Polymerized coated fertilizer for reducing pest and disease damage of strawberries by utilizing modified bamboo fiber

Abstract

The invention relates to a polymerized coated fertilizer for reducing pest and disease damage of strawberries by utilizing modified bamboo fiber. The polymerized coated fertilizer is prepared from the following raw materials in parts by weight: 16-24 parts of ammonium sulfate, 1-2 parts of potassium-magnesium sulfate, 7-9 parts of ammonium bicarbonate, 22-28 parts of extruded soybeans, 0.2-0.4 part of enzyme microorganism, 26-29 parts of rapeseed cakes, 18-24 parts of brewer grain, 6-8 parts of molasses, 15-19 parts of potassium sulfate, 17-23 parts of phosphorus pentaoxide, 20-25 parts of dry duck manure, 12-14 parts of corn starch, 32-38 parts of dry rabbit manure, 6-9 parts of EM microbial agent, 11-13 parts of modified bamboo fiber, 2-4 parts of polyvinyl alcohol, 3-4 parts of diatomite, 2-3 parts of nanocarbon, 1-2 parts of zinc sulfate, 3-5 parts of itaconic acid, 1-2 parts of dimethyl tin oxide, 0.2-0.4 part of hydroxy-propyl acrylate, 0.6-1.2 parts of sorbitan monostearate, 0.1-0.3 part of ammonium supersulfate, and a proper amount of water. The fertilizer has water retention property, soil is loosened, the soil quality is improved, and the fertilizer has a good role in inhibiting bacteria.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a polymer-wrapped fertilizer which utilizes modified bamboo fibers to reduce strawberry diseases and insect pests and a preparation method thereof. Background technique [0002] Bamboo fiber is a regenerated cellulose fiber made from natural bamboo and processed by special high-tech technology. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability, and at the same time has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. Bamboo fiber has a wide range of raw materials and strong utilization. It is mainly manifested in the short growth period of bamboo, which can be grown in 2-3 years and can be planted for a long time. It is naturally degraded in the soil and has no pollution to the environment af...
