我国现阶段适于纺高支纱的棉花品种资源除新疆的海岛棉外,陆地棉品种还基本上没有,纺高支纱的优质棉主要靠国外进口。济宁市任城区棉办高级农艺师张家友通过用陆地棉品种间杂交,对后代经过6a的定向选育,培育出了优质、高产的陆地长绒棉新品系15136和中长绒棉94-43B。为了探索这两个优质棉新品系的适宜密度、打顶时间和施肥量及产量水平,1999年济宁市棉办在济宁市农科所设置了这项试验。
At present, China’s cotton varieties suitable for spinning high yarn counties in addition to island cotton island in Xinjiang, there are basically no varieties of upland cotton, high-quality yarn count yarn mainly imported by foreign countries. Zhang Jiyou, a senior agronomist of any cotton area in Jining City, developed a high-quality and high-yielding new line of long-staple cotton land 15136 and long-staple cashmere 94-43B through the directional breeding of the offspring through 6a. In order to explore the appropriate density of these two high-quality new cotton lines, topping time and the amount of fertilizer and output levels, in 1999, Jining Cotton Office in Jining City Agricultural Science Institute set up this experiment.
