[目的]为利用氨基寡糖素对作物的诱导提高作物抗病性作为内调及稻瘟酰胺的化学防治效果作为外治来提高防治效果,进行氨基寡糖素和稻瘟酰胺的复配悬浮剂研究。[方法]利用流点测定结合对悬浮剂的稳定性进行筛选确定乳化剂和分散剂的使用;利用模拟春夏秋冬循环试验结合离心试验进行配方稳定性筛选;利用破坏性试验和重复性试验来验证实验结论的可行性。[结果]22%氨基寡糖素·稻瘟酰胺SC优化配方为氨基寡糖素2%,稻瘟酰胺20%,OP-10乳化剂1%,400#2%,500#2%,拉开粉1.2%,NNO分散剂0.6%,D425分散剂0.5%,硅酸镁铝2%,黄原胶0.15%,苯甲酸钠0.5%,丙三醇5%,SAG622消泡剂0.02%,用去离子水补足100%。[结论]对该制剂的性能指标进行测试评价结果显示该制剂的各项目指标符合悬浮剂标准;试验方法有效。
[Objective] The research aimed to improve the disease resistance of crops through the induction of crop with amino-oligosaccharides as the internal control and the chemical control effect of rice blast amide as external treatment to improve the control effect and to carry out the compound suspension of amino-oligosaccharides and rice blast amide Agent research. [Method] The stability of the suspending agent was screened by flow-point assay combined with the use of emulsifier and dispersant. The stability of the formulation was tested by simulating the spring, summer, autumn, winter and winter cycles combined with the centrifugal test. Using the destructive test and the repeatability test Verify the feasibility of experimental conclusion. [Result] The optimal formulation of 22% Aminogalactam and Rice blastamide SC was 2% Amino oligosaccharides, 20% rice blast amide, 1% OP-10 emulsifier, 400 # 2%, 500 # 2% Powder 1.2%, NNO dispersant 0.6%, D425 dispersant 0.5%, magnesium aluminum silicate 2%, xanthan gum 0.15%, sodium benzoate 0.5%, glycerol 5%, SAG622 defoamer 0.02% Water make up 100%. [Conclusion] Test and evaluation of the performance index of the preparation showed that each project index of the preparation conformed to the standard of suspending agent; and the test method was effective.
