The warming temperatures in early spring, abundant rainfall, and relatively high temperatures, when the flower trees are in the process of transition from dormancy to budding, are a good season for transplanting all kinds of flowers and trees. For those plants that have been planted to produce missing plants, it is also an opportune time for replanting. Therefore, we must seize the time for transplanting and replanting. Do not miss the opportunity. Second, a reasonable fertilization, "a flower plant, relying on the fertilizer headed." The adequacy of fertilizers is an important factor in determining the growth of flowers and trees. In particular, it is even more important to fertilize the flowers and trees in poor soil. Fertilizer to prevent the roots of concentrated fertilizer. Fertilizer must be applied lightly. Human fecal urine and cake fat must be fully fermented and decomposed before being applied. At the same time pay attention to the ratio of nitrogen, phosphorus, and potassium, can not simply apply nitrogen fertilizer. Third, trimming modeling Spring is the season of various types of flowers and trees to shoot long leaves, it is a good time for modeling. Spring is the season that is most suitable for heavy shearing. At this time, various types of flowers and trees are rich in nutrients stored in their bodies. After heavy cutting, they will not only not affect growth, but will also be trimmed to reduce growth points and concentrate nutrients so that the buds that remain will germinate neatly. Robust growth. Fourth, pest control With the rise of temperature, the growth of flower buds, flowers and trees of various pests and diseases will follow. As a manager, the trees should be checked at any time for symptomatic control. At present, the chemical pesticides used for pest prevention and control mainly include: 40% of Omethoate 1000 times liquid used for aphids, pyrethroids (such as 2.5% of the enemy killed, 20% of fast killing D) 2000 times Phthoroptera-Lepidoptera insects, 20% of dicofol 800 times used for apes, 40% of omethoate used 1000 times for scale insects, but the control time must always be held in the first generation of young hatching The peak period, from mid-May to early June, is a critical period. After the pups have formed protective wax shells, it is difficult to control pesticides in general. Disease prevention and control are important to prevent disease. For those species that are prone to disease, they should be inspected frequently. Once a small number of lesions appear, we must pay close attention to spraying and prevention, but there are also some diseases. The germs have invaded as early as buds. For these diseases, it is necessary to spray and prevent the disease as soon as possible. Generally, 70% thiophanate-methyl 700-fold or 50% carbendazim 500-fold can be sprayed once every 7 days for 2 to 3 times for comprehensive control. 5. Drainage and Flood Control Spring rain is abundant, and generally more damage is caused by drought. In the south, it is necessary to prevent waterlogging from causing the roots of the flowers to die and die. Planted flowers and trees, to open a drainage ditch, promote root growth.
