Problems solved by technology

In addition, the germinated Fujian mountain cherry seeds are susceptible to uneven seedling emergence due to the influence of external factors, which in turn leads to serious growth and differentiation of seedlings during the seedling raising process.
At present, public reports break the dormancy of Fujian mountain cherry seeds and the main methods of sowing seedlings are: sowing with harvesting, refrigerated autumn sowing, refrigerated spring sowing, variable temperature sand storage for autumn sowing, variable temperature sand storage for spring sowing, air-dried autumn sowing, air-dried spring sowing, and sand storage There are multiple methods such as autumn sowing, sand storage and spring sowing, but the germination rate of the methods of air-drying autumn

Embodiment 1

[0023] A method for breaking dormancy and bud cultivation of Fujian mountain cherry seeds in a balanced manner, comprising the following steps:

[0024] Step 1: Seed collection and processing

[0025] From the end of April to the first ten days of May every year, collect the fully mature Fujian mountain cherry fruit whose peel has changed from greenish yellow to bright red, remove the peel and pulp, rinse with clean water to remove impurities and undeveloped seeds, wash and dry in the shade; if not used temporarily, use Store in plastic bags at a temperature of 3-5°C for later use;

[0026] Step 2: Seed disinfection and drying

[0027] Soak the seeds in the previous step with 0.3% potassium permanganate solution for 60 minutes, then wash them with water until they are colorless; place the seeds evenly in the sun at 20-30°C from 10:00 am to 3:00 pm on a sunny day For 40 minutes, when the tip of the hard seed coat is slightly cracked, the tip of the hard seed coat is put away,...

Abstract

The invention discloses a balance dormancy breaking and seedling cultivation method of cerasus campanulata seeds. The method comprises the following steps: collecting and treating the seeds, namely, soaking the seeds in a 0.3% potassium permanganate solution for 60 minutes, and then washing the seeds with water until the seeds are colorless; evenly spreading out the seeds under the sun at the temperature of 20-30 DEG C from 10 A.M. to 3 P.M. in a sunny day, exposing to the sun for 40-60 minutes, putting away the seeds when the longitudinal seam apex acuminate of hard seed coat has tiny crack, and then treating by accelerating germination; breaking dormancy and accelerating germination, namely, fully mixing the seeds with washed river sand having the water content of 18-25% according to the ratio of 1: (3-4), then putting the mixture into a basket or a bag, and storing in an air-conditioning fruit and vegetable fresh-keeping refrigeration house having the temperature of 2-5 DEG C and the relative humidity of 90-95% for 70-80 days; carrying out seedling cultivation. The method for breaking dormancy as well as culturing and transplanting seedlings of the cerasus campanulata seeds is capable of remarkably improving the germination rate and the emergence rate, thus being suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and relates to a seedling breeding technology of rare woody flower Fukienza cherry, in particular to a method for balanced dormancy breaking and bud cultivation of Fukienza cherry seeds. Background technique [0002] Fujian Mountain Cherry Blossom (Prunus campanulata Maxim), a deciduous tree belonging to Rosaceae, is widely distributed in Fujian, Zhejiang, Guangdong, Guangxi, Taiwan and other provinces and regions. , flowers first and then leaves, the trees are full of flowers, charming and colorful, and it is magnificent.
