摘要
选取湖南省推广面积较大的9个玉米品种,在湘潭县采用随机区组设计,比较不同类型玉米品种对光、温、水资源利用效率的差异。结果表明,产量高于7500㎏/hm^(2)的品种对光、温、水资源的利用效率更高,说明玉米高产与光、温、水资源的利用密切相关。从产量和资源利用效率上看,渝单58、双玉919和湘康玉7号等中晚熟、非耐密类型品种在湘中地区推广较好。但考虑到与大豆、甘薯等作物间作或套种,或与晚稻连作等季节紧张的种植模式,中玉335等中熟、较耐密类型以及沣玉1号等早熟或早熟偏迟耐密类型玉米品种也可推广。
A random block design was used in Xiangtan County of Hunan to compare the difference of light,temperature and water use efficiency of 9 maize varieties.The results showed that the varieties with a yield of more than 7500㎏/hm~2 had higher utilization efficiency of light,temperature and water resources,indicating that the high yield of maize was closely related to the utilization of light,temperature and water.In terms of yield and resource utilization efficiency,the middle-late maturity and non-density tolerance types such as Yudan 58,Shuangyu 919 and Xiangkangyu7 had been well applied in the central of Hunan.However,considering the planting patterns of seasonal stress,such as intercropping or inter planting with soybean and sweet potato,or continuous cropping with late rice,Zhongyu 335 and Fengyu 1 can also be used.
