Description

Technical Field

[0001] The invention belongs to the technical field of Wogan cultivation, and specifically refers to a high-yield cultivation method for Wogan. Background Art

[0002] Wogan is a perennial evergreen fruit tree of the genus Citrus in the Rutaceae family. It belongs to the spring orange and is a late-maturing hybrid citrus variety. This variety has the characteristics of vigorous growth, less fruit falling in winter, strong fruit-bearing ability, and a long fruit-bearing harvesting period. It can be harvested and put on the market from January to February during the ripening period, and can be harvested as late as May. The fruit is full and festive in appearance, with tender and smooth flesh, thin skin, orange flesh, and rich juice, so it tastes sweet and soft, low in acid and refreshing, and has high nutritional value and contains a large amount of vitamins.

[0003] The efficiency of Wogan is low when planted on a large scale. In addition, diseases and insect pests of Wogan will affect the yield of Wogan, which is not conducive to the healthy growth, high yield and high quality of Wogan. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-yield cultivation method of Wogan. This scheme aims to provide a cultivation method that can efficiently cultivate Wogan, control pests and diseases, make the Wogan grow faster, and improve fruit yield and quality.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a high-yield cultivation method of Wogan, comprising the following steps:

[0006] Step 1: Planting site selection: Plant in areas with an annual average temperature of 18℃ to 22℃ and a minimum winter temperature of no less than -2℃;

[0007] Step 2: Select seedlings and plant them: Select seedlings with uniform plant shape and complete root system, and select disease-free Wogan seedlings for cultivation, so as to control the occurrence of diseases and insect pests from the source, and then water and plant them;

[0008] Step 3: Planting density management: Plant 110-115 mandarin orange plants per acre, with half of them being temporary plants and half being permanent plants;

[0009] Step 4: Water and fertilizer management: The base fertilizer is rotten and fermented farmyard manure and compound fertilizer; topdressing is done 3-4 times a year, during the spring shoot growth period, fruit stabilization period, autumn shoot growth period and after fruit harvest, mainly nitrogen fertilizer;

[0010] Step 5: Shaping and pruning: Use a natural open-heart shape or a modified trunk shape, keep the tree ventilated and light-permeable, and remove summer shoots in time to promote flower bud differentiation;

[0011] Step 6: Pest and disease control: Select appropriate pesticides for prevention and control of different pests and diseases.

[0012] Furthermore, in step 1, the plant is planted in a sandy loam or red-yellow soil plot that is sheltered from the wind and facing the sun, has a slope of less than 15°, has a deep soil layer, is loose and fertile, and has good drainage, and has a pH value of 6.0-6.5.

[0013] Furthermore, if the planting area in step 2 is alkaline soil, sour orange and red orange can be selected as grafted rootstocks; if the soil is paddy field, broadleaf trifoliate orange can be selected as grafted rootstock.

[0014] Furthermore, in the step three, the temporary plants are citrus aurantium seedlings grown on Citrus aurantium rootstocks, and the permanent plants are large seedlings grown on Citrus aurantium rootstocks or Citrus aurantium rootstocks.

[0015] Furthermore, in step 4, phosphorus and potassium fertilizers are applied simultaneously, 1.5-2 kg per plant; in the rainy seasons of spring and summer, accumulated water should be removed in time, and in the autumn and winter when drought occurs, water should be irrigated and covered to keep moisture.

[0016] Furthermore, in step 4, the drainage management of the orchard is strengthened, the humidity of the orchard is reduced, the breeding of pathogens and pests is avoided, and the orchard is cleaned regularly, and fallen fruits, broken branches and leaves are taken out of the orchard for centralized destruction to reduce the overwintering places for pests and diseases.

[0017] Furthermore, in step five, the principle of "one pole and three branches" is followed during the sapling stage to increase the tree crown and improve the future fruit-bearing rate; pruning during the fruit-bearing period can reduce the amount of medicine used, and the effect is more effective, and it is also more conducive to strengthening the inner branches and hanging the inner fruits.

[0018] Furthermore, in step six, the ulcer disease is treated by spraying with Jinguoan; the anthrax treatment drug is a copper hydroxide water dispersion; during the high incidence period of pests and diseases, it is necessary to focus on preventing and controlling pests such as rust mites, and avermectin is used for spraying.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. Through the prevention and control of diseases and insect pests of Wogan, and flexible application in combination with actual conditions, diseases and insect pests of Wogan can be effectively prevented and controlled, ensuring the healthy growth, high yield and high quality of Wogan;

[0021] 2. Pruning the mandarin oranges according to certain pruning principles and time nodes can cultivate a strong mandarin orange tree shape and improve the fruit yield and fruit quality. DETAILED DESCRIPTION
