Planting method of seedlings of liquidambar styraciflua

Abstract

The invention discloses a planting method of seedlings of liquidambar styraciflua. The method comprises the following steps: (1) mixing sandy loam, humus soil, biogas residue, turf and peat soil according to a proportion of 2 to 1 to 2 to 1 to 1 to obtain mixed soil, wherein the peat soil is pitch peat; (2) spreading out the mixed soil obtained in the step (1), and digging out shallow pits with depths of 2-5cm according to the line spacing of 35-45cm and the plant spacing of 40-60cm; (3) preparing seeds, sowing the seeds in the shallow pits obtained in the step (2), and then covering the shallow pits with the mixed soil obtained in the step (1), wherein the thickness of covering soil is 2-3cm; (4) carrying out daily management such as irrigating, weeding, fertilizing, and pest control until the seeds grow into seedlings. The planting method creates healthy, stable and good growth conditions for the seedlings of the liquidambar styraciflua, thus shortening the growth cycle of the seedlings, greatly improving the survival rate, lowering the production cost and greatly increasing the planting efficiency.
