| 摘 要： | 田间试验采用"3414"方案设计。在沈阳市不同土壤肥力上共布置了37个试验点,根据作物产量分为高产、中产、低产区,不同产区设计不同施肥水平。试验表明:大部分试验点的施肥水平设计是科学的,可为当地推荐施肥提供依据,同时对多点试验结果进行统计分析,以获得区域测土施肥参数;各种参数不一定是定值,但有规律可寻,如最高产量施肥量、最佳经济施肥量虽不是定值,但多数试验结果都在一定范围内浮动;试验得出土壤肥力、土壤有效养分较正系数、肥料利用率与土测值之间的关系,这些为沈阳市测土配方施肥提供了科学依据。

| Abstract: | In this research,37 test points including high yield,medium yield,low yield were selected using the "3414" plan,the results showed that: the fertilization level adopted were scientific and reasonable;the experimental determination results were analyzed for get-ting the fertilizing parameters that were not fixed value but has rule such as the fertilization of maximum yield;the relation of the opti-mum economical fertilization,the correction coefficient of fertility,available nutrient,fertility utilization an... |
