Device and method for stereoscopic breeding of retooning rice and fish

Abstract

The invention relates to the field of agriculture, in particular to a device and method for stereoscopic breeding of retooning rice and fish. The device for the stereoscopic breeding of the retooningrice and fish comprises a paddy field, a fishpond, a fish ditch and a fish raising container, wherein the sum of the area of the fishpond and the fish ditch does not exceed 10% of the area of the paddy field, and the fish raising container comprises a container body and a fish hole. The device and method for the stereoscopic breeding of the retooning rice and fish have the advantages of not only preventing the fish ditch from collapsing with the fish raising container directly placed in the fishpond, but also allowing the slope of the fishpond to be made small to improve planting area of the paddy field; guaranteeing easy fishing without affecting farming in the coming year as the fish container can be lifted when the paddy field is harvested; not only prolonging the growth period of the fish in paddy field and facilitating the cultivation of good quality commercial fish via the stereoscopic breeding of the retooning rice and fish but also reducing labor input with no need for the fishto be removed during harvesting of the retooning rice in harvest seasons; harvesting one more season of rice; greatly increasing economic benefits of raising fish in the paddy field.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a device and method for three-dimensional planting and breeding of ratooned rice and fish. Background technique [0002] Fish farming in rice fields has a history of thousands of years in our country. Using fish farming in rice fields can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn soil to promote fertilizer decomposition, and create a new environment for rice growth. Good conditions can realize double harvest of rice and fish and increase economic benefits. [0003] Most of the existing rice field fish farming adopts the method of digging deep ditches and fish pits in the rice fields, but in order to prevent the fish pit from collapsing, the slope of the fish pit must be dug very large, which reduces the planting area of ​​the rice field, even so , The fish pit will also collapse after being soaked in water for a long t...

[0003] Most of the existing rice field fish farming adopts the method of digging deep ditches and fish pits in the rice fields, but in order to prevent the fish pit from collapsing, the slope of the fish pit must be dug very large, which reduces the planting area of ​​the rice field, even so , the fish pit will also collapse after being soaked in water for a long time

Another way is to use cement and bricks to build fish pits, so that farming will not be possible in the second year, and at the same time, it will cause damage to the geology of the rice fields.

In addition, there is no protective device in the existing paddy field fish farming, which will cause the fish in the paddy field to be predated by birds, causing economic losses to fa
