| Through different part nodes, different sample length, different cutting depths and different rooting agent test, we investigated the influence of some factors in the survival of cotton cuttings and cuttings on the growth and yield. The conclusions are listed as follow:1,Different length nodes cuttings can survive. Specially 5cm～8cm long cutting, the high of new post-stem and the number of new leaves were better than other node cutting length.2,The effection of chemical reagent on survival rate of cotton node cuttings was limit. The survival rate were 100% treated by rooting agent, thiophanate methyl, carbendazim, while the rate was 97%. However, these pharmaceutical treatments had affected the seedling root number, root weight. Experiments showed that carbendazim had the best influence in node rooting, and there were significant effects caused by rooting agent. But the impact of thiophanate-methyl treatment was not better than that of water control.3,Although all node cuttings of Cotton stem, monopodium and fruit branch could survival, there were highly significant result of root number, surface area and the length of seedlings in monopodium cuttings, the worst is stem cuttings. In contrast, the thickest cuttings root diameter was the stem node cutting.4,Through analysising different parts node cuttings in field, there were directly impact of parent plants in node cutting seedling from agronomic and ecomomic traits; there were not obvious effects of different parts of parent plants on cutting high and boll number, but significant impact in the number of fruit branches and fruit sites.5,Through comparing the biological and economic yield after cutting seedling transplanted into field, cotton node cuttages is practical valuable.
