不同抗旱剂对水稻生长发育及产量的影响
Effects of Different Polysaccharide Drought-resistant Agent on Growth and Yield of Rice
摘要
Abstract
The effects of spraying different concentration of polysaccharide drought-resistant agent on growth and yield of rice were studied, with indica rice N22, Q you6 and II you838 as materials, at spike differentiation stage of drought stress. The results showed that the effects of different concentration of polysaccharide could increase the yield of rice, the yield of A3 treatment are equal to the control treatment. The contribution of spraying polysaccharide on yield is mainly due to stable effective panicle number per plant, in-crease the number of grains per panicle and seed setting rate, spraying polysaccharide can increase the rice dry matter, maintain the stability of the plant height, higher tiller number, maintain the chlorophyll content, improve the growth and development of rice. At the same time, different rice were difference in the treatment.关键词
