生态基质无土栽培关键技术主要解决我国设施土壤连作障碍严重、设施蔬菜生产效益不高、耕地和水资源严重不足等问题。主要包括生态基质原料前处理技术、基质理化性质调控技术、营养调控技术和生产管理技术等。该技术适应于我国设施土壤连作障碍严重的老菜区及各种荒地、盐碱地、废矿区和中低产田(图1)。1技术操作要点1.1栽培设施准备采用栽培槽的形式。栽培槽大小:内径48 cm(果菜)或96 cm(叶菜),长度依温室的宽度而定,槽间距72 cm(果菜)或30 cm(叶菜)。栽培槽铺设0.1 mm厚的聚乙烯塑料薄膜与地面隔
The key technologies of soilless culture of ecological substrate are mainly to solve the problems such as the obstacle of soil continuous cropping in facilities, the inefficiency of vegetable production in facilities and the shortage of arable land and water resources. Including the ecological substrate material pretreatment technology, physical and chemical properties of matrix control technology, nutrition control technology and production management technology. The technology adapted to China’s facilities for continuous cropping obstacles serious old vegetable area and a variety of wasteland, saline-alkali land, waste ore and low-yield fields (Figure 1). 1 technical points of operation 1.1 cultivation facilities ready to use the form of cultivation trough. SIZING 48 cm (fruit) or 96 cm (leaf), depending on the width of the greenhouse. Slot pitch 72 cm (fruit) or 30 cm (leaf). Cultivation trough laying 0.1 mm thick polyethylene plastic film and the ground compartment
