The latest course of cultivation techniques of Tripterygium wilfordii

Tripterygium wilfordii is an uncommon and uncommonly used traditional Chinese medicine, and some people call it vegetable insect medicine and red medicine. Tripterygium wilfordii is a very traditional Chinese medicine, which is mainly distributed in Taiwan, Fujian, Anhui, Guangxi, Hunan and other places in China. Today we are mainly here to understand the cultivation techniques of Tripterygium wilfordii. Let's take a look at it.

1. Land rectification and reform

Tripterygium wilfordii has the characteristics of warm, moist, cold-resistant, frost-resistant and wind-resistant, so the planting land is generally selected in the slightly acidic sandy loam or red loam with relatively mild climate, shelter, half-yin and half-yang, adequate rainfall throughout the year, drainage and good permeability. Fine soil preparation, digging planting holes during soil preparation, the general planting density per mu is about 9,000 plants. When digging the planting hole, we should sprinkle enough soil and miscellaneous fertilizer, farm manure mixed fine soil for planting.

2. Scientific planting

The propagation methods of Tripterygium wilfordii include seed propagation, cutting propagation, tissue propagation and wild domestication propagation. Seed propagation is mainly difficult to harvest seeds, generally not often used, and cutting propagation is the most commonly used in planting. Cutting propagation is generally carried out from the end of November to the end of February of the following year. When cutting seedlings are raised, the row spacing is about 25 cm, and the plant spacing is about 5 cm. The seedlings are obliquely inserted into the seedbed, and then watered. During the period of raising seedlings, we should keep the seedbed moist. Generally, new roots can take place in about a month, and no more than 50 days at the latest.

3. Cultivation and management

After the seedlings cultivated by cutting survive, the seedlings can be transferred, replenished and evenly planted. During the growth period of Tripterygium wilfordii, it is generally necessary to carry out intermediate ploughing and weeding three times a year, and in the later stage, weeding only needs to be carried out once a year. Attention should be paid not to deep weeding when weeding, so as not to reach its roots. In order to promote the growth of Tripterygium wilfordii and improve the yield and quality of Tripterygium wilfordii, we need to choose fertilizer reasonably according to its fertilizer demand, but it is best to apply organic fertilizer or farm manure. Finally, in the growth process of Tripterygium wilfordii, we should control the growth of its vines, remove the terminal buds reasonably and promote the growth of lateral branches. When Tripterygium wilfordii blossoms, we need to remove the buds, which can improve the efficiency of nutrient use and promote root growth.

4. Disease and pest control

Because we know little about Tripterygium wilfordii, we do not know much about its diseases and insect pests, but at present the most common diseases are anthracnose and root rot, which are also common diseases in the planting of most medicinal materials. First of all, we need to strengthen field management, and the second is to use chemicals for control, usually using carbendazim and Bordeaux solution. There is also in time in its growth process may also appear the harm of leaf moth, we can use pyrethroid insecticides for control.

The above is the planting technology of Tripterygium wilfordii that the editor would like to introduce to you today. I hope it can help you. At the same time, I also thank you for your long-term support and encouragement. I believe the editor will bring you more wonderful content in the later stage.
