摘要: 在田间条件下,研究了氮、磷、钾肥料不同配比对春小麦生长和产量的影响。结果表明,氮、磷、钾肥配合施用对小麦生长及产量均有促进作用。在施肥的六个处理中,处理2(N:P2O5:k2O=6:8:3)的小麦生长具有明显的优势,表现为小麦各生育时期干物重、叶绿素含量增加,硝酸还原酶活性(NRA)及籽粒含氮量较高,与产量有关的性状如:穗长、小穗数、穗粒数、穗粒重及干粒重等得到明显改善,籽粒产量最高,比对照增产742.6kg /hm2,增产率为18.8%,小麦品质也表现较好,蛋白总量高达804.7 kg/hm2。

Abstract: The field experiment was conducted to study the effect of fertilizers N, P, K cooperation on spring wheat growth and yield. The results indicated that fertilizers N、P、K cooperation could promote spring wheat growth. The treatment 2 (N:P2O5:K2O =6:8:3) was most effective among the six fertilization treatments. This showed that wheat dry matter weight and the content of chlorophyll was increased, the activity of NRA and the N content of grain was higher, The character correlation of yield (length per spike, grains per spike, 1000-grain weight)was marked amelioration, the grain yield was highest and was increased 742.6kg/hm2, the rate of increased yield was 18.8%, the quality was good and the content of protein was 804.7kg/hm2.
