Abstract: The climatic resources such as temperature and rainfall during the growth period of early-maturing cotton in Huanggang City, Hubei Province, from 1990 to 2019 were analyzed in order to reveal the changes of climatic resources during the growth period of early-maturing cotton in this area, and to provide a scientific basis for the breeding and management techniques of early-maturing cotton in Huanggang City, so as to lay a foundation for the promotion of early-maturing cotton in Huanggang City. The results showed that from 1990 to 2019, in the sowing-emergence stage of early maturing cotton, the rainfall was moderate and the probability of rainfall was high, which was suitable for entropy-controlled machine sowing and conducive to achieving full seedling emergence at one sowing. The temperature in the emergence-flowering and flowering-boll opening stages was higher than that of the sowing-emergence stage and boll opening-harvest stage, and the rainfall was more, but with the passage of time, the rainfall in the two stages showed a decreasing trend. From the boll opening stage to the stop growth stage, the rainfall was less and the rainfall probability was low. Based on the climatic characteristics of Huanggang City, it was suggested that early-maturing cotton varieties with high temperature resistance and high density resistance should be selected in Huanggang City. The sowing time should not be later than June 5, and the integration of agricultural machinery and agronomy should be emphasized.
