Green prevention and control method for coptis field weeds based on weeding cloth

Abstract

The invention discloses a green prevention and control method for weeds in a coptis field based on weeding cloth. Coptis chinensis has a high medicinal value, after the coptis chinensis is transplanted, weeds easily grow on a coptis chinensis field, the cost of manually pulling out the weeds is high, although the effect is fast and the cost is low when pesticides are used for preventing and removing the weeds, the coptis chinensis is easily damaged by the pesticides, the quality of the coptis chinensis is influenced, and meanwhile, pesticide residues in the coptis chinensis may cause adverse effects on human health. The weeding cloth is a black chemical fiber braided fabric made of polyethylene, and has the advantages of wear resistance, aging resistance and the like. The weeding cloth not only has the functions of heat preservation and moisture preservation of the mulching film, but also can effectively prevent and remove weeds. The weed control principle is the same as that of a black plastic film, and the black weeding cloth can effectively prevent sunlight from penetrating, so that the growth of weeds is inhibited. According to the method, through a series of processes of soil preparation, weeding cloth covering, weeding cloth punching, coptis chinensis transplanting and fertilizer airing and spreading, control of weeds in the coptis chinensis field is achieved, and meanwhile the method is safe to the environment.

Description

Technical Field

[0001] The invention relates to the technical field of weed control, in particular to a method for preventing and controlling weeds in a coptis chinensis field, and in particular to a green prevention and control method for weeds in a coptis chinensis field based on a weed control cloth. Background Art

[0002] Weeds in the field of Coptis chinensis are serious. Some people mainly use chemical pesticides to control weeds, but this causes pesticide residues in the field of Coptis chinensis, affecting the quality of Coptis chinensis. Manual weeding is more environmentally friendly, but has low efficacy and high cost. Therefore, non-chemical and efficient weed control methods are urgently needed.

[0003] The continuous use of traditional synthetic herbicides leads to various adverse effects, such as weed resistance and pesticide residues. Therefore, there is an urgent need for safer weed control methods as an effective supplement. In addition to the heat preservation and moisture retention functions of mulch, weed control cloth can also effectively prevent weeds. The principle of weed control is the same as that of black plastic film. Black weed control cloth can effectively prevent sunlight from penetrating, thereby inhibiting the growth of weeds.

[0004] Many existing studies have proven that weed cloth has the effect of preventing weeds, but there is currently no report on a method of making holes in the weed cloth in a Coptis chinensis field and transplanting the Coptis chinensis seedlings to the holes, which can prevent weeds without affecting the growth and development of Coptis chinensis. Summary of the invention

[0005] In view of the above shortcomings, the present invention provides a more efficient and safer method for weeding in Coptis chinensis fields, which can not only save the cost of manual weeding, but also effectively avoid the problems of pesticide damage and pesticide residues caused by the use of chemical pesticides. The present invention is achieved by the following technical means:

[0006] A green control method for weeds in Coptis chinensis fields based on weed control cloth, comprising:

[0007] Spread the weed cloth on the tilled Coptis chinensis field, fix it, and use a hole puncher to punch holes on the weed cloth according to the row spacing and plant spacing of Coptis chinensis in the Coptis chinensis field at the same spacing. Then spread the weed cloth on the tilled Coptis chinensis field, and finally transplant the Coptis chinensis seedlings to the place with holes. The weed cloth is a black chemical fiber woven fabric made of polyethylene. When applying fertilizer after 1 month, in order to avoid burning the seedlings, the amount of fertilizer applied is 1 / 3 of the normal amount, and it needs to be exposed to the sun for 2 days before use to remove ammonia, effectively avoid fertilizer damage, and reduce the amount of fertilizer.

[0008] The beneficial effects of the present invention are:

[0009] Using a hole puncher to make holes in the weed cloth is quick and convenient. While reducing the tedious operation of making holes with scissors, it can also accurately control the size of the holes to ensure that the size of the holes can both prevent weeds to the greatest extent and not affect the growth and development of Coptis chinensis. While maximizing cost savings, it can also harvest Coptis chinensis of better quality and increase income. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] Example 1

[0016] A green control method for weeds in Coptis chinensis fields based on weed control cloth

[0017] according to Figure 1-4 The method includes the weed cloth body and the fertilization method. The aperture of the weed cloth is 4-6cm, and the space distance is 20cm. In the specific operation process, according to the row spacing and plant spacing of the coptis chinensis planted in the coptis chinensis field, holes are punched on the weed cloth with a hole puncher according to the same row spacing and plant spacing. Before laying the weed cloth on the coptis chinensis field, it is necessary to remove large clods of soil, lay the weed cloth with holes flat on the coptis chinensis field that has been turned over, fix it, and transplant the coptis chinensis seedlings to the place with holes. One month after the coptis chinensis is transplanted, when applying chemical fertilizers, the fertilizers are mainly concentrated in the holes of the weed cloth. In order to avoid burning the seedlings, the amount of chemical fertilizers applied is 1 / 3 of the conventional amount, and it needs to be exposed to the sun for 2 days before use to remove ammonia; foliar fertilizers suitable for coptis chinensis can also be studied, and fertilization can be applied by spraying the plants. The application technology and operation procedures of weed cloth in coptis chinensis planting are: leveling the ground + laying the cloth + transplanting + fertilization.

[0018] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in the field based on the embodiments of the present invention without creative work belong to the protection scope of the present invention.
