Device for accelerated rice straw desalinating and returning by high-voltage static electricity for saline-alkali land restoration

Abstract

A device for accelerated rice straw desalinating and returning by high-voltage static electricity for saline-alkali land restoration belongs to the technical field of tillage and cultivation. The device is composed of a high-voltage electrostatic generator (1), a stirring push motor (2), a feeding chamber (3), an immersion and desalination chamber (4), a degrading bacteria liquid chamber (5), a salt collection chamber (6), a salt collection chamber door (11), support feet (12), a bracket (16), a water adding chamber door (21) and a degrading bacteria liquid chamber door (23). The device is characterized in that the high-voltage electrostatic generator (1) is a device for generating high-voltage static electricity, a high-voltage electrostatic plate (15) of the device has a copper core inside and a rubber insulating surface layer on the surface thereof, and there is an included angle of 5-10 degrees between the central axis in the width direction and the central axis in the vertical direction of the immersion and desalination chamber (4); and there is a spiral bulge with a height of 3-5cm and a pitch of 1-2cm on the conical outer surface of a spiral push rotor (20). The device has the advantages of simple manufacture, strong operability, low cost and obvious effect.

Description

technical field [0001] The invention relates to a high-voltage electrostatic accelerated desalination and returning device for rice straw used for saline-alkali land restoration, which belongs to the technical field of farming and cultivation. Background technique [0002] There are 950 million hectares of saline-alkali land in the world, 320 million hectares of saline-alkali land in Asia, and 100 million hectares and 1.5 billion mu of saline-alkali land in China, of which 280 million mu of saline-alkali land can be developed and utilized. At present, China has more than 200 million mu of saline-alkali land that can be used to grow rice. Based on the future yield of 200-300 kg per mu, it can increase grain production by tens of billions of kg and feed about 200 million more people. After the gradual promotion of large-scale planting of rice in the future, it will involve the problem of reducing the salinity of saline-alkali land and returning rice straw to the field. Straw ...

AI Technical Summary

Problems solved by technology

Straw returning to the field has a significant effect on increasing fertilizer and production, and generally can increase production by 5% to 10%. However, if the method is not appropriate, it will also lead to an increase in soil pathogens, aggravation of crop diseases, and lack of seedlings (sick seedlings) and other undesirable phenomena
