Problems solved by technology

[0003] The loquat has been planted for about 15 years. Due to one-sided pursuit of yield, unreasonable fertilization and pest control, neglect of pruning, excessive dense planting, and excessive fruiting, etc., the backward management methods have resulted in the loquat tree being too upright and tall, with messy branches and many bare branches. , Thin green leaf layer, weak new shoots, few and small leaves, outward shifting of fruiting parts, small fruit shape, low yield, poor quality, low economic benefits and other decline phenomena
At present, fruit farmers choose natural regeneration for declining loquat trees, but affected by natural conditions and human interference, natural regeneration is relatively slow, and the effect is not ideal

Embodiment 1

[0022] (1) Reasonable thinning and retraction pruning: one week after fruit picking, that is, in late June, the row spacing of loquat plants is generally 4m×6m for thinning the plants that are too dense; the trunk of the tree that is too high is cut down, and the height is controlled at about 3m. , Most of the branches with a thickness of 2cm in the crown should be short-cut and retracted at a distance of 25cm from the branches, and the wounds of the retracted branches should be flat and cracks should not appear;

[0023] (2) Prevention and control of diseases and insect pests: Spray 800 times of 80% mancozeb visible powder, 1000 times of 20% high chloride zinc on the leaves, leaf backs and trunks in early July, 12.5% The disease mixture of 3 000 times liquid of Nitrile emulsifiable oil;

[0024] (3) Improving the soil: In mid-July, expand the hole and deep plow the soil on both sides of the canopy of the declining loquat tree. The length, width and depth of the hole are 150cm...

[0028] (1) Reasonable thinning and retraction pruning: one week after fruit picking, that is, in late June, the row spacing of loquat plants is generally 4m×6m for thinning the plants that are too dense; the trunk of the tree that is too high is cut down, and the height is controlled at about 3m. , Most of the branches with a thickness of 2.3cm in the canopy should be short-cut and retracted at a distance of 27cm from the branches, and the wounds of the retracted branches should be smooth and cracks should not appear;

[0029] (2) Prevention and control of diseases and insect pests: Spray 70% on the leaves, leaf backs and trunks in mid-July to get 800 times liquid of wettable powder, 800 times liquid of chlorothalonil, and 800 times liquid of 80% mancozeb wettable powder disease mixture spray;

Embodiment 3

[0034] (1) Reasonable thinning and retraction pruning: one week after fruit picking, that is, at the beginning of July, the row spacing of loquat plants is generally 4m×6m when thinning the plants that are too dense; Most of the branches with a thickness of 2.5cm in the crown should be short-cut and retracted at a distance of 30cm from the branches, and the wounds of the retracted branches should be flat and cracks should not appear;

[0035] (2) Pest control: Spray 70% of the leaves, leaf backs and trunks in early July to kill 800 times of wettable powder, 800 times of chlorothalonil, and 800 times of 80% mancozeb wettable powder disease mixture spray;

[0036] (3) Improving the soil: In mid-July, expand the hole and deep plow the soil on both sides of the canopy of the declining loquat tree. The length, width and depth of the hole are 150cm×60cm×50cm, and the holes are filled with straw and calcium magnesium phosphate fertilizer in layers. back cover soil;

Abstract

The invention discloses a method for renewing and rejuvenating declined loquat trees. The method comprises the measures: (1) reasonably carrying out intermediate cuttings and retraction pruning; (2) preventing and treating diseases and insect pests; (3) improving soil; (4) carrying out fertilizer application management; (5) carrying out blossom and fruit thinning. The method for renewing and rejuvenating disclosed by the invention is simple and easy to popularize; after the declined loquat trees are manually renewed and rejuvenated for five to seven months, the loquat trees have luxuriant foliages, large fruit shapes, high yield and good quality; the economic benefits are improved; the method is particularly suitable for renewing and rejuvenating the declined loquat trees.

Description

technical field [0001] The invention relates to a method for regenerating and rejuvenating a declining loquat tree, in particular to a method for rejuvenating and rejuvenating a declining loquat tree. Background technique [0002] Loquat, also known as Jinwan, Luzhi, and Pipaguo, is a plant of the genus Loquat in the Rosaceae. Loquat pulp is soft and juicy, with high sugar content, unique flavor, rich in various nutrients and medicinal value. It is a treasure among fruits and is deeply loved by consumers. Loquat likes light, is slightly shade-tolerant, likes warm climate and fertile, moist, well-drained soil, is slightly cold-resistant, not cold-tolerant, grows slowly, the average temperature is above 12-15°C, not lower than -5°C in winter, and the flowering and young fruit stages are not low It can grow well in the area of ​​0 ℃. [0003] The loquat has been planted for about 15 years. Due to one-sided pursuit of yield, unreasonable fertilization and pest control, neglect...
