| 摘 要： | [目的]探索常熟枣园林下养鸡对土壤物理性质的影响。[方法]在枣园林下设置5个处理,即放养鸡密度依次为0只/hm2(CK)、1 200、1 800、2 400和3 000只/hm2,研究了枣园林下养鸡对0~20 cm土层土壤p H、自然含水量、容重、总孔隙度、有效孔隙度和非有效孔隙度的影响。[结果]放养区各处理的土壤p H、自然含水量、总孔隙度、有效孔隙度和非有效孔隙度均低于未放养区;放养区土壤容重大于未放养区。[结论]长期林下养鸡会破坏土壤物理性质,应控制放养密度和放养时间,以1 800~2 400只/hm2为宜。

Effect of Raising Chicken on Soil Physical Properties in Jujube Orchard |
| |
| Abstract: | Objective] The aim was to explore effects of raising chicken on soil physical properties in Changshu jujube orchard.[Method] Set-ting up 5 treatments in jujube orchard, namely 0 (non-chicken raise plot), 1 200, 1 800, 2 400 and 3 000 ind/hm2 , effects of raising chicken on 0-20 cm soil pH, natural moisture content, bulk density, total porosity, effective porosity and non effective porosity were studied.[Result] The results showed that the pH, soil water, total porosity, the ratio of effective porosity and non-effective porosity of the soil in CRP decreased obviously than NCRP, the bulk density of the soil in CRP increased obviously than NCRP.[Conclusion] Long-term raising chickens under or-chard can destroy soil physical properties, the density of chicken and the duration should be controlled as 1 800-2 400 ind/hm2 . |
