The key points of Chinese yam planting

Chinese yam is a kind of edible and medicinal vegetable, which has a very high status in our country, and many people like to eat Chinese yam very much. Chinese yam is widely planted in our country, although it is simple to grow Chinese yam, but there are many places that need our attention. And there are many key planting points that can not be ignored. The following editor brings you the key points of yam planting, let's have a look!

1. Loose soil

The degree of looseness of the soil is very important for the growth of the rhizome of Chinese yam, and the degree of looseness used can promote the effective elongation and expansion of the rhizome of Chinese yam. When planting, the depth of the planting ditch should be dug to about 1 meter, which is soft enough to effectively raise the ground temperature and promote the germination of stem seeds. If the soil is not soft enough, the soil is hardened, the permeability is poor, and the yield and quality of yam are reduced. We can mix farm manure or crushed crop straw in the soil, which can not only improve soil fertility, but also enhance soil permeability, and create a good growth environment for yam.

2. Apply sufficient base fertilizer

Base fertilizer is the key to ensure the early growth of Chinese yam. In order to meet the nutrition needed for the growth of Chinese yam, base fertilizer must be adequate. The base fertilizer is mainly rotten farm manure and compound fertilizer, which must be fully mature to prevent the heat produced by fermentation after being applied in the field to burn out the rhizome and affect the growth of yam. If possible, an appropriate amount of biological fertilizer can also be applied, which can be fully mixed with the soil and put into the planting ditch. Then pour enough water and sow seeds when the soil temperature rises to about 16 degrees. After sowing, the soil should be covered with plastic film to improve the soil heat preservation, and then the film should be removed in June to promote the root tuber.

3. Treatment of seedlings

Chinese yam is often infected with some diseases and insect pests in the process of planting, such as root rot, blight and so on. These diseases will seriously harm the growth of Chinese yam, reduce the yield of Chinese yam and affect the economic benefits of planting. Therefore, before planting, we should disinfect the yam species, soak the yam with Shilaishi and other agents, and then spray sterilization in the planting ditch to sow, so as to reduce the phenomenon of dead yam at seedling stage. In spring, the phenomenon of insect pests is more serious, so we should properly spray phoxim and other chemicals to control pests and avoid injury of yam plants.

4. Protect stems and leaves

When the yam grows to the middle stage, the weather changes greatly, mostly on rainy days, and the humidity will increase. It is easy to cause all kinds of diseases and insects, so we should spray amiceda and other agents regularly to prevent it, protect the stems and leaves of Chinese yam, avoid injury and affect growth. About once a half a month, about 3 times. And we should carry out corresponding control according to the types of diseases and deal with the diseased plants in time to avoid unnecessary losses. And we should also pay attention to the removal of yam beans to prevent excessive consumption of nutrients and increase planting costs.

The above is a brief introduction of the key points of yam planting, there are many matters needing attention in yam planting, all of which require us to do a good job in the management of yam planting. We should prevent bad phenomena in the planting process and affect the planting efficiency. That's all for today's introduction. This article is for reference only. I hope it can help you all.
