- 摘要:
- 试验结果表明,不同处理的春小麦各生育期的氮磷吸收趋势是一致的.植株的氮素相对含量苗期最高,抽穗期最低,灌浆期逐渐提高,每个时期与对照几乎相同.而绝对含量各时期是逐渐上升的,且明显高于对照;植株磷素相对和绝对含量苗期最低,拔节期急速上升.不同处理的相对含量与对照接近,绝对含量明显高于对照;同时,合理施用氮肥,不仅能促进磷素的吸收,而且能促进土壤磷的释放,改变土壤磷的形态.通过F值测定,不同氮肥品种间产量差异不显著.氮磷配合处理间差异极显著.且以尿素和硫铵组合的处理增产效果最佳.同时,在人工灌溉条件下,施肥各
- Abstract:
- Using different fertilizer treatments,the absorptional trends of Spring wheat to nitrogen and phosphorus were same,and the relative nitrogen content of the crop were highest,lowest and gradually inreasing during seedling,heading and grain filling stage respectively,and at each stage the trends were approximately same as the control,although the absolute nitrogen content at each stage was increased gradually and was obviously higher than the control.The relative and absolute phosphorus contents of the crop were lowest at the seedling stage,and then sharply increased at the jointing stage.Among different treatments,the relative phosphate contents were similar as the control,but absolute ones were higher than control,at meantime,rational application of N nutrition was able not only to promote the phosphate uptaking but also to increase the phosphate release and to change the phosphate states in soil.By the F value of the statistic test,the productional differences among the different fertilizer treatments were not obviously,but among the nitrogenous and phosphate combining treatments,the F value were very significant,and the best result to increase productivity,was the urea and ammonium sulphate combining tratment,also,under the controlling irrigattional conditions,water use effeciencies among all kinds of fertilizer treatments became more higher.
