中文摘要:
      采用土壤栽培、有机生态型无土栽培、无机耗能型无土栽培三种栽培方式,进行生菜三次采收四层立体栽培试验。结果表明:采用有机生态型无土栽培进行生菜分次采收立体栽培,可有效降低产品中硝酸盐含量,提高根冠比和相对生长速率,变一次性收获为三次采收,可使每盘产量提高30%以上,变平面栽培为4层立体栽培,使温室复种指数提高4倍。
英文摘要:
      The test of stereoscopic cultivation with four layers is carried through with soil cultivation,organ ic ecotype soilless cultivation and inorganic en ergy-consumed type soilless cul tivation in lettuce.The re sults indi cated that it can reduce effectively nitrate content of product to adopt organic ecotype soillesscul tivation with several harvests in lettuce.It can also elevate ratio of root to coronal and relative growth speed.Picking three times can increase output of each tray by more than30%and greenhouse mul tiple crop ping in dex four times.
