2BF-5型玉米-大豆带状间作精量播种机设计与试验
Design and experiment of a type of 2BF - 5 maize-soybean strip intercropping precision seeder
摘要
Abstract
Based on the advantages of whole machine drive and simulated seeding monomer,a new type of 2BF - 5 maize-soybean strip intercropping precision seeder was designed to solve the problems of not working well and low comprehensive benefits of traditional maize-soybean intercropping seeder. Meanwhile,the spacing qualified coefficient,leak index,repeat sowing index,emergence rate and yield were selected as the evaluation indicators for single factor randomized block design to test the working performance of the seeder and to study the effect of mechanical seeding on crop emergence quality under three different farming methods,stubble with no-tillage,cleaning stubble with no-tillage and cleaning stubble with rotary tillage. The results showed that the spacing qualified coefficient fluctuated within the range from 75. 8 to 83. 57％ under different conditions,while the leak index and spacing variable coefficient fluctuated within the ranges from 7. 8％ to 9. 17％ and 11. 4％ to 15. 4％,respectively. And all the performances comply with relevant standards and actual production requirements. Analysis of emergence rate and yield indicates that the treatment of CSNT got the highest yield compared with the other two experimental groups.关键词
