Water-saving moisturizing nutrient solution and preparation method thereof

Abstract

The invention discloses a water-saving moisturizing nutrient solution for gardens and belongs to the field of water-retaining agents. The water-savingmoisturizing nutrient solution comprises glycerin, bio-oil, hydroxymethyl cellulose, a microbial agent and water. A preparation method of the water-saving moisturizing nutrient solution comprises the following steps: A, filtering the bio-oil, washing with water, sterilizing at high temperature, dehydrating, and adding the microbial agent (1%) for fermentation treatment; B, adding 50% of water into the bio-oil obtained in the step A, heating, stirring for 2 hours at the temperature of 50-60 DEG C and the stirring speed of 600 r / min, and emulsifying; C, adding the bio-oil in the step B into the glycerol according to the ratio of the glycerol to the bio-oil being 40: 10, stirring for the second time for 30 minutes, standing for 20 minutes, sampling, and inspecting until the liquid is not layered and the liquid level is smooth; D, adding the prepared hydroxymethyl cellulose liquid, mixing according to the ratio of 1: 1, stirring for 30 minutes, standing for 20 minutes, and detecting until no layering or bubbling occurs; and E, determining the pH value of the product, and adjusting with acidic amino acid.

Description

technical field [0001] The invention belongs to the technical field of water-retaining agents, and relates to a water-saving and moisturizing nutrient solution and a preparation method thereof. Background technique [0002] my country is a land country with a vast area, plains, mountains, hills and other terrains. Agricultural water accounts for about 70% of the country's total water consumption, of which irrigation water accounts for more than 90% of the total agricultural water consumption, as high as 360-380 billion cubic meters Rice, saving water and improving water use efficiency is particularly critical, especially in the arid areas of Northwest China, mountains, hills, and sandy land, where water is the lifeblood of the survival and growth of all things. [0003] At present, the country advocates greening barren hills, transforming deserts, turning deserts into fertile fields, turning hills into oases, making full use of limited water, and improving plant survival rate...

Problems solved by technology

The water retaining agents that have been successfully developed in China are mostly divided into three categories: starch, cellulose and acrylic. Starch water retaining agents have high water absorption, but they also have poor salt and alkali resistance and low gel strength. Problems such as short service life

Acrylic water-retaining agent is a high-molecular compound, and its synthetic raw material comes from acrylic acid, a petroleum product. The shortage of petroleum energy and the rise in the price of acrylic acid increase the production cost of sodium polyacrylate water-retaining agent, and under certain conditions, the water-retaining agent of polymer materials The degradation will also produce harmful substances, destroy vegetation, and have adverse effects on human body, plant growth and soil.
