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。
The characteristics of humic acid multifunctional liquid plastic film were introduced. The effects of liquid plastic film on the ground temperature of 5 cm and 10 cm, water content of 0-60 cm and boll yield of cotton were studied by field experiments. The results show that the liquid film has a certain thermal insulation, water retention, but the effect is not as significant as the plastic film; liquid film significantly increase production. In addition, the liquid membrane insulation, water retention mechanism and application prospects are also analyzed.
