Larch, Pinus sylvestris, spruce seedlings are covered with larch needles, which can neutralize alkaline and improve the soil; larch needles have hooks on their petioles and are compacted to form a unity, which helps preserve water, reduce water evaporation, and increase temperature 2~3. °C; 3~4 days before emergence, emergence is neat; the number of emerging plants increased by 8% to 16%, and reduce sunburn; soil is not compacted, strong resistance, reduce pests and diseases, not after the water "mud legs". The seedling heights of pine, Pinus sylvestris and spruce were 14 cm, 10 cm, and 3 cm, respectively, which were 4 cm, 4 cm, and 1.5 cm higher than those without pine needles. The seedlings were thick, with an average ground diameter of 0.17 cm. The increase of 0.07 cm.
Specific approach: After sowing, first thinly cover the seeds with river sand, suppress 1 or 2 times, make the seeds and the soil tightly, and then evenly cover pine needles about 1 cm, after repression, the thickness of pine needles does not exceed 0.5 cm, and finally watering Conduct routine management.
