【摘要】 通过对蒙古栎直播造林、植苗造林的试验研究,结果表明:直播造林,蒙古栎的生长量较小,受晚霜危害严重;植苗造林要以栽植1年实生苗,选择具有一定上层木、郁闭度在0.2左右、坡度在10°左右山的中上腹造林最佳。植苗造林喷施叶面肥可提高生长量27%;修枝可提高生长量11%以上。更多还原

【Abstract】 Through the direct seeding and afforestation by transplanting seedlings experiments of Quercus mongolica,the results show that the growth of direct seeding is little,being hurt by late frost.Taking the method of afforestation by transplanting seedlings,on the middle and upper part of the mountain with the slope being about 10°and canopy density 0.2 are the optimum selection.Taking afforestation by transplanting seedlings,fertilizing and prunning can increase the growth by 27% and 11%.更多还原
