Problems solved by technology

Biocontrol bacteria have a certain effect on the control of konjac soft rot, but there are also some shortcomings: such as stability problems, most of the biocontrol bacteria are live bacterial preparations, which are affected by environmental conditions such as soil pH, fertility, temperature and humidity, and light in the field. , it is difficult to achieve the expected control effect. In addition, the bio-control bacteria are easily affected by other microorganisms in the field, and it is difficult to become the dominant bacterial group, and it is difficult to colonize, and the control effect will be greatly reduced.
[0005] Although many traditional Chinese medicine fungicides have been applied to the field of biopesticides, such as fungicides containing rhubarb extract and their compositions (ZL02123720.4), these traditional Chinese medicine fungicides are not very specific, which affects their use on konjac soft. The killing effect of pathogenic bacteria of rot, if the traditional Chinese medicine fungicide is to be applied to the prevention and treatment of konjac soft rot, it is necessary to find a good inhibitory and killing effect on the pathogenic bacteria of konjac soft rot from many traditional Chinese medicines with bactericidal effect. Only by prescribing the right medicine and its active ingredients, combined with high-efficiency and low-toxic chemical agents, and adopting the method of "combining traditional Chinese and Western medicine" to treat both symptoms and root causes, can the control effect be effectively improved. However, research in this area has not been reported yet, so there is no research on it. Prevention and control of konjac soft rot. Products with high efficiency control are used in konjac planting and production

Embodiment 1

[0024] As a preferred embodiment of the application, this embodiment discloses:

[0025] A preparation method of using Scutellaria baicalensis to prepare medicines for preventing and treating konjac soft rot. Scutellaria baicalensis is dried in the sun, fully pulverized through a 300-mesh sieve, 100 g of crushed scutellaria baicalensis powder is taken, 500 ml of 80% ethanol is added, and 150 r / Shake at a constant temperature for 48 hours at a speed of 1 min. After the shaking at a constant temperature, suction filtration is performed. The filtrate is rotary evaporated to 150 ml at 50°C to obtain an alcohol extract of Scutellaria baicalensis, and the dregs of Scutellaria baicalensis after suction filtration are naturally sun-dried.

Embodiment 2

[0027] As a preferred embodiment of the application, this embodiment discloses:

[0028] A method for preparing a medicine for preventing and treating konjac soft rot by using Scutellaria baicalensis, drying Scutellaria baicalensis in the sun, fully pulverizing it through a 250-mesh sieve, taking 100g of crushed scutellaria baicalensis powder, adding 700ml of 80% ethanol, and shaking at a constant temperature at 35°C After 50 hours of constant temperature shaking, suction filtration was carried out, and the suction filtrate was rotary evaporated to 200ml at 60°C to obtain an alcohol extract of Scutellaria baicalensis, and the residues of Scutellaria baicalensis after suction filtration were naturally sun-dried. The oscillation speed of the constant temperature oscillation is 150r / min. The ethanol extract of Scutellaria baicalensis obtained after evaporation is stored at a low temperature at a temperature of 5°C.

Embodiment 3

[0030] As a preferred embodiment of the application, this embodiment discloses:

[0031]A method for preparing a medicine for preventing and treating konjac soft rot by using Scutellaria baicalensis, drying Scutellaria baicalensis in the sun, fully pulverizing it through a 270-mesh sieve, taking 100g of crushed scutellaria baicalensis powder, adding 600ml of 80% ethanol, and shaking at a constant temperature at 35°C After 49 hours, after the constant temperature oscillation was completed, suction filtration was carried out, and the suction filtrate was rotary evaporated to 200 ml at 55° C. to obtain the alcohol extract of Scutellaria baicalensis, and the residues of Scutellaria baicalensis after suction filtration were naturally sun-dried. The oscillation speed of the constant temperature oscillation is 150r / min. The ethanol extract of Scutellaria baicalensis obtained after evaporation is stored at a low temperature at a temperature of 5°C.

Abstract

The invention discloses a method for preparing a konjac soft rot control chemical from radix scutellariae and a control method of the konjac soft rot control chemical, and relates to the technical field of plant disease control. The prepared konjac soft rot control chemical adopts alcohol extract of the traditional Chinese medicine radix scutellariae, the traditional Chinese medicine is environmentally friendly and harmless to human beings and livestock. According to the method for controlling the konjac soft rot by the konjac soft rot control chemical prepared from radix scutellariae, comprehensive sterilization components of the traditional Chinese medicine radix scutellariae extract and the quick-acting sterilization components of chemical bactericides are combined and have outstandingcontrol effect on the konjac soft rot. Meanwhile, residual sterilization components and organic matter components of radix scutellariae powder are fully utilized, and have promoting effects on assisting in improving the control effect of soft rot, increasing soil organic matter and improving soil structure.

Description

technical field [0001] The invention relates to the technical field of plant disease prevention and control, and more specifically relates to a method for preparing a medicine for preventing and treating konjac soft rot by using Scutellaria baicalensis and a method for preventing and controlling the disease. Background technique [0002] Konjac (Amorphophallus konjac) is a perennial herbaceous plant of Araceae. It is a rare plant high in glucomannan, and its bulb glucomannan (KGM) content can be as high as about 60% of the dry weight. Konjac glucomannan is the best dietary fiber and the "seventh nutrient element" necessary for the human body. It is one of the first-choice foods for patients with gastrointestinal diseases such as hypertension, obesity, diabetes, constipation, and intestinal cancer. , fine chemicals, biomedicine and other fields have a wide range of applications. Therefore, the economic value of konjac is very high, and it is widely used in the fields of food...
