- 摘要:
- 为解决巴州地区饲用草料短缺、品种单一问题,以青贮玉米(金刚青贮50、KWS7340)为对照,引进8个甜高粱品种,在巴州轮台县和焉耆县分别采取随机区组试验,对农艺性状、营养品质及产量进行比较,并对结果进行相关分析和隶属函数分析。结果表明,在轮台县试验点,8个甜高粱品种的综合评分高于对照,均适宜在轮台县复播。在焉耆县试验点,辽甜13、新9、济甜杂2号和大力士4个甜高粱品种综合评分高于对照,适宜在焉耆县复播。甜高粱复播后产量、品质、收益均优于对照,可以在轮台和焉耆县进行复播替代青贮玉米作为饲料推广应用。
- Abstract:
- In order to solve the problem of the shortage and single variety of forage grass feed in Bazhou Area,eight sweet sorghum varieties were introduced,and the Luntai County and Yanqi County of Bazhou were used as randomized block experiment to study the agronomic traits,nutritional quality and yield,the silage maize (Jingang 50,KWS7340) used as the control group. Correlation analysis and membership function analysis were employed to analyze the results of experiment. The results showed that the comprehensive scores of eight sweet sorghum varieties in Luntai County were higher than the control,which suitable for replanting in Luntai County. The comprehensive scores of Liaotian 13,Xin 9,Jitianza 2 and Dalishi were higher than the control in Yanqi County,indicated that those four varieties were suitable for replanting in Yanqi County. The yield,quality and income of sweet sorghum after multiple cropping were better than control maize,which can be popularized and applied in Luntai County and Yanqi County as an alternative feed for silage maize.
