Abstract:

Five kinds of growth regulative substance and trace element, which bamboo needs for growth, have been selected and used in experiment and practice, according to five element rotation quadratic orthogonal design method, Based on the experimental data, an optimum combining scheme has been formed by computer simulating and optimizing. After application, the output of bamboo shoot and standing shoot can increase 80 to 100 percent, the shoot emergence time is earlier 7 to 10 days, and the degraded shoot period will prolonged for 15 to 20 days.
