摘  要:
以甘蓝型绿肥油菜新品种油肥1号为试验材料,研究绿肥油菜种植对土壤养分以及鲜食玉米生物学特性、产量的影响.结果表明:绿肥压青后,土壤养分明显改善,速效磷和有机质含量分别比冬闲处理提高2.72%和9.78%;绿肥油菜压青能够提高鲜食玉米果穗行粒数,改善顶部结实,减少秃尖;绿肥油菜压青后,采取常规用量或减施5%的化肥时,玉米产量分别较对照增产9.29%和8.07%,差异达到极显著水平;而减施10%~15%的化肥时,鲜食玉米产量与对照相当.

摘  要:
This study utilized a new type of green manure variety of Brassica napus Youfei NO. 1 to analysis the effect of the growth of fertilizer rape on the biological characteristics and yield of fresh corn and soil fertilizer. The results showed that after green manuring, the soil nutrient significantly improved, available phosphorus and organic matter content were increased by 2.72% and 9.78% than fallow treatment in winter; green manure rape can improve the grain number of fresh corn, improve the top fruit and reduce the bald tip; after green manure application, the yield of maize increased by 9.29% and 8.07% compared with the control of conventional or 5% of reduced fertilizer, and the difference reached a very significant level; when the 10%-15% fertilizer was reduced, the yield of fresh corn was equal to that of the control.
