复县万家岭乡,地处大连市北部高寒山区,常年降雨量平均600多毫米,无霜期160天左右。由于土壤瘠薄,春旱严重,水稻亩产仅150～200公斤左右,为此,万家岭乡技术站,1982年在刘沟搞了1亩水稻旱种地膜覆盖栽培品种对比试验,亩产370.1公斤,比未覆膜的水稻增产125％。1984年推广230亩,平均亩产415公斤,其中谢英金的3亩旱种覆
Wanjialing Township, Fuxian County, located in the northern alpine mountainous area in Dalian, perennial rainfall average more than 600 millimeters, frost-free period of 160 days. Due to the infertile soil and severe spring drought, only about 150-200 kg of rice per mu is produced. For this reason, Wanjialing Township Technical Station has conducted a comparative experiment on dry cultivation of mulched film mulching cultivars in Liugou in 1982, with a yield of 370.1 mu Kg, 125% more yield than uncoated rice. In 1984 to promote 230 acres, the average yield 415 kilograms, of which Xie Yingjin 3 acres of dry cover
