摘要
利用地统计学原理和3S技术,对上海市松江区朱定村2000余亩耕地进行50m×50m的网格取样,在进行土壤养分的空间变异分析等工作的基础上,建立了精准农业分散经营管理模型。应用此模型对西瓜和水稻进行推荐施肥应用的研究,结果表明推荐施肥不仅可以给西瓜和水稻提供平衡的营养,而且可以在降低总养分量的基础上,提高西瓜产量14%-27%,提高水稻产量10%左右,使土壤养分的管理趋于更加合理。
The discrete management mode was built with geo-statistics and 3S technology in Zuding Village, Songjiang County, Shanghai, after sampling soil with grid of 50m×50m and analysis of soil nutrients spatial variance. Recommended fertilization on rice and watermelon was studied with the discrete management mode. The results showed that recommended fertilization not only provided rice and watermelon balanced nutrients but also invreased the yield of rice 14-27% and the yield of watermelon about 10% which decreas...
