概述窿缘桉(Euca lyptus exserta)是一种乔木树种。原产澳洲北部。1958年以来,在海南儋州和太平林场等地大面积引种,由于造林时以水土保持、护路和防风为主,多采用高密度(株行距4×4或3×3.5市尺)造林。林木生长快,郁闭早,故出现早衰、早分化现象,必须及时进行间伐,给林木生长创造良好的条件,促进其速生丰产。为此,于1965年在儋州林场对1960年栽植的两段林带设置了9块标准地,采用强、中、弱三种强度的对比试验,现
Overview Euca lyptus exserta is a tree species. Origin of northern Australia. Since 1958, a large area has been introduced in Pizhou and Taiping Forest in Hainan. Because of water and soil conservation, road maintenance and windbreaking, afforestation with high density (4 × 4 or 3 × 3.5 rows) was mostly used in afforestation. Forests grow fast, canopy closed early, so there premature aging, early differentiation, we must promptly thinning, to create good conditions for the growth of trees to promote its fast-growing and high yield. To this end, in 1965 in Zhuozhou Forest Farm planted two blocks of forest in 1960 set nine standard ground, the use of strong, moderate and weak comparison of the strength of the three tests are
