利用1991－1995年地膜棉花分期播种试验资料，分别建立了籽棉产量和霜前花率积温模式，并建立了影响棉花品质的纤维长度、衣分、衣指及子指的温度、耗水量模型。分析了各自的影响机理，并推算了宁夏各地在气候正常年份下新陆早1号的产量及品质范围，发现宁夏存在棉花花铃期冷害，其出现概率为20％。
The temperature and water consumption models of fiber length, lint, finger and finger of cotton were established by using the data of seeding cotton mulching in 1991-1995. The influencing mechanism was analyzed, and the yield and quality range of Xinluzao No.1 under normal climatic conditions were calculated in all parts of Ningxia. The cold damage was found in Ningxia cotton at the flower-boll stage, and its probability of occurrence was 20%.
