不同施氮量对荆杂棉88生长及产量的影响

Effects of Different N Application Rate on the Growth and Yield of Jingzamian88

为探讨施氮量对杂交棉荆杂棉88的生长及产量的影响。试验设计5个施氮量对荆杂棉88农艺性状和产量的差异比较。结果表明,施氮量对荆杂棉88的农艺性状和产量均有影响,在一定的氮肥施用量范围内,单株成铃、铃重、产量会随着施氮量的递增而递增,当氮肥施用量超过一定的范围,则会随着施氮量的递增而下降。说明合理施氮可通过影响棉花的生长而提高产量,达到高产高效的目的。

The test compared the differences of agronomic traits and yield of Jingzamian 88 through designed five N application rates on Jingzamian 88.The results showed that, in a certain range of nitrogen fertilizer, the bolls per plant, boll weight, yield increased with the increasing amount of nitrogen, when the nitrogen application amount exceeds a certain range, then decreased with the increment of nitrogen application the amount. It explained that, reasonable nitrogen could achieve the goal of high yield and efficiency through influencing cotton growth and increasing yield.
