青海东部农业干旱区6个饲用玉米品种生产性能的比较

COMPARISON OF PRODUCTION PERFORMANCE OF SIX FORAGE MAIZE VARIETIES IN THE EASTERN AGRICULTURAL AREA OF QINGHAI

为了筛选适合青海东部干旱地区高产饲用玉米品种,采用单因素随机排列,比较了6个饲用玉米品种生产性能和种植效益。结果表明:豫青贮23株高达288.62 cm,显著高于其他品种;豫玉22鲜草平均产量13.57×10^(4)kg/hm^(2),与豫青贮23和甘玉23平均产量间差异不显著;豫玉22盈利达1.60×104元/hm^(2),较豫青贮23和甘玉23分别提高16.79%和18.52%。从综合表现来看,豫玉22、豫青贮23和甘玉233个饲用玉米品种在青海东部干旱地区具有高产性能和较高的经济效益,值得大力推广应用。

In order to screen forage maize varieties suitable for high yield in the arid area of eastern Qinghai province,six forage maize varieties were selected by single factor random arrangement,and the production performance and planting efficiency among them were compared.The results showed that the height of 23 Yu silage plants reached 288.62cm,which was significantly higher than that of other varieties.The average forage yield of Yuyu 22 was 13.57×10^(4)kg/hm^(2),and there was no significant difference between the average forage yield of Yusilage 23 and Ganyu 23.The profit of Yuyu 22 reached 16,000 yuan/hm^(2),which was 16.79%and 18.52%higher than that of Yusilage 23 and Ganyu 23 respectively.According to the comprehensive performance,Yuyu 22,Yusilage 23 and Ganyu 23 forage maize varieties have high yield and high economic benefits in the arid area of eastern Qinghai province,and are worthy of popularization and application.
