The spring shrubs and shrubs of flowering shrubs directly affect the flowering, the quality of the results and the post-flower growth. In daily management, the following points should be grasped:
1 Watering should not be late as soon as possible. The spring temperature rises quickly but is not stable. Watering in early spring can effectively reduce the ground temperature and delay the sprouting of trees. Watering too late can easily lead to freezing damage to the plants and affect the quality of flowering. It is also unfavorable for pollination and fruit setting. The northern region is generally better in early March. Watering can also supplement the moisture in the soil at any time. After spraying, 800 times of new high fat film should be sprayed in time, which can effectively prevent large amounts of evaporation and large transpiration of plants in spring and wind, which can enhance soil conservation and reduce the number of watering.
2 Trim to be suitable at the time. For most flower shrubs, early spring is the best time for pruning. At this point the sap has not yet flowed, pruning will not cause damage to the tree, and the temperature is increasing day by day, and the wound will heal quickly. The flower shrub should be trimmed in early spring. After the pruning, the tree general must be sprayed with 500 times fluid and 800 times the new high-fat membrane to prevent virus infection. It is necessary not only to eliminate intersecting branches, pendulous branches, diseased and diseased branches, inner litchi and dead branches, but also to cut short some of the longer flowering branches, and also to biennial branches that affect the tree shape and are not left as flowering branches. Conduct sparse. Maintain tree nutrient supply and better tree shape. When the flower buds appear, it is necessary to spray flowers Zhuang Ti Ling in time, which can promote strong buds, petal hypertrophy, beautiful flowers, rich flowers, and prolonged flowering. In order to promote flower bud differentiation at the right time during the flowering period, it can promote flower bud differentiation, avoid excessive consumption of nutrients, cause fruit drop or poor fruit development, and ensure that more flowers bloom in the coming year.
3 Reasonable fertilization. In the spring, the growth of flowering shrubs is prosperous. At this time, fertilization can timely supply the flowering, fruit and growing nutrition of the plant. To do a reasonable allocation of nitrogen, phosphorus and potassium fertilizers. For some fruit and flower shrubs, it is necessary to spray strong fruit tingling at the bud stage, young fruit stage, and fruit expansion stage to increase the fruit pedicle and increase the amount of nutrient delivery. Anti-dropping, fruit drop, cracked fruit, stale fruit, malformed fruit, make the fruit beautiful and beautiful, and improve the ornamental.
4 Pay attention to pest control. In the spring, all things are awakened and the vitality is strong. Therefore, pests and diseases have also entered a prolific period. Prevention and treatment of pests and diseases should be started early and early prevention and early treatment. The pests that often occur in spring include spider mites, scale insects, aphids, leaf-cutting bees, aphids, hook moths, leaf roller moths, etc. The main pests are peach, plum, cherry, apricot, redbud, eucalyptus, stick stem, magnolia, wax Mei and other flowers. According to the occurrence of the situation in time according to the requirements of quality assurance use speed sacrifice, deltamethrin and other drugs + 800 times the new high-fat film for control. Diseases that are prone to occur in the spring include plastic gum disease of peach, plum, cherry, and apricot, leaf punch disease of peach, purple leaf plum, leaf spot disease, and leaf spot disease of peony. For these diseases, the principle of prevention should be taken. In the early spring, general tree-protection or thiophanate-methyl, lime-sulfur mixture and other fungicides + new high-fat membranes are used to prevent and control turbid fluid and stalk rot.
High flow oxygen therapy (HFNC) is a kind of oxygen therapy that directly transports a certain oxygen concentration of air oxygen mixed with high flow gas to patients through a soft nasal cannula. Also known as transnasal high flow oxygen therapy, high flow humidification oxygen therapy. HFNC has unique physiological effects: Constant oxygen concentration, Good effect of temperature and humidity, To flush the dead space of the nasopharynx, Give some positive airway pressure, Good comfort.
