Abstract: Three kinds of direct seeding planting methods commonly used by cotton farmers（code A： trench strip sowing, code B： bamboo tube on-demand, code E： trench on demand） and two new kinds of cotton board direct seeding planting methods （code C： burrowing sowing with covering fertilizer, code D： burrowing sowing with covering soil） in northern Jiangxi province were used planting cotton. The using time, labor intensity, amount of seeds weight, emergence rate and agronomic traits of cotton under different direct seeding mode was compared to find a suitable way for direct seeding planting to reduce the labor intensity of cotton farmers, reduce the labor input and increase the benefit of cotton planting in northern Jiangxi. The results showed that five different direct seeding planting methods had no significant effect on the agronomic characters and fiber quality of cotton, and the emergence rate of each direct seeding method was better, above 85% （except A）. The performance of mode A was less saving time and not saving effort, which was greatly affected by cotton field moisture. The performance of mode B was saving time and effort, but it had strict requirements for cotton field moisture, which was used according to soil moisture. The comprehensive performance of mode C was better, which was saving time and less saving effort. The performance of mode D was less saving time and not saving effort, which had strict requirements for cotton field moisture. The performance of mode E was saving time and not saving effort, which was greatly affected by cotton field moisture. Comprehensive analysis, burrowing sowing with covering fertilizer （code C） and bamboo tube on-demand （code B） had good comprehensive performance. They achieve the purpose of light simplification of planting, which are suitable for large area planting and further demonstrated and popularized in cotton-planting area of northern Jiangxi.
