Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The invention provides a Yuhuan pomelo high-yield crown cultivation and pruning method, which is specifically implemented according to the following steps:

[0020] Step 1, 0-6 years: Cultivate the backbone tree shape, divided into two steps, the first step: in the 1-3 years, after the saplings are planted, they will be fixed at a distance of 50 cm from the ground, and the trunk height will be kept at 30 cm after budding in spring - 40 cm, all buds below 30 cm - 40 cm are wiped out, and 3 - 4 side buds in different directions that grow robustly above 30 cm - 40 cm are reserved to configure 3 to 4 main branches. Leave one bud at an interval of 30 cm, leave 3 to 5 side buds in different positions, and erase the rest of the buds to configure 3 to 5 sub-main branches; arrange side branches evenly on each main branch and sub-main branch 5-...

Abstract

The invention discloses a citrus grandis high yield crown cultivating and trimming method. The high yield crown cultivating and trimming method is specifically implemented according to the following steps: cultivating and trimming 0-6-year citrus grandis high yield young treelets, and cultivating backbone tree forms; cultivating and trimming citrus grandis adult trees which are more than 6 years to cultivate high-yield high-quality crowns. The citrus grandis high yield tree obtained by trimming with the method has the advantages that yield is improved by 25%, the high-quality premium fruit rate is improved by 30%, and the fruit breaking rate is lowered by 15%, and the citrus grandis high yield tree has the advantages of even fruit size, fine fruit surface oil bubble, thin, smooth and glossy fruit peel and better condition.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating and pruning a high-yield tree crown of Yuhuan pomelo. Background technique [0002] Yuhuan pomelo, also known as Chumen Wendan, is an excellent variety of pomelo in the Rutaceae citrus genus. Originally produced in Xidong, Longtai County, Zhangzhou, Fujian Province, it has been cultivated in Yuhuan for more than 130 years. After cultivation and selection, Yuhuan pomelo has become well-known both at home and abroad, and has become a rising star of pomelo. However, the pruning of Yuhuan pomelo has always been imitating the pruning method of citrus. It mainly keeps the autumn shoots and bears fruit, and does not leave the inner chamber branches. The canopy becomes more dense. The resulting yield is low, the result part moves outward, the fruit has rough skin and large fruit, the cracked fruit is heavy, and the quality is poor. Conte...
