摘要
2002～2004年以小麦和玉米为试材,研究了多元复混肥对夏玉米和冬小麦农艺性状及产量的影响。结果表明,与三元肥处理比较,多元肥处理夏玉米提早抽雄2 d,秃顶长度短0.2 cm,单穗重高21 g,千粒重高8.5 g,减少金边叶和条纹叶病叶率;小麦成穗率高13.0%,穗数和穗粒数高,但千粒重差异不显著;小麦-玉米总产量高7.76%。主要原因可能与多元肥能够协调供应氮磷钾及微量元素营养有关。
The effect of muhy-fertilizer application on the characteristics and yield of maize and wheat was studied from 2002 to 2004. The result shows that the muhy-fertilizer can make maize early heading 2 days, increase the grain weight 21 grams per ear and resistant to disease. As for wheat it increase ear number and grain weight. The total effect increase 7. 76% of maize and wheat yield.
