After the seedling cultivation is completed, the seedlings are pulled out of the seedling tray together with the seedling matrix and transplanted to the field. Since the roots of the seedlings are with the matrix, the speed of seedling acclimatization is greatly improved. Seedling tray seedling cultivation is not only convenient for counting the germination rate, but also can prevent soil diseases and insect pests from harming the seedlings and affecting the growth of the seedlings.
