Abstract

The invention relates to a method for fish inter-culture in a lotus field. The method comprises the following steps of 1, lotus field preparation, wherein a proper paddy field is selected, and a ridge is widened and heightened; a fish pit is formed nearby a water outlet of the lotus field; a 1.5-2 m wide and 0.8 m deep fish ditch around the field is formed at the portion, 1-2 m away from the lotus field, and the fish ditch is communicated with the water inlet and outlet and the fish pit; a filter device and a fish corral are installed at the water inlet and outlet; 2, lotus root culture, wherein in each March and April, lotus seeds are planted when the temperature reaches 15 DEG C; 3, fingerling stocking, wherein in the middle and last ten days of each May, fingerlings with the stocking size being 20-50 g per mu and the density being 200-300 per mu when the water temperature is appropriate, wherein carp accounts for 50%, megalobrama amblycephala accounts for 30% and crucian and black carp account for 20%. The lotus field is used for culturing fish, natural resources of the lotus field can be sufficiently utilized, three-dimensional production can be performed, the purpose of harvesting both lotus roots and fish can be achieved, and good economic and social benefits are achieved.

Problems solved by technology

The ones that mainly produce lotus roots are called Oulian, which have few flowers; the ones that mainly produce lotus seeds are called Zilian, which have dense blooms, but their ornamental value is not as good as that of Hualian; Most of the males and females of the species are vesicular or petalized, and often cannot be fruited

[0004] At present, the lotus is mainly cultivated alone in the lotus field, and the natural resources of the lotus field are not fully utilized, and the economic benefits need to be further improved
