Preliminary Research on intensive planting techniques of Dendrocalamus brandisii (Munro) Kurz to obtain bamboo shoots in Cau Hai, Phu Tho province
Keywords:
Dendrocalamus brandisii,, bamboo shoot,, intensive planting techniques,, Phu ThoAbstract
Research and identification of intensive planting techniques are capable of
increasing productivity, economic efficiency for bamboo species
supporting bamboo shoot, especially Dendrocalamus brandisii, an
indigenous bamboo species, is really necessary. The study has implemented
experimental formulas of fertilizer amount, amount of water for irrigation,
number of mother culm retained, time of retaining bamboo shoot to become
mother culm next year. The experiment results showed that. The amount of
fertilizer and irrigation water had a significant effect on the quantity,
diameter and bamboo shoot yield of D. brandisii and the formula N4P4 is
best. It is best to retain bamboo shoot to become mother trees in June - July
and bequeath 5 mother trees 1 year old and 5 mother trees 2 years old per
clump produce the best number and yield of bamboo shoots
