洛江区水田土壤养分现状及施肥建议

依托测土配方施肥项目,采集泉州市洛江区水田土壤进行养分测定,结果表明：全区水田土壤以酸性和微酸性居多,有机质含量属于中上水平,碱解氮含量中等,有效磷含量丰富,速效钾含量偏低;土壤交换性钙总体属于中上水平,有效硫、有效硼缺乏,交换性镁、有效锌缺乏和中等丰富的比例各占一半;土壤保肥供肥能力弱.并据此提出土壤改良及培肥措施.

Nutrient status in paddy soil of Luojiang District and fertilization recommendation

Supported by the project of soil testing and fertilizer recommendation, the nutrient status in paddy soil of Luojiang District, Quanzhou was determined. The results showed that the paddy soil in whole district occurred mainly acidity and slight acidity ; content of organic matter was at higher-medium level, available nitrogen was at medium, available phosphorus was sufficient, available potassium was slightly deficient, soil exchangeable calcium was basically at higher-medium level, a- vailable sulfur and boron were deficient, exchangeable magnesium and available Zn in the soil which at deficient level or higher-medium level occupied equal ration; weak capacity in fertilizer supplication and preservation. Based on the status, some measures for soil modification and fertility improvement were put forward.
