A kind of rootstock construction method of apple tree with early fruit and high yield

Abstract

The invention discloses a method for building an apple tree rootstock with early fruit and high yield, comprising the steps of: 1) planting and building: planting Xinjiang wild apple seedlings in spring to build a garden; 2) high grafting in autumn: after planting in the autumn of the current year, selecting good apple varieties Scion is carried out with woody bud grafting at described Xinjiang wild apple sapling 60-70cm place apart from ground; 3) spring pruning: before planting second year spring bud, pruning at 0.5cm place above described grafting bud, allows grafting bud to germinate Pull out the branches, and wipe off the remaining germinated branches at the lower part, and pull some branches in summer; 4) pull the thin tubes: pull the branches to promote flowers in the third year after planting; 5) guarantee high yield: pull the branches year after year from the fourth year Branches are pruned to ensure high yield. The rootstock building method of the present invention not only has the advantages of low cost, neat garden appearance, small amount of pruning in the later stage, fast forming, strong tree vigor, good high yield, high quality fruit rate, etc. Well, at the same time, this rootstock gardening method bears fruit 2‑3 years earlier than traditional gardening.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for building a rootstock for early fruit and high yield of apple trees. Background technique [0002] For a long time, most of the apple orchards have been built with finished seedlings. Not only the survival rate of the seedlings is low and the investment cost is high, but also the species of the seedlings cannot be guaranteed. As a result, most apple orchards have problems of mixed varieties, low yields, and poor returns. For this reason, high-standard apple orchards can be built by using apple seedlings planted in spring and grafted in autumn, selecting medium and short-branched apple varieties, and through comprehensive cultivation techniques such as timely topping, carving buds, and plastic film mulching. It not only ensures the purity of sapling species, but also reduces the input of nursery stock for garden construction, which is suitabl...

Problems solved by technology

Since the traditional seedlings are usually grafted at 10cm above the root stock, the tree is free-spindle-shaped, and the distance between plants and rows is 3×4m or 4×5m. After planting, the full buds are selected at about 100cm to set the stem, and the tree will branch randomly after the stem. , the branches below 80cm from the main trunk are useless branches, which must be cut off year after year, causing more damage to the tree and affecting the cultivation of main branches above 80cm. , low photosynthetic efficiency, low fruit yield
