摘要
在大田条件下,以尿素和不施肥作对照,研究了畜粪、菜籽饼、生物有机肥、硫酸镁钾等4种肥料、12个配比施用量对水稻病虫草的影响。试验结果表明,4种肥料、12个配比施用量对水稻纹枯病、二化螟、稻纵卷叶螟和稻飞虱具有较好的抑制和控制作用,对稻田杂草发生无影响。产量测定结果表明,早稻菜籽饼2250kg/hm2、菜籽饼1500kg/hm2、菜籽饼750kg/hm2、生物有机肥900kg/hm2处理和晚稻畜粪31500kg/hm2、菜籽饼2250kg/hm2、菜籽饼1500kg/hm2、生物有机肥900kg/hm2、生物有机肥600kg/hm2处理均增产效果显著,硫酸镁钾3个配比施用量无增产效果。
The effects of 4 fertilizers namely animal feces, rape cake, organic manure and sulphate of potash magnesia at 12 dosages on disease, insect pests of rice, and weeds in the paddy field were tested with the controls of urea and no fertilizer. The control effects of 4 fertilizers at 12 dosages on Rhizoctonia solani, Chilo suppressalis, Cnaphalocrocis medinalis and planthopper （Nilaparvata lugens and Sogatella furcifera） were better than urea treatment. They had no influence on weeds in the paddy field. The yield-increasing effects of rape cake 2250 kg/hm2, 1500 kg/hm2, 750 kg/hm2, organic manure 900 kg/hm2 treatments in the early rice and animal feces 31500 kg/hm2, rape cake 2250 kg/hm2, 1500 kg/hm2, organic manure 900 kg/hm2, 600 kg/hm2 treatments in the late rice were remarkable. Sulphate of potash magnesia at 3 dosages had no yield increasing effects.
