摘要
针对吉林省榆树市部分农民在水稻施肥上存在重氮、轻磷、忽视钾的现状开展了测土配方施肥研究。试验结果表明,与当地习惯施肥相比,应用测土配方施肥技术可改善水稻主要经济性状,促进水稻健康生长,进一步提高水稻产量,增产增收效果显著。测土配方施肥比当地习惯施肥平均增产909kg/hm2,平均增收为1533元/hm2,增加了稻农的经济收入。
In view of present situation of heavy nitrogon, light phosphorus and neglecting potassium in paddy rice fertilization in Yushu city of Jilin Province, the formula fertilization by soil testing was studied. The results indicated that formula fertilization by soil testing could improve the main economic characters of rice, and promote the rice health growth, and also increase the yield. The effects of increaseing yield was remarkable. Compared with coventional fertilization, the yield of formula fertilization by soil testing increased by 909 kg/hm^2, benefit increased by 1 533 yuan/hm^2.
