High-yield method for Ponkan mandarin

Abstract

The invention discloses a high-yield method for Ponkan mandarin. The high-yield method comprises the following steps: firstly, trimming brick wood; secondly, selecting and treating scions; thirdly, grafting; fourthly, carrying out post-grafting management. Branch tips for grafting are soaked into a growth promoting solution prepared from gibberellic acid, a water chestnut peel extract, a citrus bark extract and the balance of water before grafting; after grafting, the branch tips are coated with a wound healing agent prepared from titanium dioxide, a melilotus officinalis alcohol extract, a climbing groundsel herb alcohol extract, an artemisia sieversiana alcohol extract, an anisodus tanguticus alcohol extract, sodium acrylate and konjac glucomannan. The high-yield method for the Ponkan mandarin, disclosed by the invention, has the advantages that crown heights and tree shapes of old fruit trees of the Ponkan mandarin can be improved, and the problem of inner part emptiness of the oldfruit trees of the Ponkan mandarin is effectively solved, so that the fruit quality and yield of the Ponkan mandarin are improved, the output and incomes of the Ponkan mandarin are promoted, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a high-yield method of ponkan. Background technique [0002] Ponkans are generally grown on hillside forests or in bushes. Ponkans have strong adaptability and like a cool and humid environment. They are resistant to cold and high temperature, and can grow between -36 and 43°C. It likes light and can tolerate shade, and is generally distributed in barren hills, sunny slopes, semi-sunny slopes, and valleys, with a slope of 15 to 25 degrees. Drought-tolerant, when there is too much water, the branches and leaves are easy to grow. The soil requirements are not strict, but it grows well in slightly acidic sandy loam with deep soil layer, fertile texture, loose texture and good drainage. [0003] After the age of the ponkan tree is more than 20 years, the crown of the ponkan tree can be as high as 4 to 5 meters, and the leaves of the crown overlap and overlap, which seri...

Problems solved by technology

[0003] After the age of the ponkan tree is more than 20 years, the crown of the ponkan tree can be as high as 4 to 5 meters, and the leaves of the crown overlap and overlap, which seriously shades, the inner hall of the middle and lower layers is empty, the fruiting part moves up, the effective fruiting volume decreases, the management cost increases, and the yield and quality are getting better and better. decline, low economic efficiency
