云杉幼苗培育栽植技术研究

Study on the Cultivation and Planting Techniques of Spruce Seedlings

为更好地推广云杉种植,结合河西地区实际,通过研究云杉移栽苗在覆膜与露地种植模式下,分析研究需水量、栽植成本、越冬能力、除草方式等方面,总结了适合河西地区云杉幼苗移栽的实用技术。结果表明:选择覆膜移植方法移栽云杉小苗年可节水90m3,选择化学除草可降低管护成本5 550元·hm^(-2),故河西地区选择覆膜栽植云杉,以化学除草方式为主,人工除草为辅,可大幅度降低苗木移植管护费用,进一步为大规模发展云杉提供技术支撑。

In order to better popularize spruce planting and combine with the reality of Hexi area,the suitable technology for the transplanting of spruce seedlings in Hexi area was summarized by analyzing the water requirement,planting cost,the ability of overwintering and the way of weeding under the film mulching and the field planting pattern of the spruce transplanting seedlings.The results showed that the selection of transplanting method could save 90 m3 for the year of transplanting spruce small seedlings,and the selection of chemical weeding could reduce the cost of management and maintenance by 5 550 yuan per hectare.Therefore,the planting of spruce by plastic mulching in Hexi area,mainly by chemical weeding and artificial weeding can greatly reduce the cost of seedling transplantation and nursing.Spruce is provided with technical support.
