The Propagation method of Fragrance 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. Fragrant wood usually uses sowing propagation and cutting propagation. Let's take a look at the propagation methods of incense wood.

Sowing and propagation of fragrant wood

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.

1. Sowing season: either spring or autumn. Generally, 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.

2. Points for attention

① is afraid of waterlogging: the soil should be kept dry and loose as far as possible, generally not watered or watered as little as possible.

② is afraid of shade: seedling stage and time seedling, increase seedling transmittance, ventilation and ventilation.

③ is afraid of fertilizer damage: 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 seedling of fragrant wood

Cuttings can be cut in both spring and autumn. During the period when the trees are quiet, one-year-old strong branches of the mother tree are selected and cut into cuttings 1O~l5 centimeters long. The upper cut is 1.5 centimeters away from the bud and the lower cut is O.3~O.5 centimeters 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.
