A plant non-soil transplanting method comprises a first step of cutting a root, removing the soil, and reserving a root system length at a proportion of three times of a tree base ground diameter; a second step of washing the root and a trunk clean, and carrying out bactericidal treatment on the root and the trunk by using a bactericidal agent; a third step of soaking the root by using a rooting agent; a fourth step of carrying out cut treatment on cuts of the trunk; and a fifth step of carrying out transplanting water retention treatment on the trunk and the root. The method is simple to operate and high in practicability. Through the procedures of washing, bactericidal treatment, rooting agent treatment, cut treatment and water retention treatment, carried out in turn, a transplanted plant can completely break away from dependence on the soil and can also has great viability; a user can totally transplant plants without soil balls under the condition of ensuring a transplanting survival rate; and the labor intensity is reduced, the carrying efficiency is raised, water and soil losses are effectively contained, and requirements for environment protection are met.

The invention discloses a method for hardening seedlings of hybrid orchid tissue culture seedlings, which includes the selection of tissue culture bottle seedlings, treatment of small seedlings, cultivation of small seedlings, transplanting of medium and large seedlings and post-transplanting management procedures, selection of vigorously growing hybrid orchids that have taken root Tissue culture seedlings, wash and disinfect their roots, soak them in nutrient solution for 20-24 hours, transplant them into a seedling container equipped with a seedling substrate and cultivate them for 4-6 months to obtain medium and large seedlings, and then transplant the medium and large seedlings on the cultivation site The seedlings were hardened in the cultivation medium, and the hybrid orchid seedlings were obtained through watering and fertilization and management after transplanting. The number of new leaves of orchid seedlings obtained by the present invention, the increment of new roots, the increment of average root length, the increment of plant height and other parameters have high values, which effectively improves the transplanting survival rate of orchid hybrid tissue culture seedlings, improves the quality of potted plants, and has a relatively high Good economic benefits.

The invention provides a tomato seedling raising method. The method includes the steps of soaking tomato seeds in warm water; according to the growth demands of the tomato seeds, selecting seedling raising plates; filling the seedling raising plates with nutrient soil, applying water to the soil, and keeping the nutrient soil wet; planting the tomato seeds in the seedling raising plates, and covering the tomato seeds with the nutrient soil; maintaining the nutrient soil wet, and after the tomato seeds germinate, applying water and frass different in amount at the different time periods; when tomato seedlings are 25-35 days old and every leaf center is surrounded by four leaves, conducting field planting on the tomato seedlings. By adopting the provided tomato seedling raising method, the germination rate of the tomato seeds is high, the seedling raising time is short, and more robust tomato seedlings can be obtained; the survival rate of the transplanted tomato seedlings is ensured; moreover, the frass of yellow mealworms is more environmentally friendly and free of smell compared with other fertilizer, and a novel approach is provided for seedling raising of the tomato seeds.

The present invention relates to tissue culture for fast propagation of plant, and is especially the indoor hardening off process of tissue cultured poplar seedling. The indoor hardening off process before transplantation of tissue cultured poplar seedling into green house includes culturing rooted tissue cultured poplar seedling to over 3 cm in abacterial condition, then indoor culture under the conditions of illumination intensity of 3000-5000 Lux for 7 days for over 14 hr each day and air humidity over 60 %, and gradually opening the bottle cap in the 7 days.
