Fish scales turned from waste into treasure, processed into fertilizer
Currently, a new type of high-quality organic fertilizer - fish scale fertilizer - is being highly praised by many fruit growers in provinces such as Fujian and Guangdong. This product was first developed by a woman in Chishiwan Village, Meiling Town, Zhao'an County, Fujian Province. Over the past two years, she has processed recovered fish scales into fish scale fertilizer, which has both opened up a source of agricultural fertilizer, reduced environmental pollution from waste fish scales, and increased her personal income.

How to process Schisandra seeds? Detailed explanation of the correct processing method
After the Schisandra fruit ripens and is harvested, select plump, large, disease-free Schisandra fruits, soak them in warm water (40-45°C) for 3 days, rub off the flesh, pick out the seeds, then use water separation to remove the shriveled grains, and store them in a ventilated, dry place. After drying, carry out stratification. The stratification method is to fully mix the prepared seeds with 3 times their mass of wet sand; the sand's moisture level should be such that it does not form a ball when squeezed by hand. Dig a pit trench of 60cm×60cm×60cm, with the seed-and-sand mixture at a thickness of 40cm, cover with 15cm of soil, then cover with a

Introduction to Mushroom Processing Methods and Technical Points
I. Pickled Mushrooms in Soy Sauce 1. Salting the Base: Clean the mushrooms, remove debris, wash and drain them. At a ratio of 10-5 kg of salt per 100 kg, place the mushrooms in brine, just enough to submerge them. Seal and pickle for 1 week, turning them twice during this period so the salt penetrates evenly. 2. Soy Sauce Pickling: Remove the mushrooms and drain off the brine, soak them in clean water for one day, take them out and air-dry, then put them into a soy sauce jar and pickle them in soy sauce at a ratio of 50-70 kg of sweet bean sauce per 100 kg, with the temperature preferably at 20°C. During the soy sauce pickling period, stir once every morning, and after 10 days they can be taken out of the jar. They taste delicious and can be served either as a side dish

Detailed Explanation of Potato Harvesting, Storage and Processing Techniques
I. Timely harvesting. Potatoes intended for storage are best harvested when dry matter accumulation is at its maximum and the tubers are fully mature. Spring potatoes should be harvested in early to mid-June, while autumn potatoes should be harvested in early November and must not be exposed to frost. Whether spring or autumn potatoes, if rain occurs before harvest, harvesting should wait until the soil has dried appropriately. Freshly dug tubers have tender skins and should be left on the ground to air for 1-2 hours, then collected after the potato skin surface has dried slightly. However, they must not be sun-dried for long periods in summer; after harvest they should be promptly stored in a cool, shaded place. During storage, strict selection should be carried out, removing tubers that are diseased, damaged,
