Mechanical-chemical synergy has been proven efficient in weed control. However, characterizing the state of weed–soil complex after mechanical weeding and revealing its effects on subsequent herbicide application is still challenging, which restricts implementation this technology. This paper first presents a method to characterize from perspectives fragmentation composite characteristics. The ...

Manual, semi-conventional, and conventional weed eradication are the three forms of utilized. Farmers benefit greatly from usage weeding equipment in combating pests fields. The blade you use determines how successful at weeding. As a result, it is required to examine weeds blade. With tetrahedral mesh, simulation utilizing finite element analysis approach allows for optimization design, comput...

Current approaches to topdressing and weeding operations for rice cultivation present several disadvantages, such as poor precision, low efficiency, serious environmental pollution, so on. This paper presents a row-controlled fertilizing–weeding machine improve the precision of fertilizing reduce heavy pollution associated with cultivation. A proportional–integral–derivative algorithm was adopt...
