城市垃圾堆肥制备专用肥对蔬菜生产和环境的效应

通过小区和大田试验方法，研究了城市生活垃圾肥制备有机。无机复合专用肥对蔬菜和土壤环境的效应。结果表明，施用该专用肥的辣椒、蕃茄或茄子、莴笋和青莱的小区和大田的产量，与对照相比分别增加２７．０％－８８．８％和２０．７％－９５．４％，其增产在Ｐ０．０１水平上达到显著，且蔬菜中一些营养成分的含量增加．而重金属Ｃｄ、Ｃｒ、Ｐｂ、Ａｓ元素的含量均未超有关卫生标准。长期施用，可补充土壤中有机质，且肥料中重金属元素不会引起菜地环境的污染。

EFFECT OF OBLIGATE FERTILIZER PREPARED WITH GARBAGE COMPOST ON VEGETABLE PRODUCTION AND ENVIRONMENT

The effect of organic and inorganic compound obligate fertilizer on vegetable production and soil environment was studied through plot and field experiments. The results indicated that the yieds of hot pepper,tomato or eggplant, lettuce and green vegetable(Brassca campestris L.ssp.chinensis(L.)Makno var. commumis Tsen et. Lee)applied with the obligate fertilizer were increased by 27.0%-88. 8% and 20. 7%-95.4% respectively compared with the control,and the increase was very conspicuous (P<0.001). Some nutrients were also increased in the vesetables, but the contents of heavy metal elements,such as Cd,Cr, Pb,Cu and As were still below the health standards. Long term application of the fertilizer will supplement the soil with organic matter and the heavy metals in the fertilizer wil not pollute the soil environment.
