针对辽西朝阳县的干旱气候特点,研究出提高朝阳大枣(Ziziphus jujuba Mill.)植苗造林成活率新技术,即“两埋一提苗”浇水造林新技术,与一般浇水造林技术的主要区别点在于减少了“一埋和两踩”工序。结果表明,新技术可使大枣植苗造林平均成活率达到91%以上;平均提高当年新生枝生长量133%;降低造林成本3 200元/hm2。
According to the characteristics of arid climatic conditions in Chaoyang County of western Liaoning Province, a new technology to improve the survival rate of Ziziphus jujuba Mill., Ie “two burial and one seedling afforestation”, has been developed and compared with the common watering and afforestation techniques The main difference is the reduction of “one bury and two treads” process. The results showed that the new technology can make jujube plantation afforestation average survival rate of 91% or more; the average annual increase of 133% of the new branch growth; reduce the cost of afforestation 3 200 yuan / hm2.
