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 of opening chrysanthemums during the Spring Festival is as follows: Timely breeding of chrysanthemums takes about 100 days from planting to flowering, and cutting propagation should be carried out in the middle and late August of the lunar calendar by cutting 5-7 cm long tips from the strong mother plants. Or cuttings for cuttings, cut off the base leaves, and pruning point mud, and then insert the pot sand, irrigating the water, appropriate shading, and keep the basin sand moist, can be rooted after 10-20 days, lunar calendar 9 In the middle and late months, the plants can be planted. Chrysanthemum with good fertilizer 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 pinching to increase flowering branches, promote multiple flowering, generally three times to pick up the heart. 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. Strictly preventing insect pests Aphids are the main pests of chrysanthemums and 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).
