摘要
通过田间试验设计研究不同基质(A)、不同基肥(B)及不同种类追肥(C)对卷荚相思组培苗移植到圃地营养袋培育至出圃时的成活率、苗高的影响差异。结果表明,使用红心土∶发酵过木屑∶炭化谷壳=6∶2∶2作为移植基质(A1)+3 kg.m-3硫酸钾复合肥作为基肥(B2)+0.4%高钾型高乐和磷酸二氢钾作为追肥(C2)时效果最好,平均成活率达86.3%,平均苗高达16.8 cm。
Through field test design, the effect difference of survival rate ＆ seedling height of Acacia cincinnata which were transplanted to the nutritional bag in the nursery by using different matrix （A）, different base fertilizer （B） and different topdressing type （C） were studied. The result indicates that ：taking the red subsoil： fermented sawdust： carbonized hull = 6：2：2 （A1） as the transplanting matrix, taking 3 kg·m^-3 potassium sulfate compound （B2 ） as base fertilizer, taking 0. 4% high-potassium type Gaole ＆ potassium dihydrogen phosphate as topdressing （C2 ）, the effect is the best, with the average survival rate being 86.3%, average seedling height being 16.8 cm.
