In order to explore the law of cotton high yield formation and cultivation techniques, the authors conducted high-yielding cultivation experiments and large-area production surveys since 1974. Based on these trials and survey data, this paper discusses several issues in high-yielding cotton cultivation as follows. First, the impact of climatic conditions My county is located in the Jianghai plain cotton and wheat intercropping area, perennial frost-free period of 210 to 220 days.
