Five needles pine is a tree species with high ornamental value, which is not only suitable for garden decoration, but also an important tree species for potted plants or bonsai. In order to maintain a good tree posture, control the growth of branches and leaves, and achieve short, filial, dense and healthy shapes of branches and leaves, it is necessary to carry out regular plastic pruning. When the buds of Pinus quinquefasciatus are elongated, the buds are moved from 1/2 to 1/3, which can avoid germination, make the lateral buds grow evenly and healthily, reduce nutrient consumption, and achieve vigorous and beautiful trees.

Five-needle pine likes warm and humid environment and has high requirements for light. The planted soil can't accumulate water and has good drainage and air permeability. If fertilizing, it is best to use organic fertilizer.

Soil requirements

Strict disinfection In order to prevent the shoots from rotting due to poor ventilation, it is required that the inserted soil should have good air permeability and water retention. 70% yellow soil (or mycorrhizal soil), 20% fine river sand and 10% rice bran ash can be used after sieving and mixing.

control humidity

Watering pine needles once immediately after cutting can not only make soil insertion closely connected with incision, but also improve soil moisture. Covering the shed or arch shed with plastic film and spraying or spraying water in the shed can improve the air humidity. The amount of water sprayed should not be too large, especially if there is no water in the inserted soil, otherwise it will easily lead to the death and decay of the lower end of the cuttings. Generally, it is advisable to spray water 2 ~ 3 times a day, and it can be sprayed 3 ~ 4 times at high temperature.

Adjust lighting

Five needles pine cuttings need sunlight to take root and grow. However, if the light is too strong, it will easily lead to too high temperature and burn the cuttings. Too little light, weak photosynthesis, weak rooting ability and slow growth of cuttings. Sun-shading net is commonly used in production. That is, in the early morning and evening, open the sunshade net to let the sun shine, and cover the sunshade net during the strong sunshine period of 7:30- 19:00 to prevent the sun from burning the seedlings.

Cutting time

Cuttings are suitable for cuttings from May to August, and the specific cutting time of each tree species should be determined according to the lignification degree of cuttings to achieve semi-lignification. Short, plump and robust semi-lignified shoots should be selected for cutting on young mother trees with strong growth and no pests and diseases.

environmental control

Humidity and light intensity provide suitable environmental humidity and rooting temperature, which is the key to the success or failure of softwood cutting of Pinus pentaphylla. The relative humidity of air is 80% ~ 95%, the temperature is 65 08℃ ~ 28℃, and the lighting conditions are suitable for the softwood cutting of Pinus Wutai Mountain.

hormone therapy

Treating shoots with plant hormones such as ABT rooting powder, indoleacetic acid and naphthylacetic acid before cutting can greatly improve the survival rate of cutting. The most commonly used and effective hormone in production is green plant growth regulator (GGR). Its application method is to prepare GGR into 50ppm solution, and then soak the base of cuttings in this solution for 3 to 24 hours.
