房县位于鄂西北山区,海拔高度180～2486米。玉米种植的最高海拔高度为1600米,常年种植面积为35万亩。它占粮食作物面积的70％;占旱地粮食作物面积的88％,为山区的主要粮食作物,也是山区人民食物的主粮。白1983年开始推广玉米地膜覆盖栽培,其选用的配套品种为郧单1号。通过试验和大面积生产的对比调查,玉米地膜覆盖栽培的平均亩产为375公斤,比露地栽培的能够提早15～20天播种和提早20天左右成熟,平均亩产提高130公斤,增产530.1％,比薄膜育苗移栽的能够提早5—7天成熟,平均亩产提高韶公斤,增产26.3％,是山区人民解决温饱、脱贫致富的主要先进技术。但是,有些人则认为低山地区的温度高,无霜期短,
Fang County is located in the mountainous area of northwest Hubei Province, with an elevation of 180 ~ 2486 meters. The highest altitude of corn planting is 1,600 meters, perennial planted area of 350,000 mu. It accounts for 70% of the area of food crops; it accounts for 88% of the area of dry land for food crops, is the main food crops in the mountains, but also staple food for mountain people’s food. White 1983 began to promote the cultivation of plastic film mulching, the selection of supporting varieties Yun single No. 1. Through the test and comparative survey of large-scale production, the average mu yield of maize mulching is 375 kg, which can be planted 15 to 20 days earlier than open field and matured about 20 days earlier. The average yield per mu is 130 kg and the yield is increased by 530.1% , Than the film nursery transplanting can be mature 5-7 days earlier, the average per mu increase Shaogu kg, an increase of 26.3%, is the mountain people to solve the food and clothing, poverty alleviation and prosperity of the main advanced technology. However, some people think that low-temperature areas have high temperatures, frost-free periods are short,
