- 摘要:
- 通过二因素重复试验研究不同条件、不同栽培密度对水稻产量性状的影响。结果表明:节水处理的水稻分蘖消长动态、不同时期的叶面积指数与常规灌溉有差异, 节水处理条件下, 随种植密度增大, 水稻产量提高, 以B1A1 产量最高, 常规处理则以B2A3 产量高, 与B1A1 持平。节水条件下通过增加水稻种植密度可保证水稻稳产、高产。
- Abstract:
- The effect of different irriga ted w ater and plant density on yield character s of rice th rough two factor sduplica tion trial w as studied.The re sults indicate that the tiller tendencies and leaf area index o f rice w ere diffe rentunder different ir rig ated conditio n.Under restricted irr ig ation , the yield o f rice increased with the plant density increasing, the yield of disposal B1A1 w as the highest , the yield of disposal B2A3 w as the highest under usua l disposal , equal to B1A1 .Increasing plant density could g uarantee stable yield and impro ve y ield of rice under restrictedirrigation .
