摘要
本文结合造林生产,对采用低温假植核桃苗木延迟造林时间至4月20日后的造林结果进行了调查分析,结果表明:采用低温假植核桃苗木延时造林措施,其当年平均造林成活率可达到91.0%以上,枯梢平均长度为24.5cm。核桃嫁接苗品种芽平均萌枝长度为60.7cm。且工序简单,适宜春天造林。
Afforestation was deferred until April 20 after heeling in. The effect of afforestation was in- vestigated. The result showed that measures achieved better survival rate at 91.0%, with dry shoot length at 24.5cm and germinated shoot length at 60.7cm. The process is simple and easy to applied in Spring afforestation.
