无土栽培是蔬菜生产技术上的一项重大革新,它可以通过配套设施在不适宜于蔬菜生产的环境条件下进行生产.水培是无土栽培的一种主要方式,又叫营养液栽培.我场于1993年年底,投资60余万元,开始筹建25亩,是目前上海郊区规模最大的无土栽培设施.最近已陆续投产.我们为了摸索水培生菜的生长情况,与土培作了比较试验.一、材料与方法供试品种:散叶生菜,供试面积:0.3亩中棚各1只,设营养液深水栽培和土培2个处理.生菜水培与土培均於1月3日播种,育苗池中用电热地加温线加温,功率为80W/m~2.齐苗后通过锻
Soilless cultivation is a major innovation in vegetable production technology that can be produced through ancillary facilities in an unfavorable environment for vegetable production. Hydroponics is a major method of soilless culture, also known as nutrient solution cultivation. At the end of 1993, I invested over 600,000 yuan to start the construction of 25 mu, which is the largest soilless culture facility in Shanghai suburbs and has been put into operation recently. In order to explore the growth of hydroponic lettuce, we made a comparative experiment with soil culture Materials and methods The test varieties: loose leaf lettuce, the test area: 0.3 acres in the shed each set nutrient solution deep water cultivation and soil culture 2. Lettuce hydroponics and soil culture are in the January 3 Sowing, nursery pond heating with electric heating line, the power of 80W / m ~ 2. Qi Miao after the forging
