马铃薯应用液态地膜效果试验

摘要

Objective The aim was to study the application effect of Liquid film on virus-free potato. [Method] By contrast test , the effect of soil moisture, temperature, potato growth, seedling and yield were analyzed with liquid film or common film. [Result] Application of liquid film could improve soil moisture , temperature, no manual seedling accelerating potato growth process. But the problem of unreasonable concentration ratio and sprayer blocking were detected. [Conclusion]The concentration ratio needed to adjust for large area externsion.%[目的]对脱毒马铃薯采用液态地膜覆盖栽培，并对其应用效果进行研究。[方法]采用对比试验，分析液态地膜、普通地膜对土壤墒情、土壤温度、马铃薯生长进程、苗情及产量的影响。[结果]液态降解地膜具有提高土壤墒情、土壤温度、不用人工放苗、加速马铃薯生育进程、提高产量和质量的作用，但存在浓度配比不合理，堵塞喷雾器的现象。[结论]液态膜原料配比还需要进一步调整，为大面积推广奠定基础。
