摘　　要：研发和使用可降解液态地膜被认为是治理塑料地膜白色污染的一种有效应对措施。研究了在腐植酸可降解液态地膜中添加稀土微肥硝酸镧对地膜使用性能的影响。结果表明,添加稀土微肥不仅可以明显改善地膜的增温性能,使其达到或接近普通塑料地膜的水平,而且加入稀土微肥后还能更有效促进作物生长发育,达到增产增收的目的。在腐植酸液态地膜中添加稀土微肥是改进液态地膜性能的一种有效措施,有必要开展进一步的深入细致研究。It has been considered as an effective way to solving the white pollution of plastic mulching film that developing and using degradable liquid mulching film. In this paper, rare earth micronutrients lanthanum nitrate was selected and added into humic acid degradable liquid mulching film, and its influence on their application performance was studied. The results indicated that not only the warming effect can be improved to approaching the level of usual plastic film mulch, but also yield and income increase can be fulfilled by adding rare earth micronutrients. It should be worthy further studying on this new way to improve the properties of liquid mulching film.
