Technical field
The invention belongs to soil monitoring technical field, particularly relate to soil moisture under the different topsoil structure of a kind of simulation and support
Divide the outdoor earth pillar device of transportion and transformation and plant growth.
Background technology
Good topsoil structure plays an important role in raising grain yield, guarantee national food security.20th century 70
In the later stage in age, with the progressively popularization of the introduction of external rotary tillage machine and rotary tillage, substantially increase farming efficiency especially, with ploughing
Comparing with rake farming industry, it is good that rotary tillage process has hack performance, strong adaptability, the high advantage of operating efficiency.But it is long-term to revolve generation
Ploughing, also progressively exposing some problems, the existing rotary tillage degree of depth is typically at about 15cm, than the shallow 8-of mechanical ploughing depth in past
10cm, causes topsoil to shoal；Rotary tillage year after year simultaneously, forms between arable layer and subsoil owing to the squeezing action of colter causes
One layer of plough sole hard, that close, and the clay that long-term broad irrigation causes gathers effect, exacerbate this plough especially
Basement effect.
For anthropogenic soil, there is the plough sole of suitable thickness to keeping nutrient, preserve what moisture was still highly profitable；
But plough sole is blocked up, solid, not only hinder crop root intert, hinder simultaneously water between arable layer and subsoil, fertilizer,
The connectedness of air and heat.But the existence of plough sole actually can to soil moisture nutrient transfer conversion and plant growth generation what
Plant impact？And which type of topsoil structure is only most beneficial for raising crop water nutrientuse efficiency, thus increase yield
Reduce greenhouse gas emission and nutrient deep layer leaching？Being limited to the shortage of current research means or device, these problems also do not have at present
