How should yam be planted to increase yield?

Yam, also called sweet potato and Chinese yam, is a root vegetable. Yam has a series of effects such as nourishing and strengthening the body and stopping diarrhea and aiding digestion. It also has the effect of preventing diabetes, and in China it is used to make dishes and processed into various products. Now many people are also growing yam, hoping for high yields to obtain more economic benefits, so how can we increase yam yield? Let me introduce it to you below!

1. Select excellent varieties

First, before planting, we must choose good varieties, and should choose varieties with high yield and strong disease resistance. Disease resistance is usually an aspect that everyone overlooks when selecting seeds. The rhizome of yam can extend very far underground, and if disease resistance is not strong, it is very easy for it to suffer pest damage. It is also very difficult to detect, which naturally leads to reduced yield, so attention should be paid to variety selection before planting. Also, the same variety cannot be used year after year, because at most after two years better new varieties will appear, and we should replace them in time to ensure our yield.

2. Reasonable trellising

Yam not only has a very long root, but the branches and leaves above ground are also very lush. If no trellis is set up, the branches and leaves will collapse and spread on the ground. The air permeability becomes extremely poor, which hinders photosynthesis and affects nutrient accumulation. The yam rhizome lacks nutrients and grows poorly, causing yield decline. Therefore, after yam emerges, we must set up trellises in time, and the trellis height only needs to be about 1.8-2 m. The trellis should be set up in a “”-shaped way to improve the stability and wind resistance of the trellis, and attention should be paid to the distance between trellises. This not only enhances field air permeability, but also increases yield.

3. Fertilizer and water management

Fertilizer and water management during yam cultivation is very important. Yam is a fertilizer-loving crop, so we must improve soil fertility and apply sufficient base fertilizer before planting. Then, according to the growth of the yam, topdress in time. When applying organic fertilizer, pay attention to decomposition, otherwise it is easy to produce pest damage. Also pay attention to the nutrient ratio of the fertilizer, control the amount well, and do not overapply nitrogen fertilizer to prevent excessive vegetative growth of yam. Yam likes water but is not tolerant of waterlogging, so while ensuring the soil is moist, we must prevent excessive water accumulation. 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 and serious shortage of yam yield. Therefore, pest and disease control work must be strictly managed from before planting to harvest and even during storage. It is best not to continuously crop yam; if continuously cropped, the probability of pests and diseases will be infinitely expanded. Strengthen management during the planting period, spray pesticides regularly, 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 yam.

The above are several methods for increasing yam yield. In fact, they are also some management tasks we should pay attention to when planting. That is to say, increasing yield is closely related to our daily management. If management is poor, the yield will naturally decline. So I hope everyone can attach importance to daily management and strengthen their own planting techniques. That is all for today's introduction.
