新疆地处我国西北内陆,土壤有机质贫乏,结构不良。气候干燥,多风,春季寒流频繁入侵,变温剧烈。对农作物,尤其是集约型的瓜菜作物生长发育甚为不利。近年来,从日本引进的塑料薄膜地面复盖栽培(简称地膜复盖栽培)技术,对我区瓜菜类作物的保苗,早熟,增产,增收作用显著。为了进一步挖掘地膜复盖的增产潜力,有必要对地膜复盖后的作物生长发育和作用机制进行深入研究,以便因地制宜地制订出适合本地自然条件的管理技术措施。
Xinjiang is located in the inland of our country’s northwest, soil organic matter is poor, poor structure. The climate is dry, windy, frequent intrusion of cold seasons in spring, severe temperature changes. Crops, especially the intensive growth of cucumber crops is very unfavorable. In recent years, the plastic film from Japan covering the ground cover cultivation (referred to as plastic film mulching cultivation), my area of melon vegetables seedlings, precocious, increase production, income significantly. In order to further excavate the yield potential of plastic film mulching, it is necessary to conduct an in-depth study on crop growth and development and its mechanism after mulching, in order to formulate management technical measures suitable for local natural conditions according to local conditions.
