Problems solved by technology

Although the grafted Junzao has obvious advantages compared with the local jujubes, the grafted Junzao in the whole county has not yet exerted greater benefits due to mixed varieties, low grafting technology and inadequate daily management measures.

Embodiment 1

[0023] Embodiment 1, a method for improving low-yield aging jujube orchard in sandy land, is characterized in that the specific steps are:

[0024] a. Grafting of old jujube trees: In the Jingtai area of ​​Gansu, in early May, when the temperature rises and stabilizes above 5°C, grafting is carried out when the tree body is active; Gansu Xiaokou jujube, which has grown for more than 5 years, is a mixed variety. The old jujube tree is used as the rootstock, and the dwarf variety scion suitable for local dense planting is used for grafting improvement;

[0025] b. Replanting jujube: while grafting the old jujube trees in the jujube orchard, plant jujube kernels with full seeds and no damage in the middle of the old jujube trees, 5 seeds per hole, planting depth 2cm, after the jujube seedlings emerge and the seedlings, every The hole holds 1 sapling;

[0026] c. Zizyphus jujube grafting: after the jujube grows for one year, grafting is carried out in the second year, with jujube...

Abstract

The invention relates to a method for improving a low-yield aged jujube yard in sandy land. The method is characterized by comprising specific steps: a, grafting aged jujube trees; b, replanting wild jujubes; c, grafting the wild jujubes; d, performing branch management after grafting; e, and planting high-stem plants. Started with breed improvement, jun jujubes in good stock are introduced to graft and transform an aged orchard, a dwarf and close planting technology is applied, bud picking and trimming are more convenient, and management cost is reduced. The method reduces labor intensity, improves yield and quality, and effectively improves planting level of Chinese-date, and achieves objectives of increasing agricultural efficiency and farmer's income.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a method for improving low-yield and aging jujube orchards in desertified land. Background technique [0002] The jujube tree is a unique jujube tree native to my country. It has been cultivated for more than 3,000 years. During the long-term cultivation and training process, the jujube tree has produced a large number of variations. Due to the influence of many factors such as natural hybrid gene mutation and the coexistence of multiple breeding methods, the same variety has great differences, showing great differences in growth and fruiting. In recent years, domestic scientific research institutes have taken active measures to develop China's jujube industry, invested a lot of manpower, material and financial resources to rapidly improve the development level of my country's jujube industry, and have developed a large number of high-quality jujube varieties. The Shanxi A...
