What is the latest cost budget for artificial cultivation of shiitake mushrooms?
Shiitake mushrooms are not only a delicious food, but also have fairly good medicinal value, and are highly favored by consumers. Yuan'an County fully utilizes and leverages its advantage of abundant forestry resources and its long-standing reputation as a “sea of forests”, actively developing shiitake mushroom production and making it a pillar industry for increasing farmers' income. So what exactly are the costs and benefits of cultivating shiitake mushrooms?
1. Culture medium formula (calculated per 10,000 jin of dry material, with bags sized 15x55, about 5,555 tubes)
① Sawdust: 77% 7,700 jin x 0.40 yuan = 3,080 yuan. ② Wheat bran: 15% 1,500 jin x 0.80 yuan = 1,200 yuan. ③ Corn flour: 3% 300 jin x 1.00 yuan = 300 yuan. ④ Gypsum: 2% 200 jin x 0.5 yuan = 100 yuan. ⑤ Superphosphate: 1% 100 jin x 0.3 yuan = 30 yuan. ⑥ Sugar: 1% 100 jin x 2.7 yuan = 270 yuan. ⑦ Salt: 0.1% 1 jin x 1 yuan = 1.00 yuan. ⑧ Magnesium sulfate: 0.1% 10 jin x 1 yuan = 10 yuan. ⑨ Subtotal: 4,991 yuan.
2. Labor wages for tube making
① Mixing worker: 1 person x 60 = 60 yuan (machine mixing). ② Bagging workers: 10 people x 60 = 600 yuan. ③ Sterilization workers: 2 people x 60 = 120 yuan. ④ Unloading workers: 3 people x 60 = 180 yuan. ⑤ Inoculation workers: 8 people x 60 = 480 yuan. ⑥ Odd-job workers: 2 people x 30 = 60 yuan. ⑦ Subtotal: 1,500 yuan.
3. Auxiliary materials
① Mushroom bags: 5,555 pieces x 0.16 = 888.8 yuan. ② Spawn: 200 bags x 2.5 yuan = 500 yuan. ③ Plastic rope: 2.5 jin x 8 yuan = 20 yuan. ④ Aerosol disinfectant: 30 packs x 1 yuan = 30 yuan. ⑤ Lysol: 1 bottle x 8 yuan = 8 yuan. ⑥ Alcohol: 5 bottles x 4 yuan = 20 yuan. ⑦ Sterilization firewood: 3,000 jin x 0.2 = 600 yuan. ⑧ Water and electricity fees: 30 kWh x 0.6 yuan = 18 yuan. ⑨ Subtotal: 2,084.8 yuan.
4. Labor from spawn-running management to mushroom harvesting
Turning the pile: 5 people x 60 = 300 yuan, moving mushroom logs to the field: 3 people x 60 = 180 yuan, removing bags from logs: 1 person x 60 = 60 yuan, log color-turning workers: 5 people x 60 = 300 yuan, mushroom-inducing workers: 2 people x 60 = 120 yuan, mushroom-picking workers: 27 people x 60 = 1,620 yuan. Subtotal: 2,580 yuan.
5. Equipment investment
One grinder 2,400 yuan, one 15-horsepower diesel engine 2,500 yuan, two bagging machines 3,600 yuan (including one 1.5 kW single-phase motor), one sterilization pot 15,000 yuan, one self-propelled mixer 4,500 yuan.
Subtotal: 28,000 yuan (equipment investment amortized over ten years, 2,800 yuan per year). The above total production cost is 13,955.8 yuan, with an average production cost of about 2.52 yuan per log.
6. Output value
① For off-season cultivation, each tube of mushroom log yields 1.3 jin of fresh mushrooms, calculated at 5 yuan per jin of fresh mushrooms: 5,555 tubes x 1.3 jin = 7,221 jin of fresh mushrooms x 5 yuan = 36,105 yuan in output value.
② For autumn, winter and spring mushroom cultivation, each tube of mushroom log yields 1.5 jin of fresh mushrooms. Calculated at 5 yuan per jin of fresh mushrooms: 5,555 tubes x 1.5 jin = 8,332 jin of fresh mushrooms x 5 yuan = 41,660 yuan in output value.
