摘要
介绍了盐源县玉米超高产主要技术措施,通过相应配套技术措施创造了经专家验收平均单产18 270.0 kg/hm2的西南地区高产纪录,取得了667 hm2高产示范片平均产量10 691 kg/hm2的效果。指出攀西地区尤其是盐源、喜德等地具有创高产纪录的条件,采用以"缩行增密增穗、规范盖膜移栽、配方施肥"为关键的玉米种植技术能大幅度提高玉米产量水平,同时在优化栽培技术的前提下玉米产量还有望提升。
The techniques for maize super-high yield in Yanyuan county were introduced.The average yield of maize could reach to 18 270.0 kg/hm2,which created the high yield record in the region of southwest China,and the average yield could reach to 10 691 kg/hm2 in 667 hm2 demonstration planting region when adopting these techniques.Besides,it was pointed out that Panxi,especially Yanyuan and Xide had the condition of creating high yield,and the yield could increase significantly when adopting the techniques of reducing the row space for increasing planting density and the number of ear,tectorial transplanting,and the formula fertilization,especially when matched optimal cultivation technique.
