禽粪有机肥对土壤主要养分和微量元素锌累积的影响
Effects of Poultry Manures on the Main Soil Nutrients and Zinc Accumulation
摘要
Abstract
Aimed at resolving the unreasonable disposition and disadvantage to environment of poultry ma nures , The research on the effect of different rate of organic chicken manure and duck manure on the main soil nu trients and trace element zinc accumulation were carried out by a field plot experiment. The results showed that the soil organic matter,total nitrogen,total phosphorus and total Zn contents increased significantly with the increasing rates of the organic manure,respectively. The soil available nutrients nitrogen, phosphorus and Zn supply could be maintained by the combined application of the low chicken,duck manure rate(15 t/ha) and chemical fertilizer in the wheat season. The contents of soil nitrate, available phosphorus, available Zn increased significantly when the rate of chicken and duck manure were 90 t/ha and 150 t/ha, respectively. The major soil nutrients and trace ele ments zinc could be accumulated by application of the excessive poultry manure. With the increasing amounts of the organic manure,wheat yield increased significantly. Appropriate application rate of organic manure was 60 -90 t/ha.关键词
