| 摘 要： | 针对温室黄瓜生产中CO2浓度亏缺和地温偏低的问题,对秸秆生物反应堆技术进行了研究。结果表明：应用秸秆生物反应堆技术可提高温室内CO2浓度,在任何时刻均约为无秸秆温室内CO2浓度的1倍,并始终高于外界CO2浓度,满足了温室黄瓜生长发育的需要。应用秸秆生物反应堆技术能提高地温,与对照相比,10 cm地温提高1.13~1.52℃,20 cm地温提高1.71~2.01℃。黄瓜植株长势优于对照,可提早5 d采摘,前期产量提高30.58%,收益显著增加。

| Abstract: | According to the problems of CO2 deficit and low ground temperature in the cucumber production in solar greenhouse,the straw bio-reactor technology was studied.The results showed that the straw bio-reactor could increase the CO2 concentration and ground temperature in greenhouse,which could meet the needs of growth and development of cucumber.The CO2 concentration increased by almost one time than that in the greenhouse without straw at any time,and was always higher than that in the external environment.Th... |
