Abstract

The invention relates to the technical field of rice shrimp aquaculture and discloses an aquaculture method for rice shrimps. According to the aquaculture method for rice shrimps, farming of langoustine can loosen the soil and kill pest; the rice can absorb nutrient elements in the water body and plays the role of shade, which not only purify the aquaculture water body, but also provide habitats and hiding places and therefore good growing environment for langoustine is created and the quality of langoustine is increased; the metabolism products of the langoustine provides organic fertilizer for paddy rice so as to reduce the usage of chemical fertilizer and pesticide during the rice planting process; the space of paddy rice field is effectively utilized; by means of the aquaculture methodof the invention, the langoustine grows fast and has normal sizes; the normal production of rice is not affected; the field is used for two purposes, which greatly increases income.

Description

technical field [0001] The invention relates to the technical field of rice and shrimp cultivation, in particular to a method for cultivating rice and shrimp. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originated in China, rice was planted in the Yangtze River Basin of China 7,000 years ago. Rice in the broad sense is different from upland rice; rice in the narrow sense refers to fresh rice, which is different from seawater rice. and non-glutinous rice. There are other classifications, rice is generally cultivated in paddy fields, and water rice is cultivated without soil. Rice is generally less than one meter high, and the one about 2 meters is a newly cultivated giant rice. Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice". The fruit of rice is rice paddy, which is called brown rice af...
