三种生物制剂对大豆主要农艺性状相关作用的研究

Three biological reagent effect on agronomic characters of soybeans

田间采用经筛选的两种自制复合生物制剂SD-1、SJ-2以及市售的生物制剂绿风95为处理剂,用清水作对照,分别喷施大豆N1215两次。结果表明,与对照相比3种生物制剂对大豆N1215的熟期、株高、荚数、粒重、产量、种子蛋白质含量、含油量及对霜霉病的防治等方面作用不同。其中,自制生物制剂SJ-2在促进大豆产量方面最好,SD-1在提高蛋白质含量和油分含量以及防治霜霉病方面最佳。绿风95对大豆N1215营养生长有一定促进,且产量和含油量略有增加,同时亦降低了蛋白质的含量。

We picked out the complex biological reagent SD-1, SJ-2 and biological reagent bought from market Lv Feng 95 to treat the soybeans N1215 twice in the field, treat soybeans with water as control. The results showed that the three biological reagent play different roles in maturity, plant height, number of pods, seed weight, seed yield, seed protein content, oil content, control of Peronospora manschurica of soybeans N1215. In the three biological reagent, SJ-2 is the best to promote yield of soybeans, SD-1 is the best to promote protein content and oil content and control of Peronospora manschurica moreover, Lv Feng 95 can promote to nutrition development of soybeans and output of soybeans, but reduce the protein content.
