几种有机肥在有机桃树（拂晓）上的应用效果

摘要

根据镇江地区桃园土壤肥力偏低的情况，针对有机桃园散养草鸡，鸡粪还田的农牧结合复合经营模式对桃园土壤及桃树生产的影响效果研究甚少的状况，开展鸡粪还田对土壤肥力状况及桃树的影响研究。试验结果表明：鸡粪对土壤养分的影响比商品有机肥略差，但是，鸡粪能很好的促进桃树生长，增强树势，提高桃树果实产量；而另一方面，施用自产鸡粪桃树果实个小，商品性差，病果率高达31.2%，而且不耐储藏；桃园散养草鸡或鹅，禽粪还田的生态农牧结合复合经营模式需要加强防疫，方可取代施用商品有机肥料。%The research explored the effects of compound management model on soil fertility and peach tree production, involving free-range chicken and returning chicken manure to fields. The results showed that the effects of chicken manure on soil fertility were poorer compared with organic fertilizers, but the former would bet-ter promote peach tree growth and improve yields. On the other hand, the peach fruits applied with chicken manures were smal in size and poor in commercial val-ue. What’s worse, disease rate reached 31.2% and the fruits could not be stored for a long term. Therefore, the compound management model combining agriculture and animal husbandry should intensify epidemic prevention to take place of organic fertilizers.
