对杂交相思采穗圃营建、整形修剪、扦插育苗等技术进行了初步研究。采穗圃宜选址在土壤肥沃、光照充足的地方;定植后株行距控制在40cm×50cm;缓苗后在母株15~20cm时进行截顶定干,能有效提高穗条质量与产量。采用黄心土作基质进行嫩枝扦插,应用生根剂植物生长调节剂IBA、ABT处理插穗,能显著提高扦插苗的生根率,其中IBA0.05%效果较好。扦插苗木生长到20~30cm且健壮无病虫害即可出圃造林。 On Acacia scion nursery construction, plastic pruning, cutting seedling and other technologies were initially studied. The earpick should be sited in a fertile, well-lit place; the spacing of the plants after planting should be controlled at 40cm × 50cm; and the cuttings should be cut and fixed at the height of 15 ~ 20cm when the moths are seedling, which can effectively improve the quality and yield of the sliver. Using yellow heart soil as the substrate for softwood cutting, application of rooting agent plant growth regulators IBA, ABT processing cuttings, can significantly increase the rooting rate of cutting seedlings, of which IBA0.05% better. Cutting seedlings grow to 20 ~ 30cm and no pests and diseases can be nursery Afforestation.
