番茄的营养液膜栽培配套技术研究

营养液膜技术(Nutrient Film Technique)作为第三代水培新技术,在克服连作障碍、生产无公害蔬菜和提高蔬菜产量上具有明显优越性。作者以营养液膜技术,结合我国国情,在栽培设施、供液方式、育苗和定植方式、营养液更新方法、合适的营养液浓度和管理方法等方面,进行简易化栽培研究,使得番茄增产增值,成本大幅度降低,基本形成了现阶段我国保护地番茄营养液膜栽培配套技术规范。

STUDIES ON COMPLETE SERIES OF NFT (Nutrient Film technique) OF TOMATO

NET as the third generation of the new technique of hydroponics was evidently advantageous in overcoming continuous cropping obstacles , producing non-polluted vegetables and increasing vegetable yield. According to the practical circumstances of our country , the authors studied to realize simplification of cultural technics in the follow respects of NFT: culture installation , ways of supplying nutrient solution , raising and transplanting of seedilings , renovation of nutrient solution management methods and proper concentration of nutrient solution etc .in order to increase tomato yield and profit and to reduce prodution cost by a big margin .The standard of complete series of NFT of protected tomato cultivation was basically formed at the present stage.
