摘要

随着种植年限的增加

与露地和大田相比

保护地土壤在温度、湿度、空气、水分等环境条件

土壤有机质、全氮、速效氮、磷、钾、钙镁、酸碱度及生物活性等理化和生物性质、土壤盐分累积等均发生了巨大的变化会给土壤质量、作物生长及人类健康带来危害。为了保证高产、优质、高效的蔬菜生产

研究保护地土壤理化性状及障碍因素具有重要的理论和实践意义。

Abstract

Compared to the soil in cereal cropland

the physical

chemical and biological properties of the soil in the protected field

such as organic matter

total N

available nutrient(N

P and K)

exchangeable Ca and Mg

(acidity) and alkalinity

salinity accumulation and bio-activity

have obviously changed with the prolongation of cropping duration.This has decreased soil quality

impacted crop growth and potentially threatened human health.In order to sustain the vegetable production with high yield

high quality and high efficiency

it is of great theoretical and practical significance to study soil fertility and its affecting factors in the protected field cropping system.
