| 摘 要： | 雷州半岛浅海沉积物发育的桉林地砖红壤贮水量较低 ,0— 10 0 cm土层只有 15 0 m m;主要受降雨分布的影响 ,呈明显的季节性变化 ,季节性干旱时间较长 ;即使在雨季 ,由于气温较高 ,土壤水分在短期内也可出现较大幅度的变化 ,容易产生干旱。如何减少干旱威胁是桉树生产必须解决的重要课题。

| Abstract: | The moisture status and its meaning of latosol under Eucalyptus in Leizhou peninsula was characterized by lower in stored water content, only being 150 mm in 0-100 cm soil layer; Controlled by rainfall distribution, the stored water presented clear annual and seasonable changes, being longer in dry season; Even in rain season, very wide range in change of the stored water content within a short time could bring out, which means that the latosol under Eucalyptus is quite easy to suffer from drought. More attention should be paid to relieving the effect of water stress on Eucalyptus growth. |
