| 摘 要： | 通过对湘南旱地玉米垄栽技术研究,结果表明:在旱地上实行垄栽,可以提高玉米叶面面积,叶面积指数比平栽增加12.9%。垄栽土壤含水量在玉米生长后期明显高于平栽土壤,玉米腊熟期,垄栽土壤含水量比平栽土壤含水量高出1.5%,增加8.2%。在玉米整个生育期中,垄栽耕层土壤有效氮、磷养分高于平栽,其增产率达20%以上。在湘南旱地上,采取垄栽种植是保证玉米增产的一项重要技术措施。

| Abstract: | The research was conducted on ridge planting of maize in southern Hunan Province. The results showed that ridge planting increased the maize leaf area, and the leaf area index of maize under ridge planting was higher than lfat planting 12.9%. Soil moisture at maize later growth stage under ridge planting was significantly higher than that of flat planting. Soil moisture content under ridge planting was higher than that of lfat planting 1.5%, increased by 8.2%. In the whole growth period of maize, the topsoil available nitrogen, phosphorus under ridge planting was higher than lfat planting. Ridge planting increased the yield of 20% compared with lfat planting. In dry land in southern Hunan province, take ridge planting was an important technical measure to increase maize yield. |
