Abstract：Complicate effects of the silicate bacteria and fertilizers on cotton were studied. The results showed that the bacteria could obviously promote the absorption of nutrients and the increment of branch leaves，boll number and lint yield. It had better effects when applied with N，P and K chemical fertilizers. The branch leaves，boll number and lint yield of cotton were 12%，16.5% and 30% higher，the accumulation of N，P and K were 19.1%，19.5% and 23.7% higher than those of the control plots respectively. And it obviously encourages the cotton plant growth and development.
