Chinese lace bark pine seedling growing method

Abstract

The invention discloses a Chinese lace bark pine seedling growing method comprising the following steps: 1, seed acquisition and processing: selecting a strong 35-45 year forest tree with good trunk shape and no insect disease as a seed collection seed tree, using an improved sand storage method to process the seeds, removing the processed seeds, sinking the seeds with potassium permanganate solution, and finally doing accelerating germination; 2, sowing and seedling growing: selecting a seedling bed, applying a base fertilizer, ploughing, raking and ridging, building a shed, using a shield net to seal the shed, and using a plastic film to seal the outer layer of the shed, paving a mixture formed by biogas residue, vinegar residue and wet sands on the seedling bed, doing soil disinfection on the seedling bed, and sowing the seeds after 10-12 days; 3, seedling stage management. The method is simple and doable, low in condition dependency, can product trees in more regions, thus providing more obvious economic effect and social effects; the method can obviously improve emergence rate and seedling survival rate, can relatively reduce a seedling growing period, can do the seedling growing process in an early stage, and can improve nursery stock disease resistance ability.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for raising pine seedlings. Background technique [0002] White bark pine, also known as white bone pine, three-needle pine, and ginkgo pine, is an evergreen tree in the genus Pinus. It has strong adaptability, deep roots, and long life; it is evergreen in all seasons, elegant in tree posture, and has white scales and silver armor, which is very ornamental; it has strong resistance to sulfur dioxide and smoke pollution, and also has certain resistance to hydrogen oxide and chlorine gas. Ability, its secretion can kill harmful bacteria in a few minutes, it is a good environmental protection tree species. Over the years, white bark pine has been widely used in landscaping. It can be planted alone, opposite, or clustered into a forest or as a street tree, forming a landscape with strange peaks, which is very popular among people. [0003] With the impro...
