Abstract：In order to screen out the varieties of non-heading Chinese cabbage suitable for mechanized cultivation in the middle and lower reaches of the Yangtze River,13 varieties were cultivated with Xiafei 599 as the control.The variety Jinpinxiaguan was selected for its upright plant architecture,highest yield,lowest nitrite content,and suitability for me-chanical harvesting.To explore the mechanization characteristics of Jinpinxiaguan,the yield,harvesting efficiency,and economic benefit were conducted under different sowing dates and densities.The experimental included four densities:1560 plants·667 m-2(D1),1280 plants·667 m2(D2),1000 plants·667 m-2(D3),720 plants·667 m-2(D4),and three sowing dates:April 3rd,2023(M1),August 13th,2023(M2)and November 6th,2023(M3).The results showed that under the same sowing density,the M2 had the characteristics of low leakage loss rate,high integrity rate and low impurity rate,and the yield,output value and economic benefit were the higher than that of,M1 and M3.Under the same sowing date,with the increase of the sowing density,the leakage loss rate,damage rate,impurity rate decreased,while the integrity rate,yield,output value increased.The economic benefit of Jinpinxiaguan sown in M2 increased with the increase of sow-ing density,and the benefit of D1 reached 6 255.62 yuan·667 m-2.For the M1 and M3 sowing dates,although higher seed amount increased the yield and output value,the associated seed cost also rose,with economic benefit peaking at the D2 sowing density.The feasible combination recommend is M2+D1,M1+D2 or M3+D2.
