A Detailed Explanation of the Latest Key Points for Field Management of Chinese Yam
The main edible part of the Chinese yam is the tuberous root, and it is a herbaceous plant. It can be used both as food and as medicine, and the market demand for it in our country is very large. Now the planting area of Chinese yam is also continuously expanding along with market demand. However, during cultivation, field management work is very important, and many people end up with insufficient yields because of poor management. So today, the editor has brought you the key points for field management of Chinese yam. Let's take a look together!
1. Intertillage and weeding
Intertillage and weeding is an indispensable management task in Chinese yam cultivation. It is mainly to prevent weeds from robbing the Chinese yam of the nutrients it needs for growth, to improve soil permeability, and to enhance the growth capacity of the Chinese yam. However, pay attention to the depth of intertillage; it should not be too deep, to prevent damaging the roots of the Chinese yam. When weeding, if chemical weed control is used, it must be combined with manual pulling of weeds. After the Chinese yam emerges, appropriately spray a mixture of glyphosate and water. This can effectively achieve the purpose of weed control and will not affect the growth of the Chinese yam.
2. Water and fertilizer management
The growth cycle of Chinese yam is relatively long, so during cultivation the demand for nutrients is relatively large. Especially in summer, nutrient demand increases, so the fertilization interval should be shortened. The fertilization method is mainly broadcasting, and when fertilizing, attention must also be paid to doing drainage work well. Prevent waterlogging from affecting the growth of the Chinese yam root group, causing forked roots to form on the roots and reducing the quality of the Chinese yam tuberous roots. However, water should not be too little either, otherwise it will also reduce the yield of Chinese yam. Therefore, attention must also be paid to doing irrigation and drainage work well. When fertilizing, reasonably adjust the nutrient ratio in the fertilizer according to the growth condition of the Chinese yam and the soil, so as to meet the nutrients needed for the growth of the Chinese yam.
3. Controlling the growth of aerial tubers
During growth, Chinese yam produces many aerial tubers. Aerial tubers consume a large amount of nutrients, thus greatly hindering the growth of the Chinese yam tuberous roots and leading to reduced yield. However, aerial tubers can also very well balance nutrients and water; if water and fertilizer are insufficient, the aerial tubers will divert water and fertilizer to the tuberous roots. So we still need to retain a certain number of aerial tubers. When the stems and vines grow to the top of the trellis, appropriately spray growth regulators to prevent excessive vigor and at the same time inhibit the growth of aerial tubers. If there are too many aerial tubers, they can be removed manually when necessary to reduce nutrient consumption.
4. Pest and disease control
Pest and disease control work for Chinese yam is also very important. Pest and disease control work is mainly based on prevention, and field management should be strengthened with regular disinfection. Control the amounts of water and fertilizer well to prevent excessive amounts from causing waterlogging damage and fertilizer damage and resulting in losses. After entering summer, reasonably spray fungicides and insecticides according to the pest and disease situation. Especially in high-temperature and high-humidity environments, which are very favorable for the spread and breeding of pathogens. Therefore, prevention must be strengthened, and in the middle and late stages the focus of cultivation should be placed on disease prevention to increase the yield of Chinese yam.
The above is a brief introduction to the key points of field management of Chinese yam. The field management work of Chinese yam is very important and directly affects yield and cultivation benefits, so everyone must pay attention to it. That is all for today's introduction.
