Novel method for cultivating seedlings of Shanzao jujube

Abstract

The invention relates to a novel method for cultivating seedlings of Shanzao jujube. According to the method, a mother plant is dug off from a healthy and vigorous wild jujube tree, a side root which is healthy and vigorous in soil is found, a high-quality wild jujube scion is connected to the side root by means of grafting first, a high-quality red jujube scion is connected to the high-quality wild jujube scion also by means of grafting, two graft parts are tightly wrapped with plastic tapes to ensure air tightness and water tightness, the grafted side root is spread and pressed and buried with fertile soil by being 45 degrees angled to the land, the tip of each scion is 2cm off the land, fertilizer and water are applied once at the position 40cm away from the side root, a plurality of buds grow from the scions out of the land after one month, the buds, expect ones at the top end, are removed by shearing, the in-soil parts of the scions grow roots on about Tomb-sweeping Day of a third year, the soil around the scions are removed, the graft parts of the scions are cut off, the scions are then transplanted in a jujube orchard, and a high-quality novel variety of Shanzao jujube is obtained.

Description

1. Technical field [0001] The invention belongs to a method for cultivating tree species, in particular to a new method for cultivating jujube seedlings. 2. Background technology [0002] Jujube is one of the important tree species native to my country. It has the characteristics of resistance to salt and alkali, barrenness, drought and rain. Therefore, jujube not only has important economic value, but also a pioneer tree species for greening barren hills and improving the ecological environment. In many areas, especially in mountainous areas, the development of jujube trees has become a pillar industry in rural areas, playing an important role in helping farmers get rid of poverty and become well-off and achieve sustainable rural development. At present, the development of excellent jujube varieties is mainly achieved by split grafting, skin grafting, laparotomy, and budding. Using these methods, the grafting method is simple, the water loss at the interface is large, the ...

Problems solved by technology

At present, the development of excellent jujube varieties is mainly achieved by split grafting, skin grafting, laparotomy, and budding. Using these methods, the grafting method is simple, the water loss at the interface is large, the healing time is short, the survival rate is low, and the variety is degraded. Seriously, new fine varieties cannot be born
