Cultivation of Mushrooms "Five Changes" May Increase Production
Widening bag cultivation is narrow-bag cultivation. Many people think that using a 25 cm 50 cm plastic bag tube to cultivate Flammulina is better, but the wide bag is easy to infect the bacteria, and when the bud is small, the fruit body is easy to bend, affect the quality, reach the small handle length, light color, fat Tender quality requirements. Therefore, it is better to use a 17 cm 33 cm plastic bag.
Change autoclave to delay atmospheric pressure sterilization. Flammulina velutipes grows rapidly on the culture materials rich in vitamins B1 and B2, and the number of powdered spores is small. However, vitamin B1 is not heat-resistant and readily decomposes at temperatures above 120 degrees Celsius. Therefore, the culture medium should be sterilized at normal pressure. However, in order to ensure the pure bacteria rate, the sterilization time can be extended from 10-12 hours to 13-18 hours.
Change the traditional vertical mushroom to two horizontal headings. When loading, inoculate two tubes and leave about 15 centimeters of tube membrane. Lightly press and tightly close the bag. Horizontal display of four layers of bacteria. This method can ensure the quality of mushrooms, but also can save the mushroom room area, can increase the output per square meter of mushroom house more than 30%.
One-time bag removal is the control solution bag. Two-headed, closed-end bacteria culture, because the oxygen concentration in the bag is low, if the hyphae grow into yellow beads when they are spun out according to the conventional method, the bags will be undoubtedly affected. Therefore, once the growth of the mycelium in the bag is found to be slow, it is necessary to remove the bag in time. But at this time, do not all open until the mushroom handle grows to about 8 cm and then straighten the tube bag once again to ensure the proper temperature, humidity and carbon dioxide concentration in the mushrooming process. In this process, the mushroom body should be prevented from being forced to bend and grow.
Releasing any mushroom stalks to growth is induced by red light. The golden mushroom body has a strong phototaxis, so after the good bacteria is put on the shelf, a 15 watt red light bulb can be hoisted about every 4 meters above the center of the two rows of walls to generate vertical light, which can induce the beam to be directed toward the light source. , to promote mushroom body extension. However, the doors and windows should be shaded so as to prevent the mushroom body from being disordered, lodging and bending.
Organic grape seed extract is, as the name implies, extracted from the high-quality organic grape seed. We use an organic extraction solvent, which is extracted in strict accordance with the EU and USDA organic processing specifications. High content OPC extract is not added with any carrier, such as OPC 95% and OPC 98%. The Grape Seed Extract powder is rich in Oligomers Procyanodolic Complexes (OPC), which is a powerful antioxidant. In addition to the ultra-rich potency of over 20 times higher than Vitamin C, it is also 50 times better than Vitamin E. It helps to strengthen the immune system, and also slow down the aging process, which is of very high market value.
