| 摘 要： | 目的]分析通化地区水稻(Oryza sativa L.)移栽后积温与其产量性状的相关性,明确通化地区的积温状况对产量性状的影响。方法]对通化地区1999～2005年6～9月各月、旬的积温与水稻产量性状进行相关性分析。结果]每穴穗数和每穴粒数与7月份的积温呈显著正相关(r=0.810*,r=0.755*);结实千粒重与7月份的积温呈显著负相关(r=-0.855*);穗长与7月上旬的积温呈显著负相关(r=-0.794*);混合千粒重与7月下旬的积温呈显著负相关(r=-0.830*),与9月中旬的积温呈极显著正相关(r=0.876**);结实千粒重与7月上旬积温和8月下旬的积温都呈显著负相关(r=-0.790*,r=-0.791*);空粒率与9月上旬的积温呈显著正相关(r=0.762*),而与9月中旬的积温呈极显著负相关(r=-0.920**);秕粒率与8月上旬积温呈显著负相关(r=-0.780*);成熟度与7月下旬的积温和9月上旬的积温呈显著负相关(r=-0.757*,r=-0.773*),与8月下旬的积温呈显著正相关(r=0.772*);结实率与9月上旬的积温呈显著负相关(r=-0.762*),而与9月中旬的积温呈极显著正相关(r=0.921**)。结论]该研究可为改进水稻栽培技术,进一步为通化地区水稻高产优质栽培提供理论参考。

| Abstract: | Objective] The purpose was to analyze the correlation between accumulated temperature and yield traits of rice after transplanting in Tonghua Area,and confirm the effects of accumulated temperature of Tonghua Area on yield traits of rice.Method] Correlation analysis of accumulated temperature and rice yield traits in Tonghua Area during June to September from 1999 to 2005 were analyzed.Result] Panicle number and grain number per hole was significantly positively correlated to the accumulated temperature in July(r=0.810*,r=0.755*);seed setting kernel weight was significantly negatively correlated to the accumulated temperature in July(r=-0.855*);spike length was significantly negatively correlated to the accumulated temperature in the first ten days of July(r=-0.794*);mixed kernel weight was significantly negatively correlated to the accumulated temperature in the third ten days of July(r=-0.830*),but very significantly positively correlated to the accumulated temperature in the second ten days of September(r=0.876**);seed setting kernel weight was significantly negatively correlated to the accumulated temperature in the first ten days of July and the third ten days of August(r=-0.790*,r=-0.791*);percentage of empty grains was significantly positively correlated to the accumulated temperature in the first ten days of September(r=0.762*),but significantly negatively correlated to the accumulated temperature in the second ten days of September(r=-0.920**);percentage of unfulfilled grains was significantly negatively correlated to the accumulated temperature in the first ten days of August(r=-0.780*);maturity degree was significantly negatively correlated to the accumulated temperature in the third ten days of July and the first ten days of September(r=-0.757*,r=-0.773*),but significantly positively correlated to the accumulated temperature in the third ten days of August(r=0.772*);seed setting rate was significantly negatively correlated to the accumulated temperature in the first ten days of September(r=-0.762*),but very significantly positively correlated to the accumulated temperature in te second ten days of September(r=0.921**).Conclusion] The study provides a theoretical reference for modifying rice cultivation technology and then deeply realizing high yield and good quality cultivation of rice in Tonghua Area. |
