally on the above, we should pay attention to planting, more agricultural knowledge, please pay attention to the pro-agricultural network.
