In May-June this year, some cotton areas in Xinjiang suffered extreme weather such as hail, heavy rainfall, and continuous high temperatures in July. According to the "2015 National Cotton Growth Survey Report (June)" (hereinafter referred to as the "growth report") released by the National Cotton Market Monitoring System, "76.1% of farmers in the northwest inland cotton area reflected that the weather was good and average; 8.9% of farmers reflected that the disaster occurred moderately or heavily ", which is consistent with the actual situation.

At present, the cotton in Xinjiang is growing well, comparable to previous years, cotton plant height in 70-90cm, 6-9 fruit branches / plant, buds 9-13 / plant, flowering 3-5 / plant, the bottom of the boll 3-4 / plant. Cotton is in the critical boll stage, but also the high incidence of cotton bollworm, aphid and red spider. According to the growth report, "98.9% of farmers in the northwest inland cotton area reflected mild occurrence of diseases".

The growth report noted that "the average yield in the northwest inland cotton region increased by 8.5% over the previous year, and yield decreased by 1.7%." Why after the reduction in yields increased? According to the autonomous region's Department of Agriculture, deputy director of the planting industry Zhong Yanlong, the reduction is to ensure that the cotton planting area on the basis of a certain scale, through the adjustment of the planting structure, making cotton planting to the high-yielding cotton area concentration.

July-August is a key period of cotton yield and quality formation, weather changes will have an important impact on cotton growth, China Cotton Network will continue to report, please pay attention.
