Mushroom cultivation how to control bacterial contamination

Mushroom cultivation of the main bacteria are green Trichoderma, Qu Jian, etc., is the production of seeds and clinker production of one of the most common cultivars. This type of fungal high temperature, moist environment, such as Trichoderma held in long-term survival in the soil and organic materials or shed wall gap, through the air, earth covering materials, tools and other spread.

1. Preventive measures are: use all diseases to completely eliminate the mushroom shed; hair Yin and mushroom every 5 days during spraying a bactericidal drug, the production of disease can be used without a trace and mushroom kill disease spirit alternately.

2. Defiled mushroom sheds have been opened, all ventilation openings have been opened, and the import and export have been enhanced to provide ventilation; at the same time, all diseases have been sprayed without a trace, and then the contaminated bacteria bags have been treated.

3. For spotted contamination: take 100 times the killing solution to eliminate the mold, such as the germination of the fungus spores from the base to raise the concentration to about 50 times, and deep insertion of the needle, so that the liquid from the inside out The killing effect can reach 100%. Note that the needle insertion point should be located diagonally above the contamination point, inserted diagonally and injected to make the contamination point near the ground.

4. Spotting pollution: You can also take the method of injection of drugs, but you should increase the amount of drug, method ibid.

5. Contiguous pollution: When it is difficult to inject drugs, the plastic film at the pollution site can be cut open at the intersection, and the plastic film can be opened and the liquid can be applied. This only adapts to the germs that germinate on the surface of the base material and must be discovered early. Otherwise, the powder can be sprinkled and then the plastic film can be returned to place. The killing effect is good.

6. About 50 percent contamination of bacteria bags: Flexible treatment depending on the situation. For example, edible mushroom seedlings have already reached more than half, that is, the base material has been connected with mycelium, and the plastic bags can be removed. The solution of the king should be immersed in the fungus and then covered with a plastic film to be cultured; if the pollution is heavy and the number of edible fungi is small, 3 to 5 ports can be cut longitudinally in the bag and loosened after the plastic film is immersed. A little longer, then let it settle.

7. If there is a large area of ​​pollution, the pollution time exceeds 15 days, and the contaminated bacteria bags account for about 70 percent of the time, then the batch of bacteria bags will have almost no reserve value. After the bacteria bags are completely cleared out of the shed, there are two methods of treatment. : 1. Set up a awning, after the normal killing treatment, the uncontaminated or less contaminated bacteria bags will be treated as above and placed in the shed to grow bacteria, will lose the direct cultivation of valuable value; 2. The pollution bag is poured, and when the weather is fine, fine lime powder is added at 2% of the weight of the dry material, and is mixed and dried after being used as a clinker cultivation or fermentation material.

8. After clearing the greenhouse, thoroughly clean the sanitation, spray 2 times in a row for 2 days to remove all traces of disease, and remove the coverings such as grasshoppers, close all the ventilation holes and the import and export, and put them in a boring treatment. After about 3 days high temperature Straw shed, you can achieve a better effect of killing bacteria; then you can re-bag culture.


Microcirculation Microscope:

The micro circulation also has the self- adjustment to entrust with heavy responsibility the function. The adjustment divides into the stable adjustment and the strain adjustment, the stable adjustment is for guarantee whole body or main organ circulation blood quantity and blood current capacity relatively constant, and the maintenance blood pressure is relatively stable. The strain adjustment is for adapt organizes the organ the need, adjusts the blood to fill the current capacity. The adjustment is for maintain the whole body circulation`s stability, adapts the whole body or the important organ temporary change need. In order to guarantee the vital activity, essential maintains the whole body circulation to stabilize and to guarantee the whole body or the important organ temporary change needs, only has promptly suitably changes the cardiovascular system, the general circulation function and correspondingly changes the whole body and the partial organs micro circulation condition can meet the above needs. The micro cycle control significance lies in maintains the whole body circulation`s stability, guaranteed the temporary cyclical fluctuation the need, more importantly maintains the partial organization, the cellular substance exchange stability, guaranteed the metabolism temporary change the need, these adjustments basic significances lie in the maintenance vital activity smoothly to carry on.

The Nailfold Capillaroscopy Microcirculation Microscope is an advance medical photoelectric apparatus,equipped with built in special LED light source,used mainly in observation on human nail fold capillary microcirculation or term as video Nailfold capillaroscopy,Such as capillary blood flow, abnormal microcirculation of the vascular structure, cell adhesion, through its powerful optical magnification. Undistorted, real time dynamic video streaming via Sony CCD imaging device onto the LCD monitor screen.


Simply insert the finger to the holder below the optical lens apparatus, fine-tune to fix the focal length and uncover the desired images within seconds.Blood capilliary microcirculation microscope is a non-invasive diagnostic tools, which is gaining large credit among physicians of different specialities in for study of skin blood capilliary network.
