A PRELIMINARY REPORT ON TECHNOLOGY IN TRANSFORMING BAMBOO GROVE FROM “OFF” YEAR TO “ON” YEAR

This report indicated that the economic yield and biomass of bamboo grove in mixture year were higher than those in "on" year and "off year in the same location. In addition, steady bamboo products could be provided year by year in bamboo grove in mixture year. According to the data of the experiments of two generations which included four treatments used for transforming bamboo grove from "on" year and "off" year to mixture year, it was showed that there was the best effect of strong shoot thinning during the on-year spring on inducement of the number of bamboo in off-year and promoting the speed of transforming bamboo grove. Also, it was much better than the other three treatments which included isolating rhizomes to bamboo individuals, changing cutting period and naturally remaining shoots during "off year and there was no significant difference among the three treatments.
