摘　　要：为了探索省工棉2号的高产栽培技术,采用随机区组设计,对其最佳种植密度和最适施肥量进行了研究。结果表明,在桃园县地区,省工棉2号的最佳种植密度为5.25万株/hm2,在该种植密度下,司尔特棉花专用缓释肥的最佳施用量为900kg/hm2,籽棉产量可达3422.5kg/hm2。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.
