Example Embodiment

[0022] The principles and features of the present invention will be described below in conjunction with specific examples, which are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0023] A high-yield planting method of tribute mandarin oranges, comprising the steps of:
[0024] Step 1, select the garden: firstly, it is necessary to ensure that the annual average temperature of the garden is between 15°C and 23°C, and at the same time, the annual sunshine amount needs to be more than 1600 hours, and the annual precipitation must be greater than 900mm; secondly, choose soft, deep soil, and relatively relatively water level. Low loess with good drainage conditions. In terms of land properties, neutral soil is ideal, and the best pH value is between 5.6 and 7.2. Avoid wind passages or locations with strong winds all year round;
[0025] Step 2, Planting: Plant in the season with abundant rainfall, because the root system is easy to recover when planted in this period of abundant precipitation, and the survival rate is relatively high, the germination time in the next spring is relatively early, and the growth is relatively large. The most suitable planting method for tribute mandarin oranges is close planting, the distance between plants and rows is 3 meters x 3 meters, and 1200 plants are planted per hectare;
[0026] Step 3, manage fertilizer and water:
[0027] (1) Fertilization cycle: ensure 4 to 5 times a year, and apply the pre-flowering fertilizer in the first ten days of March to promote the flowering and fruiting of trees and the growth of branches and leaves. Among the fertilizers, quick-acting nitrogen fertilizer is used as the main fertilizer to ensure that each plant can be applied 5 kg of human and livestock manure, 0.5 kg of 45% potassium sulfate compound fertilizer. Phosphorus and potassium fertilizers are added in the later stage of flowering, accounting for about 20% of the annual fertilization amount. In late May, during the fruit expansion period, 0.5 kg of 45% potassium sulfate compound fertilizer was applied to each plant, accounting for 30% of the annual fertilization amount. From mid-August to late September, within seven to 10 days after harvesting, 5 kg of human and livestock manure and 0.5 kg of 45% potassium sulfate compound fertilizer should be applied to each plant, and quick-acting fertilizers should be used as the main fertilizer. Begin to apply base fertilizer in autumn, organic fertilizer is the main fertilizer, accounting for 40% to 50% of the total annual fertilization amount, to ensure that each plant can apply 30 kg to 50 kg of farmyard manure per month and 2 kg of phosphate fertilizer per month;
[0028] (2) Fertilization method: When applying base fertilizer, use any one of the following two methods: first, use the trunk as a center, open a ring-shaped ditch around the appropriate position of the crown on the outer edge of the crown, and apply the fertilizer directly Fertilize, and ensure that the rotation is carried out every year, expanding according to the passage of time, and gradually deepening; the second method uses the trunk as a center, digs a number of radioactive ditches outside, and then applies fertilizer;
[0029] Step 4, pruning and adjustment: Slightly pruning some overlapping branches, crossing branches, branches with diseases and insect pests, etc., in this way to ensure ventilation and light transmission. The extended branches of each backbone branch need to be pruned in time to ensure that the remaining length is 30 cm. Different fruiting branches need to be pruned in different ways according to different growth conditions. Make sure the main branch has the proper angle. In the fruit loading stage, set up columns appropriately for support; use oblique branches to replace the original extension branches; keep as few fruits as possible on the branches of the extension branches;
[0030] Step 5, Thinning of flowers and fruits: Thinning of fruit and flowers needs to be carried out at the separation stage of the inflorescence and the initial flowering stage, fully considering the tree vigor and the amount of flowers to carry out appropriate thinning, the specific thinning amount is 40% to 60% between. The thinning of the fruit should be carried out two weeks after the flower fades, calculated according to the leaf-to-fruit ratio, to ensure that there can be one fruit between every 25 to 30 leaves;
[0031] Step 6: Bagging the fruit: Choose a suitable double-layer fruit bag with black inner and outer flowers or a three-layer fruit bag with white inner and outer flowers and black in the middle, and put it on 30 days after the flowers fall. Specific operation method: Spray insecticide once before bagging, and complete bagging within seven to ten days to ensure that there is a certain gap between the bag and the pear fruit when bagging. Then use West Iron West to bind the mouth of the bag to prevent the horn from appearing;
[0032] Step seven, prevent and control pests and diseases
[0033] (1) Spray a 50% carbendazim solution and a 5% beta-permethrin solution once when the bud scales loosen and disperse to ensure thorough mixing. Before bagging, spray insecticide evenly once to avoid pests from entering the bag and ensure that the fungicide treatment can be well coordinated. Choose Dasheng, thiophanate-methyl, 5% avermectin and 20% Acetamiprid together for control;
[0034] (2) Prevention and control of Huanglongbing disease: Before germination, properly spray Baumedo lime sulfur and 0.3% sodium pentachlorate and mix thoroughly, and use the mixed solution to kill the germs; after germination, mix with other For joint control of diseases and insect pests, spray 200 times of Podol solution or 50% of Tuzet solution (600 times to 800 times is appropriate);
[0035] Prevention and control of spider mites: combined with winter pruning, remove overwintering insect buds, and remove damaged inflorescences and insect fruits during the flowering and young fruit stages. During the bud damage stage of overwintering larvae and the fruit damage stage in spring, spray 50% of fenitrothion emulsion, 1000 times of solution, or 20% of 2000 times of quick-killing butyric acid, 800 times of 90% trichlorfon to a 1000-fold solution.
[0036] The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
