2个紫花苜蓿品种在成都平原生长特性研究

Research on growth characteristics of two alfalfa varieties in the Chengdu Plain

为了探讨紫花苜蓿(Medicago sativa L.)品种在成都平原的生产性能,采用田间小区试验的方法,对紫花苜蓿凉苜1号(Medicago sativa L.liangmu No.1)和WL525(Medicago sativa L.WL525)2个品种于2016~2019年进行试验研究.结果表明:紫花苜蓿在该地区种植,播种当年(2016年)无产量,翌年可刈割7~9次,能实现全年供应鲜草,2017年产量达到最高,其鲜草产量平均达123.21 t·hm^(-2),干草产量达21.77 t·hm^(-2),从2018年开始草产量逐年下降,2个品种变化趋势一致.总之,2个紫花苜蓿品种草产量高,适宜在成都平原推广利用.

In order to study the production performance of alfalfa(Medicago sativa L.)in Chengdu Plain,two varieties of liangmu No.1 alfalfa(Medicago sativa L.liangmu No.1)and WL525 alfalfa(Medicago sativa L.WL525)were tested from 2016 to 2019.The results showed that when alfalfa was planted in this area,there was no yield in the sowing year(2016),and it could be cut 7~9 times in the next year,which can realize the supply of fresh grass throughout the year.The yield reached the highest in 2017,with the average fresh grass yield of 123.21 t·hmand hay yield of 21.77 t·hm.Since 2018,the grass yield has decreased year by year,and the change trend of the two varieties was the same.In conclusion,the two alfalfa varieties have high grass yield and are suitable for popularization and utilization in Chengdu Plain.
