Method for cuttage and direct planting of sycamore old stump

Abstract

The invention relates to a method for cuttage and direct planting of a sycamore old stump. The method specifically comprises the following steps of stem cutting, cuttage, mist management after cuttage, and planting. The step of stem cutting includes the substeps that a sycamore trunk with the chest height diameter larger than or equal to 4 cm or a sycamore side branch with the branch diameter larger than or equal to 4 cm is selected and cut to obtain the sycamore old stump, wherein the height of the sycamore old stump is larger than or equal to 2.5 m. The step of cuttage includes the substepsthat the cuttage section of the sycamore old stump is soaked into a rooting agent solution and quickly dipped for 10-40 s or soaked for 2-8 h, then the sycamore old stump is inserted into a containerfilled with a cuttage matrix, and the container is placed in a cuttage greenhouse. According to the method, the sycamore old stump serves as a direct planting object, and the rooting time is greatly shortened; by controlling the cuttage process, the rooting rate and rooting speed of the sycamore old stump can be effectively increased, and the cultivation time of sycamore seedlings is shortened.

Description

technical field [0001] The invention relates to the technical field of sycamore cultivation, in particular to a method for direct planting of sycamore by cutting old piles. Background technique [0002] Platanus has a majestic shape, dense branches and leaves, cleans the air, isolates noise, and grows rapidly. It is an important shade tree and street tree in my country. It is widely used in the greening of urban or rural roads, high-end residential areas, and factory areas. Platanus as a greening tree species needs to reach a DBH > 8 cm and a height > 3.5 meters. The propagation of Platanus usually adopts two forms of cuttings and sowing seedlings. Among them, side branch cuttings are the main propagation method. The strips need to be picked at the end of autumn and early winter. It takes at least 5 years to meet the road greening standards, but the longer the side branch grows, the more difficult it is to raise seedlings. Therefore, the current side branch cuttings o...

Problems solved by technology

[0003] When large-area greening trees are needed, large seedlings are often used for transplanting. It is necessary to cut off the crown of the sycamore, and transplant the trunk with bare roots or with soil balls. This method has the following disadvantages: ①The survival rate of transplanting is low: due to the Or when transplanting with soil balls, a large number of root systems need to be cut off, resulting in insufficient absorption roots. After transplanting, new roots must be reissued to survive. The survival rate of transplanting is low, and the survival rate cannot reach 90%, which affects the greening effect;② Transplanting is limited by seasons, and can only be planted in spring and autumn. Tree planting in all seasons cannot be achieved, let alone the effect of transplanting and surviving; ③When pruning or sawing the crown of a large plane tree, usually only 3 to 5 side branches are kept. , can’t achieve full canopy transplantation, after planting, a new canopy needs to be formed to achieve shading effect, and a large number of old stems with a stem thickness of more than 4cm are often discarded as garbage, causing certain environmental pollution, and waste utilization cannot be realized
