Study on Rational Fertilizing Technology for Asparagus in Chongming

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／667m^2；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。

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 667m^2 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.
