High-irrigation blueberry field young-shoot rooting plug-seeding direct seedling method

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...
