林木种子收集是林业生产中一个很重要的环节,优良的种子是改善林分质量和提高木材产量的重要条件。美国米苏拉设备研究中心为了评定现有的种子和球果收集设备,了解对新设备的建议,于1977年进行了一次世界范围的调查。各国种子工作者所列举的球果和种子收集设备至今仍在继续使用。
Forest seed collection is a very important link in forestry production. Good seed is an important condition to improve stand quality and increase timber output. The Missoula Equipment Research Center conducted a worldwide survey in 1977 in order to assess existing seed and collection equipment for cones and to learn about new equipment. Cones and seed collection equipment listed by national seed workers are still in use today.
