补充资料：地膜覆盖(plastic membrane mulching)
地膜覆盖(plastic membrane mulching)
用塑料薄膜覆盖地面的一种栽培措施。一般采用厚度为0.015mm左右的高压聚乙烯透明塑料微薄膜，有透光性好、导热性差、不透气，在低温易冻、热量不足条件下，可起增温、保墒、改善近地面气层的光热条件，促进土壤微生物活动，改善土壤理化性质，提高CO2浓度等作用。东北、华北和西北等地区，在棉花、花生、烟草、水稻、小麦、玉米、甘薯、马铃薯等方面获得明显的增产效果。
塑料微薄膜的种类有透明膜、黑色膜、灰色膜、黑白双重膜、铝箔膜等；有在薄膜内面涂有除草剂或杀虫剂的杀草膜或防虫膜；有按栽植作物株行距要求开好孔的有孔膜，还有厚度仅为0.008mm的低压聚乙烯微薄膜，每公顷用量仅为一般高压膜的40%左右。
覆盖方式有行间覆盖与根区覆盖，根区覆盖又可分为畦作覆盖、垄作覆盖、平作覆盖和沟作覆盖。
地膜覆盖度的计算方法，是以塑料薄膜的宽度和行距之比表示。生产上应用的覆盖度大多为50-80%。可分为两种形式：先播种后覆膜和先覆膜后打孔播种。覆盖时间，干旱少雨地区，早春整地或选墒后立即覆膜，防止土壤水分蒸发，待适温时播种，以保全苗。但春风较大的地区，不宜过早覆膜，以防大风揭膜。雨量较多或土壤水分充足的地区，可在播种前后覆膜。
覆盖时要将薄膜展开拉紧，使之紧贴地面，不得产生皱褶松弛或损坏膜面。薄膜的两侧、两头都要开沟埋入土中，边覆边埋，压紧压严。
