冬小麦一生只浇一水,就能获得亩产414.7公斤的产量,你可能不大相信,但这是事实。6月上旬,河北省科委受国家科委委托,邀请农业部和省内外专家,对北京农业大学吴桥县龙王河试验区承担的节水型吨粮田—冬小麦节水高产高效栽培技术研究项目进行了验收。专家们听取了研究报告,全面察看了吴桥县范屯乡春季只浇一水的200亩试验和生产示范田,通过157样点实测,平均亩穗数55.1万穗,穗粒数22.6粒,千粒重按常年37克计算,理论产量按90%折,亩产达414.7公斤,大大超过了原定亩产250公斤的指标。在我国北方麦区,冬小麦一生一般得浇三次水,试验区的小麦为什么只浇一水就能获得如此高的产
It is a fact that you may not be able to believe that winter wheat will only yield 414.7 kilograms of mu per month when it is poured into water only once. In early June, Hebei Science and Technology Commission commissioned by the State Science and Technology Commission, invited the Ministry of Agriculture and experts from inside and outside the province, to Beijing Agricultural University Wuqiao County Longwang River pilot area to undertake water-saving ton grain fields - winter wheat water-saving and high yield and efficient cultivation technology research project Acceptance was carried out. The experts listened to the research report and comprehensively examined the 200-mu trial and production demonstration field of Fan Tun Township, Wuqiao County, which was flooded with water in spring. The average number of acres per ear was 551,000 ears, the number of grains per ear was 22.6 and the weight of thousand-grain According to perennial 37 grams, the theoretical yield by 90% off, per mu up to 414.7 kilograms, greatly exceeded the original target of 250 kilograms per mu. In northern China wheat area, winter wheat generally have to be poured three times the life of water, the test area of wheat why only a water can get such a high yield
