First, the characteristics of straw mushroom The straw mushroom is a grass rot fungus, which is a high-temperature, high-humidity toadstool. The optimum temperature for spore germination was 40°C, and the growth of mycelia was 33～38°C. The space humidity is 85% to 95%, and the cultivation raw materials are usually rice straw and corn straw. The moisture content of the raw material was 75% to 85%, the pH value of the spores was 7.4-7.5, the pH value of the mycelial growth phase was 7.8-8, and the pH value of the fruit body was 5-7. Second, the technical points 1. After the reserve of biogas slurry is out of the pond, it is piled on a high ground and sealed with a plastic membrane to prevent pests from spawning and draining naturally. Fresh straw or corn stalks with no mold and rotten will be twisted into a rope-like grassy handle. About 0.7 kg in weight, soaked in water for 1 hour before cultivation, fully absorbed enough water. 2 sowing time is not the same as the temperature, 5 to September custom. 3. Open-air cultivation Choose a place with plenty of sunshine, cool air, and close to the water source. Use loose, organic-rich sandy loam soil and biogas residue to mix and mix for planting straw mushroom noodles. Generally, the lotus root is 1 meter wide and 10 meters long. The earth was dug up on sunny days, crushed after drying, sprayed with 10% lime water and biogas slurry to drive out earthworms and other pests. Two days later, a gap of 1 meter in width and 30 centimeters in depth was opened between the pupae and the pupae for aisles and drainage. Then, the water-absorbing grasses were horizontally arranged on the surface of the pod, with the heads pointing inwards and the base ends outwards, closely aligned and aligned. Place a layer on the foot, and use 1% ammonium sulfate to spray, then sprinkle a layer of biogas residue, put a layer of bacteria species, the first layer with 3 bottles, in turn overlap 2-3 layers, each inward contraction 6 ~ 7 cm, forming a trapezoid, after the third layer is stacked and then spread the bacteria. A group of grass common strains of about 10 bottles of biogas residue used about 25%, and finally in the haystack above and around straw or plastic film, to prevent wind and rain, heat, moisture, to avoid direct light. After 4 days, step on the water and cover the top with soil. Let the natural temperature at 24°C and the air humidity above 80% outdoor, and the temperature above 30°C. Under conditions with more than 60% water in the haystack, mushrooms can be seen within 10 to 15 days. 4. The indoor cultivation of its stacking sowing film, etc., as before, management should pay attention to the room temperature maintained at 25 °C above, the temperature within the haystack experienced a low to high, then high to low process, heap temperature in the tread pile After 4 to 5 days, it can rise to 50 to 60°C. After 2 to 3 days, it begins to decline. When it falls to 42°C, it begins to mushroom. If the stack temperature rises slowly, it will not reach 50°C until the 4th to the 5th day, and it will be stepped on the water (if the grass is very wet, only water will not be used). At the same time, the straw can be thickened or covered with a plastic film. If the temperature of the stack is too high, the straw curtain should be opened to ventilate heat. The indoor cultivation humidity should be controlled at about 90%. If the climate is dry, it can be watered on the haystack, or sprayed with sprayer to spray water, and keep the moisture content of the haystack at 65% to 70% (ie, from the heap The straw pulled out, squeezed by hand to overflow but not drip water). In case of continuous high temperature and sunny days, step on watering once again on the 4th day after being piled. When there is a small white spot on the heap surface, moisturizing is the main method, light spray or less water spray. With the increase of bacterial mines, the amount of water spray is gradually increased. After harvesting, the moisture content of the haystack should be increased. Third, pay attention to matters 1. Can not use the bottom of the biogas residue, so as to avoid hatching undead eggs, contaminated mushroom bed. 2. After sowing for 2 days, the material temperature will rise sharply, the upper layer up to 50 °C, the lower layer up to 45 °C, then pay attention to lift the film ventilation and ventilation 10 to 20 minutes, then cover film, material temperature should be controlled at 32 ~ 38 °C So as not to burn the hyphae when the temperature of the heap is too high. 3. Although straw mushrooms are like wet, but not more than 90%, if the humidity is not enough, you can spray water at 10 o'clock on sunny days and 3 o'clock at 3 o'clock in the morning, or spray dry water. When spraying, be light and do not spill water. Outdoor cultivation in rainy weather should be covered with plastic film, timely removal of film after the rain, whether indoor or outdoor cultivation, we must see the material surface when most of the emergence of small Lei can uncover the film. 4. The abstract is timely. When fruiting bodies, such as eggs, are full and smooth, with a slightly dark brown color, picking is best at this time and harvesting cannot be done too early and too late. 5. Pay attention to pest and disease prevention. Miscellaneous mushrooms that are harmful to straw mushroom are often found in high humidity and poor ventilation. If they occur, they should be dug in time, and 75% alcohol cotton balls can also be used to wipe off mold. Rodenticide can not be poisoned with drugs, such as insect pests, can be used 0.2% to 0.3% of the dichlorvos cotton balls, but also can be properly stopped, let the mushroom bed dry, so that young pests died due to water shortage.
Reflective yarns are woven directly into ribbon, trim, piping, laces, cords and fabrics to achieve a wide range of reflective patterns.
A new knitting, weaving, and crochet yarn will literally light up your life. Reflective Yarn is used as a carry-along fiber to add light-reflecting properties to any project. As a matte-gray color, it blends neutrally into other yarns.
However, with a camera flash or a car light, your design becomes luminously lit, adding an element of fun and flash.
The new yarn nevertheless provides light without weight and a 3-D effect without altering the aesthetic look of a design.
