摘要
通过正交试验表明,在天水浅山半干旱地区,采取鱼鳞坑工程整地和定植区薄膜覆盖蓄水保墒,苗木根系保湿醮根处理,花椒造林成活率可达到98%,第2年新梢平均最长生长量在45 cm以上,分别比一般造林提高30.7%和21.6%;并且提前2～3年挂果受益,第5年平均单株花椒产量在2kg以上。
Through the orthogonal test indicated that in semiarid regions nearby mountains of Tianshui,adopt-ed the scale pit project preparation of soil and cover thin film to storage preserving soil moisture at planting area,the nursery stock root system moisturizer ferments root processing,the survival rate of forestation of Zanthoxylum bungeanum can achieve 98%,in the following year,the longest average growth quantity of new tree top was above 45 cm,improved 30.7% and 21.6% separately compared to the common forestation;And 2～3 years bear fruit a-head of time and gain profit,in the fifth year,annual mean single output of Zanthoxylum bungeanum was above 2 kg.
