摘要
试验结果表明,优化鸡粪在等养分含量条件下,肥效与无机混合肥料基本相近,并稍有提高;在培肥地力方面,施用优化鸡粪可缩小种植蔬菜后土壤有机质下降的幅度。在相同条件和相同施肥处理情况下,新菜园土的增产潜力大于老菜园土;花椰菜的增产效应大于油菜。养分利用情况也与上述结果一致。优化鸡粪可用于配制蔬菜专用复合肥料,在蔬菜上值得推广。
In order to obtain some information of the effectiveness of the processed chicken manure on yield increments,soil fertility improvement and fertilizer efficiency,greenhouse experiment were carried out with cauliflower and rape, in comparision with mixed inorganic fertilizers of the same nutrients contents. The results showed that with the same nutrients amounts,the processed chicken manure had a better effect on crop yields than mixed inorganic ferti- lizers had.As for soil fertility,the application of the processed chicken manure could slow down the decomposition of soil organic matter in the planting period. The results also indicated that under the identical conditions and with the same fertilizer treatment,crops had a greater yield potential in the newly developed horticultural soil than in the well developed horticultural soil;meanwhile,in the same soil,cauliflower had a larger fertilizer response than rape.And so did nutrients utilization. The processed chicken manure can be used for manufacturing specialized compound fertilfzer.The common use of processed chicken manure in veg etab le production is worth recommending.
