Biogas slurry high-efficiency water saving system in rice irrigation

Abstract

The invention provides a biogas slurry high-efficiency water saving system in rice irrigation, and relates to the technical field of rice planting. The biogas slurry high-efficiency water saving system in the rice irrigation comprises a water suction pump; one side of the bottom of the water suction pump is fixedly connected with a water suction pipe; a biogas slurry filtering mechanism is mountedat one end of the water suction pipe, which is away from the water suction pump; a first connection pipe is mounted at one side of the bottom of the water suction pump, which is away from the water suction pipe; one end of the first connection pipe, which is away from the water suction pump, is fixedly connected with a secondary filtering mechanism; one end of a second connection pipe, which is away from the second filtering mechanism, is fixedly connected with a valve control mechanism; a flow diversion mechanism is mounted at one end of the valve control mechanism, which is away from the second connection pipe; and one side of the flow diversion mechanism is connected with a fixed point fertilization mechanism. By designing double filtering mechanisms, the valve control mechanism, the flow diversion mechanism and the fixed point fertilization mechanism, fixed point fertilization on rice seedlings can be completed; meanwhile, by multiple stages of flow diversion, water saving efficiency of the system is greatly improved; and the biogas slurry high-efficiency water saving system in the rice irrigation is valuable to greatly popularize.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a high-efficiency biogas slurry water-saving system in rice irrigation. Background technique [0002] Rice is a cereal crop belonging to the genus Oryzae. The representative species is rice. Rice is native to China and India. The ancestors of the Yangtze River Basin in China planted rice seven thousand years ago. According to the type of rice, rice is divided into indica rice and japonica rice, early rice and middle and late rice. , glutinous rice and non-glutinous rice are divided into conventional rice and hybrid rice according to the way of saving seeds, and there are other classifications. According to whether soilless cultivation is divided into paddy field rice and floating rice; according to the life cycle, it is divided into seasonal rice and "lazy rice" ( According to height, it can be divided into ordinary rice and giant rice of about 2 meters; according to saline...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency biogas slurry water-saving system in rice irrigation, which solves certain defects in the existing biogas slurry irrigation system. Most of the existing biogas slurry irrigation systems use flood irrigation Although it can play a good role in fertilization, it will cause waste of biogas slurry and cannot improve its actual utilization efficiency.
