Embodiment 1

[0022] 1) Take the branches of the Northeast Chinese wolfberry, with a length of 16-20 cm and a diameter of 0.8-1.5 cm. Cut the base of the branches obliquely to an angle of 40 degrees, and cut the tops of the branches flat. The branches have no stems and leaves, but they must be kept 4 or more germination points.

[0023] 2) Soak the end of the branch inserted into the substrate in clean water overnight, then take it out, and insert the branches of the Northeast Qi Liu into the leveled sand culture substrate according to the row spacing of 5.5×5.5 cm. The depth of the willow inserted into the substrate is 1 / 3, 2 / 3 is exposed, and the exposed part must have more than 2 germination points. The sand cultivation substrate used is a mixture of river sand with a particle size of less than 0.1 cm and flake vermiculite with a particle size of less than 0.1 cm that are fully washed with clean water at a volume ratio of 1:1.

[0024] 3) Pour evenly the prepared improved Hoagland nutri...

Embodiment 2

[0029] 1) Take the branches of the Northeast bark willow, with a length of 16-18 cm and a diameter of 0.8-1.5 cm. Cut the base of the branches obliquely to an angle of 45 degrees, and cut the tops of the branches flat. The branches have no stems and leaves, but they must be kept More than 5 germination points.

[0030]2) Soak the end of the branch inserted into the substrate in clear water overnight and take it out. Insert the branches of the Northeast Chinese wolfberry into the leveled sand cultivation substrate according to the row spacing of 6×6 cm. The depth of the willow inserted into the substrate is 1 / 3, 2 / 3 is exposed, and the exposed part must have more than 3 germination points. The sand cultivation substrate used is a mixture of river sand with a particle size of less than 0.1 cm and flake vermiculite with a particle size of less than 0.1 cm that are fully washed with clean water at a volume ratio of 1:1.

Abstract

The invention belongs to methods for cultivating and expanding of bush willows and particularly relates to a northeast osier branch cuttage method. The northeast osier branch cuttage method aims to solve the problems that by the adoption of an existing northeast osier cultivating and expanding technology, the anti-bacterial capacity is low, and the rate of survival of branches is low. The northeast osier branch cuttage method comprises the steps that northeast osier branches are selected, soaked and then are inserted into a sand culture matrix, the branches are irrigated with a prepared and improved Hoagland nutrient solution and the like, the braches are cultivated in a greenhouse for two mouths, the well-developed branches are transplanted to an outdoor environment with sufficient illumination and moisture on the premise that roots are not damaged, and the braches are planted according to the line space of 1-2 m * 1-2 m. By the adoption of the northeast osier branch cuttage method, the rooting time of the northeast osier can be shortened, the cultivation survival rate is increased, the germinating capacity is high, and the rate of survival of branches reaches over 87%; in addition, due to the fact that the sand culture matrix can be utilized repeatedly, materials are saved, cost is reduced, and environmental friendliness is achieved.

Description

technical field [0001] The invention belongs to a method for propagating and expanding varieties of shrub willow, in particular to a method for cutting branches of Northeast willow willow, and the technology is directly applied to the breeding and expanding of willow willow. Background technique [0002] In ecological engineering, the role of willow is irreplaceable. Willow is a unique plant on the riverside. As a natural material, it can not only play a protective role, but also has great significance for restoring the natural landscape of the river and protecting the habitat of living things. For example, the branches of willow bark willow are tough and not easily broken by wind. They are excellent tree species for dike protection. At the same time, bark willow has large and well-developed lateral roots, which can also fix beaches and slopes and improve soil. Excellent tree species for improving farmland microclimate. In addition, wicker can also be used for phytoremedia...
