- 摘要:
- 对龙94 -4083 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 —4083 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。
- Abstract:
- This paper deals with the characteristics of the nutrient requi rement of wheat Long 94 - 4083 and the effect of different fertilizat ion on the yield and quality .The result showed that the amount of nutrients uptaked by the plants w as less during the early stage and the most at the maturing stage .The amount of nutrients assimilated by the w heat had two peaks .One w as at the stage of booting , the other w as at the stage of maturing .Nit rogen and potassium were required much more by the w heat plants than phospho rus .Through balanced fertilizat ion with N , P and K , the yield increased and the quali ty improved .
