Let bonsai flowers bloom according to people's wishes.

Florescence control is to take artificial measures to make the bonsai bloom outside the natural flowering period and open regularly according to people's wishes. In order to meet the needs of festival exhibition or bonsai evaluation exhibition, delaying flowering has become an ideal means of cultivation.

(1) Light adjustment in order to make leaf flowers bloom on National Day, flower bud differentiation can only be carried out in a short-day environment, and the daily light time should be shortened to less than 10 hours 40-50 days in advance. Of course, for the leaf flower bonsai treated in this way, the vegetative growth must be perfect, the branch length is normal, and the axillary bud and terminal bud should be full and full. Small chrysanthemum bonsai, a short-day plant, can be treated with long sunshine in order to postpone its flowering period, starting from the beginning of September, stopping on October 10th and opening one after another in mid-December to supply New Year's Day market.

(2) Rhododendron and camellia are generally able to blossom ahead of time when they are cultured in a greenhouse before the temperature is adjusted into winter. When the room temperature increases to 20-25oC and the relative humidity reaches more than 80%, it takes 40-50 days for the cuckoo to bloom. Before the temperature warmed up in early spring, rhododendron and wisteria were given 1-4oC low temperature treatment in dormant spring, so that the dormancy period and flowering period were prolonged, and the flowering period could be delayed for more than 7 months.

(3) 4000mg/L gibberellin is effective in breaking dormancy of rhododendron and cherry blossoms. 500-1000mg./L dripped on the peony flower bud, began to germinate in 4-7 days, and dripped on the camellia flower bud twice a week. Half a month later, the flower bud differentiated rapidly and could blossom in the same year. Xiaoju was treated with 50mg/L naphthalene acetic acid in the middle of August, once every 3 days for a total of 50 days, and the flowering could be delayed for 10-14 days.

(4) cultivation and management measures to make bonsai blossom continuously through pruning. The flower branches are cut short immediately after the rose flowers are shedded, which can make them produce new flower branches and blossom continuously. Crape myrtle will be cut off immediately after blooming in summer to prevent it from bearing fruit, while strengthening fertilizer and water management, it can blossom for the second time in autumn. When the leaves were removed from September 8-10, the florescence was advanced to late September to early October. Artificially control water, make plant leaves dormant, and then give water supply at an appropriate time, it can release dormancy, germination, growth, flowering, cloves, plum blossoms and other bonsai can blossom in "National Day" with this method.
