Embodiment 1

[0015] This embodiment is to test the "Purple Hydrangea" chrysanthemum variety. The specific adjustment method is: cutting seedlings in early June, and planting in the cultivation pot after rooting (the cultivation substrate in the cultivation pot is composed of V 垃圾土 :V 草炭 :V 鸡粪 =3:1:1), the cultivation bowl has a diameter of 19cm and a height of 15cm. Ensure sufficient water and fertilizer during the growth period, timely remove side branches, side buds, and redundant buds, and promptly wipe buds to ensure that one chrysanthemum blooms one flower, which is convenient for counting the flowering time (the day when the chrysanthemum seedlings are planted in the cultivation pot is counted as the first day). On August 15, when the height of the chrysanthemum seedlings was 30 cm, the test group used cotton balls to absorb 500 μl of 5-azaC aqueous solutions with concentrations of 200, 250, 300, 400 and 500 μmol / l, respectively, and placed them on the terminal buds of the chrysanth...

[0018] This embodiment is to test the "Quanxiang Chongtian" chrysanthemum variety. The specific adjustment method is: cutting seedlings in early June, and planting in the cultivation pot after rooting (the cultivation substrate in the cultivation pot is composed of V 垃圾土 :V 草炭 :V 鸡粪 =3:1:1), the cultivation bowl has a diameter of 19cm and a height of 15cm. Ensure sufficient water and fertilizer during the growth period, timely remove side branches, side buds, and redundant buds, and promptly wipe buds to ensure that one chrysanthemum blooms one flower, which is convenient for counting the flowering time (the day when the chrysanthemum seedlings are planted in the cultivation pot is counted as the first day). On August 15th, when the plant height of the chrysanthemum seedlings was 30 cm, absorb 500 μl of 5-azaC aqueous solution with a concentration of 200, 250, 300, 400 and 500 μmol / l with cotton balls and place them on the terminal buds of the chrysanthemum plants, and treat ...

Abstract

The invention relates to a method for promoting chrysanthemum to bloom in advance by using 5-azaC. The method comprises the following steps of: cutting and raising a seedling; after rooting, planting in a cultivation pot, and adopting the conventional cultivation management method to ensure water and fertilizer; and when a chrysanthemum plant has the height of 20-40cm, treating the apical meristem of the chrysanthemum by using the 5-azaC at the concentration of 200-500mu mol / l for 10 to 15 days, and restoring normal management. The method is easy to implement, has an obvious effect (the chrysanthemum can bloom 10 to15 days earlier), cannot generate any adverse effect on the enjoyment effect of the chrysanthemum, and is suitable for scale production in field.

Description

technical field [0001] The invention relates to a method for regulating the florescence of plants, in particular to a method for promoting early flowering of chrysanthemums by using 5-azaC. Background technique [0002] According to the natural flowering period, chrysanthemums are divided into spring chrysanthemum (flowering period from late April to late May); summer chrysanthemum (flowering period from late May to August); autumn chrysanthemum (flowering period from late October to late November); winter chrysanthemum (flowering period from early December) to February of the following year). Chrysanthemum has become the most widely cultivated variety because of its many varieties, good flower shapes, and complete flower colors. The growth and development, germination, differentiation, and flowering of chrysanthemums are closely related to environmental factors such as sunshine, temperature, and cultivation. Artificial control of sunlight and temperature on chrysanthemums...
