摘要
通过对5个海岛棉品种土壤水分动态变化分析研究,结果表明,不同海岛棉品种各生育期土壤含水量、土壤蓄水量以及水分利用效率存在差异。含水量最高的土层是80-100cm,最低的是0~20cm。这种规律性变化与棉花根系的发育特点、吸收特点有关。新海21是节水型品种,能够较充分的利用有限的灌溉水,在干旱半干等地区具有强大的优势。
The dynamic change of soil water of 5 island cottons was studied, The results show that there are distinct difference in soil water content and water use efficiency among different varieties. The layer of the most high soil water content is 80- 100 cm,while the most lower layer is 0-20 era. The rule change related with root. New sea 21 are varieties which can save water effeciently,so they have advantage in arid and semi-arid region.
