Student teaching model for rice field culture

Abstract

The invention discloses a student teaching model for rice field culture. The student teaching model comprises a base, two support plates are symmetrically arranged on the upper end face of the base, top plates are connected to the upper end faces of the two support plates, limiting grooves are formed in the opposite sides of the support plates, a teaching model mechanism is arranged between the two top plates, and locking universal wheels are arranged at the lower end of the base. The height of a coaming arranged on the periphery of a rice field model plate is 2cm, net covers are mounted on awater inlet pipe and water inlets, so that the phenomenon that shrimps escape can be effectively prevented, meanwhile, two shrimp storing grooves are excavated on two sides of field ridges, each shrimp storing groove has the length being 20cm, the width being 10cm and the depth being 4cm, therefore, when the shrimps are harvested, after water in grooves is drained through a water outlet, only a small amount of water is left in the shrimp storing grooves, at the time, the shrimps can successively enter connecting cavities from shrimp holes via through holes, and then climb into the shrimp storing grooves at two ends of the connecting cavities, and thus the shrimps are conveniently catched.

Description

technical field [0001] The invention relates to the technical field of paddy field cultivation, in particular to a student teaching model of paddy field cultivation. Background technique [0002] Rice field farming is an ecological farming model that performs a virtuous cycle in the paddy field ecosystem based on the principles of ecological economics. Paddy field farming can harvest a considerable amount of aquatic products under the conditions of saving labor, labor, and bait, and can also be used without increasing investment. Under the circumstances, the rice harvest was increased by more than 10%. [0003] Among them, the symbiotic breeding of rice and shrimp refers to a high-efficiency breeding model for cultivating shrimp seedlings in rice fields. The phenomenon of mutual feeding between shrimps occurs, resulting in a relatively low survival rate of shrimps, resulting in relatively small yields, and it is difficult to popularize and explain the existing technology, w...

Problems solved by technology

[0005] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: the symbiotic cultivation of rice and shrimp refers to a kind of high-efficiency breeding mode of cultivating shrimp seedlings in the paddy field, but existing rice and shrimp symbiotic cultivation, because shrimp Competing with shrimps for living space and food is fierce, and shrimps often eat each other, resulting in a relatively low survival rate of shrimps, resulting in relatively low yields, and it is difficult for college students to understand the popularization and explanation of existing technologies. Conducive to the promotion of the symbiotic farming model of rice and shrimp
