Problems solved by technology

[0002] Weed control is one of the important farming tasks in tea gardens. Most of the chemical herbicides are poisonous and harmful chemicals. While weeding, they will also cause damage to crops. At the same time, there are hidden dangers to tea food safety, so chemical herbicides are widely used in tea gardens. progressively disabled in
After the prohibition of chemical herbicides, tea gardens mostly use manual weeding, but with the aging of my country's labor force and the continuous shortage of market supply, the problem of weed control in tea gardens is becoming more and more serious
Although there are many methods of weeding, there are problems of low efficiency, narrow weeding spectrum, poor effect, high cost, or potential pollution. Considering all aspects, the method of manual weeding combined with mechanical weeding is generally used in tea gardens, which is labor-intensive. , low work efficiency
It can be seen that the tea garden weeding technology can not meet the demand

Embodiment 1

[0020] According to the mass ratio of 1:1 charcoal powder (particle size 40 mesh) and peanut oil mixed to obtain a green herbicide, on July 17, 2019, one month after the artificial weeding in Fu'an tea area, Fuyun 6 variety 3 The young tea garden used the green herbicide and used a paint sprayer for spraying and weed control tests. A thin layer of green herbicide was evenly sprayed on the weeds and the surrounding soil. After 14 days of investigation, the biomass of weeds in the open space was reduced by 94% , The population coverage and average height remained unchanged, and the young shoots and young leaves of weeds began to wither and die.

Embodiment 2

[0022] According to the mass ratio of 1:2 charcoal powder (particle size 45 mesh) and cottonseed oil mixed to obtain a green herbicide, on July 17, 2019, 1 month after artificial weeding in Fuan tea area, Jin Guanyin variety 3 years old Young tea gardens used the green herbicide and used a paint sprayer to spray and control weeds. A thin layer of green herbicide was evenly sprayed on the weeds and the surrounding soil. After 14 days of investigation, the biomass of weeds in the open space was reduced by 97%. The population coverage and average height did not change, and the young shoots and young leaves of weeds began to wither and die.

Embodiment 3

[0024] According to the mass ratio of 1:1.5 charcoal powder (particle size 35 mesh) and palm oil are mixed to obtain a green herbicide. On July 17, 2019, the narcissus variety 3 years old after 1 month of artificial weeding in Fuan tea area The green herbicide was used in the green herbicide and the paint sprayer was used for spraying to control weeds. A thin layer of green herbicide was evenly sprayed on the weeds and the surrounding soil. After 14 days of investigation, the biomass of weeds in the open space was reduced by 95%. The coverage and average height did not change, and the young shoots and leaves of weeds began to wither and die.

[0025] For the type symptoms of the main weeds in the tea garden of Examples 1-3 and the unit biomass of weeds in the open space (g / m 2 ) Statistics, the results are shown in Table 1 (weed symptom performance of 14 days after weeding), Table 2 (weed biomass of 14 days after weeding (g / m 2 )) as shown.

Abstract

The invention discloses an environmentally friendly herbicide and a use method thereof. The environmentally friendly herbicide comprises carbon powder and vegetable oil; and the mass ratio of the carbon powder to the vegetable oil is 1: 1-2. According to the herbicide provided by the invention, the carbon powder and the vegetable oil are mixed, and an obtained mixture can be adhered to weeds and soil surfaces around the weeds; since the vegetable oil is adhered to the weeds and block air holes, so that the photosynthesis and respiration of the weeds are hindered, the weeds cannot form enough organic matters for self-growth, and as a result, the weeds are killed, and the weeds can be prevented and eliminated; when the temperature in summer is high, the carbon powder can further absorb lightand increase the probability that the leaves of the weeds are burnt, so that the weeds can wilt, wither and die faster. The environmentally friendly herbicide completely covers all weeds in weeding spectrum, is made of natural raw materials, easy to degrade, free of biological risks and ecological risks, free of pollution, green and safe, and also has a certain soil improvement effect.

Description

Technical field [0001] The invention belongs to the technical field of herbicides, and specifically relates to a green herbicide and a use method thereof. Background technique [0002] Weed control is one of the important agricultural tasks in tea gardens. Since most of the chemical herbicides are toxic and harmful chemicals, they can also cause damage to crops while weeding. At the same time, there are hidden tea food safety hazards, making chemical herbicides in tea gardens. Gradually disabled. After chemical herbicides were banned, tea gardens were often weeded manually. However, with the aging of our labor force and the continuous shortage of market supply, the problem of weed control in tea gardens has become more and more serious. Although there are many weeding methods, there are problems of low efficiency, narrow weeding spectrum, poor effect, high cost, or potential pollution. From a comprehensive consideration, artificial weeding combined with mechanical mowing are com...
