摘 要:以银缕梅为材料,设置不覆盖(对照)、塑料拱棚、白色地膜覆盖、秸秆覆盖4个处理,测定各处理下银缕梅苗高、地径和各生物量,分析不同覆盖方式处理的效果。结果表明:白色地膜覆盖的根、茎、叶及总生物量较对照分别高212.5%、121.9%、108.8%、156%,保温作用最好,最适合于银缕梅的生长发育。Effects of mulching methods which were control(CK),arch shelter,plastic film mulching,straw mulching respectively,were studied by Parrotia subaequalis seedlings according its height,ground diameter and biomass. Re. sults showed that seedlings ground diameter was the maximum at plastic film mulching,however,there was no signifi. cant difference;biomass of root,stem,leaf and total seedlings was higher 212.5%,121.9%,108.8% and 156.0% com. pared with CK respectively;according to soil temperature,plastic film mulching kept warming better;soil water con. tent was higher at three mulching methods at March and April,however,it lower at May and June.
