Background technology
The point disk seedling growing of vegetables and flowers is selected seminal propagation mostly, and offspring's individuality is prone to proterties to be separated and difference.Therefore, tea tree multiselect open country vegetative propagation.Inconvenience band soil when the open country vegetative propagation is transplanted, root system damages heavier, has a strong impact on the survival rate of transplanting, and point disk seedling growing is combined with the tea tree vegetative propagation, cultivate that proterties is consistent, richness is with nutrient matrix, tea shoot that root system is complete, greatly improved the tea shoot transplanting survival rate.
The tea tree point disk seedling growing is Intensive seedling breeding, is convenient to standardized management, has also saved the place of growing seedlings simultaneously, has saved manpower and materials, and compare with conventional seedbed system: the matrix water retention capacity is strong, and root sticks together and is difficult for faling apart, suitable long distance transportation; The resistance of seedling strengthens, and is difficult for hindering root during field planting, almost there is no seedling-slowing stage; Can mechanization transplanting, the transplanting rate improves 4-5 doubly; Shorten growing-seedling period, improve the tea shoot survival rate and accelerate the tea shoot growth, effectively pre-preventing disease and pest; It is shaped neat that the merit that keeps the tea tree female parent, the tea shoot of cultivating become, and is convenient to realize the tea garden management entire mechanization.Matrix used exists the problem that cuttage survival rate is low and the transplanting seedling-slowing stage is grown at present.
Summary of the invention
For adopting the problem that the matrix cuttage survival rate is low and the transplanting seedling-slowing stage is grown in prior art, the invention provides a kind of matrix of suitable tea tree point disk seedling growing.
The object of the present invention is achieved like this: a kind of tea tree plug seedling substrate is mixed by tea grounds, the peat composed of rotten mosses, perlite, sand.
Tea grounds, the peat composed of rotten mosses, perlite, sand are counted with volume ratio: tea grounds 40-60, peat composed of rotten mosses 20-40, perlite 5-15, sand 5-15.
Tea grounds, the peat composed of rotten mosses, perlite, sand are counted with volume ratio: tea grounds 45-55, peat composed of rotten mosses 25-35, perlite 8-12, sand 8-12.
Tea grounds, the peat composed of rotten mosses, perlite, sand are counted with volume ratio: tea grounds 50, the peat composed of rotten mosses 30, perlite 10, sand 10.
Described sand is fine sand.
To be particle diameter surpass full weight 85% modulus of fineness greater than the particle of 0.075mm to described fine sand is 2.2 ~ 1.6.
Tea tree plug seedling substrate provided by the invention can promote the growth of tea shoot root system, improves the tea cutting survival rate of seedling, accelerates the growth rate of tea shoot, significantly improves the tea shoot survival rate.The tea shoot proterties of cultivating is consistent, root system is complete, robust growth, nutrient matrix are abundant.

In above-described embodiment, sand is selected fine sand, and namely particle diameter is 2.2 ~ 1.6 greater than the particle of 0.075mm over full weight 85% modulus of fineness.
In above-described embodiment, it is residue obtained that tea grounds is that tealeaves brews after filtered juice oven dry, and tealeaves has the organic and inorganic inclusion of many suitable growth of tea plant not to be dissolved out fully after water brews, and is present in tea grounds.Tea grounds is undergone microbial fermentation add in the tea tree plug seedling substrate, can promote growth, and fertilizer efficiency is lasting, growth has obvious facilitation to tea shoot.
The peat composed of rotten mosses is rich in the abundant nutrition composition, for growth of tea plant, facilitation is arranged, and the peat composed of rotten mosses is matrix structure, is beneficial to seedling culture, can greatly improve development quality and the cuttage survival rate of seedling.
Perlite can be improved matrix structure, increases the permeability of matrix, alleviates matrix unit weight, controls fertilizer efficiency and fertile degree.
Fine sand improvement soil structure, the ventilating permeable of increase matrix.Preferred fine sand during use, namely particle diameter is 2.2 ~ 1.6 greater than the particle of 0.075mm over full weight 85% modulus of fineness.
Tea tree plug seedling substrate obtained above first makes matrix have certain gas porosity, and is then wetting, and the 540mm that packs into * 280 mm * 100 mm in 72 square black cave, hole dishes, namely can be used for tea cutting and grow seedlings.The cave dish should be sterilized before use, if recycling, the cave dish all need be sterilized before use, avoids tea shoot to infect damage by disease and insect.
Matrix is filled and is wanted neat and consistent in use, to guarantee best taking root and growth result.In the situation that unnecessary matrix is wiped off, the matrix in all holes, cave is roughly suitable.As obviously less in the matrix in some hole, cave, the speed of these cave orifice dryings is just than comparatively fast, thereby can't make Shi Shui reach portfolio effect.
The matrix granule size wants consistent.When using mechanical filling machine, note avoiding the matrix that dallies, otherwise can cause matrix granule too small.Short grained matrix water holding capacity and gas permeability are not good, affect the tea shoot growth.
Matrix should not exceed the hole, cave, can not push the matrix in the hole, cave.Will correctly gently scrape the cave dish matrix in the hole, cave is sunk, but not compress, avoid in the cuttage process, matrix is too hard, and cuttage seeding is difficult to cuttage; The gas permeability of matrix also is difficult to guarantee simultaneously.
The cave dish of filling in matrix is not stacked together.Cave dish stacks and can produce squeezing action to matrix, below the matrix of cave dish can be more closely knit than top, affect gas permeability.In addition, matrix is filled difficult in advance too of a specified duration, if need sabot in advance, needs to wrap with plastics, prevents water loss.
