The Technology to Promote the Decay of Bamboo Stumps

The decay of bamboo stumps is extremely slow in the natural state,to accelerate the decomposition,We add the potassium hydroxide as decay promoting agent inside of the bamboo stump. The results showed that after the treatment in the bamboo stumps violent reaction occurred in the first half of the month. The best effects were achieved at treatment B when potassium hydroxide dosage was 50g per stump,In the bamboo stumps the solution pH quickly dropped from 13 to 8. 5 within half a month,then slowly declined,alkaline disappeared entirely in 2 months,then stabilized at about 6. Compared with the control,the degradation of bamboo stumps by has been significantly accelerated by potassium hydroxide, and the degradation rate is faster at early stage than later stage,and the decomposition rate of bamboo stump under treatment B is higher than that under treatment A and C,the bamboo stump pieces in the decomposition bag under treatment B were almost completely decomposed in six months.As time changes,the potassium concentration in the solution of bamboo stumps gradually reduced,while that of bamboo leaves increased gradually,indicating potassium hydroxide can also act as fertilizer of bamboo growth,besides as decay promoting agent. In comparison with manpower digging,using potassium hydroxide as decay promoting agent can save the cost 1. 225 Yuan / stump. In addition,it is also of ecological significance. Therefore,as decay promoting agent of bamboo stumps,potassium hydroxide is expected to be applied in the practice of bamboo forests.
