【摘要】 经过对国内外水培技术中各自独具特色的增氧技术和方法的总结和分析 ,提出了营养液深液流栽培的动态液位增氧法 (DSS)。DSS利用了滴液法、液流法、露根法、湿气根法等几方面增氧的原理和方法。应用动态液位法栽培番茄的试验表明 ,动态液位法可以提高植株的相对生长率、加快叶片和节点的生长、增强根系的活力、促进根系的生长发育。更多还原

【Abstract】 By summarizing and analyzing the hydroponic techniques in the world, especially their unusual oxygen-enrichment methods and techniques, the technique of DSS was firstly put forward in the tomato infinitive-growth-typed cultivated by deep nutrient solution flow. The DSS used such oxygen-enrichment principles and ways as liquid-drop, liquid-flow, root-revealed and root-wet, etc. Checked by tomato planting experiments, using the DSS would increase plant respective growth rate, accelerate leaves and stem burls to grow, strengththe activity of roots and improve the growth and development of the root system. If the DSS was improved in the future, it was believed to be well used in large area practical production, besides the infinitive-growth-typed cultivated by deep nutrient solution flow culture.更多还原
