Screening Experiment of Different Maize Varieties under Full Biodegradable Mulch Cultivation in Semi-arid Areas of Huining
摘要
Abstract
In order to screen out drought-resistant,high-yielding and high-quality maize varieties in the semi-arid areas of Huining so as to provide a scientific basis for transitioning from traditional plastic mulch to fully biodegradable mulch film cultivation,this study took 11 drought-resistant maize varieties as experimental materials,and utilized fully biodegradable black mulch film and full-film double-monopoly cover furrow sowing technology to determine and analyze maize growth period,agronomical traits,yields,SPAD values,and quality indexes.Results showed that under the planting density of 60 000 plants/ha,the highest yield was recorded for Xianyu 1483(9 584.1 kg/ha),followed by MC703(9 147.8 kg/ha)and Dika C1563(8 987.2 kg/ha),and the growth period was 127 d for Xianyu 1483,MC703 and Dika C1563.The SPAD values of the leaves of Xianyu 1483,MC703 and Dika C1563 were 55.7,56.5 and 52.3,respectively,during the grain-filling stage,which showed stronger photosynthetic capacity and better nutritional quality of the integrated grains in the late stage.In conclusion,the three varieties of Xianyu 1483,MC703 and Dika C1563 performed the best,and can be used as demonstration varieties in the semi-arid zone of Huining under the all-biodegradable film ridging planting mode.关键词
