Fruit mulberry tree shape pruning method

Abstract

The invention discloses a fruit mulberry tree shape pruning method, and belongs to the technical field of fruit mulberry cultivation. The fruit mulberry tree shape pruning method comprises the following steps of before fruit mulberry saplings grow to the height of 120 cm, reserving no lateral branches, and when the fruit mulberry saplings grow to the height of 120 cm, cutting the saplings at the height of 100 cm to form primary branches; reserving the uppermost four buds for the primary branches as main branches and cutting top buds for the main branches; fixing the primary branches; using a rope to transversely pull the main branches in four directions respectively, and when the main branches are essentially shaped, removing the rope, wherein the main branches are distributed in a cross shape to form secondary branches; reserving 5-7 upward growing lateral buds for each secondary branch and leaving the length of 20 cm for the lateral branches to form tertiary branches; reserving 2 upward growing buds for all the tertiary branches as quaternary branches, wherein the quaternary branches are fruit-bearing parent branches. According to fruit mulberry trees, the branches are uniformlyscattered, the ventilation and light transmittance are good, and diseases and insect pests are reduced; branches and leaves receive sufficient illumination, the photosynthesis is good, and the fruit sugar degree is high; the trees have many branches, and the yield is high. Besides, the trees are short, the branches are short, and fruits are convenient to pick.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit and mulberry cultivation, in particular to a method for trimming fruit and mulberry trees. 【Background technique】 [0002] Fruit mulberry is a fruit-based mulberry variety. Its mature fruit is also called mulberry and mulberry jujube, which is rich in nutrients and is a rare nutritional and health-care fruit. The type of mulberry tree has a direct impact on fruit yield and quality. In the prior art, the fruit mulberry tree type is allowed to be generated freely or the fruit mulberry tree type is trimmed due to the lack of scientific planning. The existing tree type trimming method is more complicated, the forming is slow, the tree body is tall, it is inconvenient to manage and pick the fruit, and it is easy to produce fruit drop. 【Content of invention】 [0003] Aiming at the above existing problems, the present invention discloses a method for trimming the shape of a fruit mulberry tree, aimi...
