Saline-alkali resisting composition containing loofah sponges and preparation method of composition

Abstract

The invention provides a saline-alkali resisting composition containing loofah sponges. The saline-alkali resisting composition is characterized by being prepared from the loofah sponges. The invention further provides a preparation method of the saline-alkali resisting composition containing the loffah sponges. The method is characterized by comprising the fermentation step, wherein after fermentation slurry applying is completed, slurry is fed into a fermentor, the fermentor is sealed, oxygen is introduced, pressure in the fermentor is kept at 0.13-0.14 MPa, the oxygen content is 12.3%-12.5%, and degassing is conducted once every other 60 h to 65 h. After the prepared saline-alkali resisting composition is mixed with saline-alkali land soil, the organic matter content of the soil can be increased to 18.6%-23.5%, the pH value can be decreased to 6.3-7.0, the soil bulk density can be decreased to 1.1-1.3 g / cm<3>, and the soil porosity can be increased to 59%-62%.

Description

technical field [0001] The invention provides a saline-alkali anti-alkali composition and a preparation method thereof, in particular a saline-alkali anti-alkali composition containing loofah 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. In saline-alkali land, because the soil available sulfur content, soil available zinc content, and soil available phosphorus content are low, the soil compaction degree is high, and the air permeability is low, so it brings more problems to the planting of crops. Therefore, planting economic crops, crops, fruits, such as black sesame, etc. in saline-alkali land, there will be problems such as serious lack of nutritional components of the planted black sesame, low yield, and a higher probability of planting diseases of the black sesame. [0003] In view of the existing problems, many people choose to ...

AI Technical Summary

Problems solved by technology

[0003] In view of the existing problems, many people choose to use a large amount of chemical fertilizers and pesticides in the saline-alkali land for crop planting, but the chemical fertilizers in the prior art cannot improve the composition and structure of the saline-alkali soil, and cannot improve the quality and yield of the planted black sesame. At the same time, in order to prevent and control pests and diseases, a large amount of pesticides are used, resulting in too many pesticide residues and the decline of soil quality is becoming more and more serious.
