摘要：

采用传统统计和地统计相结合的方法，对面积约200ha的孟酄村葡萄园0-30cm土壤养分进行了空间变异特性和分区平衡施肥技术研究。结果表明，土壤N、P、Mn、Zn、S变异较大，测试值变异系数在之间。土壤Ｎ、Mn含量空间分布趋势以大块状变异为主，具有较强的渐变性分布规律。而土壤P、K、Zn、B含量空间分布则以小块状变异为主。基于土壤养分空间分布规律的分区平衡施肥技术的应用，能够大幅度增加葡萄产量，显著提高经济效益。分区平衡施肥与常规施肥相比，葡萄增产幅度为13.7~14.8%，增收幅度为17040~17820 RMB yuan ha-1。

Abstract:

Spatial variability and regionalized balanced fertilization technology of soil nutrients in a grape region with an area of 200ha was studied using geo-statistics.The results showed that the grape region was widely variation in N, P, Mn, Zn and S, the C.V. was 35.1~63.3%. Spatial distribution map of soil nutrient content showed that soil N, Mn contents were changed with big blocks, soil P, K, Zn, B contents were changed with small blocks. With regionalized balance fertilization technology on grape, yield increased by 13.7% to14.8 %, economic profit by 17040 to 17820 RMB yuan ha-1。
