自21世纪初高密度植棉模式在全疆推广以来,尽管出现了不少局部高产、超高产棉田,由于仍采用常规密度植棉模式下的化学调控与头水晚、二水赶、三水适时灌的统一措施,棉花盛蕾期起田间长势开始出现分化,最终呈现了中产、中低产棉田比例大与高产、超高产田比例小的状况。为了摸清
Since the beginning of the 21st century, high-density cotton planting mode has been popularized in Xinjiang, although some local high-yielding and ultra-high yielding cotton fields have emerged, due to the chemical regulation under conventional density cotton planting mode, Timely irrigation of uniform measures, the growing stage of cotton began to appear fragmentation, and eventually showed the middle and low yielding cotton fields with a large proportion of high-yielding, ultra-high yields of small proportion of the situation. In order to find out
