High-efficiency weed control method

Abstract

The invention discloses a high-efficiency weed control method which comprises the following steps: 1) soil preparation; 2) spreading materials; 3) turning over; 4) irrigating with enough water, namelyperforming broad irrigation until water is seen on the surface; 5) covering the mulching film, namely selecting a whole mulching film to achieve rapid covering after irrigating with enough water, pressing soil blocks at the periphery, and forming a relatively closed environment; 6) closing the film; and 7) uncovering the film, airing, and seeding landscape flower seeds. Compared with the traditional weed control method, the method disclosed by the invention is simple, low in cost and easy to popularize. The organic fertilizer is thoroughly decomposed by utilizing a high temperature, the planting risk is reduced, the soil fertility is increased, the grass seeds are killed, the weeds are effectively controlled, and a good growth environment is provided for subsequent plant growth. Accordingto the method disclosed by the invention, any chemical herbicide is hardly used subsequently, manual weeding is not needed, the input cost is reduced, drug-resistant weeds can be effectively controlled, the drug resistance of the weeds is delayed, and green and sustainable control of the weeds is facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of landscaping, and in particular relates to a high-efficiency control method for weeds. Background technique: [0002] Weeds are a kind of agricultural and forestry pests with persistent hazards. They interfere with the growth of target plants, deteriorate the environment, spread diseases and insect pests, hinder mechanical seeding, and increase input costs. They are one of the important biological factors that endanger the landscaping industry. In recent years, due to the lack of labor force and irrational use of herbicides, the occurrence of malignant weeds in my country has increased, community succession has accelerated, the population of refractory weeds has become prominent, and weed resistance has developed rapidly, increasing the difficulty of sustainable weed management. . There are 1454 species of garden weeds in my country (including subspecies, variants, variants), more than 130 species of seri...

Problems solved by technology

For example, the implementation of the flood and drought rotation system has a good control effect on many weeds that are not tolerant to flooding or drought, but this method is limited in scope and cannot be widely used
