摘要
本研究选取干旱半干旱气候条件下庄浪县的不同地区,以粮饲兼用玉米品种富农1号为对照,对引进的垦玉90号等9个优质粮饲兼用玉米新品种进行分组比较试验,并连续两年推广种植,研究结果表明:五谷568号和垦玉90号生育期适中,山川适宜种植,综合经济性状好,丰产性强,籽粒产量、青贮产量分别较对照增长11.59%、22.77%和18.09%、22.36%;两年推广种植期间,籽粒、青贮均产较试验产量稳定率分别达88.97%、90.02%和90.00%、90.80%,可作为粮饲兼用玉米主栽品种适宜于在全县以至类似气候条件地区大面积推广种植。金凯7号抗旱、耐寒,籽粒产量、青贮产量分别较对照增长了8.11%、13.59%,两年推广种植期间,籽粒、青贮均产较试验稳产率达85.37%、91.82%;山区优势明显,适宜于在干旱、阴寒山区肉牛主养区作为饲草玉米种植。饲宝1号秸秆产量、青贮产量分别较对照增长9.94%、5.96%,两年推广种植期间,较试验青贮稳产率达92.14%,可作为饲草青贮原料主栽品种,适宜于在全县以至类似气候条件的肉牛饲养区地区大面积推广种植。
In this trial, thisresearch selected different regionsin arid and semi-arid of Zhuanglang county, using Funong 1 asthe control, a grain and forage corn breed, and nine new introduced varietiesof corn, including kenyu 90 were compared in groups and extended for two years.The resultsshowed: Wugu 568 and Kenyu 90 have the moderate growth period.They have better comprehensive traits, and compared with the control , the yield grain and corn silage increased by 11.59% and 22.77% for Wugu 568, 18.09% and 22.36% Kenyu 90, respectively.During the two-year extension planting period, the stable production ratesof grain and corn silage are 88.97% and 90.02% for Wugu 568, 90.00% and 90.80% for Kenyu 90, respectively, compared to the control group.They are suitable to extend in Zhuanglang or the same climate areas.Jinkai 7 isdrought and cold- resist.The yield grain and corn silage increased by 8.11% and 13.59%, respectively, compared to control.During the two-year extension, yield stable ratesof grain and corn silage are 85.37% and 91.82%, respectively, compared to control.It is suitable to extend in mountainousareas.The yield of straw and silage for sibao 1 increased 9.94% and 5.96% respectively, compared to control.During the two-year extension, yield stable ratesof silage is92.14 %.It issuitable for the whole county and similar climatic conditionsof beef cattle feeding areasto promote the cultivation.
