菌糠泥炭复合基质对树豆育苗的影响

摘要

Variously formulated substrates using the discards from mushroom cultivation (MCD) and peat were tested on plug trays to grow seedlings of 3 varieties of Cajanus cajanfor the selection of an optimal mixing ratio for the combination medium.It was found that a mixture containing no more than 50% of MCD would promote the increases on the height and girth of the stems, as well as the accumulated dry matters of the seedlings.In the recommended substrate of 1 part of MCD and 3 parts of peat, the Cajanus cajan seedlings sustained significantly higher length and diameter of the stems, as well as dry matter and chlorophyll contents than control, which contained peat and perlite in 3 to 1 ratio.%以不同体积比的菌糠泥炭复合基质,开展3种树豆品种的穴盘育苗试验,结果表明:菌糠泥炭复合基质用于树豆育苗,菌糠体积比低于50%时有利于树豆出苗率的提高,株高、径粗的生长以及干物质量的积累;且当菌糠∶泥炭=1∶3时,3种树豆出苗率、株高、径粗、干物质量以及壮苗指数等指标均极显著高于对照处理(珍珠岩∶泥炭=1∶3).因此建议树豆穴盘育苗基质配方采用菌糠∶泥炭=1∶3.
