摘  要:
介绍了腐植酸多功能液态地膜的特性,通过大田试验研究了液态地膜对棉田土层下5cm、10cm的地温、0~60cm含水量和棉花成铃、产量的影响。结果表明,液体地膜具有一定的保温、保水功能,但效果不如塑料地膜显著;液态地膜的增产作用显著。此外,还分析了液态地膜的保温、保水机理及其应用前景。

摘  要:
In this paper, the characteristics of humic acid multi-functional mulch-film was introduced, and the applica-tion effects of mulch-film on ground temperature of 5 cm and 10 cm, soil water content of 0~60 cm layer, and the cot-ton growth were studied. The results indicated that the liquid film could preserve heat and retain soil water, but its effectwas inferior to the plastic mulching. The cotton yield was increased significantly when covered by liquid-film. In addi-tion, the mechanism of liquid-film to preserve heat and retain soil water, and its application prospect were also analyzed.
