Abstract:To beter clarify the matching and economy of mechanized technology and equipment for soybean-maize strip intercropping,andtoguide thepoor sowingqualitycausedbytheinsuficient plant spacingadjustmentandunmatched sowing parameters encountered inthe production processIn thispaper,byanalyzing thesituationof soybean production andconsumptionin Chinaand soybean-maize strip intercropping in Jiangsu Province,itis evidentthat achieving complete self-sufficiency in soybean production would require expanding the planting area by 81.2% .Increasing soybean planting areaand enhancing yield areviableapproaches toalleviatethe suply-demand imbalance.Over yearsof development,the 4+2 soybean-maize strip intercropping model as the primary promotion framework in Jiangsu Province,while scientifically incorporatingotherstripintercroppingmodels.Thetechnicalpathwayforsoybean-maizestripintereropping hasben proposed,covering aspects such as varietyselection,pre-crop treatment,seed procesing,selection of sowing machinery, densityconfiguration for several major intercropping models,and sowing operational requirements.Aditionally,the supporting technical and equipment requirements for mechanized sowing havebeen specified.Theeconomic analysis of soybean-maize strip intercropping under 4+2 mode was carried out,and the corresponding relationship between planting density and row spacing and plant spacing under the three main modes of 4+2,4+4 and 6+4 was established. The results of economic analysis showed that the 4+2 model of soybean-maize strip intercropping increased the income of 3 538.5 yuan/ hm2 compared with pure maize. After considering the subsidy benefit,the eficiency of composite planting was 8 338.5 yuan/ hm2 compared with pure maize.
