我县针叶树移植育苗,在解放前都是床作。解放后,造林事业飞速发展,苗圃职工为了尽快发展育苗生产,满足造林需要,在建国初期就改革了针叶树移植作业方式,由床作改为垅作。开始实行是大垅错锹移植,后来又进而改为大垅双行移植。床移植,每株幼苗占有的土地营养面积和空间都比较均匀,单产较高,苗木质量也较好。但解放初期,由于苗圃机械化水平非常低,床移植、作床、中耕松土、起苗等作业全靠手工操作。实行垅作后,作垅、中耕松土、起苗等作业都可用畜力进行。因而,当时大大推动了育苗事业的发展,并很快推广全省。 Coniferous transplant nursery in our county, are bed before liberation. After the liberation, the rapid development of afforestation, nursery workers in order to develop nursery production as soon as possible to meet the needs of afforestation, in the early years of the PRC to reform the coniferous transplant mode of operation, from bed to do. The beginning of implementation is a large spade spade shovel transplant, and later changed to double-breasted double line transplant. Bed transplant, each seedling possession of land area and space for nutrients are relatively uniform, high yield, seedling quality is better. However, in the early stage of liberation, due to the very low level of mechanization of nurseries, bed transplanting, bed planting, cultivating loose loam, raising seedlings and other operations all depend on manual operation. After the implementation of the masterwork, for 垅, cultivating loose soil, seedlings and other operations are available animal husbandry. Thus, then greatly promoted the development of nursery career, and soon promote the province.
