乌桕林地综合经营技术研究

Study on Comprehensive Management Technique of Chinese Tallowtree Land

本课题围绕如何有效地提高乌桕营林的经济效益,从不同套种组合、不同造林方式、不同造林密度等方面开展对乌桕林地综合经营技术的研究。研究结果表明,乌桕林密度以4×5m或5×6m较为合适;合理套种,实行桕、农混作,是当前大幅度提高乌桕林地经济效益的简捷而有效的措施;采用直播定砧、良种嫁接造林、套种绿肥、对土壤浅薄的现有桕林实施爆破法补充整地等均有显著促进乌桕结实,提高桕林经济效益的作用。本课题研究成果的推广应用,还使良种采穗圃穗条产量提高92.5%。

Study on comprehensive management technique with the objective of increas-ing economic effect by different interplantion forms, different afforestation methods and diff-erent afforestation density showed that Chinese Tallowtree (Sapium Sebiferum) forest densitywith 4×5m or 5×6m was optimal, a simple and effective way to increade economic effect ofChinese Tallowtree forest land was rational interplanting, and mixted farming with agricultu-ral crops; direct seeding used as stock, afforestation after grafting with improved variety,interplanting green manure, ground making with blast method etc. had evident effect on seedsetting and economic benefit of Chinese Tallowtree forest. Extention of this result couldincrease cutting output of 92.5% in improved variety cutting orchard.
