Problems solved by technology

However, the traditional method of opening the nails of winter jujube is carried out on the trunk of winter jujube. This method can have a direct impact on the entire tree of winter jujube. For example, if the nail mouth is too heavy or too wide, it will affect...

Embodiment 1

[0037] The method of high position and multi-point opening of winter jujube tree:

[0038] On a 6-year-old winter jujube tree that has entered the fruiting stage, select 5 vigorous main branches for multi-point cutting. The cutting part is selected at the 15 cm smooth place at the base, and at the same time, this tree leaves 2 main branches. Branches are not to be armored; the branches and branches of the armor are not overlapped, and the azimuth jacks are staggered; 10ppm gibberellin is sprayed once on the whole tree body 3 days after the armor is opened; 0.1% borax is added at the same time when spraying; Apply 50% phoxim solution to the nail opening 5 days after nail opening, apply once every 5 days, and apply it 3 times in a row, then protect the nail opening with plastic to promote nail opening healing; see figure 1 .

Embodiment 2

[0040] The experimental garden is located in the 15-acre winter jujube garden of South Korea Shifeng's family in Jinzhuangzi Village, Dafengdui Town, Jinghai County. The garden was planted with golden silk jujube in March 1999, and grafted with winter jujube in late April of that year. 2X4 meters, 83 plants per mu, surveyed in March 2003, the average trunk height is 65 cm, the trunk circumference is 15.3 cm, the crown diameter is 1.8X1.7 meters, the tree shape is a layered shape of small crowns, and there are 5-7 main branches, 2003 In 2004, the plant yielded 0.5 kg, and the yield per mu was 83 catties. Based on the unit price of 10 yuan / catties, the output value per mu was 830 yuan; The width of the first plant is 0.5 cm. The average plant yield of the year increased to 6.2 catties, the average yield per mu was 514.6 catties, and the output value per mu was 5146 yuan.

[0041] From 2005 to 2006, we began to undertake the project of "Promotion of High-quality and High-yield C...

Embodiment 3

[0043] Ma Guangcheng’s winter jujube orchard in Zhangjia Village, Wangkou Town, Jinghai County covers an area of ​​50 mu, and 83 trees are planted per mu. The tree is 11 years old and is a large tree in the full fruit period. It has been using this method since 2007. The branches are opened, and 2-3 branches are left without opening. The width of the opening is 0.8 cm, and the widest is no more than 1.0 cm. Before germination, the garden applied 0.6 catties of special fertilizer for fruit trees per plant, 2 catties of special fertilizer for fruit trees on July 13 after opening, and 2 kg of special fertilizer for fruit trees on August 15. The survey results on October 8, 2009: the plant yield was 27.3 catties, and the yield per mu was 2265.9 catties. Based on the current market price of 6 yuan / catties, the yield value per mu was 13,595 yuan. However, the plant yield was 18.8 jin by the traditional method of opening the carapace, and the yield per mu was 1560.4 jin. Calculated a...

Abstract

The invention discloses a high-position multi-point debarking method of a winter jujube tree, which is characterized in that the 3-5 vigorous main branches or the vigorous large fruit branches and the central trunk of the winter jujube tree which grows for 3-12 years are selected and debarked at multiple points, the debarking positions are at smooth positions which are 10-30cm far away from the stem base growing point of the winter jujube tree, 1-3 main branches per tree are not debarked to foster a tree body, nourish roots and strengthen the tree, and the problem that the tree dies because the trunk is improperly debarked can be effectively prevented. The width of each debarked opening is 0.8-1.0cm and 10-15ppm gibberellin is sprayed for 1-2 times within 1-7 days after debarking. The method disclosed by the invention has the advantages that the crown is formed rapidly, the tree can step into a fruiting period very rapidly after debarking, the tree body growth well, the tree is vigorous, the disease resistance is strong, the yield is increased very rapidly, the tree can step into a full fruiting period, the average yield per mu can reach 1250kg, the production value per mu is more than 1.5 times higher than the production value per mu of the traditional method and the benefit is very remarkable. At present, the application area in our county is more than 40 thousand mu. In consideration of the remarkable effectiveness of the method, we are energetically popularizing and applying the method.

Description

technical field [0001] The invention belongs to the technical field of agricultural trees, and relates to a "high-position, multi-point" method for opening the nails of winter jujube trees. Background technique [0002] Winter jujube is a variety with excellent comprehensive quality among the fresh edible jujube varieties. The planting area has been expanding rapidly in the past ten years, but it is difficult for young winter jujube trees to bear fruit, the time for fruiting is long, and the fruit setting rate of mature winter jujube trees is low. The problem of low yield is becoming more and more prominent. According to our long-term production practice and management experience, we believe that "opening" winter jujube trees is an effective way to solve these problems. Jujube tree peeling is to peel the jujube tree in a ring. After cutting off the phloem of the trunk, the nutrients produced by the leaves are suspended, which is conducive to flowering and fruit setting, inc...
