Problems solved by technology

[0004] However, although there are many kinds of herbicides on the market, due to the particularity of the growth of Bletilla striata itself, it is very sensitive to the herbicides on the market
Even if the herbicides that are safe for general crops are used, sometimes they will cause phytotoxicity to the plants of Bletilla striata, affecting their healthy growth, and using a herbicide alone can no longer completely effectively control the growth of weeds in the Bletilla striata field

preparation example Construction

[0028] The preparation method of this herbicide special for bletilla striata is:

[0029] Take the active ingredient and the ingredients in the additives in parts by weight, mix them evenly, and pulverize them in a sander for 3-5 hours, and then pulverize them by ultrasonic method for 1-2 hours, add an organic solvent to form a coarse dispersion, and then Heat the coarse dispersion in hot water at 50-60°C in a water bath to aid dissolution until the solution becomes clear and transparent, and the herbicide is obtained.

[0030] The application of a special herbicide for bletilla striata in removing weeds in a bletilla striata field. The herbicide has good weeding effect and has no phytotoxicity to bletilla striata plants, and at the same time, since its active ingredients are mainly natural small molecular compounds, it will not cause pesticide residues and environmental pollution.

[0031] In a preferred embodiment of the present invention, the method of using the herbicide ...

Embodiment 1

[0034] This example provides a special herbicide for Bletilla striata, including active ingredients and adjuvants. The content of the active ingredients accounts for 60% of the total amount of the herbicide. Formic acid and citric acid are used to adjust the pH value of the herbicide to 6.0. Wherein, the active ingredients include 21 parts of jatrorrhizine, 18 parts of palmatine, 7 parts of fenthiazone and 8 parts of flubisulfuron in parts by weight.

[0035] The preparation method of this herbicide special for bletilla striata is:

[0036] Take the active ingredient and the ingredients in the additives in parts by weight, mix them evenly, and pulverize them in a sander for 4 hours, and then pulverize them by ultrasonic method for 1.5 hours, add an organic solvent to form a coarse dispersion, and then mix the coarse dispersion As for the hot water at 55°C, it is heated in a water bath to aid dissolution until the solution becomes clear and transparent, and the herbicide is obt...

Embodiment 2

[0039]This example provides a special herbicide for Bletilla striata, including active ingredients and auxiliaries, the content of active ingredients accounts for 55% of the total amount of the herbicide, and ascorbic acid and tartaric acid are used to adjust the pH value of the herbicide to 6.5. Wherein, the active ingredients include 18 parts of jatrorrhizine, 20 parts of palmatine, 8 parts of fenthiazone and 6 parts of flubisulfuron in parts by weight.

[0040] Auxiliaries include dispersants, wetting agents, thickeners, defoamers and antifreeze agents. Among them, the dispersant is lauryl polyoxyethylene ether and polycarboxylate, and the content of the dispersant is 13% of the total amount of herbicide; the wetting agent is sodium alkylbenzene sulfonate and fatty alcohol polyoxyethylene ether , the content of wetting agent is 8% of the total amount of herbicide. The thickener includes starch, polyvinyl alcohol and magnesium aluminum silicate, and the content of the thick...

Abstract

The invention provides special weedicide for bletilla striata and application of the special weedicide and belongs to the field of plant cultivation. The weedicide is prepared from an effective component and an auxiliary agent, wherein the content of the effective component accounts for 55 percent to 65 percent of the total amount of the weedicide and the pH (Potential of Hydrogen) value of the weedicide is 5.5 to 6.5; the effective component is prepared from the following components in parts by weight: 18 to 24 parts of jatrorrhizine, 15 to 20 parts of palmatine, 6 to 8 parts of benzothiazooxadiazon, and 6 to 8 parts of flucetosulfuron. The weedicide provided by the invention can be used for effectively preventing and removing almost annual grass weeds, broadleaf weeds and the like in bletilla striata fields, has the advantages of wide weeding spectrum and good prevention and treatment effect and is relatively moderate to bletilla striata plants; when the weeds are removed, normal growth of the bletilla striata plants is not influenced. When the weedicide is used for removing the weeds of the bletilla striata fields, the weeding effect is good and no phytotoxicity on the bletilla striata plants is caused; meanwhile, active components of the weedicide are natural small molecule compounds so that pesticide residues and environment pollution are not caused.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a special herbicide for bletilla striata and its application. Background technique [0002] Bletilla striata is a perennial herb of the genus Bletilla striata in the family Orchidaceae, and its rhizome is used as medicine. Bletilla striata tastes bitter, sweet, astringent, slightly cold in nature, enters the lung meridian, has the effects of nourishing the lungs, stopping bleeding, reducing swelling, promoting muscle growth, and astringing sores. Poison, ulcer pain, soup fire burns, chapped hands and feet and other diseases. [0003] Bletilla striata has better astringent hemostasis, detumescence and granulation promoting effects. With the continuous deepening of modern pharmacological research, it was found that Bletilla striata has obvious inhibitory effect on Mycobacterium tuberculosis and tumor cells. It has been found clinically that Bletilla striata has a good curative e...
