Problems solved by technology

[0002] In traditional shrimp-rice co-cropping, in order to provide enough space for shrimp to move, there is a problem that shrimp and rice compete for space. The planting density of rice in shrimp-rice co-cropping is only 67% of the traditional rice planting density, which affects the overall rice yield. , reducing economic benefits
In the process of transforming rice fields in the traditional co-cropping of shrimp and rice, it is generally adopted to excavate a large ring ditch with a depth of 3 to 4 meters and a depth of 1.5 meters, resulting in relatively large engineering costs and increased breeding costs.

Embodiment 1

[0019] The present invention proposes a kind of planting method of novel shrimp rice rotation, comprises the steps:

[0020] S1: First, construct seedling ponds. Before planting, dig a ring ditch with a depth of 1.2m, a bottom width of 3m, and a slope of 35 degrees around the paddy field. The excavated soil is used as a ridge, and the ridge is 0.8m higher than the field surface. , the width of the ridge surface is 2.5m, and then a shallow ditch with a depth of 0.8m, a bottom width of 1.5m and a slope of 45 degrees is dug every 2m on the field surface, and the two ends of the shallow ditch are connected with the surrounding ring ditch;

[0021] S2: For rice planting, before rice planting, the seeds need to be treated. After washing the seeds, soak the seeds with strong chlorine or prochloraz for 10 hours, disinfect and sterilize, which can effectively prevent bacterial blight, rice For blast, rice smut, and base rot, use machine transplanting for rice sowing. Machine transplant...

Embodiment 2

[0032] The present invention proposes a kind of planting method of novel shrimp rice rotation, comprises the steps:

[0033] S1: First, construct seedling ponds. Before planting, dig a ring ditch with a depth of 0.8m, a bottom width of 2m, and a slope of 25 degrees around the paddy field. The excavated soil is used as a ridge, and the ridge is 0.5m higher than the field surface. , the width of the ridge surface is 1.5m, and then a shallow ditch with a depth of 0.5m, a bottom width of 1m and a slope of 30 degrees is dug every 1.5m on the field surface, and the two ends of the shallow ditch are connected with the surrounding ring ditch;

[0034] S2: For rice planting, before rice planting, the seeds need to be treated. After washing the seeds, soak the seeds with strong chlorine or prochloraz for 10 hours, disinfect and sterilize, which can effectively prevent bacterial blight, rice For blast, rice smut, and base rot, use machine transplanting for rice sowing.

Embodiment 3

[0045] The present invention proposes a kind of planting method of novel shrimp rice rotation, comprises the steps:

[0046] S1: First, construct seedling ponds. Before planting, dig a ring ditch with a depth of 1m, a bottom width of 2.5m, and a slope of 30 degrees around the paddy field. The excavated soil is used as a ridge, and the ridge is 0.7m higher than the field surface. , the width of the ridge surface is 2m, and then a shallow ditch with a depth of 0.7m, a bottom width of 1.2m and a slope of 40 degrees is dug every 1.7m on the field surface, and the two ends of the shallow ditch are connected with the surrounding ring ditch;

[0047] S2: For rice planting, before rice planting, the seeds need to be treated. After washing the seeds, soak the seeds with strong chlorine or prochloraz for 10 hours, disinfect and sterilize, which can effectively prevent bacterial blight, rice For blast, rice smut, and base rot, use machine transplanting for rice sowing.

Abstract

The invention discloses a novel crawfish-rice rotation culturing method. The novel crawfish-rice rotation culturing method comprises the following steps of S1, constructing a seedling and seed pond; S2, processing seeds and planting rice; S3, stocking seed crawfish; S4, after elodea nuttallii is germinated and grows out of water, filling in water until reaching an original water level; S5, after 35-50 days of growth, harvesting the rice. The novel crawfish-rice rotation culturing method is improved from a traditional crawfish-rice rotation culturing method and is clear in processes; planting the rice can ensure sufficient nutrients in water, breeding crawfish can purify the water, and the agricultural income can be increased accordingly.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a novel method for planting and raising rice in rotation with shrimp. Background technique [0002] In traditional shrimp-rice co-cropping, in order to provide enough space for shrimp to move, there is a problem that shrimp and rice compete for space. The planting density of rice in shrimp-rice co-cropping is only 67% of the traditional rice planting density, which affects the overall rice yield. , reducing economic benefits. In the process of transforming the paddy field in the traditional shrimp-rice co-cropping, since it is generally adopted to excavate a 3-4 m large ring ditch with a depth of 1.5 m, the project cost is relatively large and the breeding cost is increased. Contents of the invention [0003] The present invention proposes a novel method for planting and cultivating shrimp and rice in rotation, so as to solve the problems raised in the above-mentioned ba...
