Problems solved by technology

Malus baccata (L.) Borkh. Also known as Shanjingzi, it has strong cold resistance, luxuriant growth and easy reproduction. It is a commonly used base stock in the breeding of seedlings in apple-producing areas in northern my country. About 10 million apples are produced in Liaoning Province every year. Among the seedlings, more than 95% are rootstocks of Shandingzi. The traditional lamination method of Shandingzi adopts sand storage method, but the temperature and humidity are not easy to control, and the time is long. The effect of stratification treatment, once the seeds germinate quickly in the stratification pit through the body dormancy period, they must be sown in time, otherwise the germination rate will be reduced, it is difficult to control the sowing time, and it will bring a lot of inconvenience to production

Embodiment 1

[0013] The lamination method of T. japonicus is to take mature T. japonicus seeds, soak the clean seeds in warm water at 40°C for 22 hours, then put them into mesh bags, and place them in the shade outdoors for natural freezing for 4-6 days. The natural freezing temperature is from 0 to -5°C, recover the frozen seeds, dry them naturally, and store them in a warehouse without heating. The temperature of the warehouse is -5°C to 5°C, and the relative humidity of the air is below 60%.

[0014] The moisture content of the above-mentioned naturally dried seeds is lower than 10%.

Embodiment 2

[0016] The lamination method of T. japonicus is to take mature T. japonicus seeds, soak the clean seeds in warm water at 45°C for 24 hours, then put them into mesh bags, and place them in the shade outdoors for natural freezing treatment for 6-8 days. The natural freezing temperature is -5 ℃ to -10 ℃, the seeds after freezing treatment are recovered, dried naturally and stored in a warehouse without heating. The temperature of the warehouse is 5 ℃ to 15 ℃.

[0017] The moisture content of the above-mentioned naturally dried seeds is lower than 10%.

Embodiment 3

[0019] The method of lamination of T. chinensis is to take mature T. chinensis seeds, soak the clean seeds in warm water at 50°C for 26 hours, then put them into mesh bags, and place them in the shade outdoors for natural freezing for 8-10 days. The natural freezing temperature is -10°C. ℃ to -15 ℃, recover the frozen seeds, dry them naturally and store them in a warehouse without heating. The temperature of the warehouse is 5 ℃ to 25 ℃, and the relative air humidity is below 60%.

[0020] The moisture content of the above-mentioned naturally dried seeds is lower than 10%.

[0021] The ripe T. chinensis seeds described in embodiment 1, 2 and 3 are preferably prepared by the following method: pluck fully ripe, no damage by disease and insect pests, remove impurities such as pericarp, pulp, fruit stalk, and rinse with clear water , out of the sun, air dry naturally.

[0022] The present invention will be described in further detail below through comparative experiments.

Abstract

The invention discloses a plant cultivating method, in particular to a Malus baccata stratification method, which includes: soaking mature seeds of Malus baccata in warm water at the temperature of from 40 DEG C to 50 DEG C for 22-26 hours; putting the soaked seeds into a mesh bag, and naturally freezing the seeds in the outdoor shade at the freezing temperature of from 0 DEG C to -15 DEG C for 4-10 days; and recovering the frozen seeds, drying in air and storing. The Malus baccata stratification method is simple and quick and reduces production cost. Numerous experiments show that the method is repeatable and stable. The Malus baccata stratification method is easy for temperature and humidity control, short in stratification time and effective in stratification. By the method, the technical problem that the seeds of Malus baccata sprout quickly after dormancy so that failure of timely seeding causes reduction of sprouting percentage is solved. The Malus baccata stratification method is easy for seeding time control and brings great convenience to production.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a lamination method of cassava. Background technique [0002] After the seeds are harvested, they need to undergo a certain low temperature treatment to complete the physiological post-ripening through dormancy and germinate under suitable conditions. In production, the method of sand storage stratification (stratification) is usually used to release the body dormancy of the seeds to improve the emergence rate and neatness. There are certain differences in the low temperature conditions and processing time required for stratification of different seeds. Malus baccata (L.) Borkh. Also known as Shanjingzi, it has strong cold resistance, luxuriant growth and easy reproduction. It is a commonly used base stock in the breeding of seedlings in apple-producing areas in northern my country. About 10 million apples are produced in Liaoning Province every year. Among the seedlings, more t...
