【摘要】 通过多年盆栽和田间小区试验,研究了淮北平原砂姜黑土区小麦锌氮配施效应及对土壤有效锌氮含量和后作大豆的残效。结果表明,配合锌氮肥施用对小麦生长发育有明显的促进作用,能有效增加小麦体内干物质的积累量,显著提高小麦植株含锌含氮水平,积累更多的锌和氮,改善经济性状,具有显著的增产效果。盆栽小麦增产9.26％～16.8％,大田小麦平均增产率为7.15％～13.8％。土壤有效锌含量提高65.1％～96.2％,碱解氮含量升高8.45％～38.9％,对后作大豆具有明显的残效作用。盆栽大豆增产9.73％～25.7％,田间试验增产6.72％～16.6％。更多还原

【Abstract】 Pot and field experiments were conducted for several years in the shajiang black soil located in the northern part of the Huai River. The results showed that applying nitrogen in conjunction with zinc had obviously promoted the growth of wheat.It had increased the accumulation of dry matter,and the contents of zinc and nitrogen in wheat notably raised.It could accumulate more zinc and nitrogen,and improve economic returns and quality.The effect of increasing product was remarkable.Winter wheat planted in pot increased product of 9.26 - 16.8 percent, and the average rate of growth of wheat cultivated in field were 7.5% -13.8% .The contents of available Zn in soil improved by 65.1% - 96.2%, and alkaline hydrolysable N 8.45 - 38.9 percent.lt had good effect on the subsequent soybean of next season.The yield of soybean planted in pot was increased by 9.73 - 25.7 percent,and cultivated in field.7.72% - 16.6%.更多还原
