Saline-alkali-resisting composition containing oldenlandia diffusa and preparation method thereof

Abstract

The invention provides a saline-alkali-resisting composition containing oldenlandia diffusa. The saline-alkali-resisting composition is characterized by comprising the oldenlandia diffusa. A preparation method of the saline-alkali-resisting composition is characterized by including preparing spraying slurry, to be more specific, mixing Sarcodia montagneana powder, highland barley flour, decocted sticky rice and glucose liquid according to the proportion, decocting with small fire for 60-66 minutes after boiling, storing the mixed liquid at 30-32 DEG C for 20-25 days in a sealed manner after cooling, ventilating, adding fruit peel during the ventilation, and preserving the temperature of 30-32 DEG C for 6-7 days to obtain the spraying slurry. The cation exchange capacity / water-soluble organic carbon ratio of the prepared saline-alkali-resisting composition is 1.9-2.5, the C / N ratio of the saline-alkali-resisting composition is 0.26-0.44, and the salmonella content of the saline-alkali-resisting composition is 0.2-0.5 / g.

Description

technical field [0001] The invention relates to a saline-alkali-resistant composition and a preparation method thereof, in particular to a saline-alkali-resistant composition containing Hedyotis diffusa 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 corn is planted in saline-alkali land, the yi...

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 corn is planted in saline-alkali land, the yield per mu of planted corn will be low, the content of potassium, carotene, and phosphorus in corn will be low, and the incidence of smut, rust, and rice blast will be prone to problems such as high incidence of corn

[0004] In view of the existing problems, many people choose to use a large amount of chemical fertilizers and pesticides to plant sorghum 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 planted corn. 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.
