对广西3个玉米新品种南校201、南校202和南枝205进行施肥量需求试验.结果表明,生产上宜优先使用南校201、南校205;种植南校201和南校205.施用N 270kg/hm~2 P_2O_5 90kg/hm~2,K_2O 240kg/hm~2,可获得最高的产量和最佳的经济效益;南校201抽雄至成熟天数多、叶面积系数大、穗粒数多;南校205群体内各层叶片能合理地接受光能、叶片的叶绿素含量高、千粒重大;不同施肥水平,对抽雄至成熟天数、叶面积系数、叶片叶绿素含量、穗位高、穗粒数和千粒重影响比较大.
對廣西3箇玉米新品種南校201、南校202和南枝205進行施肥量需求試驗.結果錶明,生產上宜優先使用南校201、南校205;種植南校201和南校205.施用N 270kg/hm~2 P_2O_5 90kg/hm~2,K_2O 240kg/hm~2,可穫得最高的產量和最佳的經濟效益;南校201抽雄至成熟天數多、葉麵積繫數大、穗粒數多;南校205群體內各層葉片能閤理地接受光能、葉片的葉綠素含量高、韆粒重大;不同施肥水平,對抽雄至成熟天數、葉麵積繫數、葉片葉綠素含量、穗位高、穗粒數和韆粒重影響比較大.

The different fertilizer levels in Guangxi three new varieties of corn Nanxiao 201.Nanxiao 202,Nanxiao 205 pi-lot study results showed that:the production of the school should be given priority in the use of Nanxiao 201,Nanxiao 205;cultivation Nanxiao 201,Nanxiao 205,application N 270 kg,P_2O_5 90kg,K_2O 240kg per hectare,the highest yield and the best value for molley;Nanxiao 201 tasselling more than the number of days to maturity,leaf area index,and number of grains per spike;Nanxiao 205 groups within the school leaf layer could reasonably accept the light,leaf chlorophyll content Was higher,the 1000-grain weight Was larger;different fertilization levels of tasselling time inpacted on the number of days to maturity,leaf area index,leaf chlorophyll content,ear height coefficient.grain number and weight relatively large.
