Embodiment Construction
[0016] When the temperature is stable and exceeds 15°C, such as in Henan, start seedling cultivation in early April. First of all, seedbeds and greenhouse sheds should be established. The size of the greenhouse shed depends on how many seedlings are raised. Due to the thick seed coat and poor water permeability of cotton seeds, the problem of shelling cotton seedlings must be solved first in potless seedling cultivation. Using sand, coconut powder, vermiculite, etc. or a combination of them as the medium substrate can effectively solve the problem of cotton seedlings. The problem of seedling breaking shell. On the seedbed or the seedling tray in the greenhouse shed, evenly lay the substrate layer based on the above substrate, the thickness of the substrate layer is about 4-6cm. Sow the selected cotton seeds in the sun, so that the germination rate of the seeds can reach more than 95%, and sow them on the seedbed or in the seedling tray, and the seeding rate on the seedbed is...
