特用玉米品种筛选与配套栽培技术研究

Selection and Cultivation Technique System of Special Purposed Corn

1998年从全国各地引入144个特用甜、糯玉米品种,在北京农业职业学院实训园进行种植,进行物候期观察及地区适应性的鉴定,从中筛选出适应北京种植的甜玉米2个、花糯玉米2个、白糯玉米3个。1999年对7个品种进一步进行品比试验,筛选出产量高、品质好的优良玉米品种秦龙甜一号和花香糯一号。2010年进一步对花香糯一号进行密度及肥料试验,确定最佳种植密度为52 500株/hm2、最佳底肥施用量为187.5 kg/hm2。

Field experiment with 144 special purposed sweet and waxy corn lines introduced from all over China was conducted in Beijing Vocational College of Agriculture in 1998.The phonological observation and adaptation identification of the corn hybrids were completed at their growth period.Consequently,2 sweet corns,2 mixed waxy corns and 3 white waxy corns hybrids fitting to cultivation in Beijing were selected.In 1999,further comparative experiment of these 7 varieties was conducted.As the result,sweet corn Qinlong 1 and waxy corn Huaxiang 1 of high productivity and fine quality were selected.In 2010,planting density and fertilizer test on the waxy corn Huaxiang 1 was conducted and the results were as follows：the most appropriate planting density was 52 500 plant/hm2 and 187.5 kg/hm2 of complex fertilizer as base manure.
