气候因素对鲁西南棉花生长、产量和品质的影响

应用鲁西南1980-2009年植保部门棉花资料和气象部门气象资料,利用DPS专业版数据处理系统筛选一批影响棉花生长、产量和品质最优势相关气象因子,分析其相关性及对棉花生长、产量和品质的影响。结果表明:棉花衣分与7月降水量呈显著负相关;8月充足的光照有利于棉花裂铃、吐絮;9月降水量偏多,铃重严重减少。铃重随5月和8月平均气温升高而增加。铃重与5月日照时数呈正相关,光照充足,铃重增加;适宜的降水量对棉花纤维长度有利,降水量过大则棉花纤维长度减小。棉花皮棉及籽棉的产量均与年平均气温呈极显著正相关,说明气温偏高有利于棉花产量形成。分析气候因素对棉花生长及产量的影响,对发展当地棉花产业具有重要意义。

Effect of Climate Factors on Cotton Growth,Yield and Quality in the Southwest of Shandong Province

Based on the cotton data of the plant protection department and meteorological data of the meteorological department from 1980 to 2009 in the southwest of Shandong province,the possible effect of climate factors on cotton were analyzed,and this provides reference for high cotton production in the local area.Using professional data processing system DPS,several most dominant meteorological factors that affect cotton growth,yield and quality are chosen,and its correlation and effects were analyzed.The results...
