The method comprises the steps of growing seedlings of slow-growing shrubs, developing lateral roots, transplanting after 5 years of planting, adopting a DN1000 bio-based cylinder, wherein the thickness of a middle reinforcing layer is 25mm, the height of the middle reinforcing layer is 600mm (wherein the thickness is 200mm above the ground surface and is 400mm below the ground surface), and the density is 700-750 kg/m3The thickness of the outer protective layer is 1.5 mm; after the biological base cylinder is simulated for 5 years, the strength is attenuated to 50% -70%, the biological base cylinder can be transplanted along with plants, the biological base cylinder can play a role in positioning and protecting lateral roots after being transplanted, and after being transplanted, the biological base cylinder is rotten, and the root system is freely expanded.
Experimental example 3
The perennial herbaceous plant seedling raising method has underdeveloped root system, weak anti-interference capacity of other root systems and long-term maintenance, adopts DN600 biological base cylinder, the thickness of the middle enhancement layer is 20mm, the height of 600mm (200 mm above the ground surface and 400mm below the ground surface) and the density of 650-700 kg/m3The thickness of the outer protective layer is 2mm, and the end face is provided with an ultraviolet-proof material; after the bio-based cylinder is simulated for 5 years, the strength is attenuated to 70% -90%, and the interference of other plant lateral roots can be effectively prevented.
The strength simulation adopts an accelerated aging method.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
