Answer: Zhang Xiaoguang, a consultant from the old Association for Science and Technology in Yangling Demonstration Zone and a professor at Yangling Vocational and Technical College, said that weeding is a major problem in the cultivation of Chinese medicinal materials. Hiring someone to weed is very costly, and after weeding the weeds before, the weeds will continue to grow in the later stages, which is difficult to eliminate. In addition, it is forbidden to spray any herbicides in the medicinal fields, otherwise the medicinal materials will easily cause excessive pesticide residues and no manufacturers will buy them. The following methods are recommended:
1. Despite the high cost of manual weeding, it is still a very effective method.
2. When planting Chinese medicinal materials, the problem of weeding in the field should be considered in advance. You can leave a certain distance between the rows when sowing or planting seedlings, so that you can use the knapsack spinner to remove weeds in the future. When weeding, try to control the mower to hit the medicinal plants.
3. When planting medicinal materials, consider covering black ground cloth or black mulching film between rows, which not only weeds but also protects moisture, but also raises the ground temperature, which is beneficial to the growth of medicinal materials. However, this approach will increase input costs, and growers can compare with the cost of human weeding, which one is more cost-effective to choose.
4. Reasonable dense planting can be carried out when planting Chinese medicinal materials to increase the growth density of the medicinal materials and inhibit the growth of weeds. After a certain stage of growth, the medicinal seedlings can be thinned.
