Shrimp, rice and lotus root combined ecological planting and breeding method

Abstract

The invention provides a shrimp, rice and lotus root combined ecological planting and breeding method which includes the steps of (1) applying a base fertilizer: taking a wormcast organic fertilizer and pig and cattle pen manure as the base fertilizer; (2) digging shrimp ditches before lotus roots are planted, controlling the water level height from the tops of the shrimp ditches to a water surface, planting the lotus roots, when main lotus roots of the lotus roots enter into a primary ripening stage, increasing a water level, interplanting late rice, and putting shrimp seeds 7-10 days after late rice transplanting; (3) during a lotus root seedling stage, performing topdressing for the first time, applying wormcast organic fertilizer and urea in a combined mode, when 5-6 lotus leaves grow out, performing topdressing for the second time, applying the wormcast organic fertilizer and a potassium sulfate type compound fertilizer in a combined mode, and in the mature period of the lotus roots, performing topdressing for the third time, and applying the wormcast organic fertilizer and the urea in a combined mode; and (4) feeding palatable pellet feed obtained by compound fermentation of earthworms to the shrimp ditches at different points. According to the shrimp, rice and lotus root combined ecological planting and breeding method, through more scientific and reasonable fertilizer application, a soil structure, nutrients and water quality of an interplanting field are guaranteed, stable high yield of rice coupling interplanting is achieved, and the survival rate and yield of shrimp culture are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting and breeding, in particular to a combined ecological breeding method for shrimp, rice and lotus root. Background technique [0002] Lotus root is a light-loving aquatic plant. It needs to control a certain water level throughout its growth period, and often needs to apply a lot of fertilizer during the planting process. At present, in order to achieve a higher utilization rate of land, the production technology of rice couple interplanting has gradually appeared. However, in the existing actual production, in order to ensure the high yield of rice and lotus couple, there are often problems of unreasonable fertilizer application and excessive application of chemical fertilizers. Phenomenon, it is easy to cause problems such as land compaction and water environment degradation, which greatly affects the service life cycle of rice-coupled interplanting, resulting in a significant decrea...

Problems solved by technology

At present, in order to achieve a higher utilization rate of land, the production technology of rice couple interplanting has gradually appeared. However, in the existing actual production, in order to ensure the high yield of rice and lotus couple, there are often problems of unreasonable fertilizer application and excessive application of chemical fertilizers. Phenomenon, it is easy to cause problems such as land compaction and water environment degradation, which greatly affects the service life cycle of rice-coupled interplanting fields, resulting in a significant decrease in the output of the next round of crops, and it is difficult to effectively ensure the stable and high yield of rice-coupled interplanting

However, if the soil is loosened frequently, it will easily cause the internode spacing of lotus root planting to be greatly shortened, the skin and flesh will be hard, and the quality will be reduced.

As a result, a breeding model that combines aquatic animals such as shrimps and crabs with rice lotus roots has been proposed, but it is still difficult to achieve effective promotion due to unreasonable feeding of shrimp bait and the impact of fertilizers on shrimp growth.
