林木种子是林业生产的物质基础,种子数量的多少,直接影响到林业生产和经营者的利益。如果林木种子严重短缺,将会给造林育苗带来难以弥补的经济损失。1987年,由于我省受气候因素影响马尾松、杉木种子结实量普遍减少,为种子小年,加之采种工作抓得不紧,实际产量远远低于计划产量,加剧了种子供需矛盾,影响了1988年育苗造林任务的完成。如林木种子生产收购过多,积压过大,必将给经营者带来经济上的损失。因为林木种子既是林业生产的产品,又是林业生产的资料,产于林业,用于林业。除了部分经济林木种子可作 Forest seed is the material basis of forestry production, the number of seeds, a direct impact on the interests of forestry producers and managers. If the serious shortage of forest seed, will bring afforestation nursery irreparable economic losses. In 1987, due to the influence of climatic factors on the masson pine in China, the seed-setting capacity of Chinese fir was generally reduced. It was a small year for seeds, and the work of seed collection was not tight. The actual output was far below the planned output, aggravating the contradiction between supply and demand of seeds and affecting 1988 seedling afforestation mission completed. Such as forest seed production acquisition too much, overstock, will bring economic losses to the operator. Because forest seed is both a product of forestry production and a material of forestry production, it is produced in forestry and used in forestry. In addition to some economic forest seeds can be made
