日光温室营养液膜栽培技术是无土栽培的一种,它是不用土壤而让番茄生长在间歇流动的浅层营养液中的一种种植方式,故被称为纯“水培”法.试验表明:66m~2产量高达1.6万kg,效益在3.2万元以上,纯收入1.5万元左右,可取得良好的经济效益和社会效益.一、栽培设施及自控系统番茄营养液膜栽培一般在日光温室中进行,栽培设施由栽培槽(长40～50m)、贮液池(3～6m~3)、微型泵及管道系统和自动调控系统构成.营养液输液系统是在温室内顺其自然坡降的1/25～1/80比降,挖成宽30cm,深10cm的栽培土槽,上面用宽60cm的黑塑料膜铺垫.铺垫的黑塑料膜底部用两根20号铁丝撑开,中间用一根8号铁丝拉起,用木夹将黑膜夹在8号铁丝上,形成一个剖面为三角形的栽培槽.贮液池设在温室的一端,由微型泵将营养液输送到槽的最高处,然后其因重力缓缓流回贮液池.微型泵一般可选用电压220v、功率370w或550w的
Sunlight greenhouse nutrition liquid film cultivation technology is a kind of soilless culture, it is without soil so that tomato growth in the intermittent flow of shallow nutrient solution in a cultivation, it is called pure “hydroponics” method. The results show that the yield of 66m ~ 2 is as high as 16,000 kg, the benefit is more than 32,000 yuan, and the net income is about 15,000 yuan, which can achieve good economic and social benefits. I. Cultivation facilities and automatic control system Tomato nutrition liquid film cultivation is generally carried out in sunlight Greenhouse, cultivation facilities by the cultivation tank (length 40 ~ 50m), storage tanks (3 ~ 6m ~ 3), micro-pump and piping systems and automatic control system.Nutrient solution infusion system is in the greenhouse along its natural slope Drop 1/25 ~ 1/80 ratio drop, dug into 30cm wide, 10cm deep soil trench cultivation, the above with a 60cm wide black plastic film bedding. Underlay the black plastic film at the bottom with two 20 wire propped open, the middle With a 8 wire up, the black clip with a wooden clip on the wire clip on the 8th, the formation of a triangular cross-section of the cultivation tank. Storage tank at one end of the greenhouse, the micro-pump will be nutrient solution transported to the tank The highest point, and then slowly due to gravity back to the reservoir.Mini pump generally can use voltage 220v, power Rate of 370w or 550w
