河南省方城县烟叶生产一般3月中下旬移栽,8月中旬收获结束,其间耕地闲置两个月以上,夏播绿豆在该县适播期为6月上旬~7月中旬,生育期65天左右,适合烟叶绿豆间作。在国家食用豆产业技术体系南阳综合试验站的指导下,从2011年起在全县广阳镇、清河乡进行了烟叶、绿豆间作生产技术探索,面积共计18 410m2,平均亩产绿豆58.5kg,其中2012年试验种植6 758m2,平均亩产绿豆51.75kg,2013年试验种植11 652m2,平均亩产绿豆62.4kg,在不影响烟叶生产的情况下,多收一茬绿豆,亩增加产值500元以上。
Henan Province, Fangcheng County, tobacco production in mid-late March transplanted in mid-August harvest ended, during which arable land idle for more than two months, summer sowing mung bean sowing period in the county from early June to mid-July, the growth period of 65 Days or so, suitable for mung bean intercropping. Under the guidance of Nanyang Integrated Experimental Station for National Edible Bean Industry Technology System, the production technology of tobacco leaf and mung bean intercropping has been explored in Guangyang Town and Qinghe Township of the county from 2011 onwards, covering an area of 18 410m2 with an average yield of mung bean 58.5kg, Among them, 6,758m2 were planted in 2012, with an average yield of 51.75kg per mu of mung bean. In 2013, 11,652m2 of mung bean was planted with an average yield of 62.4kg mung bean per mu. Without affecting the production of tobacco leaves, mulberry beans were harvested more than 500 yuan per mu .
