造林能否成功,主要取决于造林技术措施是否得当、合理,栽培树种是否因时因地顺乎自然的节律。我省山区国营林场新造人工林200余万亩,已陆续成林成材,立木蓄积达320万立方米,平均每亩蓄积1.6立方米,综合成本47元,其中直接成本20—30元,而立木蓄积的总产值达3亿零400万元,为基建投资1亿元的三倍多。对促进我省工农业生产,自然生态平衡调节气候、涵养水源,提供用材起到积极骨干作用。现就有关山区造林技术措施效果的观测分析和意见,综述如下:
The success of afforestation depends mainly on whether afforestation technical measures are properly and reasonably cultivated for natural reasons. More than 200 million mu of newly-built plantations in the mountainous state-owned forest farms have gradually become forest timber, and the volume of standing trees has reached 3.2 million cubic meters with an average volume of 1.6 cubic meters per acre. The comprehensive cost is 47 yuan, of which the direct cost is 20-30 yuan, The accumulated output value reached 300 million and 400 million yuan, more than tripled for infrastructure investment of 100 million yuan. To promote industrial and agricultural production in our province, the natural ecological balance climate regulation, conservation of water sources, providing timber plays an active backbone. The observations and analysis on the effects of afforestation technical measures in mountain areas are summarized as follows:
