【摘要】 对龙 94 - 40 83强筋小麦需肥特性及施肥对小麦产量和品质的影响进行了研究。结果表明 ,龙 94— 4 0 83小麦养分吸收量前期少 ,中、后期迅速增加 ,并有两个吸收高峰。一是从三叶期到孕穗期 ,二是从灌浆期到成熟期。在三叶期小麦植株养分吸收量最少 ,成熟期最多 ,而且对氮和钾的吸收量远远大于磷。氮、磷、钾平衡施肥既增加了小麦产量 ,又改善了小麦品质。更多还原

【Abstract】 This paper deals with the characteristics of the nutrient requirement of wheat Long 94-4083 and the effect of different fertilization on the yield and quality. The result showed that the amount of nutrients uptaked by the plants was less during the early stage and the most at the maturing stage. The amount of nutrients assimilated by the wheat had two peaks. One was at the stage of booting, the other was at the stage of maturing. Nitrogen and potassium were required much more by the wheat plants than phosphorus. Through balanced fertilization with N, P and K, the yield increased and the quality improved.更多还原
