The field management method of Yuanzhi

Polygala tenuifolia is not only a perennial herb, but also a widely used traditional Chinese medicine. Polygala has a variety of effects, such as calming the mind and removing phlegm, promoting intelligence and detumescence, and its planting area in our country is very large. And now more and more people are planting Yuanzhi, and the most important thing to plant Yuanzhi is to do a good job of management. So how to manage planting Yuanzhi? The following editor has brought you Yuanzhi's field management technology, let's have a look!

1. Replenish seedlings with intermediate seedlings

The seeds of Polygala tenuifolia are relatively small, and the resistance of soil-breaking seedlings is also very weak, so the seedling management is very important. We should often check the growth of seedlings, and when we find that there is a lack of seedlings, we must make up the seedlings with the same growth in time. Then when the seedlings grow to about 3 cm, in order to let the seedlings have sufficient growth space, it is necessary to do a good job of inter-seedling work, retain strong seedlings, and improve the nutritional area. When you grow 3 cm and reach 6 cm, do a good job of fixing the seedlings. According to the sowing method to control the plant distance, for example, if it is direct seeding, the plant distance is kept at about 12 cm, while the seedling transplanting can control the plant distance at about 3 cm.

2. Ploughing and weeding

As I just said, the growth ability of Polygala seedlings is relatively weak, and the growth rate is also very slow. Therefore, we must do a good job of ploughing during the growing period. When ploughing, we should pay attention to the depth, mainly shallow, not too deep, so as to avoid hurting the roots of the seedlings and get rid of the weeds. In a year, the seedlings of Polygala tenuifolia have poor resistance, so it is necessary to weed more. Keep the soil surface relaxed and have a certain water content in the lower layer to promote root growth in the countryside. However, weeds should not be completely removed. An appropriate amount of weeds can alleviate the impact of heavy rain, reduce the burden for seedlings, and improve the ability of soil moisture conservation.

3. Water and fertilizer management

Water and fertilizer management is also an indispensable management work in planting Polygala tenuifolia. Especially in the seedling stage, we must pay attention to more watering, the lack of water will lead to the lack of water and death of the seedlings. After fixing the seedlings, it is necessary to control the amount of water and improve the cold resistance of the plants, and then pay attention to drainage in the rainy season to avoid waterlogging and rotting roots. When topdressing, the fertilizer should be based on phosphorus and potassium fertilizer, which can enhance the disease resistance of the plant, and the yield will increase obviously. In the flower and fruit stage, stem and leaf growth period and turning green, there is a great demand for nutrition, so we must do a good job of topdressing according to the growth stage of Polygala.

4. Covering grass and picking buds

Yuanzhi annual seedlings after weeding or two-year-old seedlings after topdressing. We should properly cover some straw, wheat bran and other forage, continuous coverage for about 3 years, do not need to turn. This can effectively improve the organic matter in the soil, improve the soil, and inhibit the growth of weeds. And in order to promote the growth of Polygala root and improve the accumulation of nutrition. When we are in the early stage of bud formation, we should remove those buds that do not leave seeds, and the time should be chosen in a sunny day, which can improve the speed of wound healing.

The above is a brief introduction of Yuanzhi field management methods. The management of Yuanzhi is very important, we must pay more attention to it!
