不同种植密度和施肥量对杂交油菜叶片叶绿素含量和产量的影响

         

摘要

采用大田小区试验,在6个种植密度和5种施肥水平的不完全方案下,研究优质杂交冬油菜新品种湘杂油763的油菜叶片叶绿素含量和产量的变化.叶片叶绿素含量的测定结果表明:在同一种植密度条件下越冬期和盛花期叶片叶绿素a、叶绿素b和总叶绿素含量均随施肥量的增加而增加.同一施肥量下,只有越冬期叶片叶绿素a含量随着密度的增加而减少,叶绿素b和总叶绿素含量无此规律.叶片叶绿素与籽粒产量之间极显著正相关.%Studies on the changes of grain yield and the chlorophyll contents in the functional leaf of a new hybrid winter oilseed rape variety ( Xiang hybrid No. 763 ) under the tretments of 6 planting densities and 5 fertilizer application levels in the field plot experiment. The results of chlorophyll determination showed that,the contents of chlorophyll a, chlorophyll b and total chlorophyll during the winter and flowering stages increased along with the increase of fertilizer application amount under the same planting density. The content of chlorophyll a decreased along with the increase of planting density during the winter stage under the same fertilizer application level. But the content of chlorophyll b and total chlorophyll did .not show the law like this.The correlation between grain yield and chlorophyll of leaf was extemely significant.
