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...

Problems solved by technology

[0005] The technical solutions disclosed in the above two reports can improve the emergence rate and seedling quality, but when dealing with white bark pine planting, such as sand storage, the conventional method is adopted, that is, the seeds are buried in wet sand for germination, and the seedbed is only used for sterilization Disinfection treatment does not optimize the organic matter content of the seedbed. Although this can relatively improve the emergence rate and seedling quality, it takes a long time from sowing to emergence, usually about 25 to 30 days, and has a negative effect on the survival rate and seedling resistance quality. The improvement is limited, and there are still defects of low efficiency
