Grafting propagation method of hybrid citrus

Abstract

The invention provides a grafting propagation method of hybrid citrus. The grafting propagation method of hybrid citrus has the beneficial effects that the factory production effect is realized, the grafting time is long, the growth speed is quick, the growth is vigorous, and the quality of seeds and seedlings are high; the method is simple, convenient and practical, and the survival rate of the seeds and seedlings can reach 95% or above; compared with an exposed cultivation grafting method, the survival rate can be increased by 10% or above.

Description

Technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for grafting and breeding hybrid citrus. Background technique [0002] Citrus is one of the four major fruit trees in the city. The highest peak once reached about 100,000 mu. The single species is dominated by Wenzhou mandarin, which currently has about 80,000 mu. In recent years, the production of mandarin-based mandarins in the suburbs of Shanghai has been greatly impacted. Many villages and towns produce low-quality fruits, with low output value and low profits, which has destroyed a large number of orange orchards and replaced them with other crops. In view of this, the unit introduced more than 10 new hybrid citrus cultivars (referred to as Zakan) three years ago, which were bred by the cross between citrus and orange. Planting observation and cultivation research were carried out in the multi-span plastic greenhouse. In 2018, two new varieties, Ehime 28 (tr...

Problems solved by technology

The prerequisite for developing miscellaneous citrus production is to have high-quality grafted seedlings. However, citrus was originally grafted in the open field. The survival rate is low, the seedlings grow slowly and the quality is not high, which directly affects the production of citrus fruit trees.
