| 摘 要： | 通过田间小区试验,研究了鸡粪、猪粪和城市污泥不同用量对萝卜经济性状、产量和土壤肥力的影响.结果表明:在施用等量氮磷钾肥的情况下,施鸡粪的萝卜经济产量最高,较施化肥的增产39.8％,对氮磷钾养分的吸收量也最大,氮磷钾吸收量较单施化肥的分别提高32.5％、40.2％、48.5％.随着有机肥用量的增加,施鸡粪、猪粪的萝卜经济产量、氮磷钾吸收量呈先升高后降低的趋势,而污泥处理则随施肥量增大而增大.土壤中全氮、全磷、有机质、碱解氮、有效磷含量随施肥量增加而增加,而全钾和速效钾含量变化规律不明显.

| Abstract: | A field plot experiment was conducted to investigate the effects of different fertilizer rates of chicken manure,pig manure and municipal sewage on economic characters and yield of radish and soil fertility.The results showed that with the same fertilizer rate of N,P and K,the economic yield of radish was the largest in treatment applied with chicken manure,which increased by 39.8% than that in treatment applied with chemical fertilizers,while the uptakes of N,P and K were also the largest,which respectively increased by 32.5%,40.2% and 48.5% than that in treatment applied with chemical fertilizers.With increasing fertilizer rate of organic fertilizer,the economic yield and the uptakes of N,P and K in treatments applied with chicken manure and pig manure all showed a trend that increased at first,and then decreased,but those in treatment applied with municipal sewage showed a increasing trend.The contents of total N,total P,organic matter,alkali-hydrolyzable N and available P in soil increased with increasing fertilizer rate,but the change rules of total K and available K were not obvious. |
