The culture method of fragrant wood

Fragrant wood is a positive tree, but it is also slightly shade-tolerant and likes warmth, which requires deep soil layer, strong germination, slow growth and long life, but the cold resistance of seedlings is not strong, so it needs to be protected in North China. The plant can withstand the low temperature of-10 ℃, like the soil with sufficient light and not easy to accumulate water. Can be used for garden shrubs and pruning. Wild in the dry and hot valleys of 1300-2300 m above sea level in central and northern Yunnan and southern Sichuan.

The culture method of fragrant wood

Qingxiang wood is resistant to drought and barren, developed root system and strong resistance. it is not only a pioneer tree species for afforestation in dry-hot valley, but also the main fuel wood in this area. Fragrant wood has beautiful tree shape and fragrant smell, has a variety of edible and medicinal functions, and has a broad development prospect. It needs to be protected in North China. The plant can withstand the low temperature of-10 ℃, like the soil with sufficient light and not easy to accumulate water. Can be used for garden shrubs and pruning.

Fragrant wood is more sensitive to fertilizer, seedlings try to apply little or no fertilizer, to avoid excessive fertility, resulting in seedling burning or overgrowth. Cuttage seedlings can be cut in spring and autumn. The technique of non-test tube rapid propagation of plants can be carried out year-round, one leaf and one bud in the growing season and one branch in the dormant period. During the dormant period, the one-year-old healthy branches of the mature mother tree were selected, and the wood with a diameter of 0.3 cm and a diameter of 10 cm was cut off, and the distance from the upper cut to the bud was 1.0 cm and 0.5 cm from the lower section.

The suitable medium for propagation is permeable river sand or perlite. Before rapid propagation, the substrate can be disinfected with chemicals such as potassium permanganate. The base of the incision was impregnated with 50ppm~100ppmABT rooting powder or indole butyric acid. The impregnation time was 12 hours and 24 hours. The suitable processing time of one leaf and one bud with leaves is 1-2 hours, shallow propagation in the intelligent nursery bed, open the system immediately. Dormant branch wood generally begins to take root in about 30 days, and leafy wood begins to take root in 15-20 days, with a survival rate of more than 95%. It is the most effective method for rapid propagation of fragrant wood at present.

The Propagation Technology of Fragrance Wood

The fragrant wood is a positive tree, but it is also slightly shady and warm, which requires deep soil layer, strong germination and slow growth, so it needs to be protected in North China. The plant can withstand a low temperature of-10 degrees Celsius, like the soil with sufficient light and not easy to accumulate water. Can be used for garden shrubs and pruning.

Artificial cultivation of fragrant wood seedlings mainly uses seed propagation, but also can use cutting propagation.

1. Sow and reproduce. The mature period of fragrant wood seeds is very close to the scattered stage. Once it is mature, it will fall off in case of wind and rain, and it is not easy to collect, or be pecked by birds and animals. When the seeds begin to show signs of maturity, the seeds should be picked back from the tree in time. The seeds of fragrant wood are wrapped in succulent pulp and are prone to pollution and mildew. The seeds collected must be immediately prepared: pile the fruit, mash the pericarp, wash it in water, thresh and discard it and dry it in the shade and store it in a ventilated and dry place.

2. Sowing season. Either spring or autumn. Generally speaking, the germination rate of autumn sowing is higher than that of spring sowing. Before sowing, soak the selected seeds in warm water with an initial temperature of about 20 degrees Celsius for 24 hours, absorb water and expand, and sprout under warm and humid conditions. The general seed consumption is 6 kg per mu.

3. Points for attention in seedling management. Fragrant wood seedlings have three fears: first, they are afraid of waterlogging. The soil should be kept dry and loose as far as possible, generally not watered or watered as little as possible. Second, they are afraid of yin. Seedling stage should be time for seedlings, increase seedling transmittance, ventilation and ventilation. The third is to be afraid of fat damage.

4. Cuttage seedling. It can be cut in spring and autumn. During the period when the trees were quiet, one-year-old strong branches of the adult mother tree were selected and cut into cuttings 1O~l5 centimeters long, with the upper cut 1.5 cm away from the bud and the lower cut 0.3 cm away from the bud. The cutting medium should choose the soil with good permeability, medium water holding capacity and neutral or slightly acidic pH value. Before cutting, the substrate should be disinfected. Soak the base of cuttings with ABT rooting powder (see instructions). The impregnation time is 12-24 hours. The cuttings were planted in trenches, and the cuttings were inserted into the soil 2 to 3 or so. Cover with plastic film after insertion, improve air humidity, fine management before rooting, and start rooting in about 45 days.

Pot maintenance technology of fragrant wood

The tender leaves of fragrant wood are red, bright, exquisite in color, slow in growth, easy to shape, have a light fragrance, purify the air and repel mosquitoes and flies. People like to use it for indoor potted plants. The selection of ideal plant material is the basis of pot production. Family potted plants mainly see the big in the small, creating a natural and fresh feeling of moving wild landscape trees into the home. Therefore, it is necessary to carefully select the young seedlings of fragrant trees with curved trunks and deformed trees and the old trees with beautiful and simple tree shapes to cultivate them in the basin, and the wild tree pockets dug in the mountains are better, but the author does not advocate it because it will cause ecological damage. After the cultivation plants are selected, according to the conception, preliminary pruning and pruning methods such as thinning and short pruning are flexibly used to remove cross branches, overlapping branches, disease and insect branches and long branches. The purple sand pot with good permeability was selected as the pot container, and the soil covered with the pot was compacted and watered to keep moisture. Because the fragrant wood likes the light to the sun, it should be cultivated in a ventilated and transparent place such as windowsill and balcony. In daily management and protection, plastic techniques such as plate, tie, twist, pressure and so on should be applied flexibly. After years of management and protection, ideal potted plants can be cultivated.
