The propagation method of the latest Chinese yam

Chinese yam, also known as Huaishan, must be a kind of traditional Chinese medicine vegetable that everyone is very familiar with. It has a very high medicinal value and has a long history of planting and eating in our country. Now the market of Chinese yam is relatively good, and more and more people are planting it. How to reproduce when planting Chinese yam is a very important work, which is the key to ensure that it can be planted normally and continuously. The following editor has brought you the breeding method of yam, let's have a look!

1. Reed head reproduction

When the yam is ripe from October to November every year, dig out the root of the yam, and then select the Reed head which is not long in the neck, full and full, stout and free from wounds, diseases and insect pests as the breeding mother. Then break the Reed head about 18 cm and put it in the sun for about 3 days to promote wound healing. Then dig holes in the soil for storage, when the overwintering ground temperature is kept above 5 degrees, do a good job of deep fertilization. The row spacing is controlled at about 40 cm, and the plant spacing is about 18 cm, and the border is ready for planting. Watering in time after planting, the seedlings can take root after about 2-3 weeks of normal management.

2. Plant bud propagation

Plant bud propagation is mainly carried out through yam beans. First, the yam beans are picked after the yam is ripe, and then stored in dry sand. Take it out around February to April in spring, and then bask it in the sun for a few days, because the germination ability of yam beans is relatively strong, and the disease resistance is not weak. Therefore, there is usually no need for sprouting, and the plant spacing should be controlled at about 10-22 cm when sowing. Dig a good sowing hole, each hole into about 3 yam beans, and then cover 5 centimeters of fine soil. Do a good job in sowing management, and the seedlings will emerge in about two weeks.

3. Root propagation

Root tuber propagation, as the name implies, is to use tuber roots for propagation treatment, first pick out the left and right female roots with a length of 1 meter and a diameter of about 3 centimeters. Then cut the root into small segments of about 18 cm, and mark each segment to facilitate later identification and management. After marking, put the cut section into the lime powder and dip in the right amount of lime powder. Then expose it to the sun, pay attention to the occurrence of wind and rain when drying seeds, so as to avoid causing root injury. When cracks appear in a small section, the temperature is above 13 degrees and the average low temperature is about 11 degrees. When planting, we should pay attention to digging ditches, maintaining planting density, digging holes, putting root vertically, covering soil and ridging, and doing a good job of management.

The above is a brief introduction to the reproduction methods of Chinese yam, and there are many reproduction methods of Chinese yam. No matter what kind of breeding methods have different advantages and disadvantages, and also adapt to different environments and planting scale. Therefore, when we are breeding, we should pay attention to the reasonable choice of breeding methods. That's all for today's introduction. This article is for reference only. I hope it can help you all.
