摘要
通过对西南桦种子两种不同播种时期育苗的对比 ,发现秋季播种的一年生苗木比即采即播的一年生苗木的高生长、地径生长、主根长和侧根数分别提高 5 7.1 %、3 9.5 %、1 8.5 %和 2 3 .0 % ,避开了炎热夏季 ,根际病害感染程度比即采即播苗木减少 88.1 % ,苗木质量显著提高 。
Two treatments of sowing and cultivating Betula alnoides Buch-Ham were studied. The results showed that the height,diameter above ground,main roots length increment and the fine root numbers of seedlings sowed in autumn were respectively 57.1%,39.5%,18.5% and 23.0% higher than seedlings sowed instantly after their collection. Because the seelings sowed in autumn avoided fervent summer,their infection rate of rhizomatic disease was decreased by 88.1% and the quality of seedlings was improved evidently. The cultivation managements at each stage were brought forward.
