定植后的大棚黄瓜长期生育在薄膜密闭的环境中,棚内二氧化碳气含量不能及时得到补偿,影响了黄瓜的产量.为研究增施二氧化碳对黄瓜产量的影响,我们于1991年4月21日至5月28日,在板石镇金英村三社金永昌等农户的大棚黄瓜生产中,进行施放二氧化碳气的试验研究,现将试验结果报告如下. 试验采用简单对比法,以金永昌栽培的两栋棚面积、品种、土质和管理条件(除施放CO_2棚和不施放CO_2外)相同的棚互为对照。其它户的三栋黄瓜棚作为施放二氧化碳的一般观察棚.晴天早7时一亩地棚吊放5个塑料盆、0.8亩地的棚吊放4个塑料盆、0.6亩地的棚吊放3个塑料盆.吊放位置始终保持超过黄瓜
Long-term colonization of greenhouse cucumbers after planting in a film-enclosed environment, the shed carbon dioxide gas content can not be compensated in time, affecting cucumber production.In order to study the impact of increased carbon dioxide on cucumber yield, we April 21, 1991 to On May 28, in the production of greenhouses and cucumbers produced by Jin Yong Village, Jinyuncun, Banchou Town, the experimental study on the release of carbon dioxide gas was reported. The test results are reported as follows: The test was conducted by simple comparison method The two sheds, breeds, soil quality and management conditions (except for the CO_2 shed and non-CO_2) were the same for each other. Three cucumber sheds of other households are used as general observation sheds for the release of carbon dioxide. The sunny morning 7 o’clock and 1 mu of mullions shed 5 plastic basins and 0.8 mu of sheds for hanging 4 plastic basins and sheds of 0.6 mu A plastic basin. Always hold the hanging position cucumber
