【摘要】 根据绿芦笋的不同肥料品种、不同施肥量和施肥方式试验对芦笋产量的研究。结果表明:缓释肥料在减氮20%条件下,仍能获得比对照高7.9%的产量;通过各元素间的平衡施肥,比对照节本增收154.9元/667m2;叶面喷施复合微肥可提高产量6.86%~8.25%,取得了较好的经济和生态效益。更多还原

【Abstract】 In this paper,different kinds of fertilizers,different fertilizer application amounts,and different fertilizer application ways were studied the effects on the Asparagus yield.It demonstrated that yield increased 7.9%,although the N content of the slow-realease fertilizer decreased 20%.The Asparagus production profit increased 154.9 yuan per 667 m2 with equilibrium application fertilizer of various elements.The yield increased 6.86%~8.25% when leaf-surface spraying trace element fertilizers,achieving good economic benefit and ecological benefit.更多还原
