摘要
研究了亚高温条件下不同补充灌溉量(80%ET、100%ET、120%ET)对辣椒幼苗质量的影响。结果表明,在亚高温条件下,补充灌溉120%ET的幼苗株高、茎粗、株幅、净光合速率、干物质积累量等指标均最高,并且与80%ET处理间差异显著。植株的壮苗指数与生长函数均为补充灌溉120%ET>100%ET>80%ET。在亚高温条件下,120%蒸腾蒸发量的补充灌溉有利于温室辣椒幼苗的健壮生长。
The influences of different irrigation amounts(SO%ET, 100%ET and 120%ET) on the quality of pepper seedlings under sub-high temperature in greenhouse were studied. The results showed that the plant height, stem diameter, width, the net photosynthetic rate and accumulated dry matter of seedlings under 120 % ET of irrigation amount were all higher than those in other treatments. There was a significant difference between 120 % ET and 80 % ET of irrigation amount. Both the seedling's healthy index and growth function were 120%ET〉100%ET〉80%ET. 120%ET of irrigation amount under sub-high temperature was favorable to pepper seedlings growth.
