Field plot isolation device

Abstract

The invention provides a field plot isolation device, comprising a plurality of isolation plates, and an isolation plate linear connector and an isolation plate corner connector which are used for connecting the plurality of isolation plates, wherein the isolation plates are rectangular plates made from rigid polyvinyl chloride plates; the isolation plate linear connector consists of a bottom plate and long side buckle strips arranged along a center line of the bottom plate, and the isolation plates are connected by being inserted into the long side buckle strips; the isolation plate corner connector consists of a bottom plate, and long side buckle strips and short side buckle strips which are arranged in an intersecting way along two center lines of the bottom plate; every two adjacent isolation plates are connected by being inserted into the long side buckle strip and the short side buckle strip, and the direction of the isolation device is changed. The field plot isolation device has completely consistent isolation height and isolation effect within a whole rice growing season, and is better in isolation effect.

Description

Technical field [0001] The invention belongs to the field of agricultural production and relates to a field cell isolation device. Background technique [0002] Different fertilizer application tests and water management tests in rice fields require separate fertilization or separate water management between different treatments. There should be no mutual penetration of water or fertilizer between treatments and treatments, otherwise it will affect the accuracy of the test and the reliability of the results. Usually, different communities in the field use soil as ridges, and the ridges are covered with a film to isolate each other. However, it is troublesome to make the mud ridge. If it encounters continuous rain, the mud ridge cannot be completed and the test will be delayed. [0003] The mud ridge requires multiple manual processes, that is, the ridge is made into the ridge before the soil is slightly dried and shaped before the subsequent heightening and widening, and only afte...

Problems solved by technology

However, it is troublesome to make a field ridge with soil. If it encounters continuous rainy days, the soil ridge cannot be completed, and the test will be delayed.

[0003] Soil ridges require multiple manual processes, that is, the height and width of the ridge can only be increased after the ridge soil is slightly dry and shaped in the previous time, and the plastic film can only be covered after the ridge is completely completed, so the soil ridge consumes a lot of labor. Cost; soil ridges are often bent and not straight during manual operation, resulting in inconsistencies in the area of ​​plots between different treatments, which affects the accuracy of the test; soil ridges are in the late growth period of rice, because of rainwater washing and water reduction in the ridges, the height of the soil ridges will decrease. Slowly lower, the water level in the plot is higher when it encounters rainfall, which may cause the fertilizer and water in different plots to infiltrate each other, making the experimental error larger
