摘要
日光温室秋冬茬甜瓜在施足有机肥和秸秆堆肥时 ,生长前期棚内CO2 浓度较高 ,中午 12 :0 0左右放风时棚内CO2 浓度缓苗期为 1810mg·L- 1,留瓜期 12 0 0mg·L- 1,授粉期 1370mg·L- 1;授粉期夜间CO2 积累最快 ,平均增加 140mg·L- 1·h- 1;膨大期放风前冠层CO2 下降量最大 ,平均每 10min(分 )下降 150mg·L- 1;垄面土壤平均比沟内CO2 释放量多 142g·m- 2 ·h-
When sufficient manure and well composted stalks were applicated in lean to solar greenhouse,the CO 2 concentration remained at relatively higher level during early development stages of melon. The CO 2 concentration at 12:00 (noon before vetilation) still kept 1810mg·L -1 at transplant recovering stage,1370mg·L -1 at pollination stage and 1200mg·L -1 at fruit setting stage. The accumulation rate of CO 2 at night was highest and reached 140mg·L -1 ·h -1 at the stage of pollination. The deduction rate of CO 2 in canopy was fastest and reached 150mg·L -1 per 10min after sunrise at the stage of fruit development. CO 2 released from soil on the raised beds was 142g·m -2 ·h -1 more than that in furrows.
