摘　　要：通过安排田间小区试验,研究了金银花生长前3年,夏季修剪和冬季修剪对金银花早期产量和生长的影响。通过分析,夏季修剪对地径增粗的影响较小;在金银花定植的第1年,进行过重的夏季修剪不仅不能增加地径粗度,反而有相反作用,冬季修剪对地径增粗影响显著,即冬季修剪可使金银花主干增粗。相对于不修剪,较轻的夏季修剪和冬季修剪均可显著提高"九丰1号"金银花植株高度,减少发枝数并缩减冠幅;相对于轻剪,较重的修剪使树体被过度削弱,使株高降低、发枝数减少。夏季修剪和冬季修剪均对产量有影响,但冬季修剪对产量的影响更显著,在金银花定植早期(第2年)修剪会使金银花产量降低,且重剪降低程度甚于轻剪,但是当植株生长到第3年,合理的修剪可有效增加金银花产量,且三年产量总和最高。研究表明,金银花早期最为合理的增产修剪方案为冬季轻剪和夏季轻剪处理。In this paper,through the arrangement of field plot experiment,the first 3 years of growth of Lonicera Japonica Thunb.,studies the influence of post flower removing and pruning in winter on the early growth and yield of Flos lonicerae.Through the analysis,post flower removing has little effect on the ground diameter,in the first year of honeysuckle colonization were heavy post flower removing can only increase the ground diameter,but have opposite effects,on the basis of a certain growth,winter pruning can make the honeysuckle trunk thickening. Compared with the no pruning,light post flower removing and pruning in winter could significantly increase the Jiufeng 1 honeysuckle plant height,branch number and reduced crown reduction; compared with light pruning heavy pruning make the tree body weak,decrease the plant height,reduce branch number. Post flower removing and pruning in winter have effect on yield,but the influence of winter pruning on yield is more significant,in Flos Lonicerae planting early（ second years） pruning makes honeysuckle production decreased,but when the plants grew to third years,reasonable pruning could effectively increase the yield of Flos Lonicerae Japonicae,and three year yield the highest sum.In this paper the honeysuckle early yield pruning scheme is reasonable for winter gentle pruning and summer light pruning.
