昌邑县大部分棉田为淋溶褐土,地下水源缺乏,土壤旱薄贫瘠,枯黄萎病混生。正常年份皮棉亩产50公斤上下。为寻求旱薄地条件下的双抗、优质、高产品种,于1984～1985年进行了旱薄地品种比较试验。结果表明,中棉12号平均比对照86—1增产16.8%,抗病性、丰产性、品质指标及子棉售价均居 Most cotton fields in Changyi County are leached cinnamon, lack of groundwater, dry and poor barren soil and yellow wilt. Normal year lint mu yield 50 kg up and down. In order to seek double resistant, high quality and high yield varieties under drought condition, comparative experiments were conducted between 1984 and 1985. The results showed that the average cotton yield of Zhongmian 12 was 16.8% higher than that of the control 86-1, and the disease resistance, high yield, quality index
