【摘要】 从2006年到2009年,中国国家林业局与意大利环境国土海洋部合作,应用意大利机械化集雨抗旱整地造林技术——"瓦勒拉尼系统"在内蒙古赤峰市进行造林试验示范。与传统的人工整地造林相比,降水利用率提高两倍,土壤紧实度降低82%,土壤含水率平均提高60%,造林成活率提高30%左右。对"瓦勒拉尼系统"整地造林各项技术参数的测试分析表明,该系统具有深耕集雨、快速高效、经济实用、适应性强等特点。该系统在集雨抗旱造林方面具有的优越性和先进性,为该系统在中国干旱区推广应用提供了科学依据和实用技术方法。更多还原

【Abstract】 The "Vallerani System" invented by Italian experts,a technology of mechanical land preparation,rainfall collecting and afforesting in arid area,was used in experiment and demonstration of afforestation in Chifeng,Inner Mongolia,China.Compared with the traditional manual land preparation and domestic mechanical land preparation for afforestation,the superiority of the "Wallerani System" in land preparation and afforestation was obvious: the rainfall collection efficiency increased 2 times,the soil moisture increased 60%,the soil compact degree reduced 82%,and the survival rate of planted trees increased 30%.Therefore,the "Vallerani System" was successful in land preparation and afforestation in Inner Mongolia,and it was a valuable afforestation technology in China.更多还原
