长期施用鸡粪稻田土壤肥力变化特征研究
Changes in Fertility of Paddy Soils under Long-term Chicken Manure Application
摘要
Abstract
The changes in the main fertility indexes of paddy soils after long - time application of chicken manure and chemical fertilizer were comparatively analyzed through sampling investigation in Hai' an county, Jiangsu province. The results showed that: as compared with the long - term application of chemical fertilizer, the long - term application of chicken manure could obviously improve soil physical properties, significantly enhance the contents of organic matter, total nitrogen, available nitrogen, total phosphorus, a-vailable phosphorus and available potassium in the soil, and had the greatest influence on the soil available phosphorus content. The long - term application of chicken manure also caused the accumulation and transfer of N and P into the underlayer soil, and made the soil nutrient content below the cultivated layer markedly higher than that in the soil applied by chemical fertilizer.关键词
