摘要
以鲜食玉米品种金糯262和京科糯2000为供试品种,于2023年5-10月在黑龙江八一农垦大学农学院盆栽场进行盆栽试验。设置4个氮肥水平,分别为0(N0)、150(N1)、225(N2)、300 kg/hm^(2)(N3),研究不同施氮量对糯玉米主要营养品质及产量的影响。结果表明,金糯262适采期在吐丝后20~25 d,京科糯2000适采期在吐丝后20~30 d,金糯262在N1处理下达到优质高产,京科糯2000在N2处理下达到优质高产。因此,半干旱地区糯玉米采收应在吐丝后25 d左右最佳,同时150~225 kg/hm^(2)是适宜半干旱地区糯玉米种植的氮肥用量。
Using the fresh corn varieties Jinnuo 262 and Jingkenuo 2000 as test materials,a pot experiment was conducted at the pot cultivation field of the College of Agriculture,Heilongjiang Baiji Agricultural University,from May to October in 2023.Four nitrogen fertilizer levels were set,namely 0(N0),150(N1),225(N2),and 300 kg/ha(N3),to study the effects of different nitrogen application rates on the main nutritional quality and yield of waxy corn.The results showed that the optimal harvesting period of Jinnuo 262 was 20-25 days after silking,and that of Jingkenuo 2000 was 20-30 days after silking.Jinnuo 262 achieved high-quality and high-yield under N1 treatment,and Jingkenuo 2000 achieved high-quality and high-yield under N2 treatment.Therefore,the optimal harvest time for waxy corn in semi-arid areas is about 25 days after silking,and the suitable nitrogen fertilizer application rate for waxy corn cultivation in semi-arid areas is 150-225 kg/ha.
