Description
Technical field
It is thin with interior growbag method measurement plant the present invention relates to a kind of adjustable screen frame for surveying radicula for interior growbag method
The product design of sampling apparatus when root, is related to ecological study field.
Background technique
Plant fine root refers to that root diameter is equal to or less than the root system of 2mm, and it is root system that radicula absorbs moisture and nutrient from soil
In most important, most active part, radicula production has enough to meet the need and has important work to the distribution of carbon and nutrient, circulation in the ecosystem
With it is still to answer that interior growbag method, which can obtain Fine Root Biomass, carbon nitrogen content and Fine root turnover, compared with root bores method and mini-rhizotron method
With more universal effective ways.Interior growbag method is that basis grows into the biomass of root system and embedded life in dress unrooted soil growbag
The time of long bag, estimate the productivity of root system in the period, the diameter and depth of unrooted earth pillar are depended on studying sample and studied
Purpose, the diameter for measuring earth pillar have 5cm, 6cm, a 7.5cm.....10cm, measurement depth of soil be mostly 30cm, 40cm, 60cm or
1m, soil thickness are mostly 10cm or 20cm.
Being used to fill the mostly of unrooted soil in interior growbag method at present is the gauze or nylon net bag sewed, to guarantee to grow into life
Root system in long bag is the radicula that diameter is equal to or less than 2mm, and the mesh of mesh bag is 2mm.In present field operation operation, nothing is constructed
When root earth pillar, over-borrowing, which helps gauze or nylon wire, forms earth pillar, and periphery is filled up with unrooted soil again, or puts in the hole dug
Enter soil mould, place into gauze or nylon wire, is then filled up with sieving unrooted soil by original soil layer, surrounding also uses nothing
Root soil fills up, and takes out soil mould, needs by test, after growing a period of time, cuts off the root of periphery, takes out mesh bag, divide soil layer
Sampling, sieves and washes out radicula.
In above-mentioned field operation operation, when filling unrooted soil, gauze or nylon net bag are not easy to be formed, inconvenient, efficiency compared with
It is low, it is formed with soil mould time-consuming, increases field process intensity, be not easy successively to backfill, be not easy to keep original soil
Level；And in sampling, the gauze or nylon wire for filling sandy loam can be not easy to be completely cured because being not easy to keep shape, and when Stratified Sampling can
It can increase test error, and respectively have feature with measuring the sample that radicula is tested, research purpose is not quite similar, and the sampling point for needing to arrange
More, urgent need develops one kind and can satisfy different tests needs, easy to operate, reduces working strength, improves adopting for working efficiency
Sampling device.
Summary of the invention
The object of the present invention is to provide a kind of adjustable screen frames that radicula is surveyed with interior growbag method, this is to sample a kind of device,
For loading unrooted soil.The internal diameter of the screen frame is adjustable, and to meet different tests requirement, adjustable screen frame is convenient for assembly and disassembly,
It is easy to be formed, guarantees that soil successively backfills, does not interfere fine root production, and convenient for layering of being completely cured when sampling.

Do not there is I-shaped edge strip and inserting column to plug together connection, net bottom is the round mesh sheet of the different-diameter of periphery overstriking, connection net post and
The control joint of net bottom be by middle part indent can loose formula band roll.
2. a kind of application method for the adjustable screen frame for surveying radicula for interior growbag method, comprising the following steps:
(1) roll net post: when measuring earth pillar diameter is 5cm, the web plate for rolling net post is exactly a wire side (5 π of length
Cm, width 10cm), wire side rolls rear two sides I-shaped edge strip and inserting column plugs together into the net post that internal diameter is 5cm；In measurement earth pillar
When diameter 6-10cm, the web plate of adjustable net post is rolled by mesh sheet (length 10cm, width n the π cm of wire side and different in width；N=
0.5,1,2) it constitutes, wire side and mesh sheet are plugged together by two sides I-shaped edge strip and inserting column and be spliced into adjustable web plate, net post internal diameter
Adjustable is 5.5,6,6.5,7.5......10cm.
(2) roll connector: by middle part indent can loose formula band be rolled into control joint, the depth of indent is 1 overstriking net
The rugosity of silk, width are the rugosity of 2 overstriking twines.
(3) it assembles screen frame: 3 net posts of roll-forming and net bottom being connected and composed into screen frame with 3 control joints, or will
Three or more the net posts and connector (can loose formula band) of roll-forming be connect with a net bottom synthesizes screen frame, successively fills unrooted
Soil is respectively used to survey 30cm or is deeper than the radicula of 30cm soil depth.
(4) disassemble screen frame: when sampling, cutting off the root system of screen frame periphery, take out screen frame, unlock can pine formula band, successively tear open
Connector is opened, net bottom is removed, is completely cured layering in net post junction, is taken out the earth pillar of long radicula respectively, sieve and wash out radicula.
Beneficial effects of the present invention:
The present invention provides a kind of adjustable screen frame for surveying radicula for interior growbag method, this device can be by adjusting screen frame
Internal diameter meet the different needs that generate because test actual conditions, constitute component before splicing rolls, regular shape, saving
Packaging space carries convenient for field operation, in field operation grafting, rolls and be not necessarily to auxiliary tool when assembling, be easily assembled to disassemble, be convenient for
Adjust screen frame internal diameter；Grafting after rolling and being combined into screen frame, can be formed, to guarantee successively to backfill unrooted soil by native soil level,
Each component junction does not influence fine root production, when sampling, convenient for layering of being completely cured.For the accessory of adjustable screen frame, a collection of product can
Meeting a variety of test demands, sexual valence is relatively high, and it is easy to operate, the field process time is saved, field process intensity is reduced.
