Eng . ) 1 . know the fertilizers ( the appearance , properties , physical and chemical nature which includes the organic and inorganic fertilizers ) ; 2 . determining the quality ( three major elements of the fertilizers ) and quantity ( the content of the moisture , nitrogen , phosphorus , and potassium ) of chemical fertilizer ; 3 . the fertilizer composition expresses and calculation of the amount of application ; 4 . it is cultivated in a pot or nutrient solution to test fertilizer effects ; 5 . observe plant body : besides observing one ' s own test cultivated in a pot , and another diagnose the picture is for comparing ; 6 . making of the compost 中) 1 .认识肥料(包括有机、无机肥料的外观、性状、理化性质) ； 2 .化学肥料的定性(肥料的三要素)及定量(水分、氮、磷、钾的含量)检定； 3 .肥料成分表示方法及肥料施用量的计算； 4 .盆栽试验或水耕试验(印证报酬渐减率、麦氏理论或肥料元素缺乏徵状，并进行农艺性状调查) ； 5 .植体观察：除了观察自己的盆栽试验以外，另备有诊断图片以供比较； 6 .有机堆肥的制作。

The basic fertility characteristics , and soil microbes and the relationship between them were investigated on paddy fields of purple soil , where no - tillage and ridge culture had been practiced for twelve years . the advantages and disadvantages were contrasted among five culture modes ( conventional culture , no - tillage and fallow in winter , no tillage and ridge culture , no - tillage and box culture , and the rotation of paddy and upland ) 通过对12年免耕的稻田的土壤微生物和基本肥力特征研究，找出二者之间的关系，指出免耕耕作方式养分增加、肥力提高的主要原因是作物秸秆的加入以及免耕改变了土壤的水、热、气、肥条件，并因此而探索影响秸秆分解的因子，找出微生物种类和有机、无机肥料的更好搭配。
