Management techniques of Chinese Yam in the Middle and late stage

Yam is often said in our daily life Huaishan, it is both a medicine and a vegetable. It has great nutritional value, so it is also welcomed by many people. When planting yam, its management is very important. We need reasonable management according to the growth period of yam, among which the middle and late stage of yam needs to be paid attention to. So Xiaobian brought you the management technology of yam in the middle and late stages today. Let's take a look at it together.

1. Fertilizer and water management

In the middle and late stage of yam, fertilizer and water management is definitely indispensable. We should fertilize once when the stem and leaf of yam are covered with the whole frame surface. The main fertilizer is urea, which can be applied about 20kg per mu. Some potash fertilizer can also be applied appropriately, or appropriate foliar fertilizer can be sprayed to enhance the resistance of yam and improve yield. Although the drought tolerance of yam is relatively strong, in order to improve its yield. In case of dry weather, we should also pay attention to watering. However, in rainy days, it is necessary to eliminate accumulated water in time to avoid waterlogging, resulting in yam death due to accumulated water and hypoxia.

2, pest control

In the middle and late stages of yam, pests and diseases are also very many. Therefore, we should pay attention to the prevention and control of diseases and insect pests, among which the most common diseases and insect pests are anthracnose and root knot nematode. Anthracnose is one of the most common diseases in yam production, we should often observe the growth of yam. If anthrax-like diseases are found, then spraying should be carried out in time for prevention and control. At the initial stage of anthrax, mancozeb or carbendazim can be used for prevention and control, generally spraying once a week, continuously spraying for about three weeks.

3. Timely harvest

In the middle and late stage of yam, it is usually the harvest time of yam. The harvest period of yam is generally from October to the beginning of winter every year. At harvest time, start from one side of the bed and dig a pit about 60 cm square. Then shovel the soil along the yam about 10cm below the ground. Until you see the tip of the yam tuber at the bottom of the yam ditch, then grab the upper end of the yam with one hand, and shovel off the lateral root behind the rhizome with the other hand until you reach the root system attached to the stratum, so that you can take out a complete yam.

The above is a brief introduction to the management technology of yam in the middle and late stages. The management of yam in the middle and late stages is very important. If it is not properly managed, it will have a great impact on the yield and quality of yam. Therefore, we must pay more attention to it.
