Embodiment 1

[0036] For 20-year-old old tree orchards (such as figure 1 Shown) Use the following steps to update and rejuvenate:

[0037] (1) Fertilization: 8 days after harvesting the fruit, a ditch was dug below the drip line of the old tree crown of the old tree for uniform fertilization. The depth of the ditch was 30 cm, the length of the ditch was 1.8 m, and the width of the trench was 25 cm. Apply 12kg of bio-organic fertilizer and 1.5kg of urea to old trees. The bio-organic fertilizer is composed of dry cow dung, plant ash, rice husk and perlite in a weight ratio of 1:0.8:1:2.5, and is fully fermented and matured by yeast. After all the fertilizer and soil are mixed evenly, return to the soil and fill up;

[0038] (2) Gradation retraction: 25 days after fertilization, carry out gradation retraction to the old tree of the mountain yellow bark, choose to stay 2 main branches that grow obliquely, saw off at 25cm above the branch mouth, and the remaining main branches are not Retracti...

Embodiment 2

[0049] For 25-year-old old tree orchards, the following steps are adopted to renew and rejuvenate the old tree orchards:

[0050] (1) Fertilization: 7 days after harvesting the fruit, a ditch was dug below the drip line of the old tree crown for uniform fertilization. The depth of the ditch was 20 cm, the length of the ditch was 1.5 m, and the width of the ditch was 20 cm. Apply 10kg of bio-organic fertilizer and 1.0kg of urea to old trees. The bio-organic fertilizer is composed of dry cow dung, plant ash, rice husk and perlite in a weight ratio of 1:0.5:1:2, and is fully fermented and matured by yeast. After all the fertilizer and soil are mixed evenly, return to the soil and fill up;

[0051] (2) Gradational retraction: 20 days after fertilization, the old tree of the mountain yellow bark was retracted in stages, and 2 main branches growing obliquely were selected and cut off at 30 cm above the branch mouth, and the remaining main branches were not cut off. Retraction, afte...

Embodiment 3

[0058] Take the following steps to rejuvenate the orchards of the old orchards with 22-year-old trees, shifted parts, weak tree vigor and low yield and low efficiency:

[0059] (1) Fertilization: 10 days after harvesting the fruit of the chrysanthemum, a ditch was opened under the drip line of the old tree crown of the chrysanthemum for uniform fertilization. The depth of the ditch was 40 cm, the length of the ditch was 2 m, and the width of the ditch was 30 cm. Apply 15kg of bio-organic fertilizer and 2.0kg of urea. The bio-organic fertilizer is composed of dry cow dung, plant ash, rice husk and perlite in a weight ratio of 1:1:1:3, and is fully fermented and matured by yeast , after mixing all the fertilizer and soil evenly, return to the soil and fill it up;

[0060] (2) Gradational retraction: 30 days after fertilization, the old tree of the mountain yellow bark was retracted in stages, and 3 main branches growing obliquely were selected and cut off at 40 cm above the bran...

Abstract

The invention discloses a method for renewing old randia cochinchinensis trees, and belongs to the technical field of agricultural planting. The method comprises the following steps: (1) fertilizing; (2) retracting for several times; (3) fixing of tips; (4) pruning; (5) water and fertilizer management; and (6) disease and pest control. The method for renewing the old randia cochinchinensis trees is simple, labor-saving, fast in growth, easy in crown formation, capable of promoting early fruiting and capable of reducing cost, by means of the method, the crowns of the old randia cochinchinensis tree orchard are renewed and rejuvenated, soil fertility is enhanced, diseases and pests of the old randia cochinchinensis trees are controlled in time, the production capacity of the old randia cochinchinensis trees is effectively improved, rapid renewal and rejuvenation are achieved, the yield and quality of the old randia cochinchinensis trees are improved, high and stable yield in successive years is achieved, the high-quality fruit rate is increased, and sustainable development of randia cochinchinensis is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for renewing an old tree of phoenix bark. Background technique [0002] Shanhuangpi, commonly known as chicken skin fruit, is a perennial evergreen shrub or small tree belonging to the Rutaceae Citrus subfamily. It is mainly distributed in the south subtropical region south of the Tropic of Cancer. It is mainly produced in southwestern Guangxi, southern Yunnan, and Guangdong.
