Embodiment 1

[0015] The apple high-yield method of high-density continuous cropping aging garden, it comprises the following steps:

[0016] (1) Crown reduction and reshaping: according to the planting density of apple trees in the park, reshape the fruit trees, adopt a tree shape with a small crown and a happy shape, and meet the following conditions: For thinning, keep the total height of the trunk at 2.5 meters, keep 3 non-overlapping main branches on the trunk, keep the branches and tendrils of the main branches, leave only one strong seedling on the branches and tendrils, and cut off all the others, and pick the heart when the strong seedlings extend to 50cm; Or in parks where the row spacing is less than 4 meters, the total height of the trunk is 4 meters, and 5 non-overlapping main branches are reserved on the trunk;

[0017] (2), fertilization management: the raw material of following parts by weight: 25 parts of rice bran, 15 parts of nitrogenous fertilizers, 10 parts of phosphate...

Abstract

The invention discloses a high-yield promotion method for apples in a high-density continuous-cropping aged orchard. The method comprises the following steps: (1) crown-shrinking and reshaping: a step of reshaping an apple tree according to apple-tree planting density of the orchard, wherein a small-crown open-center tree shape is adopted; (2) fertilization management; (3) apple-tree pollination: a step of continuously spraying pollens with a backpack sprayer for 2 to 3 times by adopting an artificial pollination manner when more than 80% of central flowers bloom and more than 50% of flowers in the whole orchard bloom; (4) apple-fruit bagging; and (5) fertilizer topdressing: a step of starting increasing foliage fertilization by twice to three times in 3 to 5 days after apple-fruit bagging. The invention has the following beneficial effects: the method fully respects and utilizes habits and characteristics of growth and fruiting of the apple tree, so photosynthetic efficiency and nutritive accumulation level are greatly improved; meanwhile, the method is favorable for field operation, opens light paths of the orchard, increases light receiving area of an orchard inside cavity, promotes nutrient accumulation, solves the problem of canopy density of a conventional high-density continuous cropping aged orchard, and improves yield and quality of an apple orchard.

Description

technical field [0001] The invention relates to a method for high-yielding apples in high-density continuous cropping orchards for the elderly, and belongs to the technical field of crop planting. Background technique [0002] At present, the direction of Apple's development has transitioned from quantity to quality. With the growing maturity and improvement of the fruit market, the contradiction between market demand and apple quality competition has gradually become prominent. From a market point of view, high-quality apples sell well and have high prices, while poor-quality apples are not sold well and cannot be sold at a high price. Therefore, the era of quality has come. It is very important to improve the quality of apple fruit. The poor quality of apples is mainly manifested in the small size of the fruit, the shape of the fruit is not correct, the fruit shape index is low, the fruit surface is not smooth with stains, rust spots, poor coloring, and the color is not b...
