| Abstract: |
| For further improving the operation performance of soil mulching on plastic-film and dibble machine for dry-land wheat, taking advance velocity of the machine, linear velocity of scraper soil elevating and dip angle of scraper soil elevating as for the independent variables, the percent pass of average soil mulching as for response, according to the testing design principle of the Box-Behnken, using the analysis method of three factors and three levels, set up the mathematical model for each experiment factor with the mean percent pass of soil mulching, and carried out the analysis for each factor and interaction function. The test results showed that: The decreasing sequence of three parameters to influence the average percent pass of soil mulching were the advance velocity of machine, dip angle of scraper soil elevating and linear velocity of scraper soil elevating mechanism. The optimal working parameters of the machine were: the advance speed 0.55 m·s-1, linear velocity of scraper soil elevating 1.00 m·s-1 and dip angle of scraper soil elevating 40°. The results of confirmatory tests showed that : The average percent pass of soil mulching was 98.6%, the operation performence of soil mulching was significantly improved compared with before the optimization. |
