降解地膜在烟叶生产上的应用示范研究
摘要 开展降解地膜与普通地膜在烟叶生产上的对比试验研究，测定比较使用不同地膜的烟叶生育期、经济效益、使用成本和地膜降解情况。结果表明，使用降解地膜与普通地膜的烟叶生育期基本一致，使用降解地膜烟叶产量降低30 kg/hm2，产值降低1 044元/hm2，上等烟比例降低3个百分点，但差异不显著。使用降解地膜成本增加89元/hm2，且在田间可逐步降解，但与烟叶生育期不完全同步，需进一步改善其降解性能。

Abstract The comparison test of the degradable film and ordinary film in the production of tobacco leaves was carried out，and the growth period，economic benefit，cost of use and the degradation of film were measured and compared. The results showed that the growth period of tobacco leaves was basically the same when the degradable film or the ordinary film was used. The yield of tobacco leaves decreased by 30 kg/hm2，the output value decreased by 1 044 yuan/hm2，and the proportion of the top tobacco decreased by 3 percentage points，but the difference was not significant. The cost of using degradable film increased by 89 yuan/hm2，and could be degraded gradually in the field，but it was not completely synchronized with the growth period of tobacco leaves，and its degradation performance should be further improved.
