Chrysanthemum has always been among the "four gentlemen of flowers" with its elegant posture and the character of Aoshuang. The chrysanthemums whose flower diameter is more than 18 centimeters--Daju, are favored by the lover chrysanthemums because of their pure color and large flowers. However, many people have bought carefully selected giant chrysanthemums, and after they have tasted some flower designs, they have no choice but to “helplessly fallâ€. They have no choice but to put Dajuku uprooted and disregard it. How to make the chrysanthemum cherished by the lover chrysanthemum open year after year, here to introduce the cultivation and management techniques of the home grown chrysanthemum. First, after the management of large chrysanthemum flowers after the Xie, the mother plant cut from the base, placed in the home cool in the cool or dry place, such as winter, the temperature of about 5 °C. After the winter cold, diligently watering, and apply liquid fertilizer to promote sprouting of sprouts. During the sprouting process, the delicate shoots are removed and the robust shoots are retained to ensure their growth potential. Second, the selection and treatment of cuttings generally from late April to early May. Since the survival rate of the cuttings with the new sprout is low, and the growth is slow and weak, it is necessary to select the sprouts with strong growth potential for cuttings. It is advisable to use a cutting length of 10 cm, remove the lower leaves, use a pot with good water permeability to hold a light sandy soil, or use a suitable amount of river sand as a medium in the garden soil, insert the cuttings gently into the pot, and bury the depth in full. 1/3 of the degree, fully compacted around. Third, post-cutting management to keep the soil moist. When not rooting, diligently water the plants. Spray water to the leaves 2-3 times per day within 4-5 days after inserting. After rooting, reduce the number of waterings in order to stimulate root development and facilitate the growth of roots. Generally about two weeks can take root. IV. Seedling management 1. Soil selection and water and fertilizer control rooting i weeks later, the small seedlings transplanted 13 cm, plus appropriate sand and ash, control watering to prevent the roots and leggy rot seedlings, chrysanthemum seedlings grow to grasp the amount of fertilizer. Avoid excessive fertility, soften the seedlings, generally based on thin liquid fertilizer. 2. Topping the heart is an extremely important procedure in the nursery stage. Limiting the flowering number is a necessary means to promote the hypertrophy of the big chrysanthemum flower. When the seedling height is about 12 centimeters, it will be picked up once. After the growth of its lateral branches, leave 3-5 branches and all others are removed. If the lateral branches are stretched too long, they can be plucking again to make them grow and blossom. Usually 3-5 flowers per plant is the most appropriate, and more than 6 to 7 flowers. Picking up the heart must grasp the time. If it is too late, it will cause the flowering branch to be too long. If it is too early, it will cause the flowering branch to be too short, which will affect Guan Guan. V. Planting period and flowering period management Change the basin from late June to early July, when the collateral grows to about 18 centimeters, change into a large basin about 26 centimeters. The pelvic floor will be soil manure or decomposed manure. 2. Fertilizer and fertilizer can be selected from dry soil fertilizer and decomposed bean cake liquid. The frequency of application of dry manure should not be excessive, and the frequency of liquid manure can be slightly increased. Summer fertilization should be stopped during high temperature or flower bud differentiation. 3. Watering chrysanthemums need a large amount of water, and watering should be more time-consuming. In summer, it is watered 2-3 times a day, and often sprays water to the leaves after sunset. After the occurrence of buds, more water is needed. Drought can cause chrysanthemum to fall off. 4. After the lateral branches of the stand are stretched, the axillary buds should be removed at any time and a stand should be erected to prevent the fall of the chrysanthemum forest. 5. From the late September to the first ten days of the bud, multiple buds often occur on the top of the stem, and the largest one should be taken in the middle of the bud. The rest of the buds gently press down with their fingers from the side and avoid damaging the central bud. 6. Light regulation Chrysanthemum begins flowering in October. The pots should be placed in high temperature and light, and the intensity should be adjusted due to different colors. White and green flowers, avoid light is too strong, so as to avoid abnormal colors, affect the quality. When it is open to 78%, move the flowers to a cool place to extend the flowering period. 7. Diseases and Insect Pest Control Chrysanthemums are prone to aphids and other pests and diseases. They should always be concerned about, timely prevention and treatment, treatment of small governance early. Suitable concentrations of dimethoate, dichlorvos, and pyrethrum have good control efficacy.
