补充资料：杨树速生丰产林平衡施肥技术
1．施肥量。杨树施肥量的确定，除考虑杨树本身的需肥规律及造林地土壤养分条件外，还应综合考虑杨树品种、树龄、林分密度及地下水位等因素的影响。一般在我省杨树主产区，每亩可施尿素40公斤，过磷酸钙60公斤，氯化钾30公斤。此外，还必须根据土壤分析结果，加施必需的中、微量元素养分。
2．施肥次数。杨树施肥以每年4-5月，7-8月两次施肥效果较好，每次分别施入全年施肥量一半的肥料。
3．施肥方法。采用四点穴施的方法，根据杨树树龄的大小，在根系分布的范围内，于杨树周围均匀挖穴四个，将肥料平均施入后覆盖。施肥深度依据不同树龄以15-30厘米左右为宜。（来源：湖北林业2003年第7期）
