example 1

[0024] Weigh fresh ripe grapes, wash them once with clear water, put them into a tissue grinder after drying for 20 minutes, and pulverize them for 20 minutes to obtain grape pulp, put the grape pulp of 4 / 5 of the volume of the fermenter into the fermenter, seal the mouth of the tank, Sealed fermentation at a temperature of 26°C for 15 days. After the fermentation, filter and separate to obtain the fermentation filtrate; weigh the sepiolite and put it in a ball mill to grind for 1 hour and pass through a 200-mesh sieve to collect the sieved powder. The fermentation filtrate was mixed according to the mass ratio of 1:3, put into an ultrasonic oscillator, treated with ultrasonic oscillation at a power of 200W for 30 minutes, and filtered to obtain the filter residue, which was pre-modified sepiolite powder; After mixing at a ratio of 1:1:5, crush it into a mixed slurry with a pulverizer, mix the mixed slurry and yeast powder at a mass ratio of 10:1, and leave it to ferment at 35°...

Abstract

The invention relates to the technical field of soil remediation and particularly relates to a preparation method of a soil-loosening humectant. The preparation method comprises the steps of firstly carrying out grape fermentation so as to prepare grape fermentation liquid rich in alcohol, soaking sepiolite powder by virtue of the grape fermentation liquid, carrying out hydroxylation modificationon the surface of the sepiolite powder by virtue of alcohol so as to increase the number of hydroxide radicals on the surface of the sepiolite, extracting supernatant rich in amino acids from fermented bean curds and soybeans which are rich in amino acids, carrying out blending fermentation modification on the supernatant and the hydroxylation-modified sepiolite, introducing amino and hydroxide radicals to the sepiolite by virtue of microorganisms so as to obtain modified sepiolite, and grafting the modified sepiolite to acrylic acid, so as to finally obtain the soil-loosening humectant. According to the soil-loosening humectant, the sepiolite has the property of swelling after water absorption, and the soil-loosening humectant is applied to soil and is capable of swelling after the waterabsorption and opening soil so as to realize a soil loosening effect, so that the hardening of the soil is avoided, water molecules can relatively easily enter the soil so as to improve the moisture absorption of the humectants, and the soil-loosening humectant has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a preparation method of a soil loosening and moisturizing agent. Background technique [0002] The area of ​​arid and semi-arid areas in my country accounts for 47% of the total land area. Most areas cannot be irrigated due to water shortages or restrictions on irrigation conditions. Natural precipitation has become the main water source for agricultural production in these areas. However, in recent years, precipitation in these areas has generally decreased, and how to achieve effective maintenance and efficient use of natural precipitation has become the key to the sustainable development of agriculture in these areas. [0003] Agricultural humectant is a new type of polymer material with super water absorption and water retention properties. It has a significant effect on inhibiting soil water loss and can well alleviate the impact of less precipitation on agricultural ...
