【摘要】 对紫花苜蓿进行微肥喷施试验,结果显示:喷施微肥能显著提高其草产量,其M2C2处理草产量增幅最大,达到38.22%;并能促进其干鲜比的增加,其M2C1处理干鲜比最大;且对其叶茎比也有显著影响,其M1C1处理叶茎比最大,而M2C2处理叶茎比最小。更多还原

【Abstract】 The experiment of spraying trace elements on Medicago sativa was carried out during growth.The results showed that the yield of dry forage was remarkably increased,the most amplitude Treatment of dry forage is M₂C₂ for 38.22%;the proportion of fresh-forage yield to dry-forage yield（FD） was also incremented,the most Treatment of FD is M₂C₁ and the leaf stem ratio（LS）was observably affected,the most Treatment of LS is M1C1,the least Treatment of LS is M₂C₂.更多还原
