Problems solved by technology

At present, the shape of jujube trees in China is generally thin-layered and round-headed, and the tree body is relatively large. It is necessary to climb up the tree when harvesting by hand, and most of the branches of jujube trees have thorns, and people are often injured during the picking process. Therefore, the picking of fresh jujubes has become a difficult problem in the production of fresh jujubes in my country; in addition, due to the tall trees, it is difficult to control pests and diseases. harm

Embodiment Construction

[0033] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0034] The tree shape design of the dwarf-shaped jujube tree involved in the present invention is: the dwarf-shaped tree shape is set as dry height 50cm, has 1 central trunk, 2-3 layers of main branches, and every layer is attached to 2 main branches, 2 The main branch extends forward in the opposite direction. The angle between the main branch and the central trunk is about 80 degrees. There are several fruiting branch groups in the space on both sides of the main branch. The fruiting branch groups are perpendicular to the row direction, and The included angle with the central trunk is 70-80 degrees, and the length of the fruiting branches is 50-60cm. The principle is that it is roughly the same as the length of a human arm. The height of th...

Abstract

The invention relates to a pruning method of a short wall shaped jujube tree, which comprises the following steps of: (1) planting the pruning of current year: (a) planting the winter pruning of current year; and (b) planting the summer pruning of current year; (2) planting the pruning of next year: (a) planting the winter pruning of next year; and (b) planting the summer pruning of next year; (3) planting the pruning of third year: (a) planting the winter pruning of the third year; and (b) planting the summer pruning of the third year; thus, completing the pruning of the short wall shaped jujube tree of the third year. The invention resolves the problems in aspects of difficult picking and inconvenient prevention and control operation of plant diseases and insect pests and the like in fresh edible jujube cultivation, improves the artificial picking efficiency and prevention and control effect of plant diseases and insect pests of fresh edible jujubes, and facilitates the development of fresh edible jujubes in China.

Description

technical field [0001] The invention belongs to the field of agriculture and horticulture, in particular to a method for shaping and pruning dwarf-shaped jujube trees. Background technique [0002] Jujube is native to my country and has a long history of cultivation, more than 4,000 years ago. It is a unique economic tree species in my country. At present, the cultivated area of ​​jujube trees in my country has reached more than 20 million mu, and the total annual output has reached 2 million tons. The cultivated area and output of jujube trees in my country account for more than 98% of the world's total output. The jujube fruits used by countries in the world are all supplied by my country. [0003] Jujube fruit is rich in nutrition, especially fresh jujube contains very high vitamin C. It is determined that every 100 grams of fresh jujube contains 200-800 mg of vitamin C, which is 5-20 times that of apples, so it is known as "live vitamin pill"; Jujube also contains cycli...
