1. The substrate for sowing and raising seedlings

The substrates used for sowing and raising seedlings must be light, loose, water-retaining, fertile and hygienic. The mixture of sand, rotten leaf soil and dung soil can be used, and the suitable ratio of soil and fertilizer is 7:3. Use horseshoe, Bauhinia and so on as base fertilizer.

The sowing must be uniform and the sowing density must be appropriate. Small seeds are generally not suitable to cover with soil. After sowing and covering the soil, the substrate can be sprayed with water by pressure spray pot or by the method of sowing water at the bottom of the basin, so that the seed is fully close to the sowing substrate. If the soil is not disinfected, an appropriate amount of fungicide can be added to the water at this time. After the operation, it is necessary to cover the glass sheet or plastic film, and under normal circumstances, it will no longer be watered after sowing; after the seedlings are unearthed, the mulch will be removed gradually, and the seedlings should be planted in time when the seedlings are crowded, so that the air circulation and sunshine will be sufficient, and the seedlings will grow healthily. When the seedlings grow to 4 true leaves, they can be transferred to 8cm × 8cm nutrition bowl. Because the first transplanting is bare root transplanting, it is necessary to dig seedlings, transplant and water at the same time, so as to avoid seedling wilting.

3. The method of cutting

In the hotbed of more than 15 ℃, cuttings can be cut at any time, and the cuttings can be soaked in the solution of rooting powder and then cut in the medium prepared in advance. After cutting, the cuttings can be supported in a small arch shed to provide proper shade. The cuttings take root in 20 days, and can be planted in 30 days.
