| 摘 要： | 研究了不同浓度的PDJ溶液对水稻移栽苗生长的影响．结果表明，适当浓度的PDJ能提高水稻幼苗的抗干燥性和抗寒性，特别能提高抗干燥性；促进根系生长，促进分蘖；促进干物质的累积，从而提高了谷粒产量其中10mg／kgPDJ喷雾处理，提高了单株产量16．7％，差异显著；0．05mg/kgPDJ浸根处理，提高了单株产量20．8％，差异极显著。

| Abstract: | The research is about how different concentrations PDJ affects the growth of rice transplant seediings. The results indicates suitable concentration PDJ can improve drought resistance and cold resistance,especially drought resistance;advance the growth of root system and dry matter accumulation; so as to improve grains yield. Of all teatments, 10mg/kg PDJ spraying treatment with 16 .7% increase of the yield per stem is significance;0 .05mg/kg PDJ root soaking with 20. 8% increase is very significance. |
