| Abstract: | In order to explore a high-yield cultivation technique for a cotton variety Shenggongmian 2, its optimal planting density and fertilizer application rate were studied in this experiment by a randomized block design. The results show that the optimal planting density for Shenggongmian 2 was 52 500 plants / hm^2, under which the optimal fertilizer application rate for it was 900 kg / hm^2 of Sierte cotton special low-release fertilizer and its seed cotton yield could reach 3 422.5 kg/hm^2. |
