| 摘 要： | 研究了生长介质中起始肥料类型对养分淋洗的影响及灌溉方式对生长介质pH和电导率(EC)的影响。结果表明,以速效肥作起始肥料时,上浇水可导致大量养分淋失,而下浇水则加剧了生长介质中盐分的积累;无论使用何种肥料,与下浇水比较,上浇水降低了生长介质的pH和电导率。

| Abstract: | The influences of Start fertilizer types and irrigation on nutrient leaching,pH and EC of growing media were studies. It was shown that top irrigation wouldled to nutrient leaching when normal chemical fertilizer was employed. No matter which kinds of fertilizer employed, bottom irrigation resulted in higher pH and EC relative to those when water was irrigated from top. bottom Irrigation accelerated salt accumulation when normal chemical fertilizer was used. |
