| 摘 要： | 采用聚类分析法,对水旱2种不同水分处理的12个不同生态类型的夏玉米品种灌浆特性进行分析研究,以期探明水分对不同生态型夏玉米产量及灌浆特性的影响。结果表明:灌水处理对金赛29、浚单20、郑单958、中科4号的增产效果最为明显,而对浚单009、浚单18有一定的减产作用;灌水处理对不同品种的平均灌浆速率和灌浆持续时间都有不同程度提高,金豫8号、中科4号、浚单18的平均灌浆速率均有较大幅度提高;根据玉米的灌浆特性和产量,对12个玉米品种进行聚类分析,水旱两种处理均分为三类。

| Abstract: | In order to investigate the filling characteristic of the main promoted corn varieties under irrigation and drought condition in Huang-huai-hai area,12 corn varieties were selected and cultivated in irrigated land and rainfed land.Study was made on dry matter accumulation quantity,filling rate and yield of these varieties.The results show that: Irrigation has the most obvious yield-increasing effect to the varieties of Jinsai29,Xundan20,Zhengdan958 and Zhongke No.4;but has reverse function to Xundan009 and ... |
