西引2号大麦是西北农学院作物栽培教研组1980年由日本长野县引进的,原名为“浅间麦”。1984年经陕西省农作物品种审定委员会审定通过。1986年在我区孝感市,云梦县共试种21亩,表现很好,平均亩产264.4公斤,比早熟3号大麦亩增112.85公斤,增产74.46%。其中孝感市农科所种植0.739亩,实收大麦230.5公斤,折亩产316.41公斤,比相同条件下的蒙克尔大麦增产43.17%。品比试验结果,西引2号亩产269.45公斤,比鄂恩1号小麦增产9.98%,比早熟3号大麦增产47.24%。1986年夏收后,全区从陕西调进65万公斤种子,播种5.49万亩。西引2号在我区发展之快,属前所未有。
West lead No. 2 barley is a crop cultivation research group of Northwest Agricultural College introduced in 1980 by Japan’s Nagano Prefecture, formerly known as “shallow wheat.” In 1984 by the Shaanxi Provincial Crop Variety Approval Committee approved. 1986 in Xiaogan City, Xiaogan City, Yunmeng County, a total of 21 acres planted, performed well, an average of 264.4 kilograms per mu, more than early maturing No. 3 barley 112.85 kilograms, an increase of 74.46%. Among them, 0.739 mu was planted by Agricultural Science Institute of Xiaogan City, 230.5 kilograms of barley were harvested and 316.41 kilograms of mu per mu were produced, an increase of 43.17% over that of Mongolian barley under the same conditions. Compared with the test results, the yield per mu of 269.45 kg in West Ind. 2 was 9.98% higher than that of E’en 1 and 47.24% more than that of the early-maturing barley. After the summer harvest in 1986, the whole region transferred 650,000 kilograms of seeds from Shaanxi and sown 54,900 mu. West cited No. 2 in our region developed rapidly, is unprecedented.
