Description

A kind of engrafting method of oil tea
Technical field
The invention belongs to field of planting, be specifically related to the engrafting method of a kind of oil tea.
Background technology
Oil tea is that time-honored woody section oil crop, one of big woody oleiferous plants crop in the Ye Shi world four are planted by China. Oil tea is suitable for cultivation in the area of warm and moist, and higher to the requirement in precipitation and sunshine duration, oil tea is main Distribution be the Northern Hemisphere.Oil tea has nutritive value, economic worth and the ecological value.The unsaturated fatty acid content of oil tea Up to about 90%, exceed 7% than olive oil, oleic acid content reaches 80%~83%, and linoleic acid reaches 7%~13%, and rich in dimension Raw element A, B, D, E etc., have the good reputation of " east olive oil ".Oleum Camelliae because its oil is good, there is stronger non-oxidizability, health care merit Global top quality edible vegetable oil can be become well, be eaten for a long time and cardiovascular and cerebrovascular disease is had good health care work With.Oleum Camelliae is except being used for eating, and can also continue to deep processing becomes the deep processed products such as oil for health care, oil for injection.Oil tea Economic worth is mainly reflected in the value of Oleum Camelliae and intensely processed products thereof.The ecological benefits of oil tea are notable, can in deserted mountain or Person wasteland suitable for afforestation is planted, and oil tea belongs to evergreen species, well developed root system, can play and improve region miniclimate, minimizing disaster caused by a windstorm, prevent Soil erosions etc. act on.Owing to oil tea is the most fire-resistant and nonflammable, in forest, therefore play fire prevention, the work of prevention fire spreading With, the existence of camellia oleifera lam simultaneously can increase the content of the humus of soil, accelerates maturation and the atmospheric disintegration of rocks of soil, improves The soil regime in forest land.
Plantation oil tea can drive local agricultural, increases the income of peasant.At present, the plantation side of existing oil tea Method is sowing, grafting and cuttage.Sowing is that Seed of Camellia oleifera is directly sowed at seedbed, and cultivation is emerged, and this is conventional seedbed system method, Its weak point is that forest is very different, survival rate and yielding poorly;In order to keep the merit of parent, use cuttage or grafting Nursery, then carries out forest planting;Grafting is to select C. olelfera large seed, transfers anvil at indoor sand bed Pregermination and seedling breeding, selects Grow sturdy, axillalry bud substantially, make scion without the saturated oils tea shoot of the current-year branch of pest and disease damage, but grafting is in stock cultivation Take considerable time and cost, and grafting time receives stock and cultivates the restriction of time.
Summary of the invention
It is an object of the invention to provide the oil tea engrafting method that a kind of survival rate is high, diseases and insect pests resistance is strong.
In order to realize the purpose of the present invention, adopt the following technical scheme that
The engrafting method of a kind of oil tea, comprises the following steps:
(1) stock is cultivated: by high-quality, disease-resistant and floorboard with high oil content Seed of Camellia oleifera with 0.2% potassium permanganate solution immersion 1~ 2h, is seeded in after cleaning up in husky bed, then covers 6~10cm thick wet fluvial sand, waters permeable, cover thin film moisturizing, treat oil Tea seed germination also makes plumule grow to 3~7cm, is i.e. ready for grafting;
(2) collection of fringe bar and process
Select in tree crown periphery, top leaf bud is full gives birth to lignifying then, without the spring tip of pest and disease damage or the summer of semi-lignified The tip is scion, fringe thick 0.28~0.35cm;
(3) nursery lot selects and pretreatment
Nursery selects: nursery lot is selected in and has a good transport service, leeward on the sunny side, it is simple to the place of irrigation and drainage, it is fertile that the soil is porous, soil Deep, the yellow earth of pH value 5.5~6.0 or yellow sand earth;
Nursery pretreatment: wholely, every mu of ground carries out parasite killing and soil disinfection with 8~10kg ferrous sulfate, places 10~25 After it, apply fertilizer to the subsoil, every mu use the 20~35kg cake fertilizer become thoroughly decomposed, 25~40kg compound fertilizer, 10~20kg siliceous fertilizer and 300~ 500kg Tujia is fertile, then ploughs under in soil;Making seedbed, seedbed wide 90~110cm, seedbed performs bonnet last layer yellow soil, thickness It is 5~10cm, plastic sheeting moisturizing on spray bonnet;
(4) cool canopy is set up
Setting up cool canopy, canopy high 1.8~2m, shade density 50%~70% before grafting on nursery, ceiling shelters from heat or light material with green Color two pin or black three pin sunshade net;
(5) grafting
A: grafting time: graft in mid or late May or early or mid June is carried out;
B: cut scion: cut off the 1/3~1/2 of fringe bar blade, is starting a cutter of splaying, tiltedly at petiole base 0.2cm Face becomes 30 °, the long 1.2cm in inclined-plane, then overturns scion and the first cutter symmetry and splay a cutter, and making scion is thin wedge shape, the smooth light of bevel Sliding, finally oblique partial application at 0.2cm above cusp, cut off scion;
C: cut Seedling anvil: taken out from sand by anvil Seedling, is placed in water and cleans silt, avoid touching off the kind on anvil Seedling when taking anvil Seedling Son and touch the portion of being completely cured;Radicle stays 4~6cm, unnecessary blocks, and cuts off at the 2cm of cotyledon petiole top, and alignment stock axis cuts one Cutter, dinting depth is 1.2~1.5cm;
D: grafting: the anvil bud cut is placed on the strip waste toothpaste tubes sheared in advance, then by the thin wedge shape wood of scion Matter portion inserts Seedling anvil, and anvil bud aligns with scion, and scion bevel slightly shows money or valuables one carries unintentionally, and is finally clutched by toothpaste;Graft Root soaks 10~15s in 80mg/L rooting powder solution;
E: plant: by the nursery stock transplanting that grafts to seedbed, seeding row spacing of planting is 5 × 12cm;First with bamboo spike in seedbed On dig a hole, then the oil tea Seedling that grafts is inserted in hole, earth backing makes stock root system unfold, and the degree of depth to expose interface toothpaste is Preferably, irrigate and determine root water, then take a length of 1.8~2m bamboo strip some, curve arch and insert in both sides, seedbed, upper cover plastics are thin Film, thin film surrounding grave pressure is tight;
(6) manage after connecing
A: except sprouting roguing: after transplanting 20~30 days, pulls out the weeds on seedbed in time, removes and do not take over a job and the stock of death Seedling, the bud wiped out on the rudiment taking over a job on rootstock seedling and excision seedling;
B: temperature control and moisturizing: rainy weather, timely draining, reduces thin film and covers, increase transmittance;Hot weather, opens Seedbed thin film, aeration-cooling and keep the skin wet in time;
C: topdress: Seedling to be grafted grows to 5~8cm, and every mu sprays 35~45L nutritional solutions, and described nutritional solution is by following heavy The raw material composition of amount part: boric acid 1~3 parts, ammonium molybdate 0.5~2 parts, potassium sulfate 5~10 parts, carbamide 10~20 parts, water 50~90 Part;
D: the prevention and control of plant diseases, pest control: the Major Diseases of grafting is southern blight, prevention and controls, for pulling out diseased plant, then sprays 50% Carbendazim 600~800 times of liquid.
Preferably, in step (2), the collection of fringe bar is carried out when having dew in the morning between 6 o'clock to 9 o'clock.
Preferably, described nutritional solution is made up of the raw material of following weight portion: boric acid 1 part, ammonium molybdate 1.5 parts, potassium sulfate 8 Part, 16 parts of carbamide, 75 parts of water.
Beneficial effects of the present invention:
The oil tea engrafting method using the present invention to provide, is effectively increased graft survival rate, and survival rate is up to more than 92%, Ensure that the economic benefit that oil tea is planted, there is important actual application value;By the rational application of fertilizer, meet oil tea when difference The phase demand to fertilizer, adds the speed of growth of oil tea.
