The latest key points of field management of Chinese yam

The main edible part of Chinese yam is root tuber, which is a kind of herb. It is both edible and medicinal, and the market demand in our country is very large. Now the planting area of Chinese yam is also expanding with the market demand. However, field management is very important when planting, and many people lack production as a result of poor management. So the editor brings you the key points of field management of Chinese yam today. Let's have a look!

1. Ploughing and weeding

Weeding by ploughing is an indispensable management work for planting Chinese yam. The main purpose is to prevent weeds from grabbing the growth nutrition of Chinese yam, improve the soil permeability and enhance the growth ability of Chinese yam. However, we should pay attention to the depth of ploughing, should not be too deep, to prevent damage to the root of yam. If chemical weeding is used in weeding, it must be combined with manual weeding. When the Chinese yam emerges, it should be properly sprayed with the mixture of grass cover and water. It can effectively achieve the purpose of weeding, and will not affect the growth of yam.

2. Water and fertilizer management

The growth cycle of Chinese yam is relatively long, so the geese have a greater demand for nutrition when planting. Especially in summer, the demand for nutrition increases, so it is necessary to shorten the interval of fertilization. The main method of fertilization is spreading, and attention should be paid to the drainage work when applying fertilizer. Prevent stagnant water from affecting the growth of yam, leading to the formation of forked roots and reducing the varieties of yam tubers. But the moisture should not be too little, otherwise it will also reduce the output of yam. Therefore, we should also pay attention to the work of drainage and irrigation, and reasonably adjust the proportion of nutrients in fertilizer according to the growth of yam and soil, so as to meet the nutrition needed for the growth of yam.

3. Control the growth of yam beans.

Chinese yam produces a lot of yam beans when it grows. Yam beans will consume a lot of nutrients, so it will cause great hindrance to the growth of yam root tuber, resulting in a decline in yield. However, yam beans can also balance nutrient water. If there is not enough water and fertilizer, yam beans will turn water and fertilizer to root tubers. So we still have to keep some yam beans. When the stem vine grows to the top of the frame, it is necessary to properly spray growth regulators to prevent overgrowth and inhibit the growth of yam beans. If there are too many yam beans, they can be removed manually if necessary to reduce nutritional consumption.

4. Pest control

The pest control of Chinese yam is also very important. The prevention and control of diseases and insect pests is mainly based on prevention, so it is necessary to strengthen field management and disinfect regularly. Good control of the amount of water and fertilizer, prevention and control of excessive amount of water and fertilizer damage, resulting in losses. After entering the summer, we should spray antibacterial insecticides reasonably according to the situation of diseases and insect pests. Especially in the environment of high temperature and humidity, it is very beneficial to the spread and breeding of germs. Therefore, we must strengthen prevention, the middle and later stage of price planting focus on disease prevention, to improve the output of yam.

The above will be a brief introduction to the main points of field management of Chinese yam. The field management of Chinese yam is very important, which directly affects the yield and planting benefit, so we must pay attention to it.
