Embodiment 1

[0010] Embodiment 1, select 5 strains of 4-year-old trees, and carry out topping to main branch extension branch from May 20th to June 5th, that is, when main branch and extension branch grow 6 secondary branches, top is removed, impels all Nutrients are concentrated on the fruit.

[0011] On June 8th, at 25 centimeters from the ground, cut off the bark to the xylem completely with a cutter ring bark, and then cut a line 0.5 centimeters away from the upper knife edge in the same way, and then take out the bark (the width of the strip is 10% of the tree diameter) ).

[0012] June 13th), get 1 gram of gibberellin with 80% content, mix it with 30 grams of alcohol and pour it into 53 liters of water, then add 0.3% urea, and spray it on the tree at 5 o'clock in the afternoon.

[0013] From June 5th to June 15th, every other day from 4:00 p.m. to 5:00 p.m., spray water on the trees with a sprayer (except for rainy and foggy days).

[0014] After implementation, the fruit setting r...

Embodiment 2

[0015] Embodiment 2, choose 5 strains of 6-year-old trees, and remove one jujube head newly issued on the tree from the beginning of spring jujube tree germination to August and remove from the base.

[0016] On June 10th, cut off the bark to the xylem completely with a knife ring bark at 25 cm from the ground, then cut a line 0.7 cm away from the upper knife edge in the same way, and then take out the bark (the width of the strip is 10% of the tree diameter) .

[0017] June 13th), get 1 gram of gibberellin with 80% content, mix it with 30 grams of alcohol and pour it into 53 liters of water, then add 0.3% urea, and spray it on the tree at 5 o'clock in the afternoon.

[0018] From June 5th to June 15th, every other day from 4:00 p.m. to 5:00 p.m., spray water on the trees with a sprayer (except for rainy and foggy days).

[0019] After implementation, the fruit setting rate increased by 30% compared with the same kind.

Abstract

The date fruit bearing technology includes regulating nutrient distribution in date tree through topping in blooming period and girdling in middle blooming period; spraying gibberellin as the plant growth regulator to tree crown in the full blooming stage; and spraying water to tree crown in the middle blooming period. The present invention provides new way for raising yield of date.

Description

technical field [0001] The invention relates to the field of jujube cultivation and management, in particular to a management technique for improving jujube yield. Background technique [0002] At present, in the cultivation and management of jujube trees, there is only a simple water and fertilizer adjustment control on how to increase the yield. The key to affecting the yield of jujube trees is the lack of fruit setting, and there is no mature plan for this. Contents of the invention [0003] In order to solve the problem of low yield of jujube, the invention invents a new technology for increasing the fruit setting of jujube to improve the yield. [0004] The technical solution adopted in the present invention is a jujube fruit-setting technology, which is special in that it regulates its own nutrient distribution, that is, topping at the flowering stage and girdling at the middle stage of flowering; Spray gibberellin; humidify the tree, that is, spray water on the cro...
