摘要:
为了科学合理地施用磷肥，通过施用不同数量磷肥研究其对大豆生长状况的影响。结果表明：磷肥对大豆株高和叶绿素的影响差异不明显；对大豆植株干物质积累的影响主要表现在盛花期和鼓粒期，NP3K(N 10.13 kg·hm-2，P2O5?77.63 kg·hm-2，K2O 60 kg·hm-2)和NP2K(N 10.13 kg·hm-2，P2O5?51.75 kg·hm-2，K2O 60 kg·hm-2)处理与NP1K(N 10.13 kg·hm-2，P2O5?25.88 kg·hm-2，K2O 60 kg·hm-2)处理相比均达到了显著水平；盛花期根瘤数和根瘤干重随着施磷量的增加而增加。固氮酶活性NP2K处理最强，能够显著增加大豆单株荚数、单株粒数和百粒重，得到较高的产量，并改善大豆产量性状。
Abstract:
In order to scientifically apply phosphate fertilizer,effect of different amounrs of phosphate fertilizer on soybean growth was researched.The results showed that phosphate fertilizer sould significantly influence on soybean plant height and chlorophyll differences.On soybean dry matter accumulation were studied mainly in the flowering and podding stage,NP3K(N 10.13 kg?hm-2，P2O577.63 kg?hm-2，K2O 60 kg?hm-2) and NP2K(N 10.13 kg?hm-2，P2O551.75 kg?hm-2，K2O 60 kg?hm-2) treatments compared with NP1K(N 10.13 kg?hm-2，P2O5 25.88 kg?hm-2，K2O 60 kg?hm-2) treatment were significant.The number and dry weight of nodules with the increasing phosphorus application amount increase.The strongest nitrogenase activity of NP2K was the best.The phosphorus fertilizer could significantly increase the pod number per plant,grain number per plant and 100 grain weight,get higher yield,and improve the yield trait of soybean.
