摘    要:为了研究可降解地膜的农用特性以及对不同种可降解地膜进行择优,试验通过对比研究的方法,对一般大田条件下普通地膜,不同可降解地膜以及露地栽培条件下土壤的温度、水分以及产量性状进行了对比研究。结果表明:在玉米生育前期,各地膜组均可以有效提高地下0~40 cm土壤水分含量,地下5~25 cm土壤温度,保温作用持续65天,其保水保温作用均表现为普通地膜与可降解地膜1差异不大,可降解地膜2次之,露地处理最差。普通地膜、可降解地膜1、可降解地膜2玉米增产率分别为19.5%,22.0%和13.1%,说明可降解地膜1和普通地膜对玉米产量影响显著且差异不大。由此可得,可降解地膜1代替普通地膜从事农业活动具有实际可操作性。

Abstract:To explore the practicality of degradable films and select one between different degradable films by superior, the comparisons on the soil temperature, moisture, characters and outputs by ordinary plastic film, different degradable films and open cultivation under common natural conditions has been discussed through the method of contrastive analysis. The results showed that: each mulching group could increase the soil moisture in the 0-40 cm profile, the soil temperature in 0-25 cm profile in the earlier growth duration of corn compared with open-air, this heat preservation could last for 65 days, based on the preservation effects of water and heat, these groups could rank from higher to lower as follows: ordinary plastic film and degradable film 1 > degradable film 2 > open cultivation. Their increase rates of degradable film 1, plastic film and degradable film 2 respectively were 19.5%, 22.0% and 13.1%, the degradable film1 had the similar influence. Thus, degradable film 1 replace plastic film is operational.
