Rhizoma dioscoreae extract containing salt-alkali-resistant composition and preparation method therefor

Abstract

The invention provides a rhizoma dioscoreae extract containing salt-alkali-resistant composition. The rhizoma dioscoreae extract containing salt-alkali-resistant composition is characterized in that raw materials of the composition contain a rhizoma dioscoreae extract. The invention further provides a preparation method for the rhizoma dioscoreae extract containing salt-alkali-resistant composition. The preparation method is characterized by comprising the step of preparing fermented slurry, wherein the step of preparing the fermented slurry comprises the steps of mixing the raw materials of the composition, i.e., agar, Gloiopeltis, maize meal, soybean meal, coconut juice and a lactose solution according to a parts ratio so as to prepare slurry, carrying out uniform stirring, then, putting the uniformly-stirred slurry into a vessel, carrying out sealed preservation treatment for 25 to 27 days at the temperature of 32 DEG C to 34 DEG C, and then, carrying out ultraviolet radiation treatment on the mixed material. Through planting allium sativum in saline-alkaline land by using the salt-alkali-resistant composition prepared by the preparation method, the incidence rate of rust disease can be lowered; the incidence rate of allium sativum purpura can be lowered; and the incidence rate of sclerotinia sclerotiorum of allium sativum can be lowered.

Description

technical field [0001] The invention provides a saline-alkali anti-alkali composition and a preparation method thereof, in particular to a saline-alkali anti-alkali composition containing yam extract and a preparation method thereof. Background technique [0002] In saline-alkali land, the soil organic matter content, available nitrogen content, and available phosphorus content are low, the soil compaction degree, pH are high, and the air permeability is low, so it brings more problems to the planting of crops. Therefore, if garlic is planted in saline-alkali land, the yield of the planted garlic will be low, the quality will be poor, the nutrients in the planted garlic will be deficient, the content of vitamin C, carotene, and niacin will be low, and the planted garlic will suffer from rust. , purpura, sclerotia and other problems. [0003] In view of existing problems, many people choose to use chemical fertilizers and pesticides in large quantities to plant garlic in sal...

AI Technical Summary

Problems solved by technology

[0002] In saline-alkali land, the soil organic matter content, available nitrogen content, and available phosphorus content are low, the soil compaction degree, pH are high, and the air permeability is low, so it brings more problems to the planting of crops

Therefore, if garlic is planted in saline-alkali land, the yield of the planted garlic will be low, the quality will be poor, the nutrients in the planted garlic will be deficient, the content of vitamin C, carotene, and niacin will be low, and the planted garlic will suffer from rust. , purple spot disease, high incidence of sclerotia, etc.

[0003] In view of existing problems, many people choose to use chemical fertilizers and pesticides in large quantities to plant garlic in saline-alkali land, but chemical fertilizers in the prior art cannot improve the composition and structure of saline-alkali soil, and cannot improve the quality and nutrient content of planted garlic. At the same time, in order to prevent and control pests and diseases, the pesticide residues are too large and the soil quality is declining.
