Embodiment 1

[0037] Embodiment 1 A kind of efficient control method of weeds

[0038] 1. Materials and methods

[0039] 1.1 Test material

[0040] The test site was selected at Hengxi Town Base, Jiangning District, Nanjing Institute of Vegetable Science, Jiangsu Province. The trial period is the beginning of August 2017. Cosmos and lime nitrogen (calcium cyanamide) are selected as landscape flower species, provided by Ningxia Darong Industrial Group Co., Ltd., and organic fertilizers are provided by Nantong Huinong Biological Organic Fertilizer Co., Ltd.

[0041] 1.2 Test method

[0042] 1.2.1 Experimental design

[0043] The experiment set up an experimental group and a control group. Experimental group: Choose a period of time in August when the weather is the hottest and the light is the best. figure 1 ); Undecomposed cow dung is applied in the soil by the amount of 1t / mu, and evenly sprinkled with lime nitrogen, used by the amount of 50kg per mu (such as figure 2 ). Plow 2 to ...

Embodiment 2

[0060] Embodiment 2 A kind of efficient control method of weeds

[0061] 1. Materials and methods

[0062] 1.1 Test material

[0063] The test site, test time and test materials are the same as in Example 1. Landscape flower species choose zinnia.

[0064] 1.2 Test method

[0065] 1.2.1 Experimental design

[0066] The experiment set up an experimental group and a control group. Experimental group: choose the hottest period of August in summer and the best sunlight, and first clean up the weeds, residual branches and fallen leaves on the open space; apply 1.5t / mu of undecomposed Chinese medicine residue to the soil, and Spread lime nitrogen evenly, and use it at a rate of 55kg per mu. Plow 2 to 3 times with a plowing depth of 25 to 30 cm to fully mix the soil, organic fertilizers, and lime nitrogen; flood the ground with water until the surface sees clear water, so that the soil water holding capacity of the plot can reach 70%; choose the whole plot The plastic film is ...

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...
