含硒腐植酸复合肥在玉米、大豆和水稻上的应用研究

EFFECT OF THE SELENIUM-CONTAINING HUMIC ACID COMPOUND FERTILIZER ON THE YIELD OF MAIZE, SOYBEAN AND RICE

在玉米、大豆和水稻上试用不同剂量的亚硒酸钠和含硒腐植酸复合肥．结果表明，含硒腐植酸复合肥能显著提高３种作物籽粒的产量和硒含量，是一条低成本高效益的增硒途径．

Diffetent dosages of sodium selenite and selenium-antaining humie acid compound fertilizer were applied for two years to study their effect on grain yield and selenium content in maize,soybean and rice. It was showed that the compound fertiliazer increased the yield and selenium content of grain in these crops with low cost and high profit.
