【摘要】 通过三年多点小区试验和大面积示范推广,结果表明,杂交玉米在福建省的春、夏、秋三季都能种植;以大豆、花生、甘薯等矮秆作物为主作物与玉米高秆作物间作,复合群体产量和产值比单作增加15%以上的最佳种植方式为;主作物保持与单作时同样的播种面积和最佳密度,隔沟沟底间作玉米1400株/亩;秋播玉米单作亩产350公斤以上的高产配套技术措施为:因地制宜于7月25日—8月5日间适时早播,每亩基本苗5000—5500株,施氮素10—12公斤,基肥、拔节肥、穗肥的比例为3:3:4.更多还原

【Abstract】 More than 3 years experiments in multiple plot and demostrative popularization on a large scale show that hybrid corn can be planted in Fujian in Spring, Summer and Autumn; the best planting method for 15 percent increase in yield and value by compound colony of main crops as soybeans , peanut and sweet potato and intercrops as corn is: main crop keeping planting areas and optimum density, intercrop corn in furrow drilling 1400 plant/mu; high yield technical measures for single cropping of more than 350 kg in Autumn sowing; sown between July 25 to August 5, basic seedlings per mu 5000 - 5500, fertilizing nitrogen 10-12 kg-on an average of top application of jointing and spike fertilizer.更多还原
