The Daguangyan longan tree planting method is obtained by summarizing in years of Daguangyan longan tree planting, and is effective according to practical tests. Before large-scale planting of Daguangyan longan trees, steps of orchard construction, strong seedling selection, sapling management, mature tree fertilization, pruning, insect disease prevention, timely picking and the like for producing Daguangyan longan fruits are completed. The variety of Daguangyan longan trees is one of excellent varieties of longan trees, and the Daguangyan longan trees are fine in fruiting performance, ordered in fruit shape, attractive in appearance, tender in pulp, superior in quality and is wide in applicability, heat-resistant, drought-resistant, disease-resistant and suitable for large-area planting.

Description

A kind of cultivation method of large wide eye longan

Technical field:

The invention belongs to the fruit tree planting technique field, relate in particular to a kind of kind and be the cultivation method of large wide eye longan.

Background technology:

Longan, evergreen megaphanerophyte, the tree height is large, and fruit is spherical, and seed black is glossy, and the florescence 3-4 month, the fruit phase 7-8 month, the happiness temperature is avoided and is frozen.According to incompletely statistics, the whole nation has more than 400 longan cultivars approximately, but as the wherein dozens of that only has of main breed, as: good fortune eye, Dong Bi, oily pool basis, oolong mountain range, water rises, large wide eye, the precious circle of blue or green shell, red shell, Gaozhou Chuliang Longan, stone gorge, dragon are excellent, crow circle, wide eye, Pu Mingan, southern No. 1 of water, flat casket are attained, Song Fengben, No. 0, green hill, friendship 106, the Beginning of Winter basis, powder shell etc.The present invention is that kind is the cultivation method of large wide eye longan, large wide eye longan tree crown spheroidal, and leaf green, fruit ear is large, it is closeer to bear fruit, and fruit meat is thick and sharp and clear, and it is fragrant and sweet to distinguish the flavor of, and seed is pitch-black or reddish brown, sepia, oblateness, the kind skin is smooth without wrinkle, is the Table and processing kind.Large wide eye arillus longan is nutritious, and pulp contains complete sugared 13-20%, reducing sugar 4-10%, full acid 0.1%, also contains in addition the compositions such as protein, fat, phosphorus, calcium, iron, tartaric acid, adenine, choline, vitamin B1 .B2.C.Longan is not only a kind of fruit of deliciousness, also have the multiple efficacies such as establishing-Yang benefit gas, tonifying heart and spleen, nourishing blood and tranquilization, moistening skin beautifying after edible, can treat anaemia, palpitaition, insomnia, forgetful, neurasthenia and after being ill, disease, the effect of have beauty treatment concurrently, promoting longevity such as postpartum is in poor health.The leaf of longan, flower, root, nuclear all can be used as medicine in addition.The cultivation of large wide eye longan mainly should be carried out following work: build the garden 1.; 2. cultivate strong sprout and field planting; 3. earsh management; 4. become the tree management, comprise water and fertilizer management, beta pruning, prevention and elimination of disease and pests, wherein the method for beta pruning is that trimming method, the dense planting longan arboretum of cutting back adopt sparse branching retraction method to prune, note when prune autumn cultivating in good time, effective autumn growth, the short flower of the control winter tip to young longan pruning employing in age sparse branching; 5. in time pluck longan fruit; 6. management in autumn.Should large wide eye longan be one of improved seeds of longan, tree be long vigorous, and performance is good as a result, and fruit shape is neat, and outward appearance is beautiful, and pulp is delicate, and quality is first-class, and this varietal adaptation is wide, heat-resisting, drought-enduring, resistance against diseases strong, be adapted to establishing in large scale.

Summary of the invention:

The problem that the present invention mainly solves provides the method for the large wide eye longan of a kind of commerial growing, and the method is through practice test, and is respond well.

The method of the large wide eye longan of a kind of commerial growing is characterized in that being made of following steps:

1. build the garden: should select during the large wide eye of plantation longan that the leeward loosing soil that faces south, soil layer are deep, the soil such as good permeability, red soil that the preserve moisture and fertility ability is strong, yellow soil, sandy loam, fluvisol, good irrigation and drainage condition are arranged.

2. select strong sprout: high-quality strong sprout is the key that guarantees survival rate and high yield, should select healthy and strong and well-developed sapling when planting, require that plant strain growth is healthy and strong, the leaf look dark green, fibrous root is flourishing, without damage by disease and insect, above aging branch is arranged more than the grafting grafting mouth twice; 0.9 meter of planting pit is square, and drenches sufficient normal root water, uses sufficient base manure.

3. treelet management: will guarantee the Enough supply of moisture content to the longan treelet, fertilising should be executed as principle take Bao Shiqin, generally can topdress 1-2 time per month, take instant nitrogenousfertilizer as main, is equipped with phosphorus potash fertilizer; Management will surely be done, stay major branch, be dredged and go branch and pest control overstocked, overlapping, that intersect to tree crown.

4. become the tree fertilising: rare liquid manure that becomes thoroughly decomposed of executing for the first time 0.2 kilogram of potassium sulphate and 0.2 kilogram in late Febuary to early March by every strain; To early April, execute autogamy composite organic-inorganic fertilizer double centner at late March the second time; For the third time mid-May to early June, 1 kilogram of every strain sealing fertilizer, 0.3 kilogram of potassium sulphate, 0.3 kilogram in urea, 0.3 kilogram in the U.S. phosphate fertilizer of calcium.　　

A kind of cultivation method of large extensively eye longan, its beneficial effect is: large wide eye longan is grown up strong and sturdy, and production there emerged a large delicious high-quality large wide eye longan fruit.

Embodiment:

1. prune: for making large wide eye longan a good tree crown is arranged, improve the output of longan unit are, the pruning of large wide eye longan will carry out twice in 1 year, and spring, pruning will be carried out in conjunction with flower and fruit thinning, the pruning in autumn will be in conjunction with the pruning of carrying out tree-like tree crown after the fruit picking, the branch of growth vigor too retraction, the weak branch in the tree crown, the snag after the just fruit picking, sick branch, the branch that intersects prunes away, and improves the ventilating air permeability in the tree crown, recovers tree vigo(u)r.

2. prevention and elimination of disease and pests: the disease of large wide eye longan mainly contains Longan Witches ' Broom, anthracnose, peronospora tabacina, and the method for preventing and treating of Longan Witches ' Broom is: control vector insect, in time wipe out the disease fringe, improve the plant premunition; Anthracnose, peronospora tabacina are prevented and treated with 1200 times of many Mils of liquid thunder; Insect pest has the insects such as base of a fruit moth, last of the twelve Earthly Branches gelechiid, longan wood louse, fruit moth, the thin moth of Ai Wen, can adopt 20% to go out and sweep sharp 1800 times of liquid or 10,%00 and go out and can spray by 1800 times of liquid, every spray in 20 days once, until young sprout aging till.

3. in time pluck: because of large wide eye longan storage endurance not, timely collecting is to improve a really important ring of food quality of large wide eye longan, in time pluck, fresh-keeping and timely sale.
