Drought Resistance Evaluation of Main Maize Cultivars in Western Region of Heilongjiang Province

为推广种植优良的玉米抗旱品种,继续保持黑龙江省玉米增产、高产和稳产的目的,对黑龙江省西部地区玉米主栽品种的抗旱性进行了深入研究,在抗旱棚内采用膜下滴灌技术控制水分,通过多项抗旱性指标的测定,采用模糊隶属函数法对其抗旱性进行综合评价。结果表明:确定相对抗旱性较强的品种为嫩单15、吉单27、嫩单18;中等抗旱品种为先玉696、先玉335、鑫鑫1号和誉成1号;相对抗旱性较弱的品种为益农玉10号、郑单958和丰禾7号。

In order to promote the cultivation of excellent drought resistant varieties of maize,continue to maintain the aim of increasing the yield,high yield and stable yield of maize in Heilongjiang province,the drought resistance of maize varieties in the western region of Heilongjiang province was studied.In the drought-resistant shed,the technology of drip irrigation under the film was used to control the water.Through the determination of several drought resistance indexes,the fuzzy membership function method was adopted to comprehensively evaluate the drought resistance.The results showed that the highly resistance varieties were Nendan15,Jidan27 and Nendan18,the medium resistance varieties were Xianyu696,Xianyu335,Xinxin1 and Yucheng1,the non-resistance varieties were Yinongyu10,Zhengdan958 and Fenghe7.
