Seedling method for improving emergence rate of malus toringoides seeds

Abstract

The invention discloses a seedling method for improving the emergence rate of malus toringoides seeds. The seedling method comprises the steps of when malus toringoides fruits turn red or dark red, collecting the malus toringoides fruits, drying full seeds obtained from the malus toringoides fruits in shade in a room, packing the seeds into a sack, and storing on a ventilated place; carrying out after-ripening on an embryo after cold stratification; carrying out deep-ploughing in a selected nursery land for one time in the winter of the last year, and making a seedbed which is lightly protruded in middle according to 120cm width, 10cm height and about 25cm width of step ditch; loosening soil in the last ten-day period of March of the next year, applying a composite fertilizer as a base fertilizer, and disinfecting the soil; seeding through an artificial sowing way, covering with humus soil, completely watering for one time, building a plastic tent for preserving the heat and covering in a moisture-preserving manner; and after seeding, keeping the seedbed wet, removing a mulching film in real time when buds begin to hump, and carrying out final-singling by a plant spacing of 8-10cm when 4-6 true leaves appear on each of the seedlings. The seedling method adopts a manner of directly seeding after adopting the cold stratification for one time, is simple and easy in operation, and reduces seed usage and seedling cost; and the seed emergence rate is greater than 60%, so that the seedlings are stronger in growth.

Description

Technical field [0001] The invention belongs to the technical field of plant seed propagation, and in particular relates to a seedling raising method for improving the emergence rate of Begonia variegata seeds. Background technique [0002] Variety-leaf Begonia, belongs to the Rosaceae and belongs to the Longdong Begonia plant, which is mainly distributed in the southeast edge of the Qinghai-Tibet Plateau. The leaves of this tree species are rich in a variety of nutrients and have the effect of lowering the "three highs". They are the main raw material for making "snow-covered Russian tea" and the main economic tree species in the high mountains and plateaus of western Sichuan. [0003] Begonia variabilis is mainly planted and raised seedlings, published in "Practical Technology of Forestry" (2006, (9): 31-32) "Begonia variegata seedlings and afforestation technology" published in the article "Begonia variabilis seedlings and seedlings technology, this technology reflects Before s...
