摘要
3年定位稻麦连续施用鸡粪试验结果表明,稻麦连续每熟施用鸡粪9～27t / hm2,3年总产量增加8.7%～20.1%,但增产效果随连续施用时间的延长而呈下降趋势.连续施用量以每熟9～18t / hm2为宜,第3年后应为9t / hm2左右为宜.施用鸡粪可显著提高土壤养分,其增幅速效磷＞速效钾＞有机质和全N,增幅与鸡粪施用量成正比,改土培肥效果明显.
A fixed position experiment of continuous application of chicken manure on rice and wheat was carried out from 1998 to 2001. The results indicate that the total yield of rice and wheat applying chicken manure （9-27t/hm^2） to each crop continuously increases by 8.7% -20.1%. The growth rate is a downward trend as the time of continuous application is prolonged. The appropriate applying amount of the manure is 9- 18t/hm^2 each crop, and 9t/hm^2 is better from the third year. The soil nutrient raises notably by continuous applying chicken manure, and the range is available P〉 available K〉organic matter and total N,it is related to the amount of the manure.
