不用土壤,在岩棉上浇营养液种植蔬菜是一项蔬菜栽培新技术。岩棉栽培技术在荷兰、日本等国家的无土栽培中应用较早。荷兰岩棉栽培,使黄瓜生长期延长到240多天,亩产高达1.5～2.5万公斤。应用岩棉生产蔬菜,能早熟、高产、品质好、无公害、省工、省水、省肥。一、岩棉栽培设施1.栽培床将岩棉制成长1米,宽20厘米,厚8～10厘米的长方块,白色塑料薄膜做成筒状,将岩棉块包在筒内,筒两头不包。应用时可将几块岩棉块接合成一个栽培床。各栽培床的间距按不周作物而定,一般为1.2～1.5米.也可用宽窄行设置,宽行2米左右,窄行0.6～0.8米。
No soil, the nutrient solution in the rock wool planting vegetables is a vegetable cultivation of new technologies. Rockwool cultivation techniques in the Netherlands, Japan and other countries in the soilless culture earlier. Dutch rock wool cultivation, the cucumber growth period extended to more than 240 days, up to 1.5 to 25,000 kg per mu. Application of rock wool production of vegetables, can be early maturity, high yield, good quality, pollution-free, labor-saving, water-saving, fertilizer. I. Rockwool cultivation facilities 1. Cultivation bed Rock wool made of 1 meter long, 20 cm wide, 8 to 10 cm thick rectangular box, made of white plastic film tube, the rock wool wrapped in the tube, tube two Not included. Application can be a few rock wool blocks into a cultivation bed. The spacing of cultivation beds according to the unsightly crop may be, generally 1.2 to 1.5 meters. Can also be used to set the width of the line, about 2 meters wide, 0.6 to 0.8 meters narrow line.
