| 摘 要： | 为揭示黑龙江西部半干旱区膜下滴灌栽培方式下玉米高产措施,以郑单958为材料,选取氮肥、磷肥、钾肥和密度四因素作为试验因素,每个试验因素设计5个水平,按照二次通用旋转组合设计(1/2实施)统计分析方法建立回归模型,分析不同肥料和密度组合对玉米产量的影响。结果表明:四因素各单因子对籽粒产量有较明显的影响,均呈开口向下的抛物线趋势变化,影响顺序为施氮密度施钾施磷,且单位水平施入量引起边际产量的减少量为施磷密度施钾施氮;氮肥与磷肥之间的配合对产量的增加具有相互促进作用;要获得≥12231.97 kg·hm~(-2)的产量,氮肥、磷肥、钾肥及种植密度的最优组合取值范围为:氮肥246.24~279.59 kg·hm~(-2),磷肥133.77~151.52 kg·hm~(-2),钾肥82.85~97.16 kg·hm~(-2),种植密度79 676~85 324株·hm~(-2)。

| Abstract: | To investigate the cultivation practices for high yield of maize under mulched drip irrigation in the semi-arid and cold areas in western Heilongjiang province ,maize variety Zhengdan 958 was used as the study material .In ad-dition ,nitrogen ,phosphate ,potash and planting density were selected as the four experimental factors ,each of which was tested at five levels .A quadratic regression model was thereby employed to establish in accordance with rotation de-sign statistical analysis methods (1/2 implement ) to analyze the effects of different fertilizers and planting densities on grain yield .The results showed that each single factor had obvious influence on grain yield ,exhibiting a trend of down-ward opening parabola .The effects of these four factors were in an order of nitrogen (N ) > density > potash (K ) >phosphate (P) .Also ,the marginal yield reduction caused by unit volume level applied was in a order of phosphate (P)> density > potash (K ) > nitrogen (N ) .Coordination between nitrogen and phosphate had a mutual promoting effect on the increase of grain yield .To achieve a yield higher than 12231 .97 kg·hm-2 ,the best combination of nitrogen and phosphate fertilizer ,potash fertilizer ,and planting density were as follows:246 .24~279 .59 kg·hm-2 nitrogen;133 .77~151 .52 kg·hm-2 phosphate;82 .85~97 .16 kg·hm-2 potash and 79 676~85 324 plants·hm-2 planting density . |
