大棚西瓜套姜栽培是安丘市近年来试验成功的一种新的高产高效栽培模式。1996年面积达到万亩以上。西瓜销往其他省市,姜远销东南亚国际市场,成为安丘市发展“双高一优”和创汇农业的骨干模式。一、模式特点和效益分析 (一)该模式改姜单作为西瓜、姜一年两种两收,复种指数增加一倍,提高了光能和土地利用率,缓解了西瓜、姜与其他粮菜争地的矛盾。 (二)充分发挥大棚保护地栽培的优势,通过套种技术,使姜比常规种植法早定植30天,晚收20天,延长姜生长期50天左右,使姜产量亩增1000～1500kg,增产40%左右。 (三)该模式可亩产西瓜6000kg,姜4000～4500kg。按近三年市场平均价格(姜8元/kg,西瓜2元/kg)计,亩产值可达45000元左右,比姜单作亩增效益 Greenhouse watermelon sets ginger cultivation is Anqiu City in recent years, a successful trial of a new high yield and efficient cultivation mode. In 1996 the area reached more than mu. Watermelon sold to other provinces and cities, ginger exported to Southeast Asian international markets, become Anqiu City Development “double high and one excellent ” and the backbone of foreign exchange earnings model. First, the model features and benefits analysis (a) the model to change as a single ginger watermelon, ginger two kinds of two incomes a year, double cropping index doubled, improve light and land utilization, ease watermelon, ginger and other food Dispute over the land. (B) give full play to the greenhouse cultivation advantages, through interplanting technology, so that ginger than the conventional planting early planting 30 days, 20 days late harvest, extend the ginger growth period of about 50 days, so that ginger yield acres by 1000 ~ 1500kg, yield About 40%. (C) This model can produce 6000kg per mu of watermelon, 4000 ~ 4500kg of ginger. According to the average market price (ginger 8 yuan / kg, watermelon 2 yuan / kg) in recent three years, the output value of mu can reach about 45,000 yuan,
