摘要
为选育出适应黑龙江省气候条件的平原杨树优质速生纤维林新品种(系),有目的选配杂交组合,获得14个杂交种。初步选择种子饱满、种量大、杂种苗生长状况好的5个杂交组合,可望在试验林中继续选择抗性、速生、纤维含量高的优良单株,通过无性繁殖培育出适合东北地区种植的平原杨树纤维用材林新品种(系)。
In order to new species of breed fast-growing poplar fiber in plain plantation of good quality adapting to climate in Heilongjiang Province, hybridization combination was selected purposively to obtain 14 hybrids. Five hybrids of flail seeds, large seed yield, and gent hybrid seedling growth status were selected primarily. Superior individual of high resistance, fast growth, high fiber content were selected continuously in test plantation and new species of poplar fiber in plain plantation adapting to the northeast area was cultivated through vegetative propagation. In the test forest we would select good plant which was resistance strong, growth rapid and the content of fiber high from the five combinations. The new species of poplar in plain for fibre timber to adapt the northeastern regions were bred through asexual propagation.
