Research and Development of 2 BMYF-4 Intelligent No-till Maize Planter and its Field Experiment
摘要
Abstract
Based on the agronomic characteristics with yearly maize-wheat rotation and large amount of straw cover after wheat harvesting and blocking during no-till maizeplanting in Shandong Province , a new-concept no-till wheat-maize planter , named 2 BMYF-4 intelligent no-till maize planter , has been researched and developed by researchers from Shandong University of Technology to solve some extremely important problems , such as chopping and covering standing wheat stubble in one-stop operation in double cropping areas of Shandong Province in China .The combined anti-bloc-king device composed of powered chopping axle and the planting unit with chisel opener was designed .The planting spacing regulation transmission was used to meet the needs of different planting densities .In order to meet the require-ments of automatic monitoring of farming quality and quantity of large scale precision seeders , an intelligent system with video monitor function for gauging and monitoring seed and fertilizer was researched and developed .Field performance test results at Zhangqiu , Zhangdian and Zhoucun showed that this planter could accomplish many procedures , such as stubble chopping , furrow opening , seed and fertilizer placement , suppressing , etc, in one-stop operation , thus the oper-ation cost could be reduced by about 30%.The machine worked very well for planting maize while shattering standing wheat stubble .The powered chopping axle resolved the anti-blockage problem ahead of shank , and the double-chisel o-pener unit reduced the blockage between planting units , thus the cross-country ability of the planter was improved . Meanwhile, the coefficients of variation(CV) for fertilizer and seed depth were reduced to 17.2%and 18.6%, respec-tively.The free-swinging knife of the planter can cut straw stubble in shallow soil with less than 20% soil breakage , which can prevent soil degradation .Therefore , this machine will be a good solution to no-till wheat-maize planting in double cropping areas .关键词
