【摘要】 采用二次回归正交旋转组合设计,对糯玉米皖单5号高产栽培的三项主要农艺措施进行田间试验。对数据利用电子计算机进行处理,得出数学栽培模式,并建立了模拟优化密度、氮肥和磷肥实施方案数学模型。结果表明:皖单5号种植密度为4408株/667m2;尿素为33.83kg/667m2;磷酸二铵为14.62kg/667m2,可获得258.37kg/667m2的产量。更多还原

【Abstract】 Based on orthogonal experiment of single or multiple factors, the field experiment for 3 main agronomy measures of Wan Dan No. 5 was carried combine design. The results showed that they greatly influenced yield of Wan Dan No. 5, and they were significant interactions between planting densities, amount of nitrogen and phosphate applied and application methods. The selective preference cultivation combination for yields over 258. 37Kg per 667m2 was: 4408 plants, application of 33.83Kg nitrogen and 14.62Kg phosphate fertilizer per 667m2.更多还原
