果树业作为肯福环境移民示范区的一项长期的支柱产业 ,在示范区移民的生产、生活中起着不可缺少的作用 .为了解示范区园类用地 (主要是宜果类用地 )开发利用对土壤肥力变化的影响 ,以便更好地指导移民进行合理的综合性开发 ,特对开垦前 (1 996年上半年 ,此时移民也开始迁入 )和开垦后第三年 (1 998年下半年 )示范区的园类用地土壤养分变化进行了调查研究 ,分析了耕层土样的 8个土壤养分指标 ,结果表明 :示范区园类用地土壤肥力整体上基本保持不变 ,但表现出微弱的下降趋势 ;其中的长绿果树地土壤肥力略有下降 ,而落叶果树地土壤肥力有极微的上升趋势 ;不同的土壤养分元素含量变化又有差异 .
As a long-term pillar industry in the demonstration area of Kempo Environmental Immigrants, the fruit tree industry plays an indispensable role in the production and livelihood of immigrants in the demonstration area.In order to understand the development and utilization of the land for demonstration area (mainly the land for suitable fruits) On the impact of changes in soil fertility in order to better guide the rational and comprehensive development of immigrants, especially before the reclamation (in the first half of 1996 when immigrants began to move in) and the third year after reclamation (in 1998 Six months), the changes of soil nutrients in the parkland of the demonstration area were investigated. Eight soil nutrient indicators of the topsoil were analyzed. The results showed that the soil fertility of the parkland in the demonstration area basically remained the same, but showed weakness The soil fertility of evergreen fruit trees decreased slightly, while the soil fertility of deciduous fruit trees had a slight upward trend; the content of nutrients in different soil varied again.
