在早稻上进行施用高美施活性肥、复混肥和复合肥试验研究 ,结果表明 :高美施活性肥对早稻生长发育具有显著的促进作用 ,大米外观、口感等得到改善 ,且增产幅度大 ,经济效益好 ,肥料生产率高。施用高美施活性肥稻谷产量达 60 15kg/hm2 ,比对照增产 5 6.0 % ,产投比为 1.863。龙眠山牌复混肥和俄罗斯复合肥也有一定的增产效果 ,分别比对照增产 47.9%和3 0 .0 % ,产投比为 1.845和 0 .816。 The experiment of applying high active compound fertilizer, compound fertilizer and compound fertilizer on early rice was carried out. The results showed that high active compound fertilizer could promote the growth and development of early rice, the appearance and taste of rice were improved, and the rate of yield increase Good economic returns and high fertilizer productivity. The rice yield of 60 mg / hm2 was increased by 55% compared with the control, and the production / investment ratio was 1.863. Long Mianshan brand compound fertilizer and Russian compound fertilizer also had some stimulation effects, which increased 47.9% and 30.0% respectively over the control and the ratio of production to investment was 1.845 and 0.816.
