Method for raising seedlings of artocarpus heterophyllus by grafting through bud stock

The invention discloses a artocarpus heterophyllus bud stock grafting seedling raising method, and belongs to the technical field of fruit tree seedling raising. Seeds with the length larger than or equal to 2.5 cm and the diameter larger than or equal to 1.8 cm are collected in mid-to-late July. 40-60 g of compound fertilizer with the ratio of nitrogen to phosphorus to potassium being 1: 1: 1 is applied to each square meter of seedbed, and the compound fertilizer and seedbed soil are mixed and then disinfected. Sowing the seeds, and grafting when the height of the seedlings is 15-20cm and the ground diameter is greater than or equal to 2.5 mm. Current-year semi-lignified branches on the periphery of a crown are collected from the artocarpus heterophyllus tree to serve as scions. The stock is cut off at the position 5-6 cm above endosperm, and the stock is longitudinally cut by 2-2.5 cm downwards from a notch. A knife is cut at the position 0.4-0.6 cm below the scion bud, the scion is cut into a wedge shape,
