The propagation method of the latest fragrant wood

Qingxiang wood is a positive tree, but it is also slightly tolerant of shade, likes warmth, requires deep soil layer, strong germination, slow growth, long life, but the cold resistance of seedlings is not strong, and needs to be protected in North China. Plants can withstand-10℃ low temperature, like sufficient light, not easy to accumulate water soil, Qingxiang wood usually uses sowing propagation and cuttage propagation, let's take a look at the propagation method of Qingxiang wood!

Sowing and propagation of fragrant wood

The mature period of seeds is very close to the scattering period. When they mature, they fall off in case of wind and rain, and are not easy to collect, or they are pecked by birds and animals. When the seed begins to appear mature signs, the seed shall be collected from the tree in time. The seed of Qingxiang wood is wrapped in juicy pulp and is easy to be contaminated and moldy. The collected seed must be prepared immediately: the fruit shall be piled up, the peel shall be smashed, the water shall be washed, the impurity shall be threshed and dried in the shade, and the stored in a ventilated and dry place.

1, sowing season: spring and autumn can be, generally autumn germination rate is higher than spring sowing. Before sowing, the selected seeds are soaked in warm water at an initial temperature of about 20 DEG C for 24 hours, the seeds absorb water and expand, and are taken out and placed under warm and humid conditions for germination. Generally, the seed amount per mu is 6 kg.

2. Precautions

① Fear of waterlogging: The soil should be kept dry and loose as much as possible, and generally not watered or watered as little as possible.

② Fear of shade: seedlings should be thinned in time to increase the transparency of seedlings and ventilation.

③ Fear of fertilizer damage: Qingxiang wood is sensitive to fertilizer, and the seedlings should be fertilized as little as possible or not fertilized, so as to avoid excessive fertility, resulting in seedling burning or excessive growth.

Cuttage propagation of Aralia fragrans

Spring and autumn can be cuttage, in the rest of the trees, select the mature mother tree 1-year healthy branches, cut into 10 ~ 15 cm long cuttings, the upper incision from the bud 1 ~1.5 cm, the lower cut from the bud 0.3 ~ 0.5 cm. The medium with good permeability, medium water holding capacity and neutral or slightly acidic pH value was suitable for cuttings.

Before cutting, the substrate should be disinfected. Soak the base of cuttings with ABT rooting powder (use according to the instructions). Immersion time is 12~24 hours. Trenching and planting, cutting into soil about 2/3. Cover plastic film after insertion, improve air humidity, fine management before rooting, rooting begins about 45 days.
