Pleurotus ostreatus is a kind of edible mushroom with wide cultivation and high yield. In summer, high temperatures and rain, high humidity, and improper management techniques are prone to various pests and diseases. Therefore, the key techniques for the summer cultivation of oyster mushrooms are described below:
1. According to market demand, suitable varieties should firstly be selected medium and high temperature varieties such as Zhongwu No. 10 and No. 1012. The mushrooming temperature range is 8°C to 28°C. High temperature varieties such as West Germany 33 and Yaguang No. 1 etc. The suitable temperature is 14°C-26°C.
2. Facilities Facilities for the cultivation of oyster mushrooms in the summer should be based on cooling. Special awnings or semi-underground mushroom huts must be built to facilitate shading and cooling. In summer, it is also a season of various microbial activities. The odor produced during the growth and development of Pleurotus ostreatus is likely to breed various diseases and insect pests. Therefore, window screens and vents are required to install screens to prevent insects from entering.
3. Cultivation Management Technology
(1) Cultivation with dry clinker. In order to reduce the pollution and increase the yield, the moisture content of the ingredients should be reduced. The moisture content of the ingredients should be controlled at around 58% to 60%. In order to save energy and reduce costs, culture materials can be stacked and fermented for 24 to 48 hours before bagging, and then sterilized at normal pressure for 6 hours.
(2) Increase the inoculation amount. In order to reduce the contamination of bacteria, it is an effective measure to increase the inoculation volume. In the summer clinker cultivation, 20 to 25 inoculation bags (two inoculations) are usually used per cultivar (about 600 g).
(3) sparse code, ventilated bacteria. Fungus bags should not be placed too densely and must not be stacked.
(4) Water spray and ventilation. Ventilate and moisturize in the morning, evening, or night. Use less ventilation and less water during the day.
(5) Ensure the health of the mushroom house. Mushroom house requires dry ground, do not become mud; material surface should be clean, each time after picking mushrooms to clean up the material surface, reduce the contamination of bacteria and pests.
(6) Cooling the cover soil. Covering the soil with mushrooms is an effective way to reduce the temperature in summer, reduce pollution and reduce the occurrence of pests and diseases. The specific approach is to deep-slope the ground, take out the soil, make a plan after the rake, sprinkle a thin layer of lime powder, take off the bag, put the stick flat, cover the 2? 3 cm soil, spray moisture. The air humidity can be maintained at about 80%.
Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (CGMP) - specific phosphodiesterase 5 (PDE5) and an oral drug for the treatment of ED. The physiological mechanism of normal penile erection involves the release of nitric oxide (no) during sexual stimulation. Nitric oxide activates guanylate cyclase in the smooth muscle cells of the corpus cavernosum, which leads to the increase of cGMP level, resulting in the relaxation of the smooth muscle in the corpus cavernosum, the expansion of the cavernous sinus and the inflow of blood. Erectile dysfunction is mainly due to the dysfunction of smooth muscle relaxation of corpus cavernosum. Sildenafil has no direct relaxation effect on human sponges in vitro, but can enhance the effect of nitric oxide by inhibiting the decomposition of cGMP by PDE5 in sponges. Sildenafil can inhibit PDE5, increase cGMP level, relax smooth muscle of corpus cavernosum and let blood flow into corpus cavernosum. Studies have shown that erectile response increases with the increase of dose and plasma concentration, and the efficacy can last for 4 hours (but is weaker than that at 2 hours).
