Problems solved by technology

[0006] However, potato black mole is difficult to control as a soil-borne disease, and the existing technology still lacks effective methods to control the spread and development of the disease
In addition, the frequent use of chemical agents will also lead to the emergence of drug resistance, and at the same time bring problems such as pesticide residues and environmental pollution.

preparation example 1

[0069] This preparation example provides a kind of seaweed extract, and its preparation method is as follows:

[0070] (1) Dry the Sargassum algae at 60°C, and after cooling, crush it to a powder with a particle size of 0.1 mm;

[0071] (2) Mix the powder and water into the fermenter at a mass ratio of 1:20 as the fermentation substrate;

[0072] (3) heating the fermenter added with the fermentation substrate to 115 degrees, after sterilizing for 30 minutes, cooling;

[0073] (4) Add 30 billion / g yeast strains to the cooled fermentation substrate, and the addition ratio is 1:1000;

[0074] (5) After the strains are added, the temperature of the fermentation system is controlled at 30°C, and the fermentation is carried out for 36 hours;

[0075] (6) Filtrate after the fermentation is completed, and use the filtrate as the raw material of the seaweed extract after passing the test.

preparation example 2

[0077] This preparation example provides a kind of seaweed extract, and its preparation method is as follows:

[0078] (1) Dry Ascophyllum nodosum at 65°C, after cooling, crush it to a powder with a particle size of 0.15 mm;

[0079] (2) Mix the powder and water into the fermenter at a mass ratio of 1:25 as the fermentation substrate;

[0080] (3) heating the fermenter added with the fermentation substrate to 120 degrees, after sterilizing for 30 minutes, cooling;

[0081] (4) Add 30 billion / g yeast strains to the cooled fermentation substrate, and the addition ratio is 1:1000;

[0082] (5) After the strains are added, the temperature of the fermentation system is controlled at 30°C, and the fermentation is carried out for 36 hours;

[0083] (6) Filtrate after the fermentation is completed, and use the filtrate as the raw material of the seaweed extract after passing the test.

preparation example 3

[0085] This preparation example provides a kind of seaweed extract, and its preparation method is as follows:

[0086] (1) Dry the macroalgae at 55°C, after cooling, crush it to a powder with a particle size of 0.08 mm;

[0087] (2) Mix the powder and water into the fermenter at a mass ratio of 1:15 as the fermentation substrate;

[0088] (3) heating the fermenter added with the fermentation substrate to 110 degrees, after sterilizing for 35 minutes, cooling;

[0089] (4) Add 30 billion / g yeast strains to the cooled fermentation substrate, and the addition ratio is 1:1000;

[0090] (5) After the strains are added, the temperature of the fermentation system is controlled at 30°C, and the fermentation is carried out for 36 hours;

[0091] (6) Filtrate after the fermentation is completed, and use the filtrate as the raw material of the seaweed extract after passing the test.

Abstract

The invention relates to a composition for preventing and treating potato black scurf as well as a preparation method and application thereof. The composition for preventing and treating potato black scurf is prepared from the following components in parts by weight: 0.5 to 10 parts of thyme oil, 0.1 to 0.5 part of eugenol, 5 to 15 parts of nitrogen element, 0.1 to 0.8 part of trace element, 15 to 25 parts of seaweed extracting solution and 5 to 10 parts of emulsifier. The thyme oil, the eugenol, the nitrogen element, the trace elements and the seaweed extract in a specific weight ratio are creatively matched for use, and the composition does not contain any chemical agent, does not enable potatoes to generate drug resistance, can remarkably prevent and control the development of potato black scurf, reduces the incidence rate of the black scurf, and has a good application prospect. The yield of the potatoes can be effectively increased, and the method has very strong practical significance.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a composition for preventing and treating potato black mole and its preparation method and application, in particular to a composition for preventing and treating potato black mole and can significantly increase potato yield, its preparation method and application. Background technique [0002] Potato has the advantages of high yield, good taste, rich nutrition, strong adaptability, etc. It is an important food and economic crop in my country. In recent years, with the improvement of planting efficiency and the continuous expansion of the area, problems such as repeated cropping in potato planting areas and the use of diseased seed potatoes for sowing have led to an increase in the incidence of potato soil-borne diseases in my country year by year. [0003] Potato black mole is a soil-borne fungal disease caused by Rhizoctonia solani. It is reported that the incidence of pota...
