The shape of slender pine-cone apple tree and its pruning method

Abstract

The invention discloses an elongated pinecone apple tree form and a trimming method thereof; the integral tree form is in an elongated pinecone shape; the tree is 3.5-4.5m in height when approaching a full bearing period, and has 25-30 main branches; the tree is 2.8-3m after lowering the cap, the main trunk is 1.0-1.5 m in height, the tree has 18-22 main branches, a main branch opening angle is 110-130 degrees, the main branch is 50-70cm in length on the upper portion of the crown, and 110-130cm on the lower portion of the crown; the spacing between the main branches is 10-20cm; the main branches are arranged in a spiral manner around the main trunk; the branch-trunk ratio is 1:3-6; the branch group-main branch ratio is 1:5-7. The tree form is small on top and big in bottom, tidy and standard, strong in main trunk, strong in wind-resistance, ventilating and light transmission, suitable for close planting, and is a high yield, stable yield, high-quality and high efficiency tree form; the trimming method complies with the trend that tree body frame decreases and trimming is simplified; the method is easy to handle, and good for promotion in wind-line close planting apple gardens.

Description

technical field [0001] The invention belongs to the technical field of shaping and pruning of apple trees, in particular to a slender pine-cone-shaped apple tree shape and a pruning method thereof. Background technique [0002] The plastic pruning of apple trees is an important measure to cultivate high-yield and stable-yield tree shapes and to regulate the relationship between growth and fruit. Its main functions are: build a good tree skeleton, improve ventilation and light transmission conditions, increase the utilization rate of light energy, cultivate fruiting branches and branch groups, and promote fruiting; establish a relatively balanced relationship between growth and fruiting, and alleviate the relationship between aging and renewal. The contradictions; so as to achieve the purpose of increasing the yield per unit area, improving the quality of fruit, and increasing economic benefits. [0003] At present, orchards with wide rows and dense planting are the producti...

Problems solved by technology

The high-yield tree shapes that have been popularized in recent years mainly include small-crown sparse-layered, spindle-shaped, and pine-cone-shaped trees. These tree shapes are technically difficult, time-consuming and labor-intensive to shape, the trunk is not strong, not suitable for dense planting, and high and stable yields are not good. and other shortcomings
