近年来我国对无土栽培方式进行了广泛研究。发展较快,但大部分都停留在试验范围内,具有一定生产规模的无土栽培并不多见,其原因除技术方面外,主要是受到设备条件及生产费用太高的限制。从国外发展和我国目前的生产条件看,采用基质的无土栽培方式比较适合我们的生产情况。一、温室采用无土栽培的好处 1986年开始在河间县地热实验总场进行黄瓜无土栽培生产。利用地下热水为热源,建成北京改良式温室,共三栋,面积约三亩。无土栽培和普通栽培相比具有以下优势: 1、植株生产发育快,无土栽培播种后
In recent years, our country has conducted extensive research on soilless cultivation methods. The rapid development, but most of them stay within the experimental range, with a certain scale of production of soilless cultivation is rare, except for technical reasons, mainly due to equipment conditions and production costs are too high restrictions. From the perspective of foreign countries and the current production conditions in our country, the soil-less cultivation method using the matrix is more suitable for our production. First, the benefits of soilless culture with greenhouse In 1986 began in Hejian County, the total field geothermal experiment cucumber soilless culture production. Use of underground hot water as a heat source, built Beijing improved greenhouse, a total of three, an area of about three acres. Soilless culture compared with ordinary cultivation has the following advantages: 1, rapid development of plant production, soilless culture sowing
