生物发酵残渣农业处理与利用研究

Disposal and Utilization of Fermentative Residue as Soil Amendment in Agriculture

通过田间小区实验,对生物发酵残渣农业处理和利用的效果进行了研究。通过两年对水稻、小麦、玉米、甜菜和苜蓿的实验证明,发酵残渣的施用可有效促进植物生长和提高作物产量。水田的施用效果要好于旱田,水田的最佳施用量为22.5 t.hm-2,旱田最佳施用量为11.25 t.hm-2。发酵残渣的施用可以降低旱田土壤pH值,提高旱田和水田的有机质含量。发酵残渣的农业利用是其处理的一条有效途径。

Effectiveness of agricultural disposal and utilization of fermentation residue was studied in a plot experiment. The result showed that application of fermentation residue in agricultural land as a soil amendment was likely to enhance both growth of plants and crop yields in the experiments with different crops of flee, wheat, corn, sugar beet and purple medic. Optimal loading rate for paddy field was 22.5 t · hm^ -2 and 11.25 t · hm^ -2for glebe, respectively. Application of fermentative residue may decrease pH value in glebe soil and increase the organic matter content in both glebe and paddy field soil. It is proved that agricultural utilization is an effect measure for the effective disposal of fermentative residue.
