摘要
研究了不同施肥处理对续随子生物产量及经济产量的影响。结果表明,在供试土壤肥力基础上,氮肥的供应是续随子产量形成的主要限制因子,施用氮肥可显著增加续随子生物产量及经济产量;氮肥配施钾肥的增产效果优于配施磷肥;不施氮肥而单施磷、钾肥对提高续随子产量效果不大。
Effects of different fertilizer treatments on biological and economic yield was preliminary studied in caper spurge. The results showed that N fertilizer supply was a major limiting factors on caper spurge yield, and the treatments containing N fertilizer could significantly increase biological yield and as well as economic yield compared to the treatments without N fertilizer.The effects on yield in the treatments containing N＋K fertilizer were better than that containing N＋P fertilizer;The effects on yield were not distinct in the treatments only containing P or （and） K fertilizer but no N fertilizer.
