不同密度、肥料水平对苏抗 1 0 3产量影响的试验结果表明 ,不同生态区域以中密、中肥处理产量水平最高 ,在江苏沿江棉区的种植密度为 4 2万株·hm- 2 ,施纯氮 2 70Kg·hm- 2 ,可获得 1 4 0 6Kg·hm- 2 的皮棉产量。在江苏里下河棉区种植 ,可获得1 983Kg·hm- 2 的皮棉产量。
The results of different densities and fertilizer levels on the yield of Su-resistant 103 showed that the yield levels of middle-dense and medium-fat treatments were the highest in different ecological regions, and the planting density was 42,000 ha-2 in the cotton fields along the Yangtze River in Jiangsu Province. Application of pure nitrogen 2 70Kg · hm-2, can get l046Kg · hm-2 lint yield. In Lixiahe cotton plantation in Jiangsu Province, lint yield of 1 983Kg · hm-2 was obtained.
