Ecological rice, turtle and shrimp planting and breeding method

Abstract

The invention discloses an ecological rice, turtle and shrimp planting and breeding method. The ecological rice, turtle and shrimp planting and breeding method comprises the following steps of S1, selecting a rice field with sufficient water sources and convenience in irrigation and drainage, forming an annular ditch, and building escape-proof walls around the annular ditch; S2, filling water intothe rice field, detecting the salt content of the water, and controlling the salt content of the water to be lower than 0.5%; S3, putting young soft-shelled turtles according to the quantity of 200-300 young soft-shelled turtles per mu of rice field, and ensuring that three consecutive days are sunny days before putting and the temperature is 25 DEG C or above; S4, putting young shrimps, wherein5000-7000 young prawns are put into each mu of rice field; S5, sowing rice in the last ten-day period of April, and transplanting rice seedlings in the last ten-day period of May; and S6, harvesting the rice in the last ten-day period of October, and catching the soft-shelled turtles and the shrimps in the middle ten-day period of April of the next year. With the adoption of the shrimp and rice planting and breeding method, the field transformation work amount and the input amount are greatly reduced, so that the original water and soil resource ecological environment is basically maintained,and the symbiotic and mutual benefit effect and the purpose of planting the rice and breeding the soft-shelled turtles and the shrimps in the whole field are effectively realized; and meanwhile, fertilizer produced by the soft-shelled turtles and the shrimps can provide nutrients for rice growth.

Description

technical field [0001] The invention relates to the technical field of rice-fishing ecological comprehensive planting and breeding, in particular to an ecological planting and breeding method of rice soft-shelled turtle and shrimp. Background technique [0002] my country is not only the world's largest user of chemical fertilizers, but also the largest user of pesticides. At present, the annual usage is about 1.3 million tons. In some high-yield areas of rice, pesticides are used more than 30 times a year, and the amount per hectare is as high as 300kg, and some even exceed 450kg. The problem of excessive use and low utilization rate (about 30%) is very serious. According to a study by the Chinese Academy of Agricultural Sciences, the excessive use of pesticides in my country has reached 40% in rice production. [0003] At present, the most commonly used breeding method for shrimp and soft-shelled turtles in paddy fields is co-culture of soft-shelled shrimp and soft-shell...

Problems solved by technology

[0003] At present, the most commonly used breeding method for shrimp and soft-shelled turtles in paddy fields is co-cultivation of soft-shelled shrimp and soft-shelled turtles. The most commonly used farming methods for the production of shrimp and soft-shelled turtles are industrial farming, greenhouse farming, and pond farming. The commonality of these farming techniques is that High-density farming, and the resulting consequences are water pollution, the edible quality of the cultured shrimp and soft-shelled turtles is not high, and the survival rate of soft-shelled turtles is not high during ecological farming
