The Insect Polysaccharide Increases The Resistance To The Soybean To Press The Growth Effect And The Mechanism Research

Insects polysaccharide from insect crust are a natural macromolecular polymers that remove behind the acetyl group getting usually that paries draw, which are currently found only bring positivecharge of the animals cellulose in the natural world- containing amino polysaccharide ofhigh-molecular compound. Because of its molecular structure of the floating amine greatly enhance the response reactive, this determines it from the textile, papcrmaking to food, the environment, medicine, agriculture, forestry, light industry, bioengineering, and other areas have broad applications. Currently insects polysaccharide made in the field of agriculture due to their ability to promote stem roots ,regulate the growth of crop, increase the resisting of the crop, improve advantages such as the output of the crop ,etc. and is accepted extensively by people. At the same time, because of its use is limited in quantity, the results obviously, do not cause environmental pollution, providing drug-free, can be low cost and microbial decomposition of the characteristics of sustainable development in agriculture, with attractive prospects.This experiment was the first to systematically study different concentrations and different degrees of insects delinking acetyl polysaccharide processing of soybean seed growth, physiological characteristics, improve sexual and production impact. Test results show that:1. Insect polysaccharide processing soybean seeds, can seed sprout tendency , fresh and serious and root have facilitation to soybean, and in insects polysaccharide delinking acetyl degrees to 90.7%, consumption at the 80mg each seed in insect, tendency and root are long respectively 15.32% , 55.58% higher than contrast to sprout.2. Insect polysaccharide processing soybean seed, soybean seedling stage to the main agronomic characteristics, such as : the plant is fresh and heavy, dry heavy, and root nodule are counted , dry weight of the root nodule, dry weight of the root and stem length have a significant effect, and there are obvious effects of concentration. Soybean root nodule of plant in which several insect polysaccharide delinking acetyl degrees for 90.7%, consumption of 80mg per kg seeds, 34.55% higher than the comparable contrast.3. Insect many candy deal with soybean seed with obvious reduction emergence of aphid, eat to soybean heart danger that worm lead to the fact have certain prevention and cure results too , and can improve the soybean output notably. When consumption is in per kilogram of seed 50mg insect's many candies, middle part and underpart of the field soybean plant, the emergence amount of the aphid is separately lower by 62.7% , 54.6% than contrast, can reach the extremely prominent level (P<0.01); And rate of pod eaten and worm eat rate to be respectively low to produce 32.04% - 15.32% than contrast, can achieve significant levels (P<0.05).Biological polysaccharide promote crop grow function mechanism has been researching focus both at home and abroad in recent years.this experiment study the effect of insect polysaccharide on α-amylase activity of the burgeoned soybean seeds, the chlorophyll of soybean leaves, solubility protein...
