First, a clear design intent to understand the planting tasks Garden trees planting is part of the landscaping project, must have a deep understanding of the design intent to achieve the design requirements. If the same is Ginkgo biloba, trees should be selected for tree planting, and the tree size should be the same. The equidistant symmetry should be used when planting. When selecting landscape trees, female and male plants can be selected. The size of the tree body can be different and the planting can be different. It can be rewarded with single plants, or three or five plants can be planted together, but attention should be paid to the development space of the crown. Furthermore, the occurrence of pests and diseases caused by improper planting of mixed trees should be avoided. For instance, mixed planting of eucalyptus and paulownia will cause the occurrence of stink bugs, etc., and cypress should be kept away from jellyfish and apple trees to avoid the occurrence of rust.
Second, on-site terrain processing, fixed-point measurement and pay-off line According to the design drawings, planting site terrain treatment is an important measure to improve the survival rate of planting. Make the planting site reasonably connect with the surrounding roads and facilities, drain well, and remove the surrounding construction waste and debris. According to the construction drawing, the fixed point measurement line is the basis for designing the landscape effect. The fixed-point payouts of street trees are generally based on roadsides or on the central axis of the road and require both sides to be neat. For trees planted on the design drawings, where there is no definite planting point, especially for trees, planting areas can be identified first. The specific location is based on design considerations, tree specifications, and site conditions. Generally do not interfere with the development of inter-plant strains.
Third, excavation pits, the size and depth of the tree pit preparation should be based on the specifications of the trees and the thickness of the soil, the size of the slope, the level of the groundwater level and soil moisture conditions. Practice has proved that Tai Hang is beneficial to the growth and development of tree roots. For example, arbors with diameters of 5-6 cm have better soil quality. They can dig holes with a diameter of 80 cm and a depth of 60 cm. The average tree pit is not less than 1 cubic meter, and the bush pit is not less than 0.5 cubic meters. In areas with large sandstorms, pits are unfavorable and should be planted in small pits.
Steroids Powder name of steroids is adrenocorticosteroids. The adrenal glands of normal people secrete a certain amount of steroids every day to maintain normal physiological functions in the body, such as regulating the metabolism of blood sugar, protein, fat and electrolytes. It is an essential hormone to maintain life.
Steroid is widely distributed in the biological community of a large category of cyclopentane hydrophenanthrene derivatives, also known as steroids, steroids. Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; These compounds belong to isoprene like substances, which are formed by cyclization of triterpenes through intramolecular reorganization and chemical modification.
