Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment:

[0019] This seedling-forming method comprises the following steps:

[0020] (1) Selection of young shoots

[0021] From June to August every year, select a strong high-shrub blueberry tree with vigorous branches, cut off 15-20cm long young shoots at the top of the branches with a cutting tool, remove the leaves at the bottom of the young shoots at 5-10cm, and dip them in the rooting nutrient solution. The nutrient solution formula is WPM medium + 1000ppm IBA + 1000ppm NAA. The pH value of the nutrient solution is between 4.0-5.0. The operating environment temperature for cutting young shoots is between 25-35°C, and the relative humidity is between 80%-100%. Before the tip tool is used, perform local contact high-temperature disinfection on the cutting edge of the scissors. The disinfection temperature is 300°C, and the disinfection time is 15 seconds per contact.

Abstract

The present invention disclose a direct seedling formation method of Vaccinium corymbosum by using young shoot rooting aperture-disk, comprising the following steps of young shoot selection, young shoot cutting and rooting and new seedling transplant. Comparing with traditional branch cuttage seedling raising method, the present invention can advance the rooting time of the Vaccinium corymbosum young shoot from 150 days to 50 days, enhance the rooting rate from 50% to over 80%, enhance the survival rate of the new seedling from 60% to over 90% and reduce the seed rearing period from 12 months to 6 months, and substantially improve the quality of new seedlings.

Description

technical field [0001] The invention relates to a method for raising seedlings of high-shrunk blueberry tender shoots of a rare fruit tree variety, in particular to a method for directly growing seedlings of high-shrub blueberry field tender shoots from rooting plugs. Background technique [0002] The high-bush blueberry fruit contains the most beneficial nutrients, economic value and health care effect among the fruits. It is a precious fruit resource recognized by the world with strong health care functions. It has high economic value and development prospect. In 1998, my country began to conduct in-depth research and development on high-bush blueberries. Due to the weak root system and low absorption capacity of high-shrub blueberries, traditional propagation methods such as seedling grafting, branch cuttings, and conventional group cultivation of seedlings have problems such as slow rooting, low survival rate, poor quality of new seedlings, and long seedling cultivation...
