摘  要:
【目的】为加强兵团农田土壤养分的管理以提高农田钾素养分的产出效率提出建议。【方法】利用兵团第二次土壤普查以来的农田土壤钾素养分变化和20年来的农田钾素养分的投入状况的资料进行了综合统计分析。【结果】阐述了兵团农田土壤钾素含量降低及施钾增产的原因,认为兵团农田土壤钾素含量虽有降低的趋势,但是与全国相比仍属于极高水平,过多的和不合理的钾肥投入不仅会导致生产成本增加,还会造成钾素养分产出效率的降低。【结论】兵团农田钾肥的施用要有选择性,钾肥应该优先施用在喜钾作物和沙性缺钾的土壤上。

摘  要:
【Objective】In order to improve the output efficiency of potassium in farmtand soil,the management of potassium of farmland soil in Corps will be strengthened.【Method】Based on the second general soil survey in Corps,this papaer analyzes the change of the potassium in farmland soil and the potassium input in farmland soil during twenty years.【Result】Analyzed the reason of the potassium content reduce in Corps farmland soil and the reason of the yield increase when potassium application.Although the potassium content is reduced in Corps farmland soil,but it is highter than that compared with the countrywide.Applying the potassium excessively and unreasonable,the result of the cost will the higher and the output efficiency lower.【Conclusion】When the potassium is applied,it must be selective,and should be used on the like-potassium plant and the sand-soil
