油松分布范围广、适应能力强,是我省重要的造体树种之一。从40年代起至今,辽宁南部地区的油松,遭受日本讼干蚧的严重为害,现已蔓延至辽东和辽北地区。多年来使用化学药剂防治,虽然对害虫有所控制,但花费大量资金,日严重污染环境,危害人畜安全,使油松发展受到限制。我们自1980年以来,进行了抗松干蚧育种的研究。从理论上和实践上,已探索出油松对日本松干蚧(以下简称松干蚧)的抗性规律和
Pine oil distribution of a wide range of adaptability, is one of the important species of our province. Since the 1940s, Pinus tabulaeformis in the southern part of Liaoning has been severely damaged by Japanese lawns and scales and has now spread to the areas of eastern Liaoning and northern Liaoning. Over the years the use of chemical control, although the control of pests, but spend a lot of money, the day serious pollution of the environment, endangering the safety of people and livestock, so that the development of pine is restricted. Since 1980, we have carried out research on the breeding of loquat. In theory and in practice, we have explored the resistance of Pinus tabulaeformis to the Japanese pine scale (hereinafter referred to as the pine scale)
