Description
Technical Field
The invention belongs to the technical field of herbicides, and particularly relates to a green herbicide and a using method thereof.
Background
The weed control is one of the important farming in tea gardens, most of chemical herbicides are toxic and harmful chemical substances, so that the chemical herbicides can also cause damage to crops during weeding, and meanwhile, the potential safety hazard of tea food exists, so that the chemical herbicides are gradually forbidden in the tea gardens. After the chemical herbicide is forbidden, the tea garden mostly adopts manual weeding, but with the aging of labor force and the continuous shortage of market supply in China, the weed control problem in the tea garden becomes more and more serious. Although a plurality of weeding methods exist, the problems of low efficiency, narrow weeding spectrum, poor effect, high cost and potential pollution exist, and the conventional tea garden generally adopts a mode of combining manual weeding with mechanical mowing, so that the labor intensity is high and the working efficiency is low. Therefore, the weeding technology in the tea garden cannot meet the requirement. For this reason, the development of pollution-free, residue-free and efficient green weeding technology for tea gardens is urgent.
Disclosure of Invention
In order to overcome the defects of the prior art, the technical problems to be solved by the invention are as follows: provides a green herbicide with safety, high work efficiency and good control effect.
In order to solve the technical problems, the invention adopts the technical scheme that: a green herbicide comprises carbon powder and vegetable oil.
Wherein the mass ratio of the carbon powder to the vegetable oil is 1: 1-2.
The green herbicide is applied before the weeds do not bloom.
The invention has the beneficial effects that: the herbicide provided by the invention can be adhered to weeds and the soil surface around the weeds after carbon powder and vegetable oil are mixed into a carbon powder oiling agent, the carbon powder oiling agent is adhered to the weeds to block air holes and hinder photosynthesis and respiration of the weeds, so that enough organic matters cannot be formed for self growth of the weeds, weeds are killed, and the purpose of preventing and removing the weeds is achieved. The green herbicide can be sprayed, the operation efficiency is high, the labor and time consumed by artificial weeding can be greatly reduced, the herbicide can be used as a spray after being properly improved, the herbicide has the advantages of multi-pipe and combined action, quick response, rapid weed growth inhibition, belongs to the physical weeding category, has no host selectivity, completely covers all weeds by a weeding spectrum, is effective to all the weeds, has natural sources of raw materials, is easy to degrade, has no biological risk and ecological risk, is pollution-free, green and safe, and has a certain effect of improving soil.
Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description will be given with reference to the embodiments.
The most key concept of the invention is as follows: the tea garden weed management is carried out by utilizing carbon powder and vegetable oil according to the principle of physical weeding.
The invention provides a green herbicide, which comprises carbon powder and vegetable oil.
From the above description, the beneficial effects of the present invention are: the herbicide provided by the invention can be adhered to weeds and the soil surface around the weeds after carbon powder and vegetable oil are mixed into a carbon powder oiling agent, the carbon powder oiling agent is adhered to the weeds to block air holes and hinder photosynthesis and respiration of the weeds, so that enough organic matters cannot be formed for self growth of the weeds, weeds are killed, and the purpose of preventing and removing the weeds is achieved. The green herbicide can be sprayed, the operation efficiency is high, the labor and time consumed by artificial weeding can be greatly reduced, the herbicide can be used as a spray after being properly improved, the herbicide has the advantages of multi-pipe and combined action, quick response, rapid weed growth inhibition, belongs to the physical weeding category, has no host selectivity, completely covers all weeds by a weeding spectrum, is effective to all the weeds, has natural sources of raw materials, is easy to degrade, has no biological risk and ecological risk, is pollution-free, green and safe, and has a certain effect of improving soil. The green herbicide provided by the invention is mainly suitable for being used in tea gardens and can also be popularized and tried in other agricultural planting areas such as orchards, vegetable gardens and the like.
Further, the mass ratio of the carbon powder to the vegetable oil is 1: 1-2.
As can be seen from the above description, too much powdered carbon will reduce the amount of powdered carbon adhering to the leaves, and too much vegetable oil will reduce the amount of powdered carbon adhering to the leaves, and the above ratio is the optimum ratio.
Further, the particle size of the carbon powder is larger than 32 meshes.
As can be seen from the above description, the carbon powder with too large particle size has increased gravity and is not easy to adhere to the weed leaves, while the carbon powder with too small particle size increases the cost and has no significant effect on the weeding effect.
Further, the vegetable oil is one or more of cottonseed oil, palm oil, rapeseed oil, rice bran oil, sunflower seed oil and peanut oil.
The green herbicide is applied before the weeds do not bloom.
As is apparent from the above description, the time for controlling weeds using the green herbicide of the present invention should be before the weeds do not affect tea plants and before the weeds do not flower.
Example 1:
the charcoal powder (particle size of 40 meshes) and the peanut oil in the mass ratio of 1:1 are mixed to obtain a green herbicide, the green herbicide is used for a spraying weed control test by a paint sprayer in a 7-17-7-17-2019-1-month-old Fuyun No. 6 variety 3-age tea garden after artificial weeding in a Fuan tea area, a thin layer of the green herbicide is uniformly sprayed on weeds and the surrounding soil surface of the weeds, investigation is carried out after 14 days, the biomass of open-air weeds is reduced by 94%, the population coverage and the average height are unchanged, and the phenomena of withering and death of young leaves of the weeds begin to appear.
Example 2:
mixing charcoal powder (with a particle size of 45 meshes) and cottonseed oil according to a mass ratio of 1:2 to obtain a green herbicide, performing a spraying weed control test on 3-age young tea gardens of a golden kwan variety 1 month after artificial weeding in a Fuan tea area by using the green herbicide by using a paint sprayer within 7 months and 17 days in 2019, uniformly spraying a thin layer of the green herbicide on weeds and surrounding soil surfaces of the weeds, investigating after 14 days, wherein the biomass of open-land weeds is reduced by 97%, the population coverage and the average height are unchanged, and the phenomena of withering and death of young leaves of the young weeds begin to appear.
Example 3:
mixing charcoal powder (with the particle size of 35 meshes) and palm oil according to the mass ratio of 1:1.5 to obtain a green herbicide, performing a spraying weed control test on 3-age young tea gardens of narcissus species 1 month after artificial weeding in a Fuan tea area by using the green herbicide by using a paint sprayer in 7-17 days in 2019, uniformly spraying a thin layer of the green herbicide on weeds and surrounding soil surfaces of the weeds, investigating after 14 days, wherein the biomass of open-air weeds is reduced by 95%, the population coverage and the average height are unchanged, and the phenomena of withering and death of young leaves of the young weeds begin to appear.
The species symptoms and the open space weed unit biomass (g/m) of the main weeds in the tea gardens of examples 1 to 32) The statistics are carried out, and the results are shown in Table 1 (weed symptom expression in 14 days after weeding) and Table 2 (weed biomass (g/m) in 14 sky land after weeding)2) Shown in (c).
