不同施氮措施对保护地黄瓜养分利用效率及土壤氮素淋失影响

Shuitu Baochi Xuebao, 2007
不同施氮措施条件下，对保护地黄瓜生育期内氮素吸收利用效率、氮素淋洗损失进行了研究，同时也研究了不同处理对黄瓜产量及品质的影响。试验结果表明，传统施肥处理（2100kg／hm^2）与推荐施肥处理（900kg／hm^2）之间氮素吸收量没有显著差异，传统施肥处理中大量的氮肥没有用于促进黄瓜对养分的吸收利用，其氮肥利用率、农学利用率以及生理利用率都很低，每千克纯氮增产只有2．06kg，91．65％的氮素以各种途径被损失掉，其中土壤硝态氮淋洗是主要形式。同时研究发现，传统施肥处理过量氮肥施用阻碍其它营养元素的吸收，
