In winter, some of the flowers and bonsai that are more resistant to cold can be allowed to live naturally in the winter, but do not ignore the cold and warmth of these flowers and trees, especially the potted plants and bonsai pots that are used for wintering outdoors. Root system. The southern species shifts the seedlings to the north and the perennial flowers that are not tolerant to cold must be protected against cold to avoid cold damage.
Planting plants outdoors to prevent cold. Bitao, plum blossom, waxy plum, eucalyptus, magnolia, etc., can be used straw, wheat straw, rags, old cotton and other warmth to protect the stalk parts warm. In the early winter, ditches can be made around the roots of these flowers and trees, and once the fertilizer is poured, the soil can be protected by the earth. It is also possible to apply a method of whitening flowers and branches that are used for wintering outdoors, not only effectively preventing freezing damage, but also preventing and controlling diseases and insect pests that remain on branches. However, it should be noted that with the whitening agent formulated with quicklime, quicklime must be converted to hydrated lime before use, otherwise it will burn flowers and trees branches. The proportion of the whitening agent is: 36 to 40 parts of water, 10 to 20 parts of quicklime, 1 to 2 parts of salt, 2 parts of clay, and 2 parts of lime sulfur stock solution. Quickly dissolve the quicklime and salt and mix it with lime sulfur and clay. Stir evenly and whiten the coating. The amount of whitening should not be downstream.
Outdoor cold-resistant herbal flowers protect against cold. Cosmos, cineraria, pansy, kale, poppy, etc., such as winter cold weather and rain and snow, can be covered with plastic film, warm grass and other warm objects, until the weather is clear and then opened, so that The seedlings are short.
The cold flowers of the bulbous flowers. Canna flower, dahlia and other bulbous flowers need to be covered in outdoor underground winter, can be used compost soil, rot leaves, rotten grass and other coverage, pay attention to make the bulb under the frozen soil layer, otherwise it will freeze the bulb, spring will not sprout new buds next year. Note that the covering must not have an insect source.
Tall garden plants are cold-proof. High-drying garden plants such as high privet privet and yellow hawthorn can be wrapped with straw ropes in their trunks and large branches, and a strip-shaped film with a width of 10 to 20 cm can be wound clockwise from the bottom to the outside of the straw rope to prevent plant trunks. And large branches occur frost damage. For the cold-resistant potted plants and bonsai outdoor thermal insulation, the best method is to even bury the pot below the outdoor frozen soil layer, so that the root system from frost damage; followed by covering the pot surface with ash, not only the insulation effect is good, but no side effects on flowers and trees . In those years, cuttings of flowers and plants survived. Because of their small size and poor resistance to cold, in addition to allowing the main branches and leaves to receive sunlight, the remaining branches should be covered and covered with warmth, and some of the potted soil should be covered with plant ash or other insulation to keep warm.
Several other technical measures. One is the timely filling of frozen water. When there is a lack of water around the seedlings in winter, it is prone to frost damage. Therefore, it is necessary to timely seal the frozen water before the soil is frozen. In addition, the specific heat of water is larger, and more heat can be absorbed during the day to increase the ground temperature. The second is to increase organic fertilizer. The fertilization of wintering plants and flowers outdoors is generally a dormant state for flowers and trees in winter and no fertilization is required. However, some flowers and trees bloom early in the winter or the following spring, such as waxberry, plum blossom, blue peach, forsythia, etc., and some organic fertilizers can be applied to these flowers and trees in the early winter, such as composting of livestock, poultry excreta, and rot leaves that have not been fully matured. Soil, covered in the base of the flowers and trees, one can keep warm, two can increase fertility, to pregnant, flowering flowers and trees to increase nutrition, pregnant buds blossom well. Digging 3 to 4 holes in the outer part of the canopy, with a depth of 50 to 100 cm, applying horse manure, smashing the grass and other breweries and fertilizers to increase the ground temperature. Organic fertilizers release heat and increase soil fertility. In combination with fertilization, the plants should be earth-cultivated to cover the root neck, forming a conical small mound, which can protect the roots and necks that are prone to frost damage and can safely pass winter. Third, pay attention to pruning. Due to the cold winter, the pruning of winter dormancy and flowers (such as rose, crape myrtle, etc.) should be postponed until the spring temperature rises and the flowers and trees have not yet been budded to prevent the shoots from being frostbite and affecting growth. Pruning can also be carried out in the current year, but the branches should be properly left longer. When the temperature rises, it will be cut again and the long and frostbite sections will be cut off. Evergreen flowers and trees (bush melons, dwarf flowers and cypresses) should be timely pruned, which can increase winter ornamental value, but also reduce transpiration and improve plant resistance to cold.
