A Detailed Explanation of the Latest Key Points for Growing Chinese Yam
Chinese yam is an edible and medicinal vegetable that can also be used as medicine. It holds a very high status in our country, and many people also very much enjoy eating Chinese yam. Chinese yam is grown over a very wide range in our country. Although growing Chinese yam is simple, there are many aspects that require our attention. And there are also many key growing points that cannot be ignored. Below, the editor brings you the key points for growing Chinese yam. Let's take a look!
1. Loose soil
The degree of soil looseness is very important for the rhizome growth of Chinese yam. An appropriate degree of looseness can promote the effective elongation and swelling of the Chinese yam rhizome. When planting, the planting trench should be dug to a depth of about 1 m. Sufficiently soft soil can effectively raise the soil temperature and promote the germination and emergence of the seed stems. If the soil is not soft enough, the soil will become compacted and have poor permeability, reducing the yield and quality of Chinese yam. We can mix farmyard manure or crushed crop straw into the soil. This can both improve soil fertility and enhance soil permeability, creating a good growing environment for Chinese yam.
2. Apply sufficient base fertilizer
Base fertilizer is the key to ensuring the early growth of Chinese yam. In order to meet the nutrients needed for the growth of Chinese yam, the base fertilizer must be sufficient. The base fertilizer is mainly composed of fully decomposed farmyard manure, with compound fertilizer as the main type. Farmyard manure must be fully decomposed to prevent it from fermenting after being applied to the field and generating heat that burns the rhizome and affects the growth of Chinese yam. If conditions permit, an appropriate amount of biological bacterial fertilizer can also be applied. After fully mixing it with the soil, place it into the planting trench. Then water thoroughly. Sow when the soil temperature rises to about 16 degrees. After sowing, cover with soil and mulch to improve soil heat retention, then remove the mulch in June to promote the downward growth of the tubers.
3. Treat the seedlings
During the growing process, Chinese yam often becomes infected with some diseases and pests, such as root rot and damping-off, and these diseases will seriously harm the growth of Chinese yam, reduce its yield, and affect the economic benefits of cultivation. Therefore, before planting, we should disinfect the Chinese yam seeds. We can use agents such as Shi Le Shi for soaking treatment, then spray a fungicide in the planting trench before sowing to reduce the phenomenon of dead plants during the seedling stage of Chinese yam. In spring, pest problems are relatively serious, so we should appropriately spray agents such as phoxim to control pests and avoid injury to the Chinese yam plants.
4. Protect stems and leaves
When Chinese yam grows to the middle stage, the weather changes greatly, with many rainy days, and humidity will increase somewhat. This can easily cause various diseases and pests, so we should regularly spray agents such as Amistar for prevention, protecting the stems and leaves of Chinese yam and avoiding injury that affects growth. About once every half a month, about 3 times in total is enough. And we should carry out corresponding control according to the type of disease, promptly handling diseased plants to avoid unnecessary losses. We should also pay attention to removing the aerial tubers of Chinese yam to prevent excessive consumption of nutrients and increased cultivation costs.
The above is a brief introduction to the key points for growing Chinese yam. There are many matters to note in Chinese yam cultivation, and all of them require us to do a good job in management during planting. We must prevent undesirable phenomena from appearing during the growing process and affecting cultivation benefits. That is all for today's introduction.
