Embodiment

[0013] In the fourth year of fruiting, properly adjust the amount of remaining fruit and the ratio of the front, middle and back of the fruiting part to 1:3:1, and gradually advance to the base of the branch group. Branches mainly reduce the amount of fruit remaining, and stimulate the base of the branch group to pump out the vegetative branches on the back and the vegetative branches of the fruit moss on the back.

[0014] For the vegetative branches on the back or the branches with fruit moss on the back that have germinated at the base of the old branch group for more than 3 years, leave a healthy and disease-free paper strip as the training object, and remove the rest. Five technical measures to cultivate a new uniaxial extension fruiting branch group year by year. If there is no vegetative branch on the back of the over-aging branch group, you can choose a strong fruit moss branch on the back of the base to remove flower buds or young fruits to promote its fruiting. Moss ...

Abstract

The invention belongs to the technical field of crop cultivation, and in particular relates to a novel red Fuji apple uniaxial extension fruit-bearing branch group updating technology. The technology comprises the following steps of: frequently removing branches but never cutting off the branch group to reduce fruit quantity and make fruits grow upwards; cultivating a new branch group; girdling, ringing, exciting and pinching a dorsal vegetative shoot at proper time; and retracting and updating at the right time. The technology has the advantages that: a new dorsal vegetative shoot is re-cultivated on the substrate of the uniaxial extension fruit-bearing branch group, and after the branch is cultivated into a new uniaxial extension fruit-bearing branch group, the branch is retracted at the right time to complete updating, so that the fruit-bearing branch can still be rejuvenated after a high quality period to ensure the permanency and high yield stability of the fruit-bearing branch group.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a new technology for renewing fruiting branches of red Fuji apples by uniaxial extension. Background technique [0002] As the main fresh-eating and storage-resistant variety in my country, Red Fuji apple has become the main apple variety. With the growing area of ​​cultivation, various provinces and municipalities have successively issued management regulations and key technical points for Red Fuji apples, but most of them are limited to the cultivation of tree shape and branch groups. As a result, the pruning and renewal and rejuvenation techniques of branch groups are not meticulous. , Unscientific, and even lead to excessive aging, bloated, poor ventilation and light transmission of fruiting branches, and repeated pruning patterns of old varieties such as Xiao Guoguang and Red Banana, which seriously affected the quality and economic benefits of Red Fuji ...
