辽宁省各地柞蚕场主要靠种子育苗发展柞树,但养蚕价值较高的辽东栎、麻栎等,供采种的母树较少。1977年以来,我们用扦插方法育苗,扦插生根率达到60％以上。辽东栎、麻栎、蒙古栎和栓皮栎的不同树龄新枝和硬枝扦插,都能生根。幼龄母树比老龄树硬枝生根率高,半木质化绿枝比硬枝生根率高。插床铺10厘米厚的(石至)石或细沙作基质,下边铺些马粪提高插床温度,插床上加盖高60厘 Tussah field around Liaoning Province, mainly by seedling nursery development of oak trees, but higher value of sericulture Quercus liaotungensis, Quercus, etc., for the mother planted less trees. Since 1977, we use cutting method nursery, cutting rooting rate reached 60%. Quercus liaotungensis, Quercus acutissima, Quercus mongolica and Quercus variabilis can all take root. Juvenile parent trees have higher rooting rates than hardwood branches of old age trees and semi-lignified green branches have higher rooting rates than hardwood branches. Bedded bed 10 cm thick (stone to) stone or fine sand as a matrix, laying Ma horse below to raise the temperature of the bed, capping the bed with a high 60%
