Abstract:

At present, the germicidal component of the rice seedling-growth regulator widely used in Heilongjiang province is relatively single, which has made the main pathogenic bacteria in seedling bed appear serious resistance. In order to solve this problem, a comparison test was carried out to study the effects of seedling-growth regulator on rice seedling quality, seedbed disease, number of pathogens in soil and plant biological characteristics in fields in 2018. The results showed that the biological rice seedling-growth regulator had positive effects on the growth of rice seedlings, and had a good control effect on diseases.

摘要:

目前在黑龙江省长期大面积使用的水稻壮秧剂杀菌成分较为单一,已经使苗床主要病原菌出现了严重的抗药性。为解决这一问题,笔者采用大区对比的方法,比较了水稻生物壮秧剂与普通壮秧剂对水稻秧苗素质、苗床病害、土壤中致病菌的数量及本田植株生物学性状等的影响。结果表明,生物壮秧剂对水稻秧苗的生长具有促进作用,并且能较好的控制病害。
