Description
Technical Field
The invention relates to the technical field of rhizoma atractylodis cultivation, in particular to a weeding method for a rhizoma atractylodis planting field.
Background
In the rhizoma atractylodis planting process, the weeding cost for the rhizoma atractylodis field accounts for a large proportion of the field management cost, and the weeding cost directly influences the cultivation cost of the rhizoma atractylodis.
In the prior art, the weeding method of the atractylodes rhizome field is mainly divided into chemical herbicide weeding, mechanical equipment weeding and artificial weeding. The inventor finds that the three weeding methods have the following defects in the process of realizing the invention and creation: firstly, chemical herbicides are used for weeding, the chemical herbicides have certain harm to human bodies, and operators are easy to have the problem of skin contact or oral-nasal inhalation during application, so that poisoning is caused; the herbicide generally aims at specific types of weeds, all weeds in a field cannot be removed, multiple herbicides are used together, the pesticide effects can be influenced mutually, residual weeds can generate pesticide resistance, the pesticide resistance can be increased after iteration, and the next time a larger dose of pesticide is needed for removal and treatment, so that the weeding cost is increased, and the development direction of modern organic Chinese medicinal materials is not met; secondly, when mechanical equipment is adopted for weeding, weeds between planting ridges (furrows) can only be cleared, weeds on the top surfaces of the planting ridges cannot be cleared, the weeding effect is poor, and even if the weeds can be cleared, the risk of damaging stems and leaves of the rhizoma atractylodis exists; thirdly, when the weed is removed by manpower, the hoe is used for removing the weed, only the earth surface part is easily removed in the weeding process, the underground part is not removed, the weeding is not thorough, and the labor cost is high.
Therefore, it is necessary to solve the above-mentioned technical problems.
