不同施磷量对豌豆生长发育及产量性状影响初探

Preliminary Study on Effect of Different Phosphorus Applilcation on Yield Character and Growth in Pea

[目的]确定豌豆最适施磷量,为豌豆配方施肥提供科学依据。[方法]以中豌6号为供试豌豆品种,通过不同磷素水平对豌豆生长发育及产量性状的影响,确定豌豆的推荐施肥量。[结果]豌豆最适施磷量为60 mg/株。[结论]磷肥对豌豆的生长发育以及产量影响明显,适当增加磷肥的施用量可以提高豌豆的产量。

[Objective]The optimal quantity of phosphorus application on pea was determined and scientific basis for the formula fertilization was provided. [Method] Taking Zhongwan 6 as the test variety, the recommended fertilizer amount of pea was determined by using different phosphorus application on growth and yield.[Result] The pea optimal phosphorus amount was 60 mg per plant.[Conclusion] The effect of phosphorus was significant to growth and yield of pea. And appropriately increasing the application amount of phosphorus could improve the yield of pea.
