| 摘 要： | 采用4因素二次回归正交旋转组合设计,对杂交玉米黔单19号在黔西北山区的高产配套栽培技术模式进行了研究.结果表明,试验因素对黔单19号产量的影响程度为密度＞N＞K2O＞P2O5,合理密植,增施氮、磷、钾肥是实现该品种高产的重要技术措施.该品种在黔西北山区产量超过650 kg/667m2的综合栽培技术措施为种植密度3 645～3 883株/667m2,纯氮21.17～24.20 kg/667m2,P2O5为 16.35～21.33 kg/667m2,K2O为14.91～17.78 kg/667m2. |

| Abstract: | A set of cultivation technique for high yield of Qiandan 19,a new hybrid maize variety,was established by the quaternary quadratic regression orthogonal rotational combination design in Bijie prefecture.The results showed that the factor of affecting its yield was density >N>K2O>P2O5 and the important technical measure for its high yield was rational density and increase of N,P and K application amount.The comprehensive cultivation technical measure for over 650kg/667m2 of Qiandan 19 is 3645 to 3883plants/6... |
