摘要
通过田间试验,研究了氧化—生物双降解地膜的上机性能、降解性能、增温保墒效果,及其对烤烟生长发育、经济性状和土壤理化性状的影响。结果表明:氧化—生物双降解地膜的上机性能与普通地膜没有差异,能够满足机械化覆膜的要求;其降解性能较好,不同配方的地膜降解速率不同;在降解破裂前的增温保墒效果与普通地膜相同,对烟株的生长发育和烟叶的经济效益无影响,并对增加土壤有机质含量具有积极作用。总体来讲,氧化—生物双降解地膜具备普通地膜的功能,能够满足烤烟生长发育需求,可有效解决"白色污染"问题。
Through field experiment, the author studied the mechanical property, degradable features and temperature-increasing and soil-moisture-conserving effects of oxydic-biodegradable mulching film, and analyzed its effects on the growth, development and economic characters of flue-cured tobacco, as well as on the physicochemical properties of soil in western Henan. The results showed that oxydic-biodegradable mulching film had the same mechanical property as ordinary plastic film, and it could completely meet the requirements of mechanized film-mulching. The degradation rate of oxydic-biodegradable mulching films with different formulations was different, but their degradation property was relatively good. Before degradation and fracture, oxydic-biodegradable mulching film possessed the same temperature-increasing and soil-moisture-conserving effects as ordinary plastic film, it had no influences on the growth, development and economic characters of tobacco plants, and it also could increase the soil organic matter content. In general, oxydic-biodegradable mulching film had the same functions as ordinary plastic film, it could meet the demands of flue-cured tobacco growth and development, and could effectively solve the 'white pollution' problem. Thus, oxydic-biodegradable mulching film has good popularization prospects.
