甜玉米新品种庆甜1号栽培模式研究

Studies on the Cultivated Method of Qingtian 1 Sweet Corn Variety

对“庆甜1号”进行了肥效、密度及分期栽培试验,结果表明,正常条件下地膜覆盖种植“庆甜1号”经济合理的氮、磷施用量为N 105 kg/hm2、P2O575 kg/hm2;45 000 kg/hm2农家肥和磷肥一次性基施,氮肥的2/3作种肥,1/3作追肥施用方式较为经济合理;最佳种植密度为67 500株/hm2;早春小拱棚育苗移栽和油菜茬复种两种种植模式宜在当地大面积推广,麦茬复种适宜在当地南部川道地区推广。

The tests of the fertilizer effect, density and different growth stages of Qingtian 1 were carried out. The results indicated that applying 105 kg/hm^2 nitrogen and 75 kg/hm^2 phosphorus fertilizer is the most economic and rational method; applying 45 000 kg/hm^2 farm manure with phosphorus as base fertilizer, two thirds nitrogen as seed manure and one third nitrogen as topdressing is more economic and rational; the best planting density is 67 500 plant/hm^2 ; the transplanting style after growing seedlings in small arch greenhouse in early spring and the multiple cropping style after rape harvesting should be extended over large areas;the multiple cropping style after wheat harvesting should be extended in the southern rivers rigions of this locality.
