有机肥和土壤调理剂在蔬菜上的应用效果试验

Application of Organic Fertilizer and Soil Conditioner on Vegetables

为验证联普有机肥和土壤调理剂在蔬菜上的应用效果,以单施化肥和不施肥为对照,比较单施有机肥、单施土壤调理剂及两者配施对苋菜、辣椒、萝卜光合作用效率（以SPAD值衡量）、产量、维生素C及土壤肥力的影响。结果表明,单施有机肥处理蔬菜产量为单施化肥处理的96%～122%,且提高了蔬菜维生素C含量及土壤肥力;单施土壤调理剂处理蔬菜产量为单施化肥处理的92%～109%,维生素C含量高于有机肥处理;在所有处理中,有机肥与土壤调理剂配施处理蔬菜产量最高,且在辣椒中维生素C含量和SPAD值最高。综上所述,有机肥配合土壤调理剂在蔬菜上的应用效果最好,单施有机肥次之,单施土壤调理剂效果较差。

In order to verify the effects of organic fertilizer（OF） and soil conditioner（SC） on vegetables,the leaf photochemical efficiency（measured with SPAD value）,yield,vitamin C（VC） and soil fertility of edible amaranth,pepper and turnip were compared among the five treatments of no fertilizer control（CK）,chemical fertilizer（NPK）,OF,SC and OF combined with SC（OF＋SC）. The results showed that the yield of the three vegetables in OF treatment reached the 96%-122% of NPK,and the OF improved the VC and soil fertility in comparison with those of NPK. The vegetables yield in SC treatment reached the92%-109% of NPK,and the VC of edible amaranth and pepper were higher in the SC treatment than in the OF treatment.Regarding the OF＋SC treatment,the VC and SPAD of pepper and the yield of the three vegetables were highest among the five treatments. Therefore, the application of OF combined with SC showed the best effects on vegetables, followed by OF,and the effects of SC on vegetables were not good.
