Rice field shrimps serve two purposes

“I really didn’t expect that the crayfish in paddy fields are not only more ecological and of higher quality, but also more than 300 kilograms of lobster per acre. This year, my 3 acres of paddy fields, only lobsters have already sold two batches of nearly 200 pounds to realize income. More than 4,000 yuan.” On July 29, the author visited Lihua Village, Danlin Township, Jiangyang District, Ganzhou. The old farmer Yang Wengui, who was over sixty years old, was happy to tell the author.

In Yang Wengui's rice fields, I saw that I saw a row of protective gauze standing at the connected ditches outside the paddy field, and there was also an insect removal lamp next to it. Yang Wengui said that this year he started the “shrimp and rice co-cultivation” under the guidance of a youth who had returned to his hometown in the village. The so-called "shrimp and rice co-cultivation" is to cultivate crayfish and grow rice in the same paddy field. At the beginning of this year, he saw the 'shrimp and rice co-feeding' model after returning to his hometown of youth Xu Jiang, and he felt that it was still good. In March, he began to introduce stocking in 3 acres of paddy field, and strictly follow the requirements.

During the planting period, Yang Wengui also had concerns that he feared that the lobster would pinch the seedlings to reduce rice production, and he feared that the survival rate of lobster was not high. He slowly explored under the guidance of Xu Jiang and gradually solved a variety of problems. More and more lobsters were stocked and the survival rate was getting higher and higher. “The booming production of crayfish is the golden age for rice growth, and crayfish can be cultivated all year round, which can add more income than rice.” Yang Wengui said.

During the breeding period, Yang Wengui conducted an experimental comparison of rice fields with "shrimp and rice" and ordinary rice fields, and found that the former rice grows better than ordinary paddy fields. "It is forbidden to abuse pesticides and chemical fertilizers in shrimp and rice co-cultivation fields. Only the use of biological pesticides and pollution-free pesticides can ensure the normal growth of crayfish, and the microorganisms and pests produced during rice growth provide sufficient development for crayfish. The diet of crawfish and the excrement of crayfish provide good biological fertilizer for rice growth. In this complementary biological chain, the quality of crayfish and rice are guaranteed.” He said, “Shrimp and rice co-culture” Can save the cost of pesticides, crayfish bait is corn flour, relatively simple and low cost. "It is only necessary to pour lime water every two weeks. If conditions permit, we must change the water every month." Yang Wengui said.

Yang Wengui also told the author that this year, he tried to plant 3 acres of field blocks just to get started. Next year, he will use 8 acres of rice fields in his family to use "shrimp and rice for a total of" to expand the scale and achieve "one water and two uses." One place double income."
