Method for planting red jujubes in alpine region

Abstract

The invention discloses a method for planting red jujubes, and particularly relates to a method for planting the red jujubes in the north alpine region. The aim of building a direct-seeding red jujube garden is achieved mainly through sowing and seedling raising of tree stacks, variety choice and field management of grafting, grafting of jujube trees, and field management and overwintering management of nursery stocks. According to the method for planting the red jujubes, red jujube industrialization production can be achieved in the north alpine region like Sinkiang and northern Sinkiang regions, in the grafting year, people can harvest the fresh red jujubes of 150-250 kg / mu and obtain a large number of high-quality grafting nursery stocks, the red jujube industry can be developed in a large-scale mode, the north alpine region where the red jujubes can not be planted can also conduct planting, and the method is rapid in effect and high in yield. Particularly, sunlight in the north alpine region is abundant in summer, the temperature difference between day and night is large so as to be beneficial to accumulating carbohydrate, and therefore the produced red jujubes are good in quality and high in yield.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to planting jujubes, in particular to a method for planting jujubes in northern alpine regions. technical background [0002] Date tree (Ziziphus ju juba Mill) belongs to the Rhamnaceae jujube plant, which has a long history of cultivation in my country and is the main economic tree species planted in many places. [0003] Jujube is rich in nutrition, not only can be eaten fresh, but also can be dried and processed, and it is also a good health-care medicinal food. Due to its high economic value and broad domestic and foreign sales markets, it has been introduced to Japan, North Korea, the United States, the Philippines, India, Thailand and other places. It is a popular tree species. [0004] However, the cultivation of jujube trees is limited by geography and climate. In particular, the absolute minimum temperature in winter must not be lower than -23°C. Fo...

AI Technical Summary

Problems solved by technology

[0004] However, the cultivation of jujube trees is limited by geography and climate. In particular, the absolute minimum temperature in winter must not be lower than -23°C. For example, in the vast alpine regions of northern Xinjiang, the low temperature of -30 to -40°C often occurs in winter, and there has been no planting in history. The records of jujube trees, especially in the history of Chinese cultivation, have never crossed the 43° north latitude line
