为解决北京农业面临的用水和用工压力,北京市农业技术推广站从2014年起引进果菜复合无土栽培技术,吸收以往基质栽培和水培等无土栽培技术优势,进一步促进根系对水肥的均衡吸收。试验表明,无土栽培技术较常规土壤栽培节水46%,用工效率提高1~2倍。
In order to solve the pressure of water and employment in Beijing agriculture, Beijing Agricultural Technology Extension Station introduced fruit and vegetable compound soilless cultivation technology from 2014 to absorb the advantages of soilless culture techniques such as matrix cultivation and hydroponics, and further promote the balance of water and fertilizer absorb. Experiments show that soilless cultivation techniques than the conventional soil cultivation 46% water saving, labor efficiency increased by 1 to 2 times.
