蔬菜静止法平面无土栽培,具有降低劳动强度,省工、省时,清洁干净,节约用水,不易发生病虫害,而且投资少、操作简单等特点;生产出的蔬菜无污染,品质好,符合发展方向。可在土壤中有害微生物及病虫害严重或土质较差的温室大棚内进行,也可在条件较好的温室大棚内推广。在实际应用中,应做好以下几项工作。一、定植前基础工作 (一)建水池水池是用来稀释营养液的必备设施,如用水泵供液,可建地下池;如用重力滴灌(靠落差自流)可用专用塑料桶,其架设时底部要高出地面1m以上。水池要建在温室入口端,尽量少占地面空间。水池(桶)的大小要根据需要而定,一般每666.7 m~2建2.5 m~3水池即可,每次滴灌前提前几天加好水,以便提高水温。池内壁划上精确刻度,计算出相应
Vegetable stationary method Plane soilless culture, with reduced labor intensity, labor-saving, time-saving, clean, water conservation, not prone to pests and diseases, and less investment, simple operation and other characteristics; produce vegetables without pollution, good quality, in line with the development direction. Can be harmful microorganisms in the soil and pests or pests serious or poor soil in greenhouse, but also in good conditions within the promotion of greenhouse. In practical application, should do the following work. First, the basic work before planting (a) build pool pool is used to dilute the nutrient solution of the necessary facilities, such as the pump for liquid, can be built under the pool; such as gravity drip irrigation (by gravity flow) available special plastic bucket, its erection When the bottom of the ground above 1m above. Pool to be built at the entrance to the greenhouse, as little as possible to account for the floor space. The size of the tank (barrel) according to need, generally every 666.7 m ~ 2 to build 2.5 m ~ 3 pool, every time a few days before drip irrigation water, in order to raise the water temperature. Pool wall planted accurate scale, calculate the corresponding
