Problems solved by technology

The black rice tree has a long history of application in our country. Whether it is used as food or medicine, it is unique. Every April, in Jiangnan and other places, there is a custom of picking its leaves to cook black rice; the distribution range of the black rice tree Although it is very wide, due to human factors or the impact of bird pests, there has been a lack of effective protection of resources for a long time. The resources of black rice tree have been extremely damaged, the genetic resources have been seriously lost, and the original wild communities in some areas have even disappeared. Therefore, It is imminent to protect the germplasm resources of the black rice tree and carry out the research on the propagation and cultivation of the black rice tree

Embodiment 1

[0013] (1) From the end of October to the first ten days of November in autumn, harvest in time when the fruit of the black rice tree is purple-black; soak the harvested fruit in water for 2 to 3 days until the pulp becomes soft, wash the white seeds with hands and dry them in the shade. spare;

[0014] (2) After adding the prepared seeds to clean fine sand and kneading for 20 minutes, mix the seeds and sand according to the volume ratio seed: wet sand = 1:2. Dilute the wettable powder of fungizolin 800 times, spray and sterilize, and store in sand. First, put the mixed sand seeds in a greenhouse with a temperature of 30°C and a humidity of 80% for 5 days, and then place them in an environment with a temperature of 0-5°C for 50 days. ;

[0015] (3) In the early spring of the next year, sieve the seeds of Azalea from the end of February to the beginning of March, soak the seeds in a solution of 50 mg / L indole acetic acid for 8 hours, rinse them with clean water, and place them...

Abstract

The invention discloses a method for relieving vaccinium bracteatum thunb seeds from dormancy, and belongs to the technical field of plant propagation. The method comprises the following steps: (1), gathering mellow fruits in autumn in time, and modulating to obtain seeds for later use; (2), sterilizing the seeds for sand storage; (3), processing the sand-stored seeds by hormones for accelerating germination in the following spring. According to the invention, after the vaccinium bracteatum thunb seeds are relieved from dormancy, the germination rate of the vaccinium bracteatum thunb seeds reaches above 95.3%.

Description

technical field [0001] The invention relates to a technical method for plant propagation, in particular to a method for releasing the dormancy of the seeds of the black rice tree. Background technique [0002] Vaccinium Bracteatum Thunb., also known as Nanzhu, Dyeshu, etc., is an evergreen shrub or small tree of the Rhododendronaceae Vaccinium genus, widely distributed in southern my country; It is a precious tree species with equal value, and has broad prospects for development and utilization. The black rice tree has a long history of application in our country. Whether it is used as food or medicine, it is unique. Every April, in Jiangnan and other places, there is a custom of picking its leaves to cook black rice; the distribution range of the black rice tree Although it is very wide, due to human factors or the impact of bird pests, there has been a lack of effective protection of resources for a long time. The resources of black rice tree have been extremely damaged, t...
