摘　　要：为了明确土壤调理剂在改良设施土壤理化性状及增加作物产量方面的作用,确定土壤调理剂产品的最佳施用量,便于在农业生产中的应用推广,笔者研究了土壤调理剂对设施菜田（以北京市房山区为例）土壤性状及农作物生产的影响。结果表明：施用土壤调理剂对提高设施土壤田间持水量、土壤阳离子交换量及番茄产量作用明显,土壤调理剂施用量与土壤田间持水量、阳离子交换量及番茄产量的关系分别可以用方程y=-8×10^-5x2＋0.0329x＋27.34（R2=0.958）,y=-0.0004x2＋0.0639x＋16.39（R2=0.9344）和y=-0.0041x2＋＋0.5155x＋77.725（R2=0.9877）拟合。土壤调理剂施用量60~75 L/hm2对改善土壤理化性状、增加番茄产量最优。In order to clarify the function of soil conditioner on improving soil physical and chemical characteristics and increasing crop yield and determine the best application rate to extend in agricultural production, the author took Fangshan District of Beijing as an example to study the effect of applying soil conditioner on soil properties and crop production in facility vegetable fields. The results showed that： the application of soil conditioner on the facilities field would improve apparently the soil field capacity, soil cation exchange capacity （CEC） and the yield of tomato, the relationship between the amount of soil conditioner and the soil field capacity, soil cation exchange capacity （CEC） and tomato yield could be fitted with the equations of y=- 8 × 10^- 5x2 ＋ 0.0329x ＋ 27.34 （R2=0.958）, y=- 0.0004x2 ＋ 0.0639x ＋ 16.39 （R2=0.9344） and y=- 0.0041x2 ＋ 0.5155x＋77.725 （R2=0.9877）. Therefore, the best application amount of soil conditioner was 60-75 L/hm2.
