摘要
通过对日光温室种植葡萄10年后,不同土层养分动态变化的研究,结果表明:有机质、全氮、全磷、全钾、铵态氮、硝态氮、速效磷、速效钾含量、电导率、水溶性盐分和阳离子交换量在0-20cm与20-40cm土层间变幅最大,且随着土层深度的增加呈显著降低趋势。土壤p H也在0-20cm与20-40cm土层间变幅最大,且随着土层深度的增加呈显著提高趋势。为了平衡和调整各土层养分,提高地表养分利用率,建议深翻土壤和地表间作浅根性蔬菜。
Fertility dynamic change of different soil layer was studied after planting grape ten years in greenhouse, the result showed that the amplitude of organic matter, total nitrogen, total phosphorus, total potassium, ammonium nitrogen, nitrate nitrogen, available phosphorus, available potassium content, conductivity, water soluble salt content and cation exchange capacity were the highest between 0-20cm and 20-40cm soil layer, and which were decreased with soil depth increased. The amplitude of soil pH was the highest between 0-20cm and 20-40cm soil layer too, and which was increased with soil depth increased. Digging under to great depth and planting shallow root vegetables between grapes were suggested to balance and adjust fertility of different soil layer and increase fertility availability of surface.
