Fragrant wood breeding technology

Fragrant wood is a family of lacquer trees and genus Pistacia. Evergreen shrubs or small trees, leaves with even pinnate compound leaves, with fragrant, red leaves, delicate, growth habits and cultivation characteristics are very similar to Pistacia chinensis, fruiting period from August to October, the fruit was red. Fragrant wood is a positive tree, but it is also slightly shade-tolerant, warm and requires deep soil; strong germination, slow growth, long life, but the cold resistance of seedlings is not strong, in northern China need to be protected. The plants were able to tolerate temperatures below minus 1 degree Celsius, and the soil was well lit and water was not easy to accumulate. Can be used for garden shrubs and cuttings.
Artificially cultivated Qingxiang seedlings mainly uses seeds for propagation, and cutting propagation can also be used.
1, sowing breeding. Fragrant wood seed maturation period is very close to the season. Once it is mature, it will fall off in the event of rain, and it will not be easily collected or eaten by birds or animals. When the seed begins to show signs of ripening, the seeds are harvested from the tree in time. The seeds of the fragrant wood are wrapped in juicy pulp and are susceptible to contamination and mildew. The harvested seeds must be immediately brewed: heaping fruit, smashing the peel, Rinse the water for washing, threshing and discarding the mixture, then dry it in a dry and ventilated place.
2, sowing season. Spring and autumn are acceptable. Generally, the germination rate of autumn sowing is higher than that of spring sowing. Before sowing, the selected seeds were soaked in warm water at an initial temperature of about 20 degrees Celsius for 24 hours. The seeds were swollen with water, and the germination was carried out under warm and wet conditions. The average amount of 6 kg per mu is used.
3, seedling management precautions. There are three fears of Qingxiang wood seedlings: First, they are afraid of blisters. The soil should be kept as dry and loose as possible, generally not poured or watered as little as possible. The second is the fear of yin. Seedling time and seedling time, increase seedlings transmittance, ventilation and ventilation. The third is the fear of fertilizer damage. Fragrant wood is more sensitive to fertilizers. Seedlings do not fertilize or even apply fertilizer as much as possible. Avoid excessive fertility and cause seedlings to sprout or grow.
4, cutting seedlings. Spring and autumn can be cut. During the period of the fallout of the trees, the strong mother tree was selected to be one year old and cut into 10 to 15 cm long cuttings. The upper cut was 1 to 1.5 cm from the bud, and the lower cut was 0.3 to 0.5 cm from the bud. The cutting matrix should have good permeability, medium water hold, and neutral or slightly acidic pH. Prior to cutting, the substrate should be disinfected. The cuttings were impregnated with ABT rooting powder (used in the instructions). Immersion time is 12 to 24 hours. Ditch the plant and insert the cuttings into the soil about 2/3. After covering the plastic film, improve the air humidity, carefully manage before rooting, and begin rooting around 45 days.
