Germination accelerating and seedling growing method for podocarpus macrophyllus

Abstract

The invention relates to the technical field of podocarpus macrophyllus planting, in particular to a germination accelerating and seedling growing method for podocarpus macrophyllus. The germination accelerating and seedling growing method mainly comprises the flowing seven steps of carrying out seed overwintering, carrying out primary treatment in a nursery garden, carrying out seed germination accelerating, carrying out re-treatment in the nursery garden, carrying out seeding, carrying out thinning and carrying out nutrient and water management. According to the method, podocarpus macrophyllus seeds with excellent quality are selected for germination accelerating of seedlings, firstly the seeds are mixed into wet sand for natural overwintering, then the seeds are dormant in a comfortableenvironment, so that germination and rooting at the later stage of the seeds are promoted; the seeds after overwintering are soaked through germination accelerating liquid, the germination force of the seeds is improved through effective components of the germination accelerating liquid, so that the inner disease resistance of the seeds is promoted, then the survival rate of the seedlings is increased, and the disease resistance of the seedlings is improved; and the seeds at the dormant period are effectively awakened by combining with illumination, so that the activity of internal tissues ofthe seeds is improved, and compared with a common germination accelerating effect, the method has the advantage that the germination rate of the seeds is effectively increased by 5-7 percent.

Description

technical field

[0001] The invention relates to the technical field of podocarpus planting, in particular to a method for accelerating germination and raising seedlings of podocarpus. Background technique

[0002] Podocarpus, alias Tushan, Podocarpus family, Podocarpus is an evergreen coniferous tree, up to 20 meters, diameter at breast height of 60 cm; bark gray or taupe, shallow longitudinal fissures, falling off in thin flakes; branches spread or slant , denser. Leaves spirally inserted, strip-lanceolate, slightly curved. Male cones are spicate and axillary, with several triangular bracts at the base; female cones are solitary in leaf axils, stalked, with a few bracts at the base. Seeds ovoid, round at apex, fleshy aril purple-black with white powder when ripe, seed receptacle fleshy cylindrical, red or purple-red. The flowering period is from April to May, and the seeds mature from August to September.
