海藻酸钠寡糖(AOS)对水稻主要病害防治效果初探

The Effect of Alginate Oligosaccharides on the Main Diseases of Rice

为探究海藻酸钠寡糖对水稻主要病害的防治效果,进行田间小区药剂试验。结果表明,海藻酸钠寡糖对水稻主要病害均有一定的防治效果,50×10^(-6)壳寡糖对水稻稻曲病的防治效果最好,海藻酸钠寡糖对水稻稻瘟病及纹枯病防治效果均最好,随着浓度增大,对稻瘟病、稻曲病、纹枯病防效增加。

In order to explore the control effect of alginate oligosaccharides on main rice diseases, Field trials results showed that alginate oligosaccharides had certain control effects on major rice diseases, 50 ×10-6 oligochitosan had the best control effect on rice false smut, alginate oligosaccharide has the best control effect on rice blast and sheath blight,with increased concentration, significant increase in control efficacy against rice blast, rice false smut and sheath blight.
