The invention discloses a cultivation method for controlling tips and promoting flower
bud differentiation of
syzygium samarangense, and belongs to the technical field of tip control cultivation of
syzygium samarangense. The method comprises the following steps: slightly shearing 70-80 days before flower forcing in the
wax apple production period, applying a
phosphorus-
potassium-
silicon mixed
fertilizer in holes on the ground, and applying the
fertilizer once every 15 days, totally twice; then a mixed
aqueous solution of
potassium phosphite and
paclobutrazol is sprayed to leaf surfaces and drips water, spraying is conducted once every 15 days, and spraying is conducted 2-3 times in total; after spraying is conducted for 5-7 days, closed
girdling is conducted, after 40-45 days, a mixed
aqueous solution of
auxin and a
plant nutrition regulator is used for spraying, spraying is conducted once every 15 days, and spraying is conducted 1-2 times in total. The
silicon fertilizer is mixed and added in the fertilizer and water management period to assist in increasing the absorption and
utilization rate of the
phosphorus-
potassium fertilizer; besides, through the synergistic effect of tip control,
trunk girdling and a mixed
aqueous solution of
auxin and a
plant nutrition regulator,
syzygium samarangense plants are stable, flower
bud differentiation is promoted, meanwhile, the method has the characteristics of
disease resistance,
disease prevention, high flower forcing and flowering rate and large
inflorescence amount, and the important effects of annual flowering and fruiting and promotion of syzygium samarangense industry
synergy can be achieved; the method has the advantages of simple operation process, high efficiency, stability, few use times and labor cost saving.
