摘要:
为了明确稻-菌-鱼复合生态系统对水稻产量和经济效益的影响程度，采用畦作和平作两种水稻栽培方式，测定并分析了两种栽培方式下土壤温度和土壤中速效养分含量及其关联性，同时对复合生态系统下综合经济效益进行了分析。结果表明：复合生态系统下垄畦式立体栽培有效提高了土壤的吸热性和导热率，使土层温度有明显的提高，充分改善了稻田生态环境；土壤速效养分的感温效应表现为土层温度每提升1℃，土壤碱解氮含量增加4.0 mg.kg-1,土壤速效磷增加0.3 mg.kg-1,速效钾增加1.3 mg.kg-1，土壤温度与速效养分含量之间呈线性关系，相关系数达到显著水平；垄畦作26、20和10 cm分别比平作30 cm×26 cm、30 cm×20 cm及30 cm×10 cm增产28.13%、68.49%和67.40%，且垄畦式立体开发投入产出比比平作多13.47。
Abstract:
In order to define the effect degree of compound ecosystem of the rice-edible fungi-fish on the rice yield and economic benefit,adopting ridge culture and flatten culture as rice cultivation mode,soil temperature and soil available nutrient content and its relevance of different cultivation modes were analyzed,the integrated economic benefit of the complex ecological system was studied.The results showed that the ridge culture stereoscopic cultivation effectively improved heat absorptivity and thermal conductivity of soil,temperature and ecological environment;thermal effect of soil available nutrient was when the soil temperature was increased 1℃,soil alkali-hydrolysable nitrogen content was increased 4 mg?kg-1,soil available phosphorus was increased 0.3 mg?kg-1,rapidly-available potassium was increased 1.3 mg?kg-1;there was a linear relationship between available nutrient content and soil temperature,the correlation coefficient reached significant level;ridge culture for 26,20 and 10 cm compared with the flatten culture for 30 cm×26 cm,30 cm×20 cm and 30 cm×10 cm was increased 28.13%,68.49% and 67.40%,respectively the rates of input and output of ridge culture stereoscopic development were more than flatten culture 13.47.
