巢湖地区稻虾共作模式对稻田土壤肥力的影响
Effects of the integrated rice-crayfish mode on soil fertility in Chaohu Lake region
摘要
Abstract
Two sampling areas around Chaohu Lake were set up to monitor the variation of soil fertility in 2016.We collected soil samples before rice plantation,vegetative growth stage and after harvest,respectively.Total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus,available potassium,and cation exchange capacity were analyzed.The rice yield was evaluated.The results showed that the rice yield was 2％-3％ higher in the integrated rice-crayfish mode than in the monoculture rice mode.The yield of crayfish was above 1 200 kg·hm-2 under the regular feeding.The soil fertility was better in the integrated rice-crayfish mode in sampling area A (P ＜0.05) than the monoculture rice mode.The organic matter,total phosphorus,and cation exchange capacity were higher than those in the integrated rice-crayfish mode in sampling area B with no significant difference in other fertility factors (P＞0.05).In general,the integrated rice-crayfish mode was more conducive to maintaining soil fertility.关键词
