Description
Technical field
The present invention relates to the research equipment that in soil, root system of plant decomposes, specifically a kind of sample embedded device of monitoring different depth root system of plant decomposition in soil.
Background technology
It is the basic process that ecosystem soil organism Residue decay transforms that root system of plant decomposes, and is the key link of system Nutrient Cycling, has vital role to regulating the utilizability of soil nutrient and maintaining soil productivity.The decomposition of root system of plant in monitoring soil, root system litter decomposition rate and root system decompose of nutrient rate of release can be understood, and understand root system Decomposition of leaf litter further to the utilizability of soil nutrient and Nutrient distribution impact, significant to researching plant root-soil nutrient circulation.
At present, root system is put into the nylon net bag in a certain aperture by the many employings of people, is imbedded by multiple nylon net bag (general 0 ~ 20cm) in a certain soil layer, by sampling at set intervals, in monitoring soil, Root decomposition is dynamic, reaches the object of monitoring Root decomposition speed.But different root system of plant grows degree of depth difference downwards, general Herb Root reaches 1 ~ 2 meter deeply, and the shrub plant root system degree of depth can reach 5 ~ 8 meters; What is more, and arid area Bushes Roots can reach 10 ~ 20 meters deeply.Because below root system vertical distribution scope is very wide, and different depth soil physics, chemistry and biology characteristic are different; Therefore, in different levels soil, root system of plant decomposition rate can there are differences, and only measures a certain degree of depth Root decomposition speed in soil and is difficult to embody different levels soil root decomposition rate difference, truly cannot reflect the overall decomposing level of root system of plant.And if root system bag is imbedded in the hole of different depth by employing, then need to dig in multiple hole or a hole and establish multiple layer, bury root system bag respectively underground, this kind of method wastes time and energy, and is difficult to the accuracy ensureing sampling, the possibility increase that sample is lost.
Summary of the invention
In order to solve the problems referred to above that existing monitoring plant Root decomposition exists, the object of the present invention is to provide a kind of sample embedded device of monitoring different depth root system of plant decomposition in soil.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes straight-bar and mesh bag, wherein straight-bar is provided with the mesh bag of multiple in-built root system of plant from top to bottom, during each mesh bag on described straight-bar is all placed into the soil.
Wherein: described straight-bar is marked with scale; Scale on described straight-bar, for equidistantly to indicate high range on straight-bar, indicates a down scale between two adjacent high ranges; Described down scale is positioned at the centre of two adjacent high ranges, the straight-bar at each down scale place is all connected with a mesh bag; The sack of described mesh bag is fixed on straight-bar by staple, is being provided with a seal location near sack place; On described straight-bar top scale below part place into the soil.
Advantage of the present invention and good effect are:
1. the present invention not only can bury root system sample underground in different depth soil, and sample burial place is accurate, and samples easy, can effectively avoid sample to lose.
2. the present invention buries in process the mode adopting layered backfill underground at sample, reduces soil layer variation, goes back native soil initial position as far as possible, close with natural conditions.
3. structure of the present invention is simple, and low cost of manufacture, operates simple and easy, is suitable for various soil environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlarged drawing at I place in Fig. 1;
Fig. 3 is the schematic diagram that the present invention is applied to field and buries underground;
Wherein: 1 is straight-bar, 2 is scale, and 3 is mesh bag, and 4 is seal location, and 5 is staple, and 6 is square hole.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2, the present invention includes straight-bar 1 and mesh bag 3, wherein straight-bar 1 is diameter is 2.5 ~ 4cm, height is the solid rod of 1.2 ~ 1.4m, straight-bar 1 is provided with the mesh bag 3 of multiple in-built root system of plant from top to bottom, this mesh bag 3 is that to make specification with the nylon net cloth that aperture is 0.5 ~ 3mm be the sack that mouth is stayed in one end of 10 ~ 15cm × 15 ~ 20cm.Described straight-bar 1 is marked with scale 2, this scale 2 is from distance straight-bar 1 top setpoint distance, indicate high range every equidistance downwards, the centre position between two adjacent high ranges indicates a down scale, the straight-bar 1 at each down scale place is all connected with a mesh bag 3; The sack of mesh bag 3 is fixed on straight-bar 1 by staple 5, is being provided with a seal location 4 near sack place, and this seal location 4 is being sealed apart from sack setpoint distance place by mesh bag 3 with line.The present embodiment is using distance 15 ~ 20cm place, straight-bar 1 top as starting point, and mark a high range 2 every 20cm (determining distance according to research needs), the centre position between every two high ranges arranges a down scale again; Apart from sack 3 ~ 5cm place, sack is sealed with line, forms seal location 4, the sealing line Outboard Sections of the seal location 4 of mesh bag 3 is fixed on the down scale of straight-bar 1, with 3 ~ 5 staples 5 fixing (as shown in Figure 2) on each mesh bag.During on straight-bar 1, the part of the scale less than 2 of top is placed into the soil, when burying straight-bar 1 underground, the soil dug out is put in diverse location successively by different depth, the part of the scale more than 2 of the top of straight-bar 1 is exposed earth's surface, during following part is placed into the soil, the soil of taking-up is backfilling in hole successively by different depth, avoids soil layer chaotic.
As shown in Figure 3, when burying underground in the wild, according to sampling number of times, determine the number burying straight-bar 1 underground, sample 12 times in the present embodiment, bury straight-bar 12 underground, every root straight-bar 12 is all vertically buried underground.Test plot is dug 1 meter of dark square hole 6 in the wild, from top layer to bottom, the dark soil of every 20cm is one deck, and the soil dug out is put in diverse location successively by different depth; By to pick up from soil 0 ~ 20,20 ~ 40,40 ~ 60,60 ~ 80 and 80 ~ 100cm root system of plant dry, weigh after put into each mesh bag 3 on straight-bar 1 respectively, record the corresponding root system degree of depth of each mesh bag 3; In hole, lay a straight-bar 1 every setpoint distance, make the part of the scale more than 2 of straight-bar 1 top expose earth's surface, the soil of taking-up is backfilling in hole successively by different depth, avoid soil layer chaotic.Monthly sample once, each taking-up straight-bar 1, takes off the mesh bag 3 of different levels, measures index of correlation in testing laboratory.
