Description
Technical field
The present invention relates to root case experimental provision technical field, is specifically related to a kind of root for plant rhizosphere Environmental Studies
Case experimental provision.
Background technology
Rhizosphere is that root system of plant and soil carry out nutrient and the important area of energy exchange, is that edaphon is most active
Place, influenceed by crop root growth, while influence the specific region of the absorption and operating of crop nutrition content again.Root system secretion
The materials such as organic acid, carbohydrate, enzyme are dissolved in strong organic, heavy metal classes polluter the tax influenceed in soil after the soil water
Deposit, migrate, conversion process and rule.Therefore, rhizosphere micro-region is always domestic and international agrology, Plant Nutrition, agronomy, environmentology
One of focus Deng multidisciplinary research.
For the sampling method of rhizosphere soil, past existing more research.Traditional method is to shake based on separation, but nothing
Method avoids sampling amount heterogeneity, quantifies not influence of the science to experiment accuracy.Some scholars use freezing method, but cut
Piece thickness is difficult to control, and can produce crimp to soil during section, while quick-frozen process can change the nutrient situation of soil
And microbial activity.It is now to have been reported that using more interlayer root casees more, soil is divided into by rhizosphere soil and Non-rhizosphere soil by nylon wire
Earth, closely it is affixed by interlayer, carries out grade sampling, but differentiation of the research so far for rhizosphere and non-rhizosphere soils region
It there is no and accurately define, so the root case of fixed dimension is difficult to accomplish the matching correct with rhizosphere and non-rhizosphere soils, root case is done
It is too big to waste, root case do it is too small i.e. may be surely incomplete to rhizosphere regional boundary.For the sampling method of rhizosphere soil water,
Also there is more research in past.Traditional method is to take out based on soil centrifugation, but this can destroy soil conditions, and vegetation period
It is interior to sample.Some scholars or mechanism take soil water sample using soil water sampler, but to rhizosphere nutrients earth,
The soil water is combined the research being sampled and is rarely reported.
The content of the invention
, can be accurately square using the present apparatus the invention provides a kind of root case experimental provision for plant rhizosphere Environmental Studies
