The latest planting method of Yuanhu
Rhizoma Corydalis is not only a perennial herb of Papaveraceae, but also a traditional Chinese medicine in China. The main medicinal part is tuber. The main efficacy of Rhizoma Corydalis is to relieve pain, with the effect of Xin San Wen Tong, Xingxue bitter diarrhea, which is widely distributed in our country. Now the planting area of Yuanhu in China is constantly expanding, but there are many who do not know how to plant it. The following editor brings you the planting method of Yuanhu, let's have a look!
1. Land selection and preparation
The root distribution of Yuanhu is relatively shallow, usually the root distribution will not exceed 20 cm, concentrated in about 15 cm. Therefore, before planting, we should choose a good soil, which is soft, sunny, transparent and fertile. And not too wet, to have a good drainage and irrigation capacity, rich in humus and so on. Do not plant on clay or sandy soil. Crop rotation is appropriate. After selecting a good site, we should do a good job of soil preparation, turn it about 22 centimeters deep, improve the softness of the soil, and then prepare the bed for planting.
2. Planting at the right time
The main propagation method of Rhizoma Corydalis is fast stem propagation, and tubers should choose robust multi-bud tubers which are full and succulent and free from diseases and insect pests. It is generally planted around October every year. When planting, we should pay attention to the planting density and keep the plant row spacing above 10 cm. However, before planting, the tubers should be cut into small segments of about 1.5 centimeters, then put them in sterilized solution, soak them for about 12 minutes, and then fish them out to dry for sowing. The main method of sowing is ditch sowing, and two rows of seeds are placed in each ditch according to the row spacing of every 10 cm.
3. Field management
Field management is very important to the yield of Yuanhu. First of all, we must do a good job of fertilization. In addition to the basic fertilizer should be fully applied before planting, we should also pay attention to the application of wax fertilizer, seedling fertilizer and so on to ensure the nutrition to meet the growth needs of Yuanhu. When fertilizing, it should also be carried out in conjunction with the weeding work of intertillage, which can prevent soil consolidation, improve soil permeability and enhance plant nutrition absorption. Proper weeding can prevent weeds from grabbing the growth and nutrition of Rhizoma Corydalis and concentrate the nutrients on the plant. Finally, it is necessary to reasonably water Yuanhu, under the premise of ensuring that Yuanhu has sufficient water, but also pay attention to do a good job of drainage, especially in rainy days, there is no water in the ditch, otherwise Yuanhu is very easy to rot roots, resulting in a decline in yield.
4. Pest control
Pest control is very important for the growth of Yuanhu. Diseases and insect pests harm different organs of Yuanhu plant, which seriously hinders the growth of Yuanhu plant, and the yield will decline with it. Therefore, in the process of planting, we must do a good job in the prevention and control of diseases and insect pests, strengthen field management, timely watering and fertilization, pay attention to the amount of water, prevent and control the production of waterlogging fertilizer and thus cause diseases and insect pests. The common diseases and insect pests of Yuanhu are downy mildew, Sclerotinia sclerotiorum and so on. When doing pest control, we should also pay attention to the direction and purpose of carrying out.
The above is a brief introduction to the planting method of Yuanhu, the growth ability of Yuanhu is relatively strong, and the planting management is relatively simple. The main thing is to pay attention to the prevention and control of diseases and insect pests, because diseases and insect pests will cause fatal harm to the growth of Yuanhu, so it should not be underestimated. That's all for today's introduction. This article is for reference only. I hope it can help you all.
