摘要
膜下滴灌施肥技术,不仅可节约该区宝贵的水资源,而且可使原来一些采用常规灌水施肥方法不适宜种植的土地,如荒地、甚至沙漠种植变为现实。但是,在膜下滴灌栽培管理问题中值得指出的是,滴灌施肥作为一项施肥措施,其应用效果取决于它对养分和水分调控与当地气候和土壤特性、作物需肥规律的吻合程度。只有这些条件都处于协调状态时,才可发挥这一技术的增产效果。否则,可能会产生一些不良的影响。
The fertiliztion techniques of drip irrigation under membrane not only can save the water resources of the region but also can make some non - cultivable land(wasteland and desert ete. )into cultivable land by the use of conventional fertilization techniques of drip irrigation. But the fertilization effect of cultivation management of drip irrigation under membrane mainly depends on regulation of nutrient and water and the characters of the local climate and soil and fertilization suitable for the plants. Only when all the above conditions are in coordination with each other, this technique can perform the full effect of increasing produ - ction.
