A comparative study of energy flow and eronomic flow for the strawberry production system between management in organic and inorganic ways

On the basis of the principle of ecological eco-nomicx,comparative study of energy flow and nitrogen con-version for the strawberry preduction system between man-agement in organic and inorganic ways was studied. The re-sults showed that although almost same amount of N applied in organic(175kg/hm²)and inorganic(164kg/hm²)treatment,the growth,development and yield of the strawberry in organic treatment was better than that in inorganic treatment during strawberry growth period,The utilization rate of solar energy and output/input ratio of nitrogen in organic treatment were 64.24%and 57.72%higher than those in inorganic treatment respectively. The result also proved biogas slurry is a good or-ganic manure and can improve the fruit quality of strawberry and bring sound economic benefit.
