Description
Technical field
The present invention relates to a kind of composable screen frames that radicula is surveyed for interior growth core method, are used to fill nothing when being measurement radicula
The product design of sampling apparatus needed for root soil, belongs to ecological study field.
Background technique
Plant fine root (Root system) play an important role to Nutrient Cycling and carbon enrichment, and the root system of plant survive
In soil environment, it is difficult to directly be observed its physiological ecological activity, increase research difficulty, Fine Root Biomass and life
Long research is especially not easy to carry out, and lacks the unified reliable method of sampling to the research of radicula, used radicula research method has
Root bores method, interior growth method and mini-rhizotron method, interior growth core method be apply more universal research Fine Root Biomass, productivity and
The effective ways of turnover.
The field operation operation of interior growth core method is first to construct a unrooted earth pillar in the hole dug, after a period of time, adopt
The Fine Root Biomass grown into sample measurement earth pillar.The diameter and depth that measure unrooted earth pillar feature and are ground with depending on the sample of test
Study carefully content.Currently, being used to fill the mostly of unrooted soil in growth core method inside is the gauze or nylon net bag sewed, to guarantee earth pillar
The root system inside grown into is the root system equal to or less than 2mm, and the mesh of gauze or nylon net bag is 10 mesh (2mm), uses gauze
Or nylon net bag manufactures unrooted earth pillar, is put into hole, periphery is filled up with unrooted soil；Or soil mould is put into the hole dug
Gauze or nylon wire are placed in one by son, then are filled up with sieving unrooted soil by original soil layer, and surrounding is also filled out with unrooted soil
Soil mould is taken out after full, is needed by test, after growing a period of time, when sampling, is cut off the root of periphery, is taken out mesh bag, point soil
Layer sampling, filters out radicula.
Growth core method is surveyed in the field operation operation of radicula inside, and when with gauze or nylon net bag filling unrooted soil, operation is not
Just, not easily molded and not easy to control plus native depth, for successively backfill the unrooted soil after sieving according to original soil layer
Operation increases difficulty, expends the time, and efficiency is lower, and with soil mould, working strength is increased, when extending field process
Between；In addition, when taking out earth pillar, the gauze or nylon wire for filling sandy loam can be not easy to be completely cured because being not easy to keep shape, Stratified Sampling
When can increase test error.The sampling point that measurement radicula test needs to arrange is more, so, develop a kind of easy to operate, saving
The field process time, working efficiency is improved, the device for reducing test error is imperative.
Summary of the invention
It is a kind of for interior growth core method survey radicula the invention mainly solves the technical problem of providing a kind of device
Composable screen frame, when with interior growth core method measuring plants radicula, the screen frame of filling unrooted soil, the screen frame can with assembly and disassembly,
It is easy to be formed, guarantees that soil successively backfills, keep the molding of unrooted earth pillar, convenient for layering of being completely cured after taking-up, and it is raw not influence radicula
It is long.
The present invention is implemented as follows:
1. construction:
A kind of composable screen frame for surveying radicula for interior growth core method, it is made of net post, connector and bottom cover, special
Sign is that net post is by rectangular web plate roll-forming, and web plate or so fence has respectively corresponded two rows of protrusions and groove, convenient for button
It closes to fix and forms cylindrical body, and the pulling-on piece on raised prism opposite, convenient for dismantling connector when taking sample, layering of being conveniently completely cured.
2. a kind of application method for the composable screen frame for surveying radicula for interior growth core method, comprising the following steps:
(1) roll net post: the web plate for being rolled into net post is made of 10 mesh (2mm) mesh and two column fence (length 2cm), and two
Short side has two column protrusion and groove respectively, fastens corresponding two column protrusion after web plate volume respectively and net post is made in groove, raised
There is one small pulling-on piece (1cm2) in the middle part of the back side, barrier portion and web plate other faces are staggered the rugosity of 1 twine, and have 2cm coincidence,
It is deformed after can preventing volume, fastening part is that fence will not interfere radicula ingrowing.
(2) connect net post: choose narrow side can loose formula nylon cable tie, be each passed through two connected overstriking sides of connection net posts
Silk, is strained and fixed, between every 2 net posts by 4 can loose formula nylon cable tie fix.
(3) assemble screen frame: after 3 of roll-forming or 3 or more net posts are connected with more nylon cable ties, bottom is used
Bottom cover fastens, and is assembled into screen frame, in field operation operation, is put into hole, unrooted soil is successively loaded, for surveying 30cm or being deeper than 30cm
The radicula of 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 nylon cable tie, in
Net post junction is completely cured layering, and bottom cover is removed；Every layer of pulling-on piece for catching hold of connector respectively, successively dismantles each net post, takes out respectively
The earth pillar of long radicula, sieves and washes out radicula, in case measurement.
Beneficial effects of the present invention:
The present invention provides a kind of composable screen frame that radicula is surveyed for interior growth core method, the composition groups of this device
Part, is rectangle web plate and barrier board before rolling assembling, and regular shape saves packaging space, field operation is facilitated to carry；In field operation
It is not necessarily to auxiliary tool when assembling, is easily assembled to disassemble, roll after being combined into screen frame, can be formed, it is native convenient for successively backfill unrooted,
Having one side at each component fastening is fence, does not influence fine root production, after growing into radicula in screen frame, when sampling, and convenient for layering of being completely cured,
This invention has the features such as being convenient for carrying, easy to form, easy to operate, reduces the field operation operation difficulty of measurement radicula, section
Save the field operation working time.
