从甘肃省农牧厅获悉,玉门市春小麦高产创建万亩示范片平均单产达到9 979.5kg/hm2,该产量是目前全国春小麦高产创建万亩示范片的最高纪录。集成创新和精准管理是玉门市春小麦高产创建中的主要措施,一是确定主导品种,项目区以酒春3号为主导品种,示范推广92157、陇春24号等新品种;二是确定播期播量,当土壤解冻10cm左右顶凌播种,播量为375~487.5 kg/hm2;三是科学运筹肥料,秋季犁地施有机肥,深翻后充分腐熟,结合灌水追肥,改善土壤结构;四是强化水分管理,小麦头水在二叶一心到三叶一心期浇灌,每隔15d左右灌水一次,促进有效分蘖;
It was learned from the Gansu Provincial Department of Agriculture and Animal Husbandry that the average yield of 10,000 mu of high-yielding spring wheat in Yumen reached 9 979.5kg / hm2. This yield is the highest record of the current high-yielding demonstration of producing spring mu wheat in spring. Integrated innovation and precision management are the main measures for establishing high-yielding spring wheat in Yumen. The first is to determine the dominant varieties. The project area takes Liushun No.3 as the leading species, demonstrating and popularizing new varieties such as 92157 and Longchun No. 24, Sowing amount of about 10cm when the soil top Ling sowing, seeding rate of 375 ~ 487.5 kg / hm2; third is the scientific operation of fertilizer, organic fertilizer applied plow autumn, deep turn after full maturity, combined with top dressing to improve the soil structure; Is to strengthen the management of water, wheat head water in the two leaves one heart to three leaves a heart irrigation, irrigated once every 15d, to promote effective tillering;
