The materials such as organic acid, carbohydrate, enzyme are dissolved in strong organic, heavy metal classes polluter the tax affected 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 based on shaking and separate, but nothing
Method avoids sampling amount heterogeneity, quantifies not impact of the science to experiment accuracy.Also there is scholar to adopt freezing method, but cut
Piece thickness is wayward, and can produce crimp to soil when cutting into slices, while quick-frozen process can change the nutrient situation of soil
And microbial activity.It is now to have been reported that using many interlayer root casees more, soil is divided into by rhizosphere soil and Non-rhizosphere soil by nylon wire
Earth, is closely affixed by interlayer, carries out grade sampling, but research so far for the differentiation in rhizosphere and non-rhizosphere soils region
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 that root case does
It is too big to waste, root case do it is too little 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.To take out based on soil centrifugation, but this can destroy soil conditions, and vegetation period to traditional method
It is interior to sample.Also have scholar or mechanism to take soil water sample using soil water sampler, but to rhizosphere nutrients earth,
The soil water research being sampled that combines is rarely reported.
