主　　题：Precision seeding Laser land leveling Application effect Economic benefit 

摘      要：Rapid socio-economic changes in China,such as land conversion and urbanization,are creating new scopes for the application of precision agriculture(PA).An experiment to assess the economic benefits of two precision agriculture methods was applied for one year–precision seeding and precision seeding with land *** the results for this were positive,of itself it did not provide evidence of longer terms *** costs of land leveling are accrued in a single year but the benefits could carry over into subsequent ***,in this case if the PA method provides carry over benefits to future years,the economic assessment would incorrectly assign all the costs to a single year of benefits *** benefit-cost ratio would be *** gauge whether there was carry over benefits in future years we looked at NDVI and GUI as proxies for future year *** the single year experiment,our results showed that:(1)Winter wheat yield was increased 23.2%through the integration of precision seeding and laser leveling technologies.(2)Both the single technology and the integrated technologies significant reduced the concentration of soil ammonium nitrogen at the depths of 60 cm;(3)The benefit/cost ratio s of the treatments exceeded that of the baseline by approximately 10%which translated to an increase of several hundred US$per *** NDVI analysis showed that the effect of laser land leveling could last to the next two *** considering the multi-year impact of land leveling,the benefit/cost ratio of PSLL will increase to 23.5%and 22.9%with and without laser land leveling *** clear the eco-nomic benefits of using PA technologies will likely promote application of the technologies in the region.
