为了保证全省飞播造林的质量,对飞播造林进行科学化管理,今春,我们对有飞播造林任务地、县的飞播用种进行了质量检查。通过这次检查,我们认为飞播造林用种存在下列一些问题急需解决,主要有:一、种子纯度低。今春我省飞播造林共调马尾松种子48925公斤。除自采马尾松种2500公斤纯度较高外,从外地调进的马尾松种子46425公斤普遍不纯,不同程度地混有黑松、侧柏或云南松种子,有部分种子甚至以黑松为主。 In order to ensure the quality of aerial seeding afforestation in the whole province and scientific management of aerial seeding and afforestation, in spring, we carried out quality inspection on the aerial seeding use of the sites and counties for aerial seeding and afforestation. Through this inspection, we believe that the following problems need to be solved in aerial seeding afforestation, mainly including: First, the seed is of low purity. This spring, the province’s aerial seeding afforestation 48925 kilograms of Masson pine seeds. In addition to the high purity of 2 000 kg of Pinus massoniana, 46425 kg of Pinus massoniana seeds imported from the field were generally impure, mixed to varying degrees with black pine, oriental arborvitae or Pinus yunnanensis seeds, the Lord.
