We all know that China is a big country of grain.Peanut is one of the most important crops in China and is one of the most important oil crops in China as well.It an important raw material for food industry as providing the edible oil.In the meantime,peanut has a vital role in the national economy continued rapid development and the development of agricultural structure as Chinese important export products.This study is mainly based on the raw material of natural polymer polysaccharide self-made on adding non-ionic surface active agent, the amount of bentonite, biological regulator, boron modified thirty alkanol, film-forming agent and some trace elements, which are fully mixed.In this paper, the biggest innovation is to add four rare earth elements and four new materials for pest controlling and can be quantified,from which we can get the self-made new type environmental peanut seed coating agent.The main research results are as follows:1?First of all, put the biological repellents, and sodium chloride into the water and make them fully mixed.Then add non-ionic surface active agent, the amount of bentonite, natural polymer polysaccharide, biological regulator, poly sodium phosphate, film-forming agent and some trace elements into it in the 1.5 atmospheric pressure and 60 ?under a pressure condition and make it fully mixed as well.Oscillatory it sufficiently in the electronic oscillator for 3hours and take out then.We can obtain the basic components of homemade peanut seed coating agent, denoted as PA.2?Determine the best amount of medicine of peanut seed coating is 1:45 by observing peanut seedling germination potential and germination rate by 3days, 7days and 15 days of culturing.3?Prepare lanthanum sulfate, cerium sulfate, sulfate and neodymium yttrium sulfate into a concentration of 1 g·L~-1 aqueous solution. Add four different content in different level combination fertilizer(lanthanum, cerium, neodymium, yttrium) aqueous solution into prepared peanut seed coating agent(PA) and fully mixed evenly.Do the orthogonal experiment with the best amount of medicine 1:45 in 3 days, 7 days, 15 days respectively as a unit.Determine the best amount of rare earth element,which we can get a new seed coating agent PB.Compared with available on the commonly used 5 kinds of seed coating agents,PB play the best comprehensive effect with peanut pod number(a), full fruit weight(g), full kernel weight(g), pod plumpness(%) as the reference unit through field experiments.4?Add different levels of four additives(uniconazole, amine ester, neopentyl glycol, violet pigment) into PB, by the inhibition of laboratory experiments, which to determine the optimum adding amount of four kinds of additives in 100 g PB which are as follows: 0.5 g Uniconazole, 1 g amine ester, 1 g diol and 2 g violet pigment, denoted as PC.Then verify the effect of prevention on the peanut root rot, stem rot of peanut, peanut leaf spot and the grub through the field experiment and find it far higher than that of blank control and commonly used 5 kinds of seed coating agents of the effect.It turns out that four kinds of additives have good prevention and treatment of diseases and pests on peanut.5?Add the uniconazole, amine ester, neopentyl glycol, violet pigment according to the optimum adding amount into the water,which denoted as 1#, 2#, 3# and 4#.Determine the changes of peanuts chlorophyll and enzyme by comparing with blank control.The results indicated that the four kinds of additives has a clear role in promoting on the peanut chlorophyll a, b,the activity of superoxide dismutase(POD) and superoxide dismutase(SOD),which can improve the ability of resisting as well.6?The physical indexes of PC were determined by a series of methods and the results showed that the self-made new type environmental peanut seed coating agent met the requirements and the performance standard when set the model Q / WTH38-2010 as a reference standard.Then use PC and commonly used 5 kinds of seed coating agents to coat the peanut seeds,setting blank control.Effects of PC was significantly higher than that of other seed coating agents when set peanut protein,fatty acid content,soluble sugar content before the filling stage as the index,which showed that PC had good market prospects.7?Through the analysis, the environmental protection performance of PC can be obtained mainly in 2 aspects: 1. The ingredients of PC are basically non-toxic, and are easy to decompose and low residue, and are harmless to soil and human body.It has inhibitory effect on bacteria and repellent to pests instead of killing pests for maintaining the balance of the food chain.So PC belongs to the new environment-friendly material and has good prospects for development.
