查询词典 soils

An experiment on artificial soils consisting of peat , sand and cooking coal ash suggests that the optimum ratio of peat and sand lor best growth and fertilizer efficiency is 75:25 or 50:50 in volume for Chrysanthemum and Tagetes erecta .

用泥炭、河砂和煤渣分别组成花卉营养土的试验表明，泥炭与河砂以75∶25或50∶50容积比例组成的基质对黄菊和万寿菊的效果最好，肥料效率也最高，煤渣的效果明显低于河砂；从组分的细度看，河砂以粒径2—0.15mm最好，煤渣在使用前除去过细部分会大大提高其利用价值。
