Production technology of pollution-free agricultural products Pleurotus eryngii

To establish an edible fungus production base, it is necessary to comprehensively consider the conditions of the atmosphere, soil, water quality, edible fungi cultivation substrate, etc., and formulate a complete and scientific operation procedure, which meets the environmental requirements of the production area of ​​pollution-free edible fungi, and stipulates the field selection required for production. Management methods such as planning and cultivation. This regulation is applicable to the production of Pleurotus eryngii with pollution-free agricultural products (6.81, -0.14, -2.01%) .

　　 1. The environment of the production area is surrounded by forests around the production base, naturally isolated from the agricultural production area, with good ecological environment, excellent water quality, clean and sanitary production site, flat terrain, convenient drainage and drainage, no toxic and harmful gases, no industrial “three wastes” around 10 kilometers, Poultry house, garbage (stool) field, all kinds of sewage and other sources of pollution, and away from hospitals, schools, residential areas, more than 500m from the highway , is very suitable for the production and management of edible fungi.

    2. Reasonable layout of the production site The production area should be reasonably arranged, and the production area and the living area should be strictly separated. The production area, seed production, bacteria and mushroom area should be connected reasonably. The raw material warehouse should be kept at a certain distance from the mixing, packaging, sterilization, cooling and inoculation areas. The inoculation room and the cultivation room should be isolated from the cultivation field, and the surrounding environment should be clean and tidy. In the mushroom house, the contaminated material surface on the bacteria package should be cleaned up in time and buried or burned to avoid spreading. It should be prevented from adversely affecting the surrounding environment due to fermentation and waste disposal of mushroom culture materials.

　　 3 , production technology measures

    Pleurotus eryngii cultivation season: The temperature of Pleurotus eryngii mushroom is 10 ~ 20 °C, which is suitable for cultivation in late autumn and late spring in our county. 10 - 11 Yuefen do bacteria package, late Month - March fruiting. Raw material formula: cottonseed shell 34% , wood chips 34% , bran 20% , corn flour 8% , gypsum powder 1% , brown sugar 1% , lime powder 2% .

Preparation of the bacteria bag: using polypropylene bag with the specification of 12X × 60cm × 0.05cm , mixing the culture materials, mixing the water content from 65% to 70% , and the pH value is 6.5 to 7.5 (the optimum pH value is 5.5 to 6.5 when the mushroom is produced. ) . After the culture material is bagged, the bag mouth is tightly tied, gently handled, and subjected to atmospheric pressure sterilization. Keep at 100 °C for 12 to 14 hours, sterilize and cool to below 30 °C, inoculate, use bacteria to inoculate bacteria to avoid contamination caused by sweat on the hands, and then store in a cool, dry, clean and ventilated culture room. Silk is usually full of bags for 40 to 50 days. Mushroom management: After the mycelium is full, you can put it on the shelf. The humidity in the cultivation room is maintained at 90% to 95% , which can spray water mist to the space and the ground. Generally, the mushroom buds can be obtained after 10-15 days. The management method of the mushroom buds adopts the management method of the mushroom, that is, when the small buds appear, the knife film is used to cut the film of the quarters of the small buds, and a quarter of the bag film is left on the tube to protect the mushroom buds. Later, as the mushroom bud grows up, it naturally pulls out the bag film and grows outward. At the same time, pay attention to the inferior and strong stay, and ensure that the mushroom buds left by the sufficient nutrient supply grow robustly. The speed of buds has a great relationship with temperature. The temperature is 12-15 °C, the mushroom buds are more, the mushrooms are neat, and about 15 可 can be harvested; if the temperature is lower than 8 °C, the mushroom buds will not form, even if elongated fruiting body will stop growing, shrinking, until death; temperature exceeded 21 ℃ difficult squaring, will shrink the formed Gulei death, growth Gulei humidity of 85% to 90% is appropriate . When the temperature is high, water can't be sprayed onto the fruiting body, because it will cause yellowing of the mushroom body, causing infection of bacteria and causing rotten mushrooms. The formation and growth of fruiting bodies requires fresh air to ventilate, mushroom buds, high yield, mushroom buds open normally, and the shape of the flower is large. 4 , the harvesting cap is flat, and the spores have not been ejected for a suitable harvest period. A second tide can be harvested in about 15 days. Therefore, it is necessary to harvest in time and sell freshly. Store in the cold storage, the temperature of the warehouse where the product is stored is kept at 2-5 °C. It is strictly forbidden to mix with toxic and odorous items to prevent infection.

 

LED Track Line Lights

What is linear track lighting?

LED Track line lights are commercial track lights, suitable for supermarkets, stores, exhibitions and other places. Combinable with Cob Spotlight, ambient and accent lighting are on the same track for easy installation. And the flexibility is also very strong to move on the track. It is different from other led linear lights in that it is very invisible because it is an LED Linear Light embedded in the track. The light efficiency is 110-130lm/w, Flicker-free driver, THD<15%, the color rendering index can reach up to 97. Compared to other LED Track Lights, this Led Track Linear Light will cost less. So if you are looking for cost-effective and good quality LED Track Lights, you can choose this product.

3. PMMA Linear Track Light with Micro Prismatic Optic: UGR>19 anti-glare, the lens is very beautiful and delicate.

They can match the following brand tracks:
