对新开发园田用人粪土杂肥、沼气渣与化肥不同配比施用对土壤的培肥效果及蔬菜产量进行了初步探讨。经２－３年的试验结果表明：新开发园田在保证一定蔬菜产量的同时，又逐步提高土壤肥力，使土壤培肥与蔬菜增产同步进行，应采用有机、无机肥配合施用的措施。有机、无机肥比例应以４：６，５：５为好，无机肥要氮磷钾合理配比。有机无机肥配合施用使土壤物理性状有所改善，土壤养分、土壤酶活性有明显提高。
On the newly developed garden with manure mixed fertilizer, biogas residue and chemical fertilizer different proportion of soil fertility and vegetable yield were discussed. After 2-3 years of test results show that: the newly developed Gardena in ensuring a certain yield of vegetables at the same time, and gradually increase soil fertility, soil fertility and vegetable production simultaneously, organic and inorganic fertilizers should be used with the measures. Organic, inorganic fertilizer ratio should be 4: 6, 5: 5 as well, inorganic fertilizer to a reasonable ratio of nitrogen, phosphorus and potassium. Organic and inorganic fertilizers with the application of soil physical properties have improved, soil nutrients, soil enzyme activity was significantly improved.
