一、塑料栽培袋的制作用厚度为0.08—0.1毫米,乳白色,折径为40厘米的塑料吹塑筒,按73厘米长截成段。将每段一端焊死,另一端开口,即成有底的塑料栽培袋。二、准备基质基质可用草炭和蛭石(1:1),因草炭的pH值在4左右,因此,每立方米草炭要加3公斤石灰石粉调酸,在草炭和蛭石内掺入长效化肥,特别是磷肥,另加微量元素,基质和肥料一定要混均匀,把混均匀的基质装入塑料袋内,然后封口成为枕头状备用。三、供液系统——滴灌设施(营养液不循环) 应用无土栽培技术,必须有一套可靠的营养液装置和供液系统。 1.对供液系统的要求
First, the production of plastic bags used with a thickness of 0.08-0.1 mm, milky white, 40 cm off the plastic blow molding tube, cut into segments by 73 cm long. One end of each segment welded to death, the other end of the opening, that is, the end of the plastic bag cultivation. Second, the preparation of matrix substrate available peat and vermiculite (1: 1), because of peat pH value of about 4, so every cubic meter of peat to add 3 kg of limestone powder acid, peat and vermiculite mixed long-term Fertilizers, especially phosphate fertilizer, plus trace elements, matrix and fertilizer must be mixed evenly, the mixed substrate into a plastic bag, and then sealed into a pillow-like spare. Third, the liquid supply system - drip irrigation facilities (nutrient solution does not cycle) Application of soilless cultivation techniques, there must be a reliable nutrient solution and liquid supply system. 1 for the liquid system requirements
