Cutting method of Pinus densiflora
When cutting Korean pine, select branches that grow vigorously in the growing season and are free from pests and diseases, cut the branches into 5-6 cm long with scissors, and cut off the leaves at the vertical distance 1 cm from the bottom of the branches to expose the xylem, which can improve the survival rate of cutting.
When cutting Komatsu Ji Hong, it is necessary to prepare mixed soil containing coarse sand, peat, chaff ash and fairy soil according to the ratio of 4: 3: 1: 2, and a small amount of shell powder can be added, which is beneficial for plant roots to better absorb nutrients in the soil and accelerate the growth and development process of Komatsu Ji Hong.
When cutting Korean pine, the treated branches are coated with carbendazim, dried in a cool and ventilated place, and then vertically inserted into the prepared soil. At this time, it is necessary to water the soil once, keep the soil moist, put a transparent plastic bag on the top of the plant and breathe at noon every day.
Korean pine can grow normally in 15 ~ 20 days after cutting. At this time, it will be moved to an environment with scattered light and good ventilation for cultivation. In the process of plant growth, a small amount of nitrogen and phosphorus fertilizer will be applied to avoid the accumulation of organic matter in the soil, which will cause the roots of plants to burn.
