Abstract

The invention relates to a hole-tray sticking culture method of tea-tree seedlings, which can shorten the deliver time of tea seedlings and has high transplantation rate of the tea seedlings with a substrate. In the invention, a 50-hole forest hole tray or a 32- hole forest hole tray is adopted, and the substrate comprises 60-75 percent of peat, 23-38 percent of vermiculite and 2 percent of diammonium phosphate. The method comprises the following steps of: adopting new-grown semi-lignified twigs as cuttings; conventionally sticking the cuttings; sticking 1-2 cuttings in each hole; culturing at controlled temperature and controlled moisture; and when the seedlings are higher than 5cm, hardening the seedlings for 1 month according to practical weather conditions until the seedlings are higher than 80cm, the ground diameter is larger than 2cm, the number of primary side roots is more than 10, and the root volume is larger than 3cm<3>. The method has short seedling period, not only reduces the consumption of soil resource but also avoids the propagation danger of soil-borne pathogens by the seedlings because of adopting soilless culture, and has high tea seedlings yield rate.

Description

technical field [0001] The invention relates to the technical field of crop seedling breeding, in particular to a tea tree seedling plug cutting breeding method. Background technique [0002] The breeding of tea tree seedlings is an important material necessary for the development of new tea gardens, the transformation of low-yield tea gardens and the renewal and improvement of tea tree varieties grown in sexual groups. Most of the current clones of tea tree seedlings are propagated by cuttings. The tea seedlings in the cutting breeding nursery are out of the nursery for more than 18 months, and the land use economic cycle of the tea seedling breeding nursery is two years, which is a long period. On-site breeding is time-consuming and labor-intensive, and the cost of field management is high. The survival rate of pulling seedlings is greatly affected by the transportation process and the planting process, and the survival rate changes greatly after planting. SUMMARY OF TH...
