Embodiment 1
[0017] (1) Choose a plot with fertile soil and good terrain to plan the cutting seedbed. The seedbed is extended from east to west, with a bed surface of 1.3m wide and 5m long, and the bed surface is slightly higher than the ground surface. The bed soil is raked and loosened and flat. The surface substrate of the seedbed is mainly the vegetable seedling substrate of Pinshi, supplemented by river sand, with a volume ratio of 4:1, mixed evenly, and spread on the surface of the seedbed, with a thickness of 4-7cm. The substrates prepared by the two have good air permeability And water retention;
[0018] (2) The arch shed is made of steel (or bamboo), with a height of 0.8m, a width of 1.4m, and a length of 5m. The top of the arch canopy is covered with double-layer polyethylene non-drip film, and a shade canopy is set up about 0.4~0.5m from the top of the arch canopy. The shade canopy is composed of iron brackets, iron wires and black shade nets;
[0019] (3) At the beginning of June,...
Embodiment 2
[0026] The time of fake planting and colonization is selected from late November to early December. The cutting and transplanting time at this time is later than that in Example 1, and the rest of the seedling raising process is the same as in Example 1. If the transplanting time is late, the plants will grow stronger and can be planted directly to the breeding field without fake planting.
