研究水稻旱作可以充分发挥旱耕地的潜力,减少耕地水分对稻作的影响作用,是进一步扩大我省稻作栽种面积,增加稻作产量的重要而有效途径。试验布置于贵州农学院教学实验农场分场黄壤坡地上,海拔1200米,地面坡度4度,土壤质地为轻粘土,土壤肥力中等,小区试验地全氮含量0.149％、全磷0.029％、有机质3.52％、水解氮14.12mg/100土,速效磷8.21ppm、速效钾3.53mg/100土、pH值6.18. Research on dry farming of rice can give full play to the potential of dryland and reduce the impact of cultivated land moisture on rice, which is an important and effective way to further expand rice planting area and increase rice production in our province. The experiment was arranged on the ground of yellow soil slope of Guizhou experimental farm, which was 1200 m above sea level with the slope of 4 degrees on the ground. The soil texture was light clay and the soil fertility was medium. The total nitrogen content was 0.149%, the total phosphorus content was 0.029%, the organic matter content was 3.52 %, Hydrolyzed nitrogen 14.12 mg / 100 soil, available phosphorus 8.21 ppm, available potassium 3.53 mg / 100 soil, pH 6.18.
