连续十年施用不同肥料对土壤养分累积的研究
Effect of Ten-year Successlve Application of DifferentFertilizers on Accumulation of Soil Nutrients
【摘要】 连续十年施肥的处理区,不仅作物产量比对照区高,带走氮、磷、钾量相应增多,而且土壤氮、磷总贮量和有效性含量亦提高,土壤钾素贮量虽略有下降,但都在5%以内,有效钾含量却略有增加。
【Abstract】 The yield and relative N,P,K-removed amounts in the treated block of ten-year succes-sive fertilization were not only higher than that of the check block,but also the reserved and avail-able contents of soil N,P increased.Although the reserved K in soil declined slightly within 5%。the content of available K increased limitedly.
