Abstract: The aims were to explore feasibility of increasing cotton yield and new mechanized harvesting ways, and open up new ways to achieve production increase and mechanization. Based on previous researches, the author conducted tests on the delaying of boll opening. The results showed that the dry matter weight of boll was the maximum at 50- 55 days, and late stage boll opening reduced dry matter weight because of consumption, growth regulator could be used to delay boll opening, the boll open could be delayed for 5-10 days. The theoretical foundation and basis of production increase was elucidated by the test result. It is concluded that this harvesting way could improve yield by delaying boll opening, and provide reference for achieving mechanization in the whole cotton picking process.
