摘要

为了探明天水地区长期种植果树对果园土壤肥力的影响

应用时空互代法

对不同种植年限的樱桃果园土壤养分和酶活性进行了研究。结果表明

随着种植年限的增加

土壤养分和酶活性(除多酚氧化酶)均可用二次函数进行拟合。不同种植年限间土壤养分含量和酶活性差异显著。土壤有机质、速效磷、脲酶、碱性磷酸酶和纤维素酶活性与种植年限之间存在显著或极显著相关关系。通过相关分析和通径分析发现

土壤酶活性与土壤养分之间呈显著或极显著相关关系。

Abstract

The spatial-temporal substitution method was applied to explore the effects of planting period on the soil fertility by soil nutrients and soil enzyme activities in cherry orchards around Tianshui region.It indicated that the quadratic function fitting could be used in analog the variations of soil nutrients and its enzyme (except polyphenoloxidase)activities with the increase of the planting period.Both soil nutrients and soil enzyme activities varied significantly with different periods of planting.A significant

even extremely significant correlation existed between planting years and soil organic matter

available phosphorus

sucrase activities

alkaline phosphatase activities

cellulase activities.So did with the correlations between soil enzyme activities and soil nutrients content.
