摘要
采用混料回归试验设计,利用拟合的回归模型计算,以红心土为54.09%,谷壳为0.2%,砂子为0.35%,珍珠岩为40.41%时,其理论生根率可达到98.63%,与实际试验中7号配比在基质成份(即红心土45%+珍珠岩55%)上非常接近。西南桦各个月份扦插的对比实验结果表明,以春季为最佳的扦插季节,平均生根率达90%以上。
Through using simplex core experimental design, by fitting regression model the medium can calculate with 54.09% red soils,ehaff 0.2%,grit 0.35% ,pearlier 40.41%, theoretically, the spout rating was up to 98.63% in cutting of BetuIa alnoides. This result is similar to seventh group in practical trial. The research had already accomplished the trial of cutting of Betula alnoides in different month. The result show： the best rooting month is spring, average rooting rate is up to 90%.
