Description

A kind of culture substrate for alpine azalea

Technical field

The present invention relates to the alpine rose culture technique, particularly relate to the cultivation matrix of alpine rose.

Background technology

Alpine rose is meant and is distributed in the high mountain of height above sea level more than 800 meters, the monkeyhead rhododendron leaf kind in inferior high mountain region, its leaf is a keratin, inflorescence mostly is total shape umbel, the corolla diameter can reach 25cm, and petal is glittering and translucent, and furthermore its blade is evergreen glossy, therefore has high sight, not only can do high-grade potted flower, also be high-grade afforestation material.Alpine rose is subjected to people's welcome very much on the flowers market, but because the alpine rose kind of domestic shortage tool independent intellectual property right and ripe culture technique, so the supply of finished product flower is limited, in the market the alpine rose that mostly is import of Xiao Shouing.

Summary of the invention

The objective of the invention is to overcome above-mentioned prior art deficiency, invent a kind of cultivation matrix of suitable alpine rose growth.

The technical scheme of culture substrate for alpine azalea of the present invention is: contain: crop stalk and azalea class mycorhiza bacterium after mushroom slag, pine needle and the pulverizing, and adopt following method step preparation:

1) prepares the organic matter become thoroughly decomposed: Yunnan one with common mushroom slag, pine needle and the crop stalk after pulverizing etc., after stirring, is stacked earlier in the open, Deng descending behind one or two saturating rain or watered to make it drenched, with its tight plastic foil of coveing with, the heap first half of the year or longer time, it is become thoroughly decomposed again;

2) mixing of base starting material: the organic matter that will become thoroughly decomposed: vermiculite: the volume ratio of peat soil=2: 2: 1 is evenly mixed;

3) the pH value is regulated: after matrix was mixed, the copperas solution with 1% was regulated the pH value;

4) in the basic matrix for preparing, add azalea class mycorhiza bacterium.

Described matrix is mixed with azalea class mycorhiza bacterium, and its pH value is 5.0-6.5.

One, the basic matrix preparation program of the present invention is as follows:

(1) prepare the organic matter become thoroughly decomposed: with Yunnan one with common mushroom slag, pine needle and the crop stalk after pulverizing etc., after stirring, open-air earlier the stacking, Deng (or water make its drenched) after descending one or two saturating rain, again with its tight plastic foil of coveing with, the heap first half of the year or longer time, it is become thoroughly decomposed.Through the organic matter of this processing, because of under the big sun, tanning by the sun, add plastic foil and cover the back completely by the high temperature that fermentation itself is produced, it has been played the effect of good fumigation, and the degree height that becomes thoroughly decomposed, organic loose even.

(2) mixing of base starting material: the organic matter that will become thoroughly decomposed: vermiculite: peat soil=2: 2: 1 (volume ratio) evenly mixes.

(3) pH value is regulated: after matrix was mixed, the copperas solution with 1% was transferred to its pH value about 5.0-6.5.

Two, in the basic matrix for preparing, add azalea class mycorhiza bacterium

The existing root system of discovering azalea class plant can with some soil fungi symbiosis, form the symbiont of tool characteristic feature, be referred to as azalea class mycorhiza bacterium.The mycorhiza of azalea can help the azalea root system to obtain its required nutriment, the organic nitrogen source that activation is complicated, and promote root system to organic and absorption inorganic nitrogen, can also alleviate environment-stress, be increased under the alkaline environment, azalea is to the absorption of iron ion and calcium ion.The symbiosis fungi that therefore if can add the azalea class in basic matrix can significantly promote the upgrowth situation of alpine rose undoubtedly.

There are not at present the microbial inoculum or the bacterial manure of suitable azalea growth on market, to sell as yet.But in practice, we find, if collect the part alpine rose under former habitat the rhizosphere humus layer or broken of alpine rose, then it is incorporated in the basic matrix, then will to compare photograph (only containing basic matrix) good in the growth of alpine rose.Therefore think to mix and contain azalea parasymbiosis bacterium in the material, and these fungies can breed fast, infect the basic matrix that does not contain the mycorhiza bacterium, thereby form the mycorhiza structure, finally show the characteristic that promotes the alpine rose growth with the alpine rose root system.

It is one of key that improves the alpine rose culture technique that the present invention selects suitable cultivation matrix.Our company was devoted to develop the industrialization cultivation of alpine rose in recent years always.To in constantly the groping of culture technique, invented a kind of cultivation matrix that is suitable for the alpine rose growth.

The research of alpine rose mycorhiza of the present invention and mycorhiza bacterium belongs to the comparatively scientific research in forward position.Present technique has been avoided probing into azalea mycorhiza bacterial classification class and infection processs, contain medium of azalea class mycorhiza bacterium and the quick procreation of fungi self and utilize, thereby basic matrix has been become contain the matrix of azalea class mycorhiza bacterium, finally play the effect that promotes the alpine rose growth.In case and matrix is infected by fungal component, can become the supplier of " female bacterium " again.This method is simple, and but the growth to alpine rose benefits.

Facts have proved, the alpine rose growth substrate pH value that the technology of the present invention provided is suitable, humus is abundant, ventilative water permeability is good, and decompose humus and make its fertility long owing to the symbiosis fungi that the azalea class is arranged, not only meet the principle that alpine rose requires thin fertile duty to execute, also reduced using to inorganic fertilizer, meet environmental protection, requirements of saving energy, a kind of culture substrate for alpine azalea preferably of therefore can yet be regarded as.
