Papaya Begonia is a widely used plant in the garden, and now it is also very popular in the garden. So how are papaya Begonia cultivated? What's the best way to breed? What should we pay attention to when we breed papaya and Begonia? Please read on with me with questions!
Breeding methods of Begonia papaya breeding methods (basic knowledge): the best breeding time: the planting period is appropriate before germination in early spring or after falling leaves in early winter.
The best growing soil: it has wide adaptability to soil, but it requires loose soil, good permeability and low groundwater level.
Requirements for growth humidity: warm, humid and sunny environment, cold and cold resistance
The best growth temperature: cold resistance, so when is the winter is - 15 degrees below the Begonia flower or can grow very well, will not be frozen, can be placed in the outdoor winter. However, when the cold is abnormal, protective measures should be taken.
Best growth light: Begonia flowers like sunshine, suitable for growing in sunny environment, it will grow badly in cool place. Special attention should be paid to the potted plants raised in the family, and they should be placed in a place with sufficient light when they are growing.
The key points of cultivating Begonia of papaya with pink color: applying fertilizer: in autumn, after the leaves fall, a large fertilizer must be applied to supplement the lost nutrients, so that it can keep healthy. When spring buds germinate, organic fertilizer should be applied once and water should be poured once. The fertilization should be different when the age of trees is different.
Watering points: Begonia is also famous for its drought resistance, so do not water too much at ordinary times, and do not allow water to accumulate in the soil, otherwise excessive humidity will lead to rotten roots and leaves will turn yellow.
Main points of pruning: after falling leaves, Begonia flowers can be pruned once before sprouting in early spring to cut off the dead and weak branches and disease and insect branches, so as to maintain the crown evacuation, ventilation and light transmission. In order to promote the vigorous flowering of plants, it is necessary to cut the long branches short so that the axillary buds can get more nutrition, so as to reduce the nutrient consumption and form more flowering and fruiting branches. During the growing period, if the heart can be removed in time and nutrition growth is limited in the early stage, the effect is more significant.
Basin soil replacement: papaya and Begonia are also commonly used bonsai trees, suitable for making different forms of bonsai, such as straight dry, inclined dry, double dry, curved dry, near water, open root, jungle, one multi dry and so on. For the young trees, the shape is mainly made of curling and pruning, and the twists and turns of trunk processing are caused. However, the artificial traces cannot be too heavy, and the branches left should not be too dense. It is better to be sparse, so as to make them fresh and elegant. A few branches can sketch the unique charm of Begonia, and achieve the artistic effect of "from nature, but higher than nature". Before flowering, lay moss on the basin surface, and decorate stone pavilions The platform, figures and other accessories make it poetic and picturesque. For the old piles that have been growing for many years, they should be shaped according to the tree situation, and different styles of bonsai should be made. The crown can be made into regular round pieces, or natural and unrestrained. The method of pruning and rolling together can be adopted to make the branches and leaves luxuriant. Some people also process the trunk of Begonia to several bends, which is called "dragon walking style". This kind of bonsai has too heavy artificial traces, lack of natural flavor, and the shape is the same, which cannot be advocated too much.
Key points of propagation: Begonia papaya, which can be propagated by sowing, branching and cutting
Disease and pest control: the disease of Begonia papaya is mainly rust, which will cause plant death when the disease is serious. When the disease occurs, it can be sprayed with 800 times solution of 50% wettable particles of abacteria, once every 10 days, three to four times in a row to control the disease. In addition, if the soil is lack of iron and too alkaline, it will cause the leaves to turn yellow. The black alum (ferrous sulfate) water can be poured to improve the soil quality and avoid the leaves from turning yellow. The main pests of papaya and Begonia are aphids, red spiders and yellow moths, which can be controlled by spraying with 800 times solution of 50% dichlorvos or 1000-1500 times solution of 40% Omethoate.
Cultivation method of Begonia: transplanting and turning basin of Begonia should be carried out in early spring with soil lump, main root should be cut short and more lateral root should be left. The neutral to slightly acid, loose and fertile sandy soil is used for planting, and the rotten cake fertilizer is applied as the base fertilizer. After survival, it shall be placed in the outdoor sunny place for maintenance. During the growth period, the basin soil shall be kept moist without ponding. At the beginning of April, 0.2% potassium dihydrogen phosphate solution was sprayed on the leaf surface to make the flower bud strong and provide sufficient nutrition for later flowering and fruit. Due to the lack of potted soil and limited nutrients, fruit setting can not be too much. Generally, three to five fruits are left in each pot. The rest of the fruits should be removed as early as possible to avoid excessive nutrition consumption and affect the normal growth of the plant. "Alum fertilizer water" shall be applied once a month to prevent soil alkalization and make the fruit taste great. In the maintenance, the head and the heart are often picked to keep the plant shape beautiful.
After falling leaves in winter, prune and reshape the plant once, prune the dead branches, weak branches and other branches that affect the shape, and leave more strong branches, so that the next year will be full of flowers and fruits. Papaya is cold resistant. In winter, it can stay outdoors in the windward and sunny place. It's better to bury the flowerpot in the ground, or put it in the room above 0 ℃. If the temperature is too high, the plant will sprout in advance, which is adverse to the growth of the next year. Therefore, the maximum temperature should not exceed 10 ℃, so that the plant can fully rest. Turn the basin every 1 to 2 years in early spring.
