Problems solved by technology

Most of the products currently used in silkworm breeding are silkworm feed, and the added substances are amino acids, vitamins, antibacterial agents and other substances. There has always been a problem of low leaf silk conversion rate (about 10%). The loss of silkworm cocoons is more than 10%, so how to improve the conversion rate of leaf silk and reduce the incidence of silkworm disease is an important issue in sericulture production

Abstract

The invention discloses lipase wettable powder and application thereof to sericulture. The wettable powder comprises the following raw materials in percentage by mass: 75-85% of lipase raw powder, 5-12% of a wetting agent, 5-12% of a dispersing agent, 1-3% of a stabilizer and 1-3% of a protecting agent. The lipase wettable powder disclosed by the invention can be applied to sericulture, and has the functions or promoting silkworm growth and development, improving disease resistance of silkworms and increasing the yield of silkworm cocoons. The lipase wettable powder disclosed by the invention is diluted with water in a ratio and is sprayed to oak trees, leaves of mulberry trees and the like, or leaves are directly soaked in the diluted lipase wettable powder and are supplied to tussahs, silkworms and the like. The preparation method of the lipase wettable powder disclosed by the invention has the characteristics of being simple in process, low in cost, easy in industrial production and the like, and the preparation has the advantages of being safe and non-toxic to environments, people and livestock, free of residue, simple and convenient to use, remarkable in yield increase effect, easy to popularize and apply and the like.

Description

technical field [0001] The invention relates to a lipase wettable powder and its application in sericulture. Background technique [0002] Lipase (Lipase, EC3.1.1.3), that is, triacylglycerol acyl hydrolase, is a class of enzymes that can catalyze the hydrolysis of long-chain fatty acid glycerides, and can also catalyze the reverse reaction of this reaction—esterification reaction. Lipase has an important physiological function in the living body. Exogenous fat needs to be digested and decomposed by lipase before it can pass through the cell membrane. Lipase is also indispensable for the storage and use of fat in the body. Lipase also participates in intracellular lipid metabolism. The monoacylglycerol, fatty acid and glycerol produced by the decomposition of triacylglycerol by lipase are not only used as energy sources for organisms, but also precursors for the synthesis of phospholipids, sphingolipids and other lipids with important physiological functions. Lipase is not ...
