In order to make the oak leaf hydrangea uniform when it blooms, the size of the plant needs to be screened during the cultivation process, so as to meet the requirements of production standardization; also in order to ensure the test results in the test It is not affected by the size of the plants, and it is required to choose plants of uniform specifications when planting. Therefore, in this planting process, all biennial plants with 10-12 branches, branch length not exceeding 30cm, and cutting origin plants were selected. Choose a flower pot with a pot diameter about 10 times the root diameter of the plant. The cultivation medium should be loose and breathable, well drained, and have high fertilizer content.

Abstract

The invention discloses a hydrangea quercifolia flowering adjustment method. The method includes following steps: (1), selecting plants: selecting plants of two years old, with 10-12 branches not exceeding 30cm in length and originating from cuttage; (2), planting the plants in a pot; (3), shading: selecting a black or silver-gray shading net of 50-80% in shading rate to shade the plants after a plant bud emerging period. By shading hydrangea quercifolia, white flowers can be changed into viridescent flowers, so that the problem that hydrangea quercifolia is unitary in flower color is solved.In addition, the flowering period of hydrangea quercifolia is adjusted by two ways of snow melting and pinching to adjust market supply time of hydrangea quercifolia, and needs of people on viewing hydrangea quercifolia at different times are met; flowering period adjusting cost can be greatly lowered by utilizing snow melting to postpone the flowering period.
