How to Grow Chinese Yam to Increase Yield? A Detailed Guide to the Latest Planting Methods
Chinese yam, also known as earth potato, Huai Shan and so on, is a root vegetable. Chinese yam has a series of effects such as nourishing and strengthening the body, stopping diarrhea and aiding digestion. It also has the effect of preventing diabetes, and in China it is used to make dishes, processed into various products, and so on. Now many people are also growing Chinese yam, hoping for a high yield to gain more economic benefits. So how can we increase the yield of Chinese yam? Let me introduce it to you below!
1. Select superior varieties
First of all, before planting, we must choose good varieties, and we should choose varieties with high yield and strong disease resistance. Usually, disease resistance is an aspect that everyone overlooks when selecting seeds. The root and stem of Chinese yam can extend very far underground, and if disease resistance is not strong, it is very easy for it to suffer pest damage. Moreover, it is very difficult to detect, which naturally leads to a decline in yield, so attention should be paid to variety selection before planting. In addition, the same variety should not be used year after year, because at most after two years a better new variety will appear, and we should replace it in time to ensure our yield.
2. Build trellises properly
Not only is the root of Chinese yam very long, but the branches and leaves above ground are also very luxuriant. If no trellis is built, the branches and leaves will collapse and spread on the ground. The air permeability becomes extremely poor, which blocks photosynthesis and affects nutrient accumulation. The root and stem of Chinese yam lack nutrients and grow poorly, causing a decline in yield. Therefore, after the Chinese yam sprouts, we should build trellises in time, and a trellis height of about 1.8-2 m is sufficient. The trellis should be built in a “”-shaped way to improve the stability and wind resistance of the trellis, and attention should be paid to the distance between the trellises. This not only enhances the air permeability of the field, but also increases the yield.
3. Fertilizer and water management
Fertilizer and water management during the planting process of Chinese yam is very important. Chinese yam is a fertilizer-loving crop, so we should improve the fertility of the soil and apply sufficient base fertilizer before planting. Then, according to the growth of the Chinese yam, topdress in time. When applying organic fertilizer, attention should be paid to decomposition, otherwise it is easy to cause pest damage. Also pay attention to the nutrient ratio of the fertilizer, control the amount well, and do not over-apply nitrogen fertilizer, to prevent excessive vegetative growth of the Chinese yam. Chinese yam likes water but is not tolerant of waterlogging, so while ensuring that the soil is moist, we should prevent excessive accumulation of water. In rainy weather, drain water in time to prevent waterlogging damage, root rot, and reduced yield.
4. Pest and disease control
Pests and diseases are the main reasons for the decline in Chinese yam yield and severe shortages. Therefore, pest and disease control work must be strictly managed from before planting to harvest and even during storage. It is best not to grow Chinese yam continuously. If it is grown continuously, the probability of pests and diseases will be infinitely expanded. Strengthen management during the planting period, spray pesticides regularly to reduce pathogens, and when spraying, an appropriate amount of new high-fat film can be added to improve the efficacy of the pesticide. However, pay attention to the concentration, otherwise it will also inhibit the growth of Chinese yam.
The above are several methods for increasing the yield of Chinese yam. In fact, they are also some management tasks we should pay attention to when planting. In other words, increasing yield is closely related to our daily management. If management is poor, naturally the yield will decline. So I hope everyone can attach importance to daily management and strengthen their own planting techniques. That is all for today's introduction.
