Urban Farm DB summary
A study on Beijing's urban agriculture cropping system, arguing that a rational choice of planting system is needed to overcome water resource constraints, realize agriculture's ecological service function of suppressing dust, and meet farmers' need for supplementary income, using a combination of literature research, experiments, and field surveys to examine the necessity of adjusting the planting system and the benefits of different systems. Comparing multiple benefits of a spring-maize single-cropping system against a winter-wheat/summer-maize double-cropping system, the spring-maize single-cropping system showed somewhat lower economic benefit than the double-cropping system, but better environmental benefit, lower water consumption, and greater potential for farmers' supplementary income. The study concludes that the spring-maize single-cropping system better matches the requirements of Beijing's urban agriculture development.
