以麦套春棉为材料，研究了缩节安（ＤＰＣ）和ＫＨ２ＰＯ４ 单独和混合浸种对棉苗叶片持水力及茎叶输导组织的解剖结构的影响，结果表明：ＤＰＣ， ＫＨ２ＰＯ４ 和ＤＰＣ＋ ＫＨ２ＰＯ４ 处理对棉苗叶片持水力及茎叶输导组织的结构都有不同程度的影响，其中以ＤＰＣ＋ ＫＨ２ＰＯ４ 处理效果优于单独使用。该处理能提高叶片的持水力，改善输导组织的结构，表现为维管束数目多，木质部、韧皮部面积大且发育好，木质部导管数目多。因而叶的输导功能得以加强，这对于提高棉苗的水分利用效率和抗旱性以及培育壮苗有积极的作用。
The effects of DPC, KH2PO4 and DPC + KH2PO4 treatments on the water holding capacity and the anatomical structure of stem-leaf tissue in paddy seedlings were studied by using wheat straw spring cotton as raw material. The water-holding capacity of cotton seedling leaves and the structure of stem-leaf transplanted tissue all had different degrees of influence. Among them, the treatment with DPC + KH2PO4 was better than single use. The treatment can improve the water holding capacity of the leaves and improve the structure of the guiding tissue, which is characterized by a large number of vascular bundles, large and well-developed xylem and phloem regions, and a large number of xylem catheters. Thus, the translocation of the leaf is enhanced, which has a positive effect on the improvement of water use efficiency and drought resistance of cotton seedlings and the cultivation of strong seedlings.
