不同施肥处理对苜蓿生长特性的影响研究

Studying Influence of Different Fertilizer Treatments on Alfalfa Growth Characteristic

在金华地区酸性红壤土上对紫花苜蓿进行不同施肥处理的对比试验,结果表明:每667 m2施用80 kg复合肥,生长速度最快,在各阶段植株最高,鲜草产量也最高,与不施肥的对照组比较差异显著(P<0.05);而从综合指标来看,每667 m2施用40 kg复合肥、600 kg有机肥,其株高、鲜草产量和蛋白质含量均较高,且第2年的长势较好,可作为进一步试验或实际应用的施肥参考方案。

Carrying the contrast experiment of the different fertilizer treatments on Alfalfa in Jinhua acid red loam, the results indicate that, each 667m^2 is employed the 80kg Fertilizer compound, the growth speed of the treatment is quickest, the plant is highest in various stages, the fresh grass output is also highest, comparing with control group which is not applied fertilizer, the both is remarkable （P〈O.05） ; while, according to synthetic indexes, each 667m^2 is employed the 40kg Fertilizer compound, 600kg organic Fertilizer, the plant height and the grass output as well as protein content is relatively higher, moreover, In the next year taken further experiment or practical application as the growth potential of the treatment is better. Therefore, it may be fertilizing reference proposal.
