Seedling culture method for garden green plants

Abstract

The invention discloses a seedling culture method for garden green plants. The method includes the steps of firstly, cleaning seeds, selecting full seeds, and airing the selected seeds in a shady and ventilated place; secondly, soaking the aired seeds with warm water for 24 hours, sterilizing the seeds with alcohol, and soaking the sterilized seeds with a gibberellin solution for 48 hours; thirdly, placing the seeds with dormancy being broken in a place with temperature being 25 DEG C, relative humidity being 80% and light intensity being 3000Lx, and alternating between illumination for 48 hours and darkness for 24 hours until the radicles of the seeds are about to emerge; fourthly, loading sieved matrixes into a seedling tray, flattening by scraping, placing a seedling tray on the upper portion of the seeding tray in an overlapped manner to perform hole compression, and showering the seedling tray under running water for 10 minutes; fifthly, sowing 1-2 germinated seeds obtained in the third step into each hole, and covering the seedling tray with a layer of the matrixes. The seedling culture method has the advantages that the seedling culture time is shortened, the average seed germination rate is increased to above 85%, and qualified seedling percentage reaches above 95%.

Description

technical field [0001] The invention relates to the field of growing seedlings in gardens, in particular to a method for raising seedlings of landscaping plants. Background technique [0002] There are following disadvantages in the traditional plant nursery nursery technology: (1) in seed cultivation, there is generally a low germination rate, according to statistics, the germination rate is between 13% and 80%; (2) limited by seasons and techniques, seeds All have a storage period of about 4 months, which prolongs the cultivation period of seedlings; (3) the density of seedlings in the nursery is not uniform, and the seedlings are easily squeezed in the later stage, which affects the quality of seedlings; (4) when the seedlings go out of the nursery, they must Transplantation requires one more transplanting process, and the root system of the seedlings must be damaged during the transplantation process, which will cause the death of the seedlings in the later stage and red...
