无公害玉米生产相关技术研究

本试验在玉米产业化较好的阿城市,围绕无公害玉米标准化生产中的品种、农药、肥料问题,进行了详尽研究.筛选出适于当地种植且加工性状较好的常规玉米新品种龙单25、哈丰1号、龙单30、金玉3号,糯玉米品种龙粘1号、克粘1号、庆粘1号等.利用白僵菌防治玉米螟效果较显著,防治效果达到81.4%.有机生物肥试验中几个肥种较施用无机肥产量略低,减少幅度在0.7%～4.4%之间,是在允许范围之内[1].施肥水平试验提出了在当地施用复混肥、有机肥的合理用量.

Studies on Related Technique of Nuisance Free Maize Production

The test was carried on with a view of the variety,insecticide and fertilizer while standardizing the nuisance free maize production in maize industrialization highly developed city Acheng.Better processing character ordinary maize varieties Longdan 25,Hafeng 1,Longdan 30,Jingyu 3,Glutinous maize variety Longnian 1,Kenian 1,Qingnian 1 were chosed.Fungus was used to prevent maize moth and the prevention effect was up to 81.4%.Although the yield of organic bio-fertilizer was slightly lower than that of inorganic fertilizer,but the range was allowed by 0.7%~4.4%~().Experiment of fertilizer level supplied with the rational amount of organic bio-fertilizer and fertilizer mixture for the local fertilizer level.
