【摘要】 本试验以百合科葱属野韭、沙葱、薤白、细叶韭4种植物为试验材料,2007年4月20日同时播种于内蒙古农业大学科技园区,次年观察植株的萌动期、叶片、株高生长动态。其结果表明:1、野韭、薤白和细叶韭在3月上旬先后陆续萌动,沙葱在3月中旬开始萌动,比野韭晚6d,比细叶韭和薤白晚9d~10d;2、沙葱、薤白、野韭、细叶韭4种植物单株平均总叶片数分别为94片、46.1片、18.5片、14.4片;3、野韭和细叶韭月平均新生叶片数占总叶片数的百分比在6月份达到最大值,分别为36.2%、49.1%,而沙葱和薤白是在7月达到最大,分别为36.0%、33.8%;4、葱属4种植物植株5月~7月每新增1片新叶所间隔的天数不同,沙葱为0.9d~2.1d;薤白为2.0d~2.5d;野韭为4.5d~11.9d;细叶韭为2.7~25.8d;5、野韭和薤白在7月后已停止生长,沙葱和细叶韭在8月停止生长;其平均单株高度顺序为野韭>薤白>细叶韭>沙葱。从月平均新增高度占总高度的百分比来说,野韭和细叶韭在5月株高增长最快,薤白在6月株高增长最快,沙葱在7月增长最快。更多还原

【Abstract】 The materials were Allium ramosum L.、Allium mongolicum Regel.、Allium macrostemon Bunge、Allium tenuissimum L.,which were sowed seeds in sci-tech park of Inner Mongolia Agriculture University on April 20th,2007,and were observed their sprout period,leaf number,plant height at second year.The results showed that: 1、A.ramosum L.A.macrostemon Bunge and A.tenuissimum L.sprouted on the first ten days of March,A.mongolicum Regel sprouted on the middle ten days of March,was later six days than A.ramosum L.was later nine days or ten days than A.macrostemon Bunge and A.tenuissimum L.2、The leaf number of A.mongolicum Regel was 94,A.macrostemon Bunge was 46.1,A.ramosum L.was 18.5,A.tenuissimum L.was 14.4.3、The percentage of neonatal leaves and total leaves of A.ramosum and A.tenuissimum L.was maximal on June,was 36.2% and 49.1%,but others were on July,and were 36% and 33.8%.4、The distant days of new increased leaf of A.mongolicum Regel was from 0.9 to 1.2 d,A.macrostemon Bunge was from 2.0 to 2.5 d,A.ramosum L.was from 4.5 to 11.9 d,A.tenuissimum L.was from 2.7 to 25.8 d,5、A.ramosum L.and A.macrostemon Bunge stopped growing on July,but Allium mongolicum Regel and A.tenuissimum L.stopped growing on August.6、The plant height of A.tenuissimum L.and A.ramosum was fastest on May,A.macrostemon Bunge was on June,A.mongolicum Rege was on July.更多还原
