Problems solved by technology

The traditional propagation methods of Junzao mainly include root tiller seedlings and grafted seedlings. Their disadvantages are that they require a lot of propagation materials, have a low reproduction coefficient, cannot be produced every year, and are easy to spread viruses.
Due to the large demand for jujube seedlings, the quality requirements for jujube seedlings are not strict. In many places, there are mixed varieties, serious pests and diseases, and even the possibility of introducing destructive jujube mad seedlings in jujube gardens, resulting in poor quality of jujube. , low yield, low survival rate of long-distance transportation and other unfavorable factors exist

Abstract

The invention relates to an agricultural breeding technology and especially relates to a Xinjiang Jun date industrial-seedling virus-free tissue culture rapid-propagation technology. The Xinjiang Jun date virus-free tissue culture rapid-propagation technology mainly comprises the following steps of 1, Jun date tree stem explant rapid-starting, 2, Jun date shoot tip virus-free culture, 3, Jun date virus-free tissue culture seedling propagation and 4, Jun date virus-free tissue culture seedling rooting culture. The Xinjiang Jun date industrial-seedling virus-free tissue culture rapid-propagation technology has a reasonable technology, can be operated simply, is suitable for industrial seedling growing, greatly improves a survival rate, effectively prevents jujube witches' broom disease and is economic and practical.

Description

technical field [0001] The invention relates to agricultural breeding technology, in particular to a technology for virus-free tissue culture and rapid propagation of jujube jujube industrialized seedlings in Xinjiang. Background technique [0002] Xinjiang has a vast territory, abundant water, soil, light and heat resources, and a large temperature difference between day and night. It has unique natural conditions for the development of jujube industry. Jun jujube has high sugar content, high dry matter accumulation, high quality, best-selling fruit, and rising prices. Planting jujube trees has become an important way for Xinjiang's workers and workers to get rich. [0003] Junzao is originally produced in Shanxi, and is now one of the main varieties in Nanjiang and the 14th Division. This variety has strong adaptability, high and stable yield. Large fruit, suitable for drying, good quality, durable for storage and transportation. The traditional propagation methods of Ju...
