A Detailed Guide to the Cultivation Techniques and Management Methods of the Emperor Mandarin

The Emperor Mandarin is a fruit formed by natural hybridization, combining the appearance and flesh of other tangerines. The Emperor Mandarin has an attractive fruit shape, golden fruit, thin peel, few seeds, crisp and residue-free flesh, sweetness, high sugar and low acid, and a rich flavor. Such a fine fruit, of course, is loved by many people. If you grew one yourself, wouldn't it feel great? Let's take a look below at how to grow it.

How to Grow Emperor Mandarin

1. Preparation of Good Varieties

(1) Seedling selection: In the early stage, we need to choose land with good isolation conditions, convenient irrigation and drainage, deep, loose, fertile, slightly acidic soil that has never been planted with citrus, as the seedling-raising base, select varieties suitable for category growth and maintain the quality of the tribute fruit.

(2) Seed treatment: Before sowing, plow the soil until it turns white, plow repeatedly, make the soil fine and crumbly, and apply sufficient decomposed organic fertilizer. Seeds are subject to quarantine; before sowing, treat with warm water at 55°C for 50 minutes, select mother plants of single trees with stable traits, high yield, stable yield and excellent quality as scions, graft the scions after detoxification treatment, and establish a scion-collection orchard for seedling raising. Establish a mother orchard for producing tribute mandarin seedlings, collect scions from the scion-collection orchard for grafting (grafting tools and materials must undergo strict disinfection treatment), and use the above methods to produce stable, early-fruiting, high-yielding tribute mandarin seedlings for field production, and stable citrus seedlings for field production.

2. Selection of the Orchard Site

Choose sandy loam land with loose soil, good permeability, favorable for deep roots, suitable for tree growth, suitable for the growth of tribute mandarin, and never previously planted with other crops, as the tribute mandarin production base; before planting, deeply plow and apply sufficient base fertilizer.

3. Planting of Seedlings

(1) Planting season: Winter and spring planting, autumn can also be used; generally, when the new buds of the seedlings mature, up to the planting bud.

(2) Planting specifications: Row spacing 2.5X3 (m), 80-100 plants per mu, with more than two branches, developed root system, green leaf color, and free of disease and pests is preferable.

(3) Pruning treatment of seedlings: First cut the seedlings into two-needle or three-needle seedlings, seedling height 20-30 cm, and moderately cut the roots.

(4) Disinfection treatment of seedlings: Soak in a solution of Wanling 800 times + Nuotanning 500 times for about 1 minute, take them out, and place them in a cool place to dry.

(5) Root treatment of seedlings: Dig out a root, take some yellow mud, mix it into a paste with an appropriate amount of water, and coat the roots of the disinfected seedlings that have been slightly dried and are not dripping water. Plant the treated seedlings into the already prepared ground; paddy fields need deep furrows and high ridges, dry land needs holes dug and sufficient base fertilizer applied; when planting, require the root system to spread naturally, the trunk to be upright and not tilted, press soil in layers, with appropriate tightness, pressing soil from outside to inside, and the burial depth should be slightly higher than the root crown; after planting, water thoroughly to settle the roots, and moisten every day so they can survive.

Digging planting holes in soil: Pull lines for distance, dig planting points, hole depth and width 80 cm, then press green manure 50 cm deep, backfill soil 40 cm high for planting; ridge planting in fields: Open compartments with 8-meter belts and ditches (ditch width 60-80 cm, depth 40-60 cm), each compartment forms 2 ridges (ridge width 1.5 m, ridge center distance 4 m, ridge height 20-30 cm). When planting, moderately prune the root system of the seedlings, place them in the center of the planting hole, spread the roots, hold them upright, and while filling soil, gently lift the seedlings upward and firm the soil, so that the roots are in close contact with the soil. Water thoroughly to settle the roots, make a 1 m tree disc around the sapling, and cover with chaff so as to sprout.

1. Management Methods for Emperor Mandarin Cultivation

1. Fertilizer and Water Management

(1) The various nutrient requirements of blood orange should be fully met, and fertilization should be advocated. Fertilization should also be guided according to leaf analysis results, orchard soil analysis results, and the phenological period of blood orange. Soil fertilization is the main method, combined with foliar fertilization. Use ring groove application, groove application, hole application and soil surface spreading methods.

(2) Fertilization for mature trees

Fertilization for adult trees is very important, and there are also techniques; apply four good fertilizations, namely sprouting fertilizer, fruit-preserving fertilizer, fruit-strengthening fertilizer, and post-harvest fertilizer. Fertilization amounts are generally 2-3 jin of chemical fertilizer and one load of manure water for sprouting fertilizer; 1-2 jin of phosphorus and potassium fertilizer + 1 jin of chemical fertilizer for fruit-preserving fertilizer; 1-2 jin of chemical fertilizer + 1-2 jin of phosphorus and potassium fertilizer for fruit-strengthening fertilizer; post-harvest fertilizer (base fertilizer) is mainly organic fertilizer, applying 50-100 jin of organic fertilizer + 1-2 jin of chemical fertilizer per tree. (4) Water: Irrigate when the soil is dry, drain when there is standing water, so that they do not die.

(3) Fertilization for young trees

Fertilization for young trees requires attention: be sure to fertilize more often, and do not apply too much each time; mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer; fertilize 5-6 times during the spring, summer and autumn shoot sprouting periods (March, May, June, July, September, December, each time applying 0.4 jin of ammonium bicarbonate or 0.2 jin of urea per tree. For 1-3 year old young trees, apply 100-400 g of pure nitrogen per tree per year, and the ratio of nitrogen, phosphorus and potassium is preferably 1.0:(0.4-0.5):1.0, so that the young trees have nutrition.

2. Soil Management

Holes should be deepened, and the soil should be matured and expanded; planting tall-stemmed plants such as corn and wheat in the orchard is prohibited; do a good job of reasonable intercropping in the orchard and cultivation weeding.

Can Pesticides Be Sprayed During the Flowering Period of Emperor Mandarin?

Except during the flowering period, do not spray pesticides, so as not to affect pollination and fertilization; at other times, spraying is fine, and during the young fruit period, just pay attention to reducing the concentration. When spraying, you can add Weibu Guoli + Weibu Boron; spraying before flowering can strengthen the flowers and increase the fruit-setting rate; spraying after flower drop can promote even development of young fruit and is beneficial for fruit preservation.

The characteristics of the Emperor Mandarin are fine and crisp flesh, light color, no residue, few seeds, and a sweet taste on entering the mouth, and it is deeply loved by the general public. However, growing an Emperor Mandarin tree is not a simple matter, and everyone needs to put in some effort in caring for it; only then can you grow good fruit.
