【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5 cm、10 cm地温、0～60 cm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,本文还分析了液态地膜的保温保水机理及其应用前景。更多还原

【Abstract】 This article specifically introduced the humic acid multi-purpose liquid-film’s characteristic. Effects of mulching with liquid-film on the temperature of the 5 cm and 10 cm cotton field, and the soil water contains of 0~ 60cm cotton field by outdoor experiment. The result indicated: The liquid-film has a certain function to preserve heat and to guarantee the water, but the effect was inferior to the plastic mulching; In addition, this article also analyzed the mechanism to preserve heat and guarantee the soil water of the liquid-film mulching and its application prospect.更多还原
