摘要
通过田间试验研究自主研制的钾硅钙微孔矿物肥在水稻上的应用效果,选择黑龙江虎林、内蒙古赤峰、山东济宁、贵州凤岗和广东增城5个试验点,设置不施肥、常规施肥、常规施肥＋钾硅钙微孔矿物肥450 kg.hm-2、常规施肥＋钾硅钙微孔矿物肥900 kg.hm-2、常规施肥＋钾硅钙微孔矿物肥1 350 kg.hm-25个处理,结果表明,与当地常规施肥相比,加施钾硅钙微孔矿物肥能够增加水稻产量,平均增产幅度达到7.6%,增收为68-3 120元.hm-2。基于产量和效益的分析,以450 kg.hm-2钾硅钙微孔矿物肥为最佳经济施用量。
Field experiments were carried out in Hulin of Heilongjiang,Chifeng of Inner Mongolia,Jining of Shandong,Fenggang of Guizhou and Zengcheng of Guangdong.5 treatments were designed,i.e.no fertilizer,conventional fertilization,conventional fertilization＋microporous potassium-silicon-calcium mineral fertilizer at 450 kg·hm-2,conventional fertilization ＋ microporous potassium-silicon-calcium mineral fertilizer at 900 kg·hm-2,conventional fertilization ＋ microporous potassium-silicon-calcium mineral fertilizer at 1 350 kg·hm-2,for the study of effect of microporous mineral fertilizer,a national invention patented product,on rice growth and yield.Results show that the new fertilizer increased yield by 7.6% on average,and economic income by the range of 68-3 210 Yuan·hm-2,as compared with the conventional fertilizers.Considering its effect on rice yield and economic benefit,the optimal economic application rate is recommended to be 450 kg·hm-2.
