黑瓜籽是兰州的名特产品,不仅有着悠久的栽培历史,而且具有板大、皮薄、口松、肉厚等特点,以“兰州大板”享誉中外,质量居全国之冠,深受海内外消费者的欢迎。但是,兰州市黑瓜籽的集中产地皋兰县大部分乡村至今仍沿袭着传统的种植方式,产量低而不稳,受自然条件的约束很大,严重影响黑瓜籽生产的发展。为此,我们从1982年开始推广“一水地覆膜黑瓜籽栽培”技术。1983年,省、市、县三级农技站配合协作,在全县进行了大面积多点示范,覆膜800多亩,经测产,平均亩产107.9公斤,1989年,地膜覆盖示范田每百斤 The specialty of Lanzhou is not only the long history of cultivation, but also the characteristics of big board, thin skin, loose mouth and thick flesh. The quality of Lanzhou Dafan is the highest in China and the highest in the country. Welcomed by consumers at home and abroad. However, most of the villages in Gaolan County, the concentrated source of black melon seeds in Lanzhou City, still follow the traditional methods of cultivation. Their yields are low and unstable, which are greatly constrained by natural conditions and seriously affect the development of black melon seeds. To this end, we started in 1982 to promote “a water-covered cultivation of black melon seeds” technology. In 1983, provincial, municipal and county agricultural stations with the collaboration of three large-scale multi-point demonstration in the county, covering 800 acres, the measured output, the average yield of 107.9 kilograms in 1989, mulching film demonstration field Per hundred pounds
