Abstract

The invention discloses a cultivation technology of a high-yield camellia oleifera in spring and autumn, which particularly relates to the technical field of economic forest culture and management and high yield. The traditional planting in spring is changed to the planting technology in two seasons, namely, the spring and the autumn. The cultivation technology comprises the steps: (1) laying off, and digging holes; (2) applying base fertilizer, and back filling; (3) taking and transporting seedlings; (4) planting; (5) watering root setting water; and (6) covering with a mulching film. Camellia oleifera seedlings are dead after being planted in spring due to factors such as weather; by utilizing biological characteristics of the camellia oleifera, a camellia oleifera root system has a sprouting period in autumn, and the camellia oleifera seedlings can be planted (complementarily planted) in autumn, so that the camellia oleifera seedlings are relatively tidy, the survival rate in the year when the camellia oleifera forms a forest, the management difficulty caused by the untidiness of the forest at the later period can be alleviated, and the corresponding forest management cost at the later period can be reduced.

Description

A kind of cultivation technique of high yield oil tea spring and autumn

Technical field

The invention belongs to economic forest camellia oleifera lam planting technology field, be specifically related to the cultivation technique of a kind of high yield oil tea spring and autumn.

Background technology

It is known that traditional camellia oleifera lam plantation is typically carried out in the annual 1-4 month in spring, according to the difference of other Silvicultural Measures, such as the difference of the ancillary method such as land preparation mode, mulch planting, oil tea survival rate is typically at 50-60%.After-culture woods must be carried out in the spring of Second Year, and its shortcoming is that the first survival rate of planting of oil tea is affected bigger by various factors such as weather；And the nursery stock of after-culture and nursery stock then to there is year poor, under equal cultural operations, cause the difference in height of oil tea nursery stock it is obvious that cause the overall forest form of nursery stock irregular.Have a strong impact on production cycle and the product quality of camellia oleifera lam.

Summary of the invention

The invention aims to solve the defect of above-mentioned existence, i.e. overcome the deficiency of background technology, and the cultivation technique of a kind of brand-new oil tea spring and autumn is provided, idea that it breaks traditions and pattern, realize with brand-new method, it mainly forms according to the growth characteristics research experiment of oil tea, and it has the advantage that.

(1) afforestation average survival (85-95%) then is improved.

(2) seedling growth growing way is average, and forest form aligns mutually.

(3) time cost (carry and make the previous year forest form neat, overall growing way is average, and the effect reaching to synchronize for later Forest management creates conditions) of Forest management is reduced.

(4) later stage silviculture and management cost is reduced.

The present invention is realized by following tending technique:

The cultivation technique of a kind of oil tea spring and autumn, it is characterised in that it changes plants as spring and autumn cultivation technique former single spring, its step specific as follows:

(1) setting-out, cave is dug: raise moat breadth of the lift 2-3m at flat ladder, moat width, deep 70*50cm moat in carry out setting-out by the seeding row spacing Calx of 2*3m, centered by sampling point, the cave of 30*30*30cm is excavated again: (2) apply fertilizer to the subsoil: in the cave (30*30*30cm) dug, uniformly execute the fertilizer that 0.5-1kg ferments in the place of setting-out, and at the yellow mud hack of base fertilizer surface tiling thick layer about 5-10cm；(3) seedling taking fortune Seedling: the most overcast and rainy Light media nutritive cup seedlings having taken life in 2 years from nursery, the same day morning upper transplanting, the forest land planted needed for being transported to the same day；(4) plant: again oil tea Seedling is stood in cave, with soil in small, broken bits around cave, seedling root is buried, carry Seedling, compacting, it is ensured that seedling root is unfolded, and makes lower slightly 1-2cm at the 1-2cm of plant center, grafting mouth is tried one's best outside soil, and grafting mouth is tried one's best parallel or slightly higher with the level digging cave；(5) water and determine root water: water the water of 0.2-0.5L the nursery stock planted along root, make root system well contact with the soil of surrounding；(6) covering with ground sheeting: select plastic sheeting, thin film is cut into the square of 50*50cm, and by cornerwise while shearing to cornerwise 4.5: 5.5 points, the thin-film covering cut at the root of oil tea nursery stock, oil tea nursery stock root is made to be positioned at the center of thin film, at the hack that the thin film upper cover last layer completed is fine.

The proportioning of described fertilizer: the nitrogenous fertilizer of 8%, 30% chicken manure become thoroughly decomposed, the oil-tea camellia husks of 35%, the rice husk (or powder of straw minces) of half carbonization of 20%, the black pond sludge after 7% sterilization.

Described selection of time is carried out in the fall, and temperature is less than cloudy day or the rainy day of less than 25 DEG C.

Described Light media nutritive cup seedlings cup footpath >=12cm, cup is high >=10cm.

Degradable polyethylene material thin film selected by described mulch film.

Detailed description of the invention:

nullA kind of oil tea cultivation technique of the present invention，It is to be changed into the planting technology of a kind of oil tea spring and autumn by planting technology in original thousand of years traditional spring，It select camellia oleifera lam plantation then by the end of September to carrying out by the end of October，The temperature cloudy or little rainy day less than 15-25 DEG C is selected to plant，The general nutritive cup seedlings selecting more than a year，Or the bare-root seeding of life in 2 years also may be used，Cave at the local excavation 30*30*30cm just planting the scarce root and stem of certain plants，First backfill the fine earth of 15-20cm，Again oil tea Seedling is stood in cave，Position is buried with cave surrounding soil root seedling root，Propose Seedling compacting and guarantee that seedling root is unfolded，Make lower slightly 1-2cm at the 1-2cm of plant center，Grafting mouth is allowed to try one's best outside earth，Grafting mouth is tried one's best parallel or slightly higher with the horizontal plane digging cave，For the place that some geographical conditions is the most suitable，Need the forest land that soil moved in improve the original is cultivated，Digging cave standard is 50*50*50cm，In planting hole, uniform spreading spills the soil moved in improve the original of thick about 50cm simultaneously，Plant again.
