苜蓿改良的盐碱土壤施肥对小麦的效应研究—I.对小麦生长及产量的影响

Effect of fertilizer on wheat in saline soil improved by alfafa--I. Its effect on the growth and yield of wheat

  • 摘要: 盆栽试验和大田试验结果表明,苜蓿改良的盐碱土壤仍以施N肥对小麦的增产作用最明显,盆栽小麦可增产61.2%,相对叶重增加16.2%,穗粒教增加37.36%,穗粒重增加10.3 %;施P肥小麦增产l6.78%,穗粒重增加8.39%,怛对穗粒教影响较小;施K肥效果不明显;NP结台施用小麦增产74.76%.大田试验拖N肥小麦可增产60%;NP结合施用小麦增产73.5%.施N补P是苜蓿改良的盐碱土壤作物增产的关键,也是该类地区的共性问题。

     

    Abstract: Pot and field experiments were conducted in Nanpi Eeo-agricultural Experiment Station, CAS,from 1995 to 1996.The results show that in saline sol1 ireproved by alfafa,application of N can increase grain yield of wheat by 61.2%,relative leaf weight by 16.2%,grain number by 37.36%.grain weight by 10.3 in pot experiment.Under the conditions of P application,grain yield increased by 16.78%,grain weight by 8.39%,but there is no effect on the grain number.Application of N and P could increase grain yield by 74.76%.But K is almost no effect on the growth.biomass and yield of wheat.Application of N and NP could increase yield by 60% and 73.5% respectively.Application of N and P is the key to iocrease crop yield in saline soil improved by alfafa,which is also the key to get high crop productivity in this region.
