对腐植酸多功能可降解黑色液态地膜进行了试验室盆栽试验和大田试验,通过应用表明,土壤表面喷洒系列液态地膜,可在地表面形成一层黑褐色土膜,提高土壤湿度,减少土壤水分蒸发,降低0～50cm土体中的盐分含量,增加土壤肥力,促进植物生长。通过对照表明,系列液态地膜对农作物的效果与不施加地膜相比具有明显的抗旱、增温作用和早熟增产效果,与塑料地膜相比效果相当,但液态地膜喷施后40～60天逐渐降解,2～3个月降解为腐植酸类(有机肥),没有白色污染;翻压入土后,可以改良土壤团粒和改善土壤通透性。
The humic acid multifunctional biodegradable black liquid film was tested in laboratory pot experiments and field trials. The application shows that spraying a series of liquid film on the soil surface can form a dark brown soil film on the surface to improve soil moisture and reduce soil moisture Evaporation, reduce the soil salt content 0 ~ 50cm, increase soil fertility and promote plant growth. The comparison shows that the effect of series of liquid plastic film on crops has obvious drought-resistance, temperature-increasing effect and early-maturity increase effect compared with non-application of plastic film, which is equivalent to plastic film, but gradually degrade , 2 to 3 months degradation of humic acid (organic fertilizer), no white pollution; turn into soil pressure, soil aggregates can improve and improve soil permeability.
