昌吉州滴灌条件下粮饲玉米品种引进筛选试验

Introduction and Screening of Grain and Feed Maize Varieties under Drip Irrigation in Changji Prefecture

采取随机区组设计,选取25个近年表现较优且通过国家审定、自治区审定的粮饲兼用的玉米新品种,测定其在肥料投入一致条件下的生育期、收获籽粒含水率和产量,以期筛选出为开展滴灌条件下适宜昌吉州种植的高效高产粮饲兼用玉米品种。结果表明,通过试验筛选出7个具有优势的玉米品种,分别是隆平781、隆平937、隆平943、同路213、同路212、华皖267、隆平678,平均产量在14999.00 kg/hm 2以上。从适应性来考虑,这7个品种适合在南北疆2300~2700℃积温区域以及在昌吉州乌伊路以南的半戈壁半山区半冷凉区域推广种植。

Randomized block design was designed to select 25 approved maize varieties for both food and feed in recent years.The growth period,rain moisture content and yield were measured under the same fertilizer input,so as to screen high efficiency and high yield corn varieties suitable for planting in Changji prefecture under drip irrigation.Results showed that seven maize varieties with advantages were screened out by experiments,which were Longping 781,Longping 937,Longping 943,Tonglu 213,Tonglu 212,Huawan 267 and Longping 678.The average yield of these maize varieties were more than 14999.00 kg/hm 2.In terms of adaptability,they were suitable for extended planting in 2300-2700℃accumulated temperature area in northern and southern Xinjiang,as well as semi-cold and cool area in semi-Gobi mid-level mountains south of Wuyi Road in Changji Prefecture.
