High-yield high-stress resistance breeding method for Chinese torreya

Abstract

The invention belongs to the technical field of seed breeding and in particular discloses a high-yield high-stress resistance breeding method for Chinese torreya. The method comprises the following steps: (1) carrying out primary cleaning, namely cleaning picked seeds in clean water, removing stain, and fishing up; (2) draining off the water naturally, namely spreading the seeds after primary cleaning in the step (1) on a mesh screen, and draining off the water naturally; (3) screening the seeds, namely screening seeds which are full and strong in grain by using a seed screening device, and grading the seeds; (4) carrying out sterilization, namely soaking the seeds screened in the step (3) into a disinfectant for 30-60 minutes; (5) drying, namely drying the seeds sterilized in the step (4)at a preheated place for 6-8 hours in the air; (6) collecting, namely naturally cooling the dried seeds naturally, and collecting and putting into bags. The seeds selected according to the scheme areall full in grain and healthy and vigorous, and the yield and the stress resistance of the seeds can be improved through sterilization and drying.

Description

technical field [0001] The invention belongs to the technical field of seed breeding, and in particular relates to a high-yield and high-stress-resistance breeding method for Chinese torreya seeds. Background technique [0002] Torreya torreya, also known as Chinese torreya, is an evergreen tree belonging to Taxaceae, Taxaceae, and Torreya genus. It is a native tree species in China and a rare economic tree species in the world. It mainly grows in relatively humid areas in southern China and is born at an altitude of 1400 meters. Below, warm and rainy, yellow soil, red soil, yellow brown soil area. Torreya can reach a height of 25m. It is a kind of Torreya tree, usually obtained by grafting. Torreya torreya grows and matures for three years: it blooms in the first year, bears fruit in the second year, and matures in the third year. The fruit of Torreya torreya is a nut with high nutritional value. The dried fruit is called "torreya", which is a famous dried fruit. It is ol...
