A kind of implantation methods of L. styraciflua
Technical field
The invention belongs to plant planting field, be specifically related to a kind of implantation methods of L. styraciflua.
Background technology
The gum tree height of tree can reach 30 meters, large-scale broad leaved and deciduous broad leaved seeds.Blade 5 to 7 splits, and alternate is long 10 to 18 centimetres, long 6.5 to 10 centimetres of petiole, and spring, Xia Yese are dark green, and autumn, the leaf look became yellow, purple or redness, fallen leaves evenings, at some areas blade, hung tree until be extraordinary ornamental plantation seeds February next year.Deciduous tree, grow extremely rapid, 0.5 meter of mean annual precipitation, and the height of tree can reach 15-30 meters, and the hat width is 2/3 of plant height.Leaves in Summer is bright bottle green, has autumn red, yellow, purple polychrome to mix.Inferior hot humid climate seeds.Happiness illumination, growth better on humidity, well-drained subacidity soil.Strong adaptability, anti-part is shaded, the dark wind resistance of root, the sprouting ability is strong.Strong adaptability, but best with the little sour soil earth of fertile viscosity of fertile, moist, Alluvial clay and rivers bottom.Be planted in the mountainous region and hills area performance is preferably all arranged.Blade is long, and fallen leaves are late, leaf 5-7 palmates row.Happiness light, happiness are deep, moistening, acidity and neutral soil, and anti-pollution not, full sun, anti-part is shaded, the dark wind resistance of root, fire-resistant burning, germination is strong, can plant with other tall and big trees groups, also can be as barrier or hedge in large-scale gardens.Because its growth is rapid, outward appearance is attractive, and the flower type is unique, is that one of tree is viewed and admired in the flower garden of commonly using.Late fall or early spring, Li planted, and needed the slow seedling of long period.Gardens very attractive in appearance, avenue tree planting.
The time that need to grow due to the seedling growth of routine, and survival rate is low, is difficult to meet the quality requirement in present domestic afforestation project market.
Summary of the invention
Goal of the invention: the implantation methods that the purpose of this invention is to provide a kind of L. styraciflua, the method is simple, plant percent is high, growth fast, vinasse make matrix that gas permeability preferably is provided, the peat composed of rotten mosses can provide plant growth required trace element soon, and suction rapidly, and other matrix are used in conjunction with, and can keep for a long time the humidity of L. styraciflua.
Technical scheme:, in order addressing the above problem, to the invention provides a kind of implantation methods of L. styraciflua, to comprise the following steps:
1) seed treatment: select winter superior in quality seed to refrigerate immediately, Second Year February, seed is taken out with the ethanol extract immersion of 30.6 ~ 50.8 μ g/ml ursolic acid 1 ~ 2 hour, then leach, rinse well with clear water, dry stand-by;
2) vernalization is processed: prepare the husky bed of vernalization, and husky bedside 1m, dark 20cm, long 2m, be paved into the thick bed surface of 16cm with the yellow sand that the ethanol extract through ursolic acid soaked, and the seed that step 1) is dried is sowed at bed surface, 0.1 ~ 0.2 kilogram every square metre;
3) preparation of matrix and container: with the peat composed of rotten mosses 40%, sandy loam 40%,, vinasse 10%, perlite 7%, superphosphate 2%, import composite fertilizer 1% change in cultivating container;
4) the bud seedling growth bud seedling transplanting: in step 2) 15 ~ 20 days, catch bud seedling stem upwards to mention gently with finger tip, and the bud seedling is implanted in cultivating container;
5) container seedling management: when solar irradiation is stronger, the bud seedling is in time sheltered from heat or light, sprayed 800 times of liquid of Tuzet of 70% every 5 days once, sooner or later water once every day, carry out foliar application once every 5 days palpuses, fertilizer is potassium dihydrogen phosphate and urea, and concentration is 0.4% ~ 0.7%;
6) stock breeding: select fertile soil, the deep nursery lot of soil layer, use sufficient base manure, Transplanted Container-raised Stocks after a year, plant line-spacing are 1.5*1.5 rice;
7) seedlings daily management: daily management mainly contains and loosens the soil, hoes up weeds, liquid manure and the extermination of disease and insect pest.
The management of container seedling in described step 5) also comprises the extermination of disease and insect pest.
In described step 5) and step 7), the extermination of disease and insect pest adopts is that the aqueous solution of 55% phoxim baythion 1:30 squirts tree-walk.
In described step 7), daily management also comprises increases the nutrient management, and described nutrient management also comprises and impose soybean cake and dung polluted water, and the ratio of described soybean cake and dung polluted water is classified 3:2 as.
Beneficial effect: the present invention, with respect to prior art, has the following advantages:
1) this implantation methods is simple, and is scientific and reasonable, produces easily and implements, and easy to use, it is fast that the container stock growing has root growth, and survival rate is high, seedling-slowing stage is short, the innovative characteristicses such as view.
2) matrix of the present invention is drawn materials easily, and the matrix of use is the industrial or agricultural waste products, meets environmental requirement, and this matrix provides sufficient moisture deposit to L. styraciflua, and the nutrition variation is provided.
Embodiment
Below the present invention is further described.
Embodiment 1:
1) seed treatment: select winter superior in quality seed to refrigerate immediately, Second Year February, seed is taken out with the ethanol extract immersion of 30.6 ~ 50.8 μ g/ml ursolic acid 1 ~ 2 hour, then leach, rinse well with clear water, dry stand-by;
2) vernalization is processed: prepare the husky bed of vernalization, and husky bedside 1m, dark 20cm, long 2m, be paved into the thick bed surface of 16cm with the yellow sand that the ethanol extract through ursolic acid soaked, and the seed that step 1) is dried is sowed at bed surface, 0.1 ~ 0.2 kilogram every square metre;
3) preparation of matrix and container: with the peat composed of rotten mosses 40%, sandy loam 40%,, vinasse 10%, perlite 7%, superphosphate 2%, import composite fertilizer 1% change in cultivating container;
4) the bud seedling growth bud seedling transplanting: in step 2) 15 ~ 20 days, catch bud seedling stem upwards to mention gently with finger tip, and the bud seedling is implanted in cultivating container;
5) container seedling management: when solar irradiation is stronger, the bud seedling is in time sheltered from heat or light, sprayed 800 times of liquid of Tuzet of 70% every 5 days once, sooner or later water once every day, carry out foliar application once every 5 days palpuses, fertilizer is potassium dihydrogen phosphate and urea, and concentration is 0.4% ~ 0.7%;
6) stock breeding: select fertile soil, the deep nursery lot of soil layer, use sufficient base manure, Transplanted Container-raised Stocks after a year, plant line-spacing are 1.5*1.5 rice;
7) seedlings daily management: daily management mainly contains and loosens the soil, hoes up weeds, liquid manure and the extermination of disease and insect pest.
The management of container seedling in described step 5) also comprises the extermination of disease and insect pest.
In described step 5) and step 7), the extermination of disease and insect pest adopts is that the aqueous solution of 55% phoxim baythion 1:30 squirts tree-walk.
In described step 7), daily management also comprises increases the nutrient management, and described nutrient management also comprises and impose soybean cake and dung polluted water, and the ratio of described soybean cake and dung polluted water is classified 3:2 as.
The growth rate of this L. styraciflua is that year increment is 1m ~ 1.2m, and 5 years can degree of growing tall be 60cm ~ 75cm, and the life-span is about 100 years.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
