摘  要:
春季对大棚瓠瓜增施CO2,可促进植株的生长发育.株高、茎粗增幅分别达到3.90%~19.48%和11.58%~27.37%,叶片厚度及叶面积也分别增加38.46%~69.23%和26.09%~49.38%;第一雌花着生节位平均降低 2.6~4.0节.平均单果重增加 4.05%~19.62%,产量提高 8.65%~19.47%.在1000μmol·mol-1范围内,CO2浓度每增加100μmol·mol-1,单果重和产量分别增加31.97g和68.39kg·667m-2;第一雌花着生节位降低0.35节.在1000μmol·mol-1浓度下,瓤瓜光合速率和羧化速率均达最高值.春季大棚瓠瓜CO2适宜施用浓度为1000μmol·mol-1左右.

摘  要:
In vegetable growing under protection, lack of carbon dioxide is one of the most important factors limiting photosynthesis. The application of 600 - 1200 μmol·mol-1 CO2 in the plastic house increased photosyntheitc rates and ratio of C/N, promoted both vegetative and reproductive growth of bottle gourd plants. Plant height, stem diameter, leaf thickness and leaf area increased by 3.90-19.48%, 11.58-27.37%, 38.46-69.23% and 26.09-49.38%, respectively. Average single fruit weight and yield were 4.05-19.62% and 8.65-19.47% higher than that in normal air. Primary female flower position was lowered by 2.6-4.0. Net photosyntheitc rate and the carboxylase activity of RuBP were greatest under CO2 1000μmol· mol-1. The optimal concentration of CO2 applied to bottle gourd in spring was about 1000 μmol·mol-1.
