水稻施用镁肥和硼肥的效应研究

THE STUDY OF TIlE EFFCTS OF APPLYING MAGNESIUM FERTILIZER AND BORON FERTILIZER ON RICE

于1989年对广西宾阳县大桥乡大程村七星垌的渍害田进行增施镁肥、硼肥的肥效试验。结果表明:在每亩施用纯N 7.5 kg,P_2O_5 4 kg,K_2O 6 kg的基础上用0.05%的硼砂(Na_2B_4O_7·10H_2O)浸种8 h,并增施镁肥(MgSO_4·7 H_2O)2.5 kg/亩,获得明显的增产增收。与对照相比,杂交稻每亩增产57.38 kg,增15.57%,增收44.98元,增27.7%。而常规稻,与对照比,每亩亦增产35.64 kg,增10.26%;增收31.94元,增21.34%。经显著性检验,增产增收均达到极显著水平。

Magnesium fertilizer and boron fertilizer were applied to waterlogged paddy soils in Qi Xing Dong, Da Qiao commune, Bin Yang counntv, Guangxi in 1989. The results showed that yield of rice increased obviously by applying the magnesium fertilizer and the boron fertilizer on the basis of applying proper amount of nitrogen,phosphate and potassium fertilizers. The increased rice yield and the net income reached very significant level compared with contrast: the per mu yield of hybrid rice increased 57.38 kg or 15.57 percent, and the per mu net income increased 44.98 yuan or 27.7 percent; the per mu yield of common rice increased 35.64 kg or 10.26 percent, and the per mu net income increased 31.94 yuan or 21.34 percent.
