| 摘 要： | 本文通过对不同坡向、不同覆土厚度 ,春秋两季臭椿直播造林的成活率进行了对比调查 ,结果表明 :秋季直播造林 ,阴坡比阳坡、半阴坡成活率高。覆土 4 比覆土 2 、 6 的效果好。春季直播造林 ,阴坡比阳坡、半阴坡成活率高 ,覆土 6 比覆土 2 、 4 的成活率高。春、秋两季直播造林相比 ,秋季比春季成活率高。

| Abstract: | This paper is mainly on the comparison of %Ailantus altissima(Mill) swingle% direct seeding afforestation in spring with that in autumn, different hillside directions and various covering soil depths.The results show: 1)Direct seeding afforestation in autumn, it will more effective if seeding in shady hillside than that in sunny and semishady hillside; Govering soil of 4 centimeter is more effective than 2 centimeter and 6 centimeter. 2) Direct seeding afforestation in spring the survival rate is higher in shady hillside than that in sunny and semishady hillside; Covering soil of 6 centimeter gets a higher survival rate than 2 centimeter and 4 centimeter. 3) Direct seeding afforestation in autumn gets a higher survival rate than in spring. |
