平茬对北方地区巨菌草生长的影响研究

为了了解平茬对北方地区巨菌草的影响,以内蒙古呼和浩特市土默特左旗温室大棚内巨菌草为研究对象,根据巨菌草的生长周期设置了平茬前为对照组,平茬一次后共两种处理方法的实验,分析了平茬前后巨菌草生长状况的变化。结果表明:与未平茬相比,平茬处理后巨菌草的生长速度明显增加,包括株高,叶片数,基部直径;其中分蘖形成的数量也大于未平茬时的分蘖数量;平茬后生物量显著高于未平茬的生物量。可见,平茬处理改变了巨菌草的生长速度、增加了巨菌草的分蘖数量;提高了巨菌草的生物产量。

Effects of Before and After Flat Stubble on the Growth of Giant Fungus in the Northern Areas

In order to understand the influence of flat stubble on Giant Fungus in northern areas,this paper takes the Giant Fungus in the greenhouse in Tumotezuo Banner,Hohhot,Inner Mongolia as the research object.The experiment sets the control group before flat stubble according to the growth cycle of giant grass.In the group,there are two treatment methods after one flat stubble,and the changes in the growth status of the Giant Fungus before and after flat stubble are analyzed.The results showed that the growth rate,including plant height,leaf number and base diameter,was significantly increased after the treatment.The number of tillers formed was also greater than that of tillers formed before flat stubble.Biomass after flat stubble was significantly higher than that before stubble.It can be seen that the flat stubble treatment changes the growth rate and increases the number of tillers.The biological yield of Giant Fungus is increased.
