Fish scales shake to "turn" into fertilizer
At present, a new type of high-quality organic fertilizer, fish scale fertilizer, is being respected by many fruit growers in Fujian and Guangdong provinces. The product was pioneered by a woman from Chishiwan Village, Meiling Town, Zhaoan County, Fujian Province. Over the past two years, she has processed the recovered fish scales into fish scale fertilizer, which has not only opened up the source of agricultural fertilizer, reduced the environmental pollution of waste fish scales, but also increased personal income.
Zhaoan Bay is one of the excellent fishing grounds in Fujian Province, in which Jinjiang and local light boats trade more than 30,000 tons of fresh fish in Gongkou Port every year. There are more than 40 fish processing plants around the port, and they often struggle to deal with the large amount of scales left over from the processing of fresh fish. When the waste fish scales accumulate, they will stink, pour them into the sea and pollute the environment. The masses have great opinions about this, so they have to hire someone to move it to a remote place. A woman in Chi Shiwan Village, who suffered from it, heard that fish scales are high-quality fertilizers for litchi, citrus and other fruit trees and can be developed and utilized. As a result, she organized five villagers to buy fish scales everywhere and process them into fish scales. Fruit growers in Guangdong first bought more than 30 tons of fish scale fertilizer, and the effect of fertilization was very good. The fruit trees grew vigorously, had luxuriant branches and leaves, and had a high fruiting rate, and then ordered another 50 tons from them. By the end of October this year, they had processed more than 180 tons of fish scale fertilizer, which sold well and increased their income by more than 30,000 yuan.
At present, fruit growers from Fujian and Guangdong provinces have come to order fish scale fertilizer from her.
