The result shows that: a positive correlation is found between the amount of application of chemical fertilizer and some factors, such as farming hours, attitude towards risks, total family incomes and the proportion of agricultural labour and non-agriculturallabour. A negative correlation is found between the amount of application of chemical fertilizer and other factors, such as farmers' educational background, their cognition of chemical fertilizer, and the channel of information. The agricultural incomes and planting areas seem to be not notable inflecting factors.

研究结果表明：户主的从农时间、风险态度、农户家庭总收入、以及劳力与非农比例情况对农户施肥量成正向相关关系；户主的教育程度、农户对于化肥的认知情况、信息渠道、施肥方式、是否施用有机肥、农户对于化肥利用率的认知以及农户对于污染认知程度等因素对农户施肥量成负向相关关系；农业收入和种植面积的影响则是不显著的。

The ammonia volatilizing of fertilizer is suit to the dynamic equation as Y=a+bt, the coefficients in the equation are related to the kind of fertilizer, temperature and water content of soil, and the dynamic equation about ammonia volatilization including water and temperature and the is developed. In addition, the dynamic equation about ammonia fertilizer affected by interaction of water and temperature is gotten.

肥料氨累积挥发量符合零级反应动力学方程Y=a+bt，方程中系数与肥料种类、温度和土壤含水量有关，碳铵a、b值均比硫酸铵高，土壤含水量增大，a、b值降低，温度升高，a、b值增大，并由此得到含温度或土壤湿度因子的肥料氨挥发动力学方程，并建立了含水、热因子的肥料氨挥发水热耦合效应动力学方程。

The content of nitrate in the leaves in treatment 1 and the treatment with 50% white clover plus little ammonium sulphate as base fertilizer were lower and the soluble sugar higher than that in other fertilizer treatments, which indicated that the B. chinensis quality in that both treatments were superior to pure chemical fertilizer treatments.

同等氮量下，基肥全部用白三叶的处理，生菜的株高、叶宽、叶片数、地上部鲜重和地下部鲜重均显著高于对照，基肥减少50％白三叶用量的处理在追肥前生菜的生长与对照相比无显著差异，追施复合肥后生菜生长显著优于对照，株高、叶宽和地上部鲜重显著优于基肥全部用白三叶的处理。

The fertilizer test base on three aspect of grain size、growth velocities 、rate of the green parts, the result present that IBDU multiple fertilizer is bigger grain size and quirkier hydrolyze rapid and more short release period than UF multiple fertilizer, which work easier burning spot on grass leaf of Green lawn; on aspect of growth

肥料对比试验中，进行了颗粒大小、生长速度和绿叶率变化等三个指标的测试，结果指出IBDU技术肥料相对UF技术肥料在沙土环境中具有水解速度快，养分释放周期短等特点，并且大颗粒的IBDU技术肥料容易在水解过程中对果岭草坪产生灼烧性斑点，而对比试验使用的UF技术肥料由于粒径较小相对克服了此点不足；在生长速度和绿叶率变化方面，IBDU果岭均提前于UF果岭达到生长高峰和全绿率，也提前下降生长速率和绿叶比值，试验最终IBDU果岭的日生长量和绿叶率均明显低于UF果岭的数值。
