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。
