摘要
在潮土上施用垃圾肥对花生产量和品质影响的研究结果表明，在较贫瘠的土壤上，垃圾肥单独或与Ｎ、Ｐ化肥配合施用，都有明显的增产效果：单独施用比对照增产率为９．３％～２９．１％，与化肥配合施用增产率为１０．８％～２０．５％。垃圾肥施用量在１５～３０ｔ／ｈｍ２时可获较高的增产效益。施用垃圾肥对花生仁中的粗蛋白质、粗脂肪和全磷含量有一定的提高。尽管所施用垃圾肥中含有一定量的有害元素，如Ｃｄ、Ｐｂ、Ｃｒ等，但花生仁中这些元素含量并不高，说明施垃圾肥是安全的。试验结果还表明；施用垃圾肥能提高土壤有机质、全氮以及有效Ｎ、Ｐ、Ｋ的含量。特别是有效微量元素含量提高幅度较大，Ｚｎ、Ｃｕ、Ｂ各处理平均是对照的２～１０倍，Ｆｅ、Ｍｎ、Ｍｏ比对照提高１７％～３８％。
A field experiment was conducted to study the effect of compost applied to calcareous meadow soil on the production and quality of peanut. The result showed that compost application could increase the yield of peanut by 9. 3%～29. 1 % ,and mixed application of compost and chemical fertilizers increase the yield by 10. 8%～20. 5%. The suitable application rate of the compost is 15～30 t/hm2. Although the contents of some heavy metals are hight in the compost,they are found very low in shelled peanut. The result also indicated that compost application led to increase both available macronutrients and available micronutrients in the soil.
