Problems solved by technology

[0003] In the existing podocarpus cultivation, seed breeding is one of the main methods, but the podocarpus seed oil is high, which will inhibit the germination of the seeds. At the same time, the root development is slow after transplanting, and the growth is slow. After the transplantation, the podocarpus grows poorly Lush, dwarf growth, leaves are easy to wither and turn yellow

Embodiment 1

[0015] (1) Seed pretreatment: select pine seeds with good quality and full grains, treat them with alkaline solution, then soak them in 1.2% potassium permanganate solution for 1 hour, and then put them in 0.3% potassium permanganate solution Soak in formaldehyde solution for 16 minutes, then soak in 40°C water for 24-28 hours, and finally remove the pine seeds and put them in a dry environment to accelerate germination until 1 / 3 of the cracks appear. During the germination process, you need to use 35-45 Wash once with water at ℃ to keep the surface of pine seeds moist.

[0016] (2) Seedbed management: choose sandy reddish-red soil as the seedbed, deeply plow and level it, and sprinkle 50% carbendazim and 50% phoxim on the seedbed, among which, the amount of 50% carbendazim is 3g / m 2 , the spreading rate of 50% phoxim is 1.5g / m 2 , after spreading, turn the seedbed into soil for 10cm, cover the surface of the seedbed with a film after the soil is turned over, remove the film ...

Abstract

The invention discloses a podocarpus macrophyllus cultivation method, which includes seed pretreatment, seedbed management, sowing, seedling cultivation and transplanting. Podocarpus macrophyllus seeds are subjected to alkaline solution treatment prior to being soaked in potassium permanganate solution and formaldehyde solution, and thus, activity of the seeds can be improved while efficient bactericidal and antiseptic functions can be achieved, bacterial infection and mildewing of the seeds are prevented, and seed germination time can be shortened while disease and pest damage can be prevented and controlled by warm water soaking. By scientific and reasonable fertilization in sowing, nutrition demands of seedlings in growth can be met. After transplanting, a layer of river sand is laid ina planting pit to improve draining effects of the bottom of the pit, and rotting caused by high water content of the soil at the bottom of the pit can be prevented effectively. In addition, due to dissolution of a great quantity of nutrients in the laid nutrition soil into water, nutrient absorbing effects of a podocarpus macrophyllus root system are improved, and robust growth of podocarpus macrophyllus is promoted finally.

Description

technical field [0001] The invention relates to the field of planting garden plants, in particular to a method for cultivating Podocarpus pine. Background technique [0002] Podocarpus, alias soil fir, Podocarpus family, Podocarpus is an evergreen coniferous tree with a height of 20 meters and a diameter at breast height of 60 cm. Podocarpus likes warm and humid climate, weak cold resistance, strong negative resistance, and likes moist sand with good drainage It has strong adaptability to soil and can survive on saline-alkali soil. It has strong resistance to various polluting gases such as sulfur dioxide, hydrogen sulfide, and nitrogen oxides, and has strong resistance to diseases and insect pests. [0003] In the existing Podocarpus cultivation, seed breeding is one of the main methods, but the seed oil of Podocarpus is high, which will inhibit the germination of the seeds. At the same time, the root development is slow after transplanting, and the growth is slow. After th...
