无土栽培是先进的农业技术,具有产量高、品质好、不受土壤条件限制的优点,适宜工厂化栽培。无土栽培可分为有基质栽培的水培法和无基质栽培的气培法两种。我市从1979年开始水培试验,1982～1987年又搞了气培试验。气培试验在3个点进行,面积为1300米~2,分别搞二、三层栽培番茄,二茬周年生产,亩产达1.5万公斤,1987年通过技术鉴定。现介绍如下:温室结构与设计安装全光温室长25米,宽20米,高
Soilless culture is an advanced agricultural technology, with the advantages of high yield, good quality and not limited by soil conditions, suitable for industrialized cultivation. Soilless culture can be divided into two kinds of culture method with the cultivation of substrate hydroponics and non-substrate cultivation. The city began hydroponics experiment in 1979, and conducted aerobic experiment in 1982 ~ 1987. Gas-trapping experiments were conducted at 3 sites with an area of 1,300m ~ 2. Secondary and tertiary cultivation of tomatoes was conducted respectively. The second crop was annually produced with a yield of 15,000 kg per mu. In 1987, it passed technical appraisal. Are introduced as follows: Greenhouse structure and design and installation All-green greenhouse length 25 meters, 20 meters wide and high
