稀植大穗型玉米品种的品比试验

通过对13个稀植大穗品种的品比试验研究,得出了在山西北中部不同生态区如何选择、推广稀植大穗品种的结论:山西北中部平川区高水肥地宜推广种植忻玉106、晋单48号、新45、天塔1号;丘陵旱作区宜推广种植晋单48号、大丰2号、农大364、强盛12号、泽玉4号;在利用秸秆贮青的养殖区宜选用天塔1号、新45,可以粮饲兼顾,收益更高;生产玉米用于加工淀粉可选用晋单48号;连续种植玉米的地块慎选沈单16号、大丰2号、强盛17号、晋单45号、泽玉4号,避免感染丝黑穗病而造成减产。

Comparative Experiment of Large-size Spike Maize Varieties under Lower Density Cultivation

Comparative experiment of 13 large-size spike maize varieties under lower density cultivation had been studied and a conclusion how to select and popularize large-size spike maize varieties under lower density cultivation had been got.The result is as follows: The appropriate variety should be planted in relevant area in middle north in Shanxi.Xinyu106,Jindan48,Xin45,Tianta1 should be planted in the area of high water manure and flat field;It is suitable that Jindan48,Dafeng2,Nongda364,Qiangsheng12,Zeyu4 are promoted and planted in the area of hill and drought;It is more effective if Tianta1 and Xin45 are selected in area of breeding livestock where the stalk is used as silage;Jindan48 should be planted in the area where the corn is used to process starch;In order to avoid infecting maize head smut,it is discreet that Shendan16,Dafeng2,Qiangsheng17,Jindan45,Zeyu4 are planted in the land where the maize was grown continuously.Otherwise it could result in reduction of output.
