Maintenance of landscaping trees
As the saying goes: "Three minutes and seven minutes", many units often have high standards for planning and design, and low levels of construction and maintenance during landscape greening. In the maintenance and management of garden trees, we must understand the type of tree planting and the characteristics and characteristics of each species. The key is to do a good job in the maintenance and management of fertilizer, water, disease, insects, and shear.
One, trim.
In order to maintain good plant growth, robust development, beautiful shape, ventilation and ventilation, reduce the occurrence of pests and diseases, timely flowering results, we must promptly pruning and nurturing. Normal pruning should be carried out after falling leaves in autumn or before budding in spring. Pruning branches and sick branches should be done at any time. For pruning of deciduous trees, keep the central trunk and properly trim the lower lateral branches. The height of branches is not more than 2.5 meters. The height of the same branch is roughly the same, once a year; the trimming of evergreen trees is mainly airy and light-transmitting. Potential, maintain natural posture, during pruning, pruning incision should be smooth, and flush with the trunk, to prevent damage to the trunk, sorghum prominent and canopy sizes; all kinds of flower shrubs, according to the growth and development of flower plants, The flower bud differentiation category or flowering category is trimmed to extend flowering and promote flowering results. After the flowering period, the flowering shrubs are timely pruned by dry branches, and the visual beauty must be ensured. The flowers, trees and grass are clearly structured, and each winter and summer are pruned once.
Second, weeding weeding.
The depth of the cultivator depends on the depth of the seedling roots and the growth period. The depth of the cultivator is generally 35 cm and the depth is about 10 cm.
Third, watering, fertilization.
Irrigation should be different according to tree species, growth conditions, and seasons. During spring drought, autumn drought, and drought, it is necessary to pay attention to timely watering, winter irrigation should be thorough, and timely irrigation after fertilization. Watering should follow the principle of “not pouring, pouring it with waterâ€. For the shrubs and shrubs with poor soil and poor growth, apply organic or compound fertilizers to promote their growth. When individual green plants appear withered and yellowed due to lack of fertilizer, special measures must be taken to carefully manage and fertilize them. Before fertilizing, the types and quantities of fertilizers used must be examined and approved by the owners before they can be put into use. For soils with poor soil structure, organic fertilizers are mainly used to improve the soil to promote plant growth. The shrubs and shrubs are applied once a year, and flowering shrubs are used no less than twice a year.
Fourth, pest and disease control.
For the prevention and control of pests and diseases, we must focus on prevention and carry out comprehensive prevention and control methods that combine various pest control measures. Once pests and diseases have occurred, it is necessary to implement the prevention and control policy of “treat early, treat small, and treat the diseaseâ€, remove the weak and disease-causing green plants in time, prevent the spreading of disease conditions and insect pests, and ensure the normal growth of other green plants.
In Hengshui Region, due to the cold weather in winter, nursery stocks are in dormant period. The conservation measures at this stage are different from other seasons. The specific measures are as follows:
1. Increase the cover. At night or on frosty days, cover the cold cloth above the low flowering shrubs to avoid direct contact between seedlings, leaves and frost and snow, reduce frost damage, and increase the temperature by 1°C2°C. When covered, bricks and stones are tightly pressed around and the cover is removed during the day. For the tall plants, 34 piles can be made around it, and the plants can be enclosed with a cold cloth and then stitched with a string to form a cylindrical shape and a shade net is placed on top. In sunny days, the cold-proof cloth can be lifted from the bottom up to allow the plants to receive the light and increase the surface temperature.
2. Increase the windings. For the high-drying garden plants, a straw rope can be wrapped around its trunk 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 freeze damage to trunk and large branches of the plant.
3. Pouring frozen water in time. 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.
4. Add organic fertilizer. Dig 34 deep 50-100 cm holes around the canopy and apply fertilizers such as beef and sheep manure and broken grass to increase 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.
