摘要
本文通过对泉州市典型农田不同作物、不同施肥年限、不同利用方式及土壤类型的地力贡献率进行试验分析,得出农田地力贡献率的主要特点为养地作物高于耗地作物、逐年下降且3年后暂趋稳定、从土壤高肥力到低肥力逐渐下降,进而探讨其在配方施肥中的应用。
Percentage of soil fertility contribution to grain crop yield under different grain crops, different fertilization time, different utilization methods and different soil type in typical farmlands of Quanzhou were analyzed, it＇s obtained that percentage of soil fertility contribution to grain crop yield of soil improving crop was higher than crop of depleting soil fertility, decreased year by year, after 3 years, it trends satable, it trends decreasing from high fertility to low fertility, application on formula fertilization was approached.
