Cultivation techniques of Tripterygium wilfordii

Tripterygium wilfordii is an uncommon and infrequently used Chinese herbal medicine, which is also called vegetable insect medicine and red medicine. Tripterygium wilfordii is a very traditional Chinese medicine, mainly distributed in Taiwan, Fujian, Anhui, Guangxi, Hunan and other places in China, with the role of clearing heat and detoxification, activating blood circulation and dredging collaterals. Today we are mainly to understand the cultivation techniques of Tripterygium wilfordii, let's take a look.

1. Land rectification

Tripterygium wilfordii has the characteristics of warm, humid, cold, frost and wind, so the planting land is generally selected in a relatively mild climate, sheltered area, semi-yin and semi-yang, sufficient rainfall throughout the year, drainage and good permeability of slightly acidic sandy loam or red loam. Fine soil preparation, digging planting holes when soil preparation, generally planting density per mu is about 9,000 plants. When digging planting holes, we should sprinkle enough soil, manure and fine soil for planting.

2. Scientific planting

The propagation methods of Tripterygium wilfordii are seed propagation, cuttage propagation, tissue culture 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 way we plant. Cuttage propagation is generally carried out from the end of November to the end of February of the following year. When cutting seedlings, the row spacing is about 25 cm, and the plant spacing is about 5 cm. The seedlings are inserted obliquely into the seedbed and watered after insertion. During the seedling period, we have to keep the seedbed moist, usually about a month to produce new roots, no more than 50 days at the latest.

3. Cultivation management

After the seedlings cultivated by cuttage survive, they can be transplanted, supplemented and evenly planted. During the growth period of Tripterygium wilfordii, it is generally necessary to carry out three times of intertillage and weeding every year. In the later stage, it is only necessary to carry out weeding once a year. When weeding, it is necessary to pay attention not to deeply remove it so as not to reach its roots. In order to promote the growth of Tripterygium wilfordii, improve the yield and quality of Tripterygium wilfordii, we need to choose fertilizer reasonably according to its fertilizer requirements, but it is best to use organic fertilizer or farm manure for ditch application. Finally, in the growth process of Tripterygium wilfordii, we have to control the growth of its vines, reasonably remove the terminal buds, and promote the growth of lateral branches. When Tripterygium wilfordii blooms, 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 less about Tripterygium wilfordii, we don't know much about its diseases and insect pests, but the most common diseases are anthracnose and root rot, which are also common diseases in most medicinal plants. First, we need to strengthen field management, and second, use chemicals to control, usually using carbendazim and bordeaux mixture to control. There are also timely in its growth process may also appear the harm of leaf roller moth, we can use pyrethroids pest control.

The above is the planting technology of Tripterygium wilfordii that Xiaobian wants 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 to Xiaobian. I believe Xiaobian will bring more wonderful content to you in the later period.
