How to dwarf potted chrysanthemums
Potted chrysanthemums are planted in short stature, brightly colored flowers, and the leaves do not fall off. If the plants are too high, the ornamental effect will be affected. To dwarf chrysanthemum, take the following measures:
The dwarf varieties of chrysanthemums have a wide variety of species, and most of the families are cultivated as deskhead chrysanthemums. They have the advantages of short stature, leafy leaves, large flowers, bright colors, long viewing periods, and short growth periods. The dwarf cultivars in the desk include "Xu Tao" and "Ling Bo Fairy". When selecting cuttings, cuttings should be cut from the mother plants with short internodes and thick stems in the same variety, and the resulting chrysanthemums will be relatively short.
Postponing the cutting time The conventional cutting time of chrysanthemum is from April to May, and the cutting time is postponed to shorten the vegetative growth period of the chrysanthemum and achieve the purpose of dwarfing the plant. The cultivation of multiple chrysanthemums can be postponed until mid-July, and the cultivation of monochtheria can be delayed until early August. At this time, the air temperature is high, the air is dry, and the survival rate of the cuttings is affected. The top branches with strong growth potential, thick stems, no pests and diseases, and semi-woodiness should be selected as the cuttings, leaving few leaves. Remove the lower leaves of the cuttings, leaving only the upper 2 to 4 leaves to reduce water consumption. Cut with the scissors to prevent the leaves from losing water. The base of the cuttings was immersed in a 50 ppm GGR (plant growth regulator) solution for 30 to 60 minutes. After the plug is placed in a cool place to maintain shade or shady shed to prevent direct sunlight, take a plastic shed, increase air humidity. Spray the leaves one or two times a day to keep the leaves moist. Do not allow water to flow into the basin when spraying. This not only meets the chrysanthemum's need for water, but also prevents water accumulation and causes rot.
Shallow planting and shallow planting can not only avoid the influence of high temperature and dryness, improve the survival rate of cuttings, but also reduce the height of chrysanthemum. The method is to insert the cuttings into the basin soil 3 to 4 cm, hand compaction of the soil, pouring a water permeable. After half a month, the cuttings remained green, indicating that they had taken root and survived. One month after cutting, the first transplanting can be carried out. When transplanting, it should be planted in shallow depth, and the excessive water and nutrients will lead to plant growth. After transplanting, firstly put it in a cool and shaded place to maintain it. After the seedlings are slowed, move them to sunny place and let them receive more light. The second transplant is also a shallow plant. The potted earth was first buried in about half the height of the pot, and then gradually covered with the height of the stem of the chrysanthemum, which can achieve the purpose of dwarfing the height of the plant, and causes new roots to be buried in the stems buried in the soil. The plant's ability to absorb nutrients encourages chrysanthemums to grow robustly and produce large blooms.
Control water and fertilizer cultivation Daihua dwarf large chrysanthemum, in the management of water and fertilizer must be carried out according to the principle of "pre-control and promote," that is, in the vegetative growth period should be deducted water deduction fertilizer, to prevent leggy, to achieve the purpose of plant dwarfing. In the late period of vegetative growth and the flowering stage of the pregnant buds, the amount of watering and fertilizing should be increased to promote the fullness of the flower buds, form a beautiful color and be neat and flowery. The specific approach is to control watering in the early period of vegetative growth after transplanting for the first time. It is better to make the basin soil dry slightly, and watering should be carried out before noon. Fertilizer can be applied 0.1% urea or 0.05% potassium dihydrogen phosphate fertilizer. In the later period of vegetative growth, that is, after the second transplanting, the fertilizing amount must be increased in addition to the high amount of fertilizer in the culture medium. A thin cake is applied once a week while spraying with 0.1% to 0.2% of urea or potassium dihydrogen phosphate. Before budding, watering should be carried out according to the principle of "see dry see wet". If watering is too much, it will lead to leggy. After budding, the plant height is basically determined, which can increase the amount of watering, and in combination with watering more phosphorus and potassium fertilizer, less nitrogen fertilizer to promote flower color. Stop the fertilization when the flower buds pass through, and reduce the amount of watering.
Picking the heart to pick the buds of the chrysanthemum In addition to the single chrysanthemum, generally leave 5 to 7 flowers. To reach a dwarfed plant, two heart-pickups should be performed. For the first time, after picking up the chrysanthemum to plant the seedlings, the main buds were removed on the top of 3 to 4 leaves. After budding, only one main bud with good growth and buds is left on each branch, and all other side buds are removed.
The culture medium used for the first transplant with different culture media requires loose, high permeability, and low fertility to promote multiple lateral roots of the seedlings. Can be used 40% of the leaves, 40% of the river sand and 20% of the garden made of sterile after use. The second culture medium for transplanting requires strong permeability, high fertility, and long-lasting fertilizer to meet the needs of buds and flowering. It can be prepared with 10% cooked cake, 50% rot, 35% sandy loam and 5% quick-acting phosphate fertilizer.
Spraying a plant growth regulator to spray a plant growth retardant can inhibit cell division and extension, thereby achieving the purpose of short internodes and dwarfing of plants. Commonly used hormones are BK, paclobutrazol, etc. The usage concentration is 0.1% to 0.2% compared to the long time. The method of use is: after one week of cutting, spray the top of the solution to the top of the seedlings for a long time to inhibit the growth rate of the top. One week after the basin, spray the solution for a longer period of time every 7 to 10 days. Until the buds emerge, there is no interruption in the middle. Spray time is appropriate in the evening, which is beneficial to plant absorption. Avoid spraying at noon, because it is easy to cause injury.
