Embodiment 1

[0029] 1. Cultivation of cutting mother plants: Soak the imported tomato seeds in room temperature water for 10 minutes, remove them and stir them in water at 50-55°C, keep the water temperature for 15-30 minutes, remove the seeds and put them in cold water to dissipate the residual heat , then soak at room temperature for 4-5 hours, wrap the seeds with gauze, and accelerate germination in a 30°C incubator. All sprouted. Sow the germinated seeds in a 50-hole hole tray, in which the seedling substrate is a mixture of peat: vermiculite: perlite = 1:1:1, with a moisture content of about 70% (that is, it can be formed into a ball by hand, without obvious dripping water), seedling raising facilities The temperature is controlled at 28-30°C during the day and 18-20°C at night, the air humidity is controlled above 80% before emergence, and the light is weak (3000-20000lx); when the cotyledons unfold and the true leaves begin to grow, the light gradually returns to normal (20000-20000...

Abstract

The invention discloses a rapid propagation method for high-quality solanum lycopersicum seedlings. The method comprises the following steps: firstly, cultivating a cutting mother plant; preparing fortaking buds for cuttage when the seedling shows the first inflorescence; collecting a cutting at the position of 0.6-0.8 cm above the section of the first lateral bud, dividing the seedling into a terminal bud cutting seedling, a middle lateral bud cutting seedling and a root lateral bud cutting seedling, and performing cuttage cultivation to regenerate seedlings after classified collection. According to the method, the solanum lycopersicum seedling in the bud stage is cut into branches for lateral bud regeneration, multiple seedlings can be achieved with one seed, and the seedling cost can be directly reduced; and the emergence rate and the strong seedling rate of the regenerated seedlings are both higher than 95%. The method can be applied to industrial seedling raising practice of thesolanum lycopersicum seedlings.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a seedling production method that can be applied to rapid and high-quality multiplication of tomato seedlings with high quality and high price. Background technique [0002] Tomato (Solanum lycopersicum L.) is an annual or perennial plant belonging to the family Solanaceae. Grass This plant , originated in the Andes region of South America, is a warm-loving vegetable. my country has a record of cultivation as an ornamental crop in the Qing Dynasty. It began to be cultivated and eaten as a vegetable in the suburban areas in the early 20th century. After entering the 1950s, it developed rapidly and gradually became the vegetable with the largest output in my country, with an annual output of about 55 million tons. About 7% of the total. [0003] Due to the relatively short history of tomato cultivation in my country, the work related to tomato breeding started relatively l...
