唐山地区青贮玉米种植中荧保素应用技术研究

为探索唐山生态类型区青贮玉米种植中荧保素拌种技术应用的可行性,以沃玉3为材料,通过田间比较试验,研究了荧保素对青贮玉米生物产量与经济效益的影响。结果表明,荧保素拌种处理的鲜生物产量55 695kg/hm^2,干生物产量17 472 kg/hm^2,干物质率31. 37%,对照鲜生物产量50 235 kg/hm^2,干生物产量16 532kg/hm^2,干物质率32. 91%,拌种较对照鲜生物量增产10. 86%,干生物量增产5. 71%,平均每公顷增收约1750元,经济效益显著提高。建议在唐山生态类型区青贮玉米种植中推广应用荧保素拌种技术。

Study on the Application of Pseudomonas Fluorescent in Silage Corn Planting in Tangshan Area

The plant weight and economic benefits were studied through comparative experiments between seed mixing and control field of Woyu 3 in order to explore the feasibility of seed mixing technology of fluorescent in silage corn planting in the ecological type area of Tangshan.The experimental results showed that the fresh weight yield and dry weight of seed mixing technology of pseudomonas fluorescent was per hectare 55 695 kg and 17472 kg,respectively,and the dry matter rate was 31.37%.The fresh weight yield and dry weight of control was per hectare 50 235 kg and 16 532 kg,respectively,and the dry matter rate was 32.91%.The seed mixing increased by 10.86% compared to the control fresh weight,and the dry weight increased by 5.71%.The average increase in income per hectare was about 1750 yuan,and the economic benefits were significantly improved.It was initially proposed to promote the application of pseudomonas fluorescent in silage corn planting in the Tangshan ecological type area.
