White pomelo high-yield method

Abstract

The invention belongs to the technical field of white pomelo planting, and discloses a white pomelo high-yield method. The method comprises the following steps: the self-flowering and non-fruiting mechanism of Dianjiang white pomelo is tested; a pollination yield increasing technology of girdling, flower promoting agent, artificial cross pollination and nutritional fruit retention is provided; the winter fruit falling and granulating mechanism of Dianjiang late pomelo is ascertained, the winter anti-falling and anti-granulating comprehensive technology of Dianjiang late pomelo with balanced fertilization, hormone fruit retention, flood drainage and film mulching and planting in proper land is formed, and a 3 + 2 + organic + medium-micro nutrition diagnosis formula fertilization technology is provided; simple pruning technologies of low-yield tree rotation fruiting, branch break without tree break, old tree crown retraction, root cutting and updating, upper opening, lower hanging branch beating, peripheral thinning and dense and crossed removal, and inner withered branch pruning of production trees are adopted; a green mite prevention and control technology of tree trunk whitening, predatory mites, vegetable oil and matrine for mites is established. According to the method, a high-quality and high-yield technical system of characteristic Dianjiang white pomelo is formed, and scientific and effective technical support is continuously provided for healthy development of the industry.

Description

technical field [0001] The invention belongs to the technical field of white pomelo planting, and in particular relates to a method for increasing the yield of white pomelo. Background technique [0002] Chongqing pomelo has a long history of cultivation, and local germplasm resources are abundant. It has been recorded in "Shan Hai Jing" and "Shang Shu". Dianjiang white pomelo is one of Chongqing's "five famous pomelo". It has been praised by the leaders of the party and the state, and has its own unique characteristics: the tree is tall, vigorous, and the crown is mostly natural round; The characteristics are not found in other Dianjiang pomelo. [0003] Dianjiang white pomelo has made an important contribution to the development of Dianjiang's agricultural industry and the increase of farmers' income. However, after the 1990s, with the large-scale planting of Dianjiang white pomelo, the pollination varieties were messy, resulting in different appearance and quality of Dia...

Problems solved by technology

[0003] Dianjiang white pomelo has made an important contribution to the development of Dianjiang's agricultural industry and the increase of farmers' income. However, after the 1990s, with the large-scale planting of Dianjiang white pomelo, the pollination varieties were messy, resulting in different appearance and quality of Dianjiang white pomelo

And in the long-term production development, there have been tree aging, variety degradation, and low yield and low efficiency caused by false self-flowering, which seriously restricts the improvement of the yield, quality and production efficiency of Dianjiang white pomelo, and also constitutes a serious obstacle to the sustainable development of the industry.

[0004] Through the above analysis, the existing problems and defects of the prior art are as follows: after the 1990s, with the large-scale planting of Dianjiang white pomelo, the pollination varieties were confused, resulting in different appearance and quality of Dianjiang white pomelo; the tree body was aging and the variety was degraded; The worldwide problem of low quantity and low output
