甜瓜双膜覆盖栽培技术就是利用地膜覆盖再加小拱棚的双层保护措施,进行合理栽培甜瓜的一项新技术,它的重大意义在于,使甜瓜上市时间提前了一个月甚至一个半月,从而在黑龙江北方高寒地区,人们在6月中旬便能吃上当地的甜瓜。该项目在绥化市进行了7年的试验示范,获得了成功。该项目的优点:一是产品上市时间早,一般在6月20日产品成熟上市,早的可在6月15日上市;二是品质好,由于5、6月份光照充足,昼夜温差大,干物质积累量增多,所以瓜味特别香甜;三是节水免耕,在深松的基础上,实行双膜覆盖,可以保持良好的土壤湿度,而且可免耕作和除草;四是经济效益突出,应用该项技术,产品提 Melon double-film cultivation technology is the use of double-layer plastic film cover plus a small protective measures for reasonable cultivation of melon a new technology, its great significance is that the melon market an hour earlier or even a month and a half, so that Heilongjiang northern alpine region, people will be able to eat the local melon in mid-June. The project was successfully piloted in Suihua for seven years. The project’s advantages: First, the product market early, generally mature products listed on June 20, early listed on June 15; the second is good quality, due to sufficient light in May and June, the temperature difference between day and night, dry The accumulation of material increased, so the melon taste particularly sweet; Third, water-saving no-tillage, on the basis of subsoiling, the implementation of double film coverage, can maintain good soil moisture, but also free of tillage and weeding; Fourth, highlighting the economic benefits, Application of the technology, product mention
