流动沙地木麻黄“大苗深栽”造林效果分析

Analysis on Effects of Casuarina equisetifolia Afforestationby Deep-planting Strong Stocks on Shifting Sand

在海南省昌江县西海岸存在诸多不利于植树造林因素的流动沙地上,海南省林科所科技攻关人员采取了木麻黄“大苗深栽”的营林技术造林效果明显。至今已营造试验林亩,推广造林万亩,使风沙危害得以初步控制,生态环境日趋好转,是流28121.5动沙地治沙造林的一项行之有效的措施。

Experimental plantation of casuarina equisetifolia was set up by deep-planting strong stocks method on shifting sand which was unsuitable for planting at the west coast of Changjiang County,Hainan Province.It was found that the strong stocks above 1.5m in height and 1.0cm in diameter at foot were better in growth and stand quality.The survival percentage was increased when the planting depth was 40cm and over.Deep-planting strong stocks is an effective method for shelter-belts afforestation on coastal shifting sand.
