不同类型地膜在茄子栽培中的应用研究初报

为在蔬菜生产中推广和应用适宜的地膜，实现绿色高效、清洁环保栽培，采用全生物降解地膜、高强度耐候地膜、普通黑地膜等不同地膜在茄子栽培中进行覆盖应用，考察不同地膜对茄子生育性状和产量的影响，比较不同地膜裂解程度、保温保湿及防草性能。结果表明：在茄子生育期内，高强度耐候地膜不易碎裂，仅出现2～20 cm的裂缝或孔洞，具有良好的保温保湿及防草效果，而全生物降解地膜在茄子生长后期出现20 cm以上的裂缝或孔洞（直径），在茄子前、中生育期具有保温保湿效果，但不能在茄子生育期内完全分解，有待进一步加强材料性能的改善。

Preliminary Study on The Application of Different Types of Mulch Film in Eggplant Cultivation

Abstract: In order to popularize and apply suitable mulch film in vegetable production and realize green, efficient, clean and environmental protection cultivation, different mulch films such as full biodegradable mulch film, high-strength weather-resistant mulch film and ordinary black mulch film were used in eggplant cultivation, the influences of different mulch films on eggplant growth traits and yield were investigated, and the properties of different mulch film cracking degree, heat preservation, moisture preservation and grass prevention were compared. The results showed that the high-strength weather-resistant mulch film was not easy to crack during the growth period of eggplant, and only appeared cracks or holes of 2-20 cm, which had good effects of heat and moisture preservation and grass prevention. While the full biodegradable mulch film appeared cracks or holes (diameter) of more than 20 cm in the late growth stage of eggplant, and had heat and moisture preservation effects in the early and middle growth stage of eggplant, but could not be completely decomposed in the growth stage of eggplant, and further improvement of material performance was needed.
