Strange phenomenon of cotton: young peaches in the middle and upper parts crack ahead of time
Recently, some farmers called to reflect a strange phenomenon in cotton production: the lower big bolls and early cotton bolls grew normally and did not open bolls, while the tender bolls in the middle and upper parts cracked ahead of time, and some of them rotted bolls after cracking. Wuqiao County Agricultural Bureau immediately organized technicians to go deep into the field to find the reason. First, the field showed that the sowing was too early. In the early cotton fields where there were no buds or few buds in the upper 1 and 3 fruit branches due to Rain Water or diseases and insect pests, the number of cracking of cotton peaches in the middle and upper part was relatively large, that is, the outer bolls of 7 fruit branches and 10 fruit branches were counted from below.

Experiment, demonstration and Application of Industrial soilless Cotton Seedling in Dongtai area
Industrial soilless breeding of cotton is a seedling revolution in the history of cotton planting. It breaks the cultivation system of seedling cultivation and transplanting in nutrition bowl for decades, makes cotton seedling transplanting a simple, rapid, time-saving, labor-saving and cost-saving cultivation method, and opens up a new way for cotton cultivation. Experiment on soilless seedling transplanting introduced into Dongtai city in 2003. In 2004 and 2005, this technology was introduced into Tangyang and skimming port to carry out soilless seedling raising and large-scale transplanting experiment and demonstration.
