【摘要】 为探索沧州生态类型区青贮玉米种植和经济效益,通过豫青贮23与郑单958田间比较试验,研究其生物产量与经济效益。结果表明:豫青贮23平均鲜重产量60 240 kg·hm-2,干物率26.08%,平均干重产量15 720 kg·hm-2,郑单958平均鲜重产量52 380 kg·hm-2,干物率27.49%,平均干重产量14 400 kg·hm-2,豫青贮23比郑单958鲜重增产15.01%,干重增产9.17%,平均增收约2 400元·hm-2,豫青贮23经济效益较郑单958明显提高。
【Abstract】 In order to explore silage maize planting and economic benefit in the ecological type area of Cangzhou,the plant weight and economic benefits were studied through field comparison experiment of Yuqingzhu 23 and Zhengdan 958.The results showed that the average fresh weight and dry weight yield of Yuqinzghu 23 were 60240 kg·hm-2 and 15 720 kg·hm-2,respectively,and the dry matter rate was 26.08%.The average fresh weight and dry weight yield of Zhengdan 958 were 52 380 kg·hm-2 and 14 400 kg·hm-2,respectively,and the dry matter rate was 27.49%.The fresh weight yield of Yuqingzhu 23 was 15.01% higher than that of Zhengdan 958,and the dry weight yield was increased by 9.17%.The average income was about 2 400 yuan·hm-2,the economic benefit of Yuqingzhu 23 was significantly higher than Zhengdan 958.
