Weeding method for atractylodes lancea planting field

Abstract

The present invention discloses a weeding method for an atractylodes lancea planting field. The method comprises the steps of arranging a plurality of strip-shaped planting ridges in the atractylodeslancea field, and planting atractylodes lancea on the planting ridges; performing mechanical weeding on the atractylodes lancea field by a weeding machine 5-7 days before seedling emergence of the atractylodes lancea, thereby removing weeds on two sides of the top surface and on two side surfaces of each planting ridge; when the seedling emergence rate of the atractylodes lancea is 50-60%, performing mechanical weeding on the atractylodes lancea field by adopting the weeding machine firstly to remove the weeds on two sides of the top surface and on two side surfaces of each planting ridge, andthen performing artificial weeding to remove weeds around the atractylodes lancea; and when the seedling emergence rate of the atractylodes lancea is 100%, performing mechanical weeding on the atractylodes lancea field by adopting the weeding machine firstly to remove the weeds on two sides of the top surface and on two side surfaces of each planting ridge, and then performing artificial weedingto remove the weeds around the atractylodes lancea. According to the weeding method for the atractylodes lancea planting field provided by the present invention, the use of a chemical agent is avoided, the weeding cost is reduced, the weeding effect is improved, and the requirements of organic Chinese herbal medicines are also met by adopting the method.

Description

technical field [0001] The invention relates to the technical field of herb cultivation, in particular to a method for weeding a herb planting field. Background technique [0002] In the process of planting Atractylodes atractylodis, the cost of weeding in the field of Atractylodes atractylodes accounted for a large proportion of field management costs, and the cost of weeding directly affected the cost of cultivating Atractylodes atractylodes. [0003] In the prior art, the weeding methods in the Cangzhu field are mainly divided into chemical herbicide weeding, mechanical weeding, and manual weeding. The inventor found in the process of realizing the invention that the above three methods of weeding have the following deficiencies: first, for weeding with chemical herbicides, chemical herbicides have certain damage to the human body, and operators are prone to skin contact or oral The problem of nasal inhalation leads to poisoning; and herbicides generally target specific ...

AI Technical Summary

Problems solved by technology

The inventor found in the process of realizing the invention that the above three methods of weeding have the following deficiencies: first, for weeding with chemical herbicides, chemical herbicides have certain damage to the human body, and operators are prone to skin contact or oral The problem of nasal inhalation leads to poisoning; and herbicides generally target specific types of weeds, and cannot remove all weeds in the field. The combined use of multiple herbicides may affect each other's efficacy, and residual weeds will develop resistance. Iteration Afterwards, the drug resistance will increase, resulting in the need for a larger dose of pesticides for weeding next time, which increases the cost of weeding, and does not conform to the development direction of modern organic Chinese medicinal materials; The weeds between the planting ridge (furrow) and the weeds on the top of the planting ridge cannot be removed, and the weeding effect is not good. Even if it can be removed, there is a risk of harming the stems and leaves of Atractylodes atractylodes; third, when weeding manually, use a hoe To remove weeds, it is easy to remove only the surface part during the weeding process, while the underground part is not removed, the weeding is not thorough, and the labor cost is high
