Saline-alkali resistant composition containing smallflower milkwort herb with root and preparation method thereof

Abstract

The invention provides a saline-alkali resistant composition containing smallflower milkwort herb with root. The saline-alkali resistant composition is characterized in that the raw material of the composition comprises the smallflower milkwort herb with root. The invention also provides a preparation method for the saline-alkali resistant composition containing the smallflower milkwort herb with root. The preparation method is characterized by comprising a step of preparation of fermentation slurry, wherein the step of preparation of the fermentation slurry comprises the following steps: subjecting the following raw materials of the composition to mixing according to a proportion in parts: eucheuma muricatum, enteromorpha, sorghum flour, soybean flour, beef broth, a xylose solution and a glucose solution, then placing the mixed raw materials into a water tank, carrying out preserving treatment with the preserving time of 18 to 21 days and the preserving temperature of 30 to 32 DEG C, and carrying out ventilation once every 5 to 6 days in the process of preserving; and after completion of preserving, adding Chinese milk vetch powder with an addition amount being 2 to 3 times of the addition amount of the soybean flour, and carrying out fermentation at the temperature of 31 to 33 DEG C for 7 to 9 days. The saline-alkali resistant composition prepared by using the method provided by the invention can improve the soil available sulfur content, the soil available nitrogen content and the soil available phosphorus content in the saline-alkali soil.

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 golden bull grass 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 celery is planted in saline-alkali land,...

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 celery is planted in saline-alkali land, the yield of celery will be low, the quality of celery will be poor, the nutrients in the planted celery will be deficient, the content of vitamin A, carotene, and vitamin E will be low, and the planted celery will have Problems such as heart rot, spotted blight, and early blight of celery are relatively high

[0004] In view of existing problems, many people choose to use chemical fertilizers and pesticides in large quantities to plant celery in saline-alkali land, but the 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 planting celery. 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.
