What are the methods of hotel greening, maintenance and drainage?

Plane hedges, pattern hedges and case hedges are all trimmed by hand to meet the design requirements. The function of pruning: first, it inhibits the growth advantage of the top of the plant and promotes axillary bud germination, then the branches grow and the walls are full, which is beneficial to pruning and shaping. The second is to speed up the molding and meet the design appreciation effect. Pruning principle: from small to large, prune many times, smooth lines, and shape as needed. Generally, the design height of hedges is 60- 150 cm, and those exceeding 150 cm are tall hedges (also called green walls) to isolate the line of sight. The technical requirements for initial cutting and pruning are as follows: when the hedge grows to 30 cm high, pruning begins. Trim it into prototype 3-5 times according to the design type. Pruning time: after the second pruning, clean the cut branches and leaves, strengthen the management of fertilizer and water, and carry out the next pruning when the new branches and leaves grow to 4-6 cm. If the interval between trimming before and after is too long, the hedge will be deformed and must be trimmed. Noon, rainy days, strong winds and foggy days are not suitable for pruning. Trimming operation: At present, large hedge shears are mostly operated by hand, requiring sharp edges to be close to the hedge surface, without missing or repeated shearing, cutting more protruding parts with strong length and less concave parts with weak length, so that straight planes can be trimmed by drawing. Hedges of various shapes (round, ground, fan, Great Wall, etc.). ) according to the type of pruning, cut more at the top and less around. Setting and pruning: when the hedge grows to meet the design requirements and is set, all new branches and leaves will be cut off at one time to maintain the design specifications.
