Chrysanthemum varieties are many, long flowering period, is the best of ornamental flowers, such as the opening of the Spring Festival, will undoubtedly increase the festival festive atmosphere. The method for opening chrysanthemums during the Spring Festival is as follows:
Timely breeding
Chrysanthemum takes about 100 days from planting to flowering, and cutting propagation should be carried out in the middle or late August of the lunar calendar. The method is to cut 5-7 cm long shoots or branches from a strong mother plant to make cuttings and cut the base leaves. Cut and bite the mud, and then insert it into the basin sand, irrigating the water, and shading it properly. Afterwards, keep the basin sand moist. After 10-20 days of inserting, it can take root. The lunar calendar can be planted in the middle and late September.
Use good fertilizer
Chrysanthemum is a kind of short-day plant that likes sunshine, hi humidity, coolness, cold resistance, and water scarcity. Pottery-basic fertilizers should be dominated by phosphorus and potash fertilizers that control strong stalks, and nitrogen fertilizers that promote long-leaf foliage should be avoided. In order to make chrysanthemum grow short and strong, and the section is dense and leafy, the leaves are not empty, the watering should not be too much after the plant is transplanted to survive, but it is necessary to loosen the soil and weed regularly to keep the soil loose and promote the development of the root system. It is usually sprayed once a day in the morning on a sunny day, and the amount of water can be guaranteed to evaporate at noon. Leaching diluted liquid fertilizer once every 1-2 weeks, can also spray 0.3-0.4% of urea or potassium dihydrogen phosphate to promote seedlings robust. As the plant grows, the concentration of the applied liquid fertilizer can be gradually increased until it stops when budding.
Reasonable topping
In order to increase flowering branches and promote more flowering, it is generally necessary to carry out 3 picking-ups. After the colonization and survival, the main stem left two sections to start the first heart-pickup, and after about 13 days each time the two branches were left on each lateral branch. The third picking of the heart is about 68 days before the Spring Festival. The picking should not be too early or too late so as not to miss the Spring Festival flowering. In order to reduce nutrient consumption, all buds should be wiped off when the plants just sprout.
Prevent pests
Aphids are the most important pests of chrysanthemums, which have a great influence on flowering. In severe cases, they cause the leaves to wither and even the whole plant to die. Control methods: spray 40% dimethoate 1000-1500 times, or 400-600 times detergent powder (add a little urea).
