Problems solved by technology

[0003] Water-retaining agent has become an important agricultural preparation for agricultural and forestry production, and plays an important role in the development of agricultural and forestry production. However, with the excessive and unscientific use of agricultural chemical preparations, it causes soil compaction, damage to the micro-ecological environment, and soil-soil transmission. Diseases are increasing year by year, and crop diseases and insect pests are seriousl

Abstract

The invention provides a biomass water-retaining agent capable of preventing diseases and expelling parasites and a preparation method of the biomass water-retaining agent. The preparation method comprises the following steps: adding acrylic acid into a blender, adjusting the pH value of the system to 5-7 by using sodium hydroxide, conducting cooling to room temperature, adding an aqueous solution of a cross-linking agent, carrying out uniform stirring, sequentially adding fine chitin powder, fine tobacco straw powder, fine bunge pricklyash leaf powder and an initiator into the system, carrying out heating to 50-80 DEG C, conducting polymerizing for 3-5 hours until a polymerization system becomes yellow colloid, then drying, crushing and sieving the colloid, and spraying a microbial liquid preparation to mix the microbial liquid preparation with the colloid. According to the invention, a large amount of the fine biomass chitin powder, the fine tobacco straw powder and the fine bunge pricklyash leaf powder are added, so the waste is turned into the wealth, and the use amount of acrylic acid is reduced on the basis of keeping the performance of a water-retaining agent in the prior art; and chitin contained in the fine chitin powder, nicotine contained in the fine tobacco straw powder and the special smell of bunge pricklyash leaves have the functions of preventing diseases and expelling insects, so the use of chemical pesticides can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural preparations, and relates to a water-retaining agent, in particular to a biomass water-retaining agent for disease prevention and insect repelling and a preparation method thereof. Background technique [0002] Water-retaining agent is a functional polymer material. At present, the main function of water-retaining agent in agricultural and forestry production is: applying it to the roots of plants is equivalent to establishing a miniature reservoir around the rhizosphere of plants, which can absorb a large amount of rainwater and irrigation water. It is released when the soil is short of water, and effectively prevents the leakage and evaporation of water in the soil, improves the utilization rate of water, prevents soil erosion, and achieves the goals of drought resistance, water saving, production increase, and income increase. [0003] Water-retaining agent has become an important agricult...
