摘要
本文研究了江南桤木不同播种量和不同水分管理方法的育苗效果。结果表明,播种量以45kg/hm2量为宜,苗木高生长、地径生长和优质苗产量均优于其他几种处理方法;水分管理以"湿管法"育苗效果最好,苗木的高生长、地径生长和优质苗产量与"水管法"、常规育苗方法间均存在显著差异。
In this paper the seedling-raising effects of different sowing rates and water management methods were studied. The results indicated that the sowing rate of 45 kg/hm2 was the most suitable with the biggest height and basal increments of the seedlings and quality seedling output among all the sowing rates, and the moisture-keeping method was better than the water-keeping method and regular seedling-raising method with significantly bigger height and basal increments and quality seedling output.
