Lychee-seed-containing salt/alkali-resistant composition and preparation method thereof

Abstract

The invention provides a lychee-seed-containing salt / alkali-resistant composition. The invention is characterized in that the raw materials of the composition comprise lychee seeds. The invention also provides a preparation method of the lychee-seed-containing salt / alkali-resistant composition. The method comprises the process of slurry preparation by fermentation. The slurry preparation process comprises the following steps: proportionally mixing composition raw materials Enteromorpha powder, wheat flour, bean sprout juice, goat bone soup and a maltose solution, putting the mixture in a container, and carrying out sealed storage treatment for 35-38 days at 26-29 DEG C, wherein ventilation is carried out every 4-6 days in the storage process; and after the sealed storage is finished, adding Chinese yam powder which is 1.5-2 times of the wheat flour, and fermenting at 31-33 DEG C for 7-9 days. After the salt / alkali-resistant composition is mixed in the saline-alkali soil and used for ploughing, the organic matter content in the saline-alkali soil is enhanced, the pH value of the soil is greatly lowered, the bulk density of soil is lowered, and the soil porosity is enhanced.

Description

technical field [0001] The invention relates to a saline-alkali anti-alkali composition and a preparation method thereof, in particular to a saline-alkali anti-alkali composition containing litchi kernels and a preparation method thereof. Background technique [0002] The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive or have poor growth quality. [0003] 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 cultivation of crops. Therefore, if mung beans are planted in saline-alkali lan...

AI Technical Summary

Problems solved by technology

[0003] 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 mung beans are planted in saline-alkali land, the yield of mung beans will be low, the quality of mung beans will be poor, the nutrients in the mung beans will be deficient, the content of vitamin A, carotene, and potassium will be low, and the mung beans will grow immediately. Blight, leaf spot, ring spot and other problems

[0004] In view of existing problems, many people choose to use chemical fertilizers and pesticides in large quantities to plant mung beans 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 mung beans. 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.
