Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] see figure 1 , the embodiment of the present invention includes:

[0019] A method for raising fish in a novel paddy field, comprising the following steps:

[0020] (1) Field preparation: Select a tidal soil field with sufficient water source, convenient drainage and irrigation, strong water and fertility retention, and evenly spread 1300-1800 kg of retting, fermented and decomposed farmyard manure per mu on the field, and then deep plow the land;

[0021] (2) Field improvement: build ridges around the field after fertilization and deep plowing, compact and increase the height of the field ridge 1 to a height of 40-50 cm. 60cm fish-block...

Abstract

The invention discloses a novel method for fish culture in a rice field. The method includes the following steps of (1) field preparation, (2) field transformation, (3) rice cultivation, (4) fry stocking and (5) daily management. Through reasonable cultivation and control on stocking density and utilization of absorptive action of the rice field for substances such as nitrogen and phosphorus, pollution level of fish culture water is lowered; meanwhile, fertilizer is supplemented to the rice field to enable rice and fish to benefit from each other, coexist and grow; the method has the advantages of high resource utilization rate, saving in cost, pollution reduction, green and healthy culture and the like; compared with those of a traditional method for fish culture in a rice field, yield and quality of the rice and fish are effectively improved.

Description

technical field [0001] The invention relates to the field of ecological aquaculture, in particular to a method for raising fish in rice fields. Background technique [0002] At present, most of the aquaculture industry adopts artificial pond culture or adopts culture nets and boxes to carry out artificial culture in reservoirs or natural water bodies. As we all know, in the process of aquaculture, a large amount of ammonia, nitrogen, phosphorus and other substances will be produced in the water body due to the excretion of aquatic organisms and the decomposition of residual bait. If these substances are not removed in time, they will pollute the water quality and damage the health of aquatic organisms. Healthy growth, and frequent purification treatment is too expensive. [0003] Rice field fish farming is a three-dimensional farming model that organically combines rice planting and fish farming in the same ecological environment. The feeding and swimming of fish can be us...
