摘要
为探究不同地膜覆盖与施肥方式对白魔芋生长的影响,试验设置3种不同颜色地膜(双色膜、白膜和黑膜),以及对照(不覆膜),再结合两种施肥方式(水肥模式和传统模式),共8组处理.结果表明:①双色地膜能够减少田间66.59%的杂草数量,提高光照强度,其中壮苗指数、叶绿素质量比和产量相较于对照组分别增加了40.7%,38.1%和43.3%;②在不同地膜覆盖下水肥管理施肥方式相较与传统施肥方式产量分别提高了22.2%,24.0%,15.4%和15.1%.
In order to explore the effects of different film mulching and fertilization methods on the growth and development of white konjac(Amorphophallus albus),a test was made,in which 4 modes of mulching(two-color film,white film,black film and no film)were combined with two fertilization methods(water and fertilizer mode and traditional mode)to form a total of eight treatments.The results showed that compared with the no-mulch control,two-color mulch reduced the number of weeds in the field by 66.59%and increased the light intensity,and its seedling index,chlorophyll content and yield increased by 40.7%,38.1%and 43.3%,respectively;and that compared with the traditional fertilization method,the water and fertilizer mode adopted in this test,gave a yield increase of 22.2%,24.0%,15.4%and 15.1%,in the 4 modes of mulching.
