Problems solved by technology

Among them, the materials used as binders mainly include yellow mud, corn starch and modified corn starch. While the function is single, the yellow mud has low cohesive force and poor toughness. There are often disadvantages such as germs, and although starch and modified starch have good bonding effects, the preparation process is cumbersome.

Abstract

The invention relates to the field of rice breeding, in particular to a binder for rice breeding and a preparation method thereof, and the binder is prepared from 0.5% sodium carboxymethyl cellulose, guar gum, a graphene oxide solution, glycerol, amino-oligosaccharin and melissyl alcohol. Specifically, the anti-aging agent is prepared from the following raw materials in parts by weight: 20-40 parts of 0.5% sodium carboxymethyl cellulose, 1-2 parts of guar gum, 0.3-0.5 part of a graphene oxide solution, 0.1-0.3 part of glycerol, 1-2 parts of amino-oligosaccharin and 0.5-1 part of melissyl alcohol. The rice seed paper adhesive has excellent adhesive force and toughness, and can remarkably improve the rice emergence rate and the dry matter accumulation of rice seedlings while meeting the requirements of the rice seed paper adhesive.

Description

technical field [0001] The invention relates to the field of rice breeding, in particular to a binder for rice breeding and a preparation method thereof. Background technique [0002] There are a lot of breeding materials in the early generation of rice. In order to prevent sowing confusion, breeders generally use the method of planting paper to raise seedlings. Seedling raising by planting paper refers to the method of raising seedlings after sticking rice seeds on degradable seedling raising film or paper. Among them, the materials used as binders mainly include yellow mud, corn starch and modified corn starch. While the function is single, yellow mud has low cohesive force and poor toughness. There are often disadvantages such as germs in starch, and although starch and modified starch have good bonding effects, the preparation process is cumbersome. Contents of the invention [0003] In order to solve the above problems, the present invention provides a binder for ri...
