沼液-秸秆深施对大棚黄瓜生长及产量的影响

Effect of Biogas Slurry-straw Deep Application on Growth and Yield of Cucumber in Greenhouse

以大棚"瑞青"黄瓜为试材,采用沼液-秸秆深埋技术,研究了沼液小麦秸秆和沼液水稻秸秆处理深施对大棚内部环境和黄瓜生长的影响。结果表明:2种沼液秸秆深施处理均能显著提高棚内二氧化碳浓度,增高棚内气温和土温,降低土壤盐渍化程度;促进黄瓜生长发育,提高黄瓜经济产量。其中沼液小麦秸秆较之于沼液水稻秸秆对大棚内环境和黄瓜生长的影响更加显著。

‘Ruiqing＇cucumber was used as material,the effects of different biogas slurry-straws on‘Ruiqing＇cucumber growth were studied in greenhouse by using slurry-wheat straw and slurry-rice straw deep application.The results showed that both biogas slurry-straws could increase CO_2 concentration,soil temperature and air temperature,and reduce the degree of soil salinization markedly.Also,the growth and economic yield of cucumber were remarkably enhanced compared with the control.In addition,the impact of the slurry-wheat straw on the greenhouse environment and the cucumber growth was more significant than that of slurry-rice straw.
