| 摘 要： | 针对福建沿海地区木麻黄迹地更新难的问题,在平潭县芦洋农场进行了农地与迹地营造木麻黄防护林带更新试验,根据两带木麻黄生长情况,从土壤机械组成、化学基本组成以及土壤微量营养元素与木麻黄小枝微量营养元素铜、锌、硼、钼的含量进行分析比较,结果表明:长期种植木麻黄迹地的酸性沙质土,土壤中有效钼长期消耗,造成土壤有效钼的缺乏,是迹地木麻黄生长不良的重要因素。

| Abstract: | To counter the difficult problem of cutting woodland of Casuarina equisetifolia on coastal area of Fujian,regeneration experiments of constructing protection shelterbelt of Casuarina equisetifolia on farmland and slash on Luyang farm of Pingtan County were conducted.According to growth situation of Casuarina equisetifolia with 2 shelterbelts,analyzing the mechanical composition of the soil,basic composition of chemistry,content of nutritious trace element of the soil and content of nutritious trace element of sprig of Casuarina equisetifolia——Cu,Zn,B,Mo,results showed that the sand soil in which available Mo has been used up over a long period of time because of planting Casuarina equisetifolia for a long time.Being deficient in available Mo of the soil was important effecting factor on the growth of Casuarina equisetifolia. |
