Description
Technical field
The utility model relates to a kind of sample collection device for measuring rice field potassium element whereabouts.
Background technology
Potassium element is one of necessary three large nutrients of paddy growth, is the activator making more than 60 kind of enzyme in object, and has obvious regulating action to crop C, N metabolism; Potassium element is used and is also played an important role to improving soil fertility and raising rice yield and quality.But, China is the country that a Potassic fertilizer resources is relatively deficient, in recent years, due to the raising of crop yield and multiple crop index, the potassium element that crop takes away from farmland is far above input, and farmland deficiency of potassium has become the subject matter of restriction China's agricultural production and increasing peasant income.Recent two decades comes, large quantifier elimination and production practices show, China's anthropogenic soil Potassium status deficiency seriously restricts the development of agricultural production, therefore, paying attention to soil potassium research and the research of potash fertilizer science application technique will be the long-term and difficult task of China soil and fertilizer worker face from now on.
Therefore, the efficiency utilization of different source of manure potassium element in agricultural is carried out for the maintenance of China's agricultural sustainable development and China's agricultural land soil potassium element fertility with improve significant.But the conversion after being manured into soil for different source of manure potassium element at present and whereabouts are also unclear, understand fully this problem, potassium element Rational Application amount and application process could be determined to the effect in plant growth by the different source of manure potash fertilizer of scientific evaluation, also can for improving potassium utilization rate, reduce the loss of potassium element Important Theoretic Foundation is provided.
The circulation of potassium can be divided into " water system ", " plant " and " soil " three metacyclic, mutual contact between them.All with agricultural production with improve the relevant activity of output, all can increase the metacyclic potassium of soil and enter the metacyclic of plant and water system.Potassium does not form organic in soil plant system, enters air hardly.Potassium is stronger than phosphorus with the migration flowing of water, and more weak than nitrogen, circulation approach is also few than nitrogen.In order to maintain enough potassium elements, to enter plant metacyclic, only has by reclaiming the biological clamps (as straw-returning) carried outside from soil and again potassium being introduced this circulation in the mode of fertilising.Potassium enters water system circulation, can not cause the eutrophication of water body, but potassium proceeds to water system circulation time from the soil liquid, and major part will run off.Therefore, have following several whereabouts after potassium element is manured into soil: a part of potassium element is absorbed by crops, a part remains in soil with different shape, and some enters water body environment by runoff and seepage.For potash fertilizer in the past in studying, especially variety classes potash fertilizer be manured into soil after whereabouts comparatively ignore, or to the conversion of fertilizer potassium in crop-soil-environmental system, whereabouts and the inadequate system of loss access, the whereabouts problem causing potassium attainment in Rice Cropping to be divided it be unclear that.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of device collecting percolating water, runoff water, soil, Plant samples, to monitor the whereabouts of potassium element in rice field.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of device measuring potassium element whereabouts in rice field, comprise support, the middle part of described support is provided with laminate and is divided into by described support two-layer up and down, be provided with water barrier inside described upper strata and form percolating filter, be provided with dividing plate in described percolating filter and described percolating filter is isolated into the identical test site of multiple size, at least three test buckets are placed in each test site, be provided with bottom percolating filter and the test bucket mounting hole tested barrel size and mate, described test bucket is placed in test bucket mounting hole, some exposes percolating filter to make test bucket, the bottom of test bucket is provided with weepage holes, the bottom of described test bucket is equipped with nylon stratum reticulare from the bottom up successively, fine sand layer and rock layer, height in described test bucket after laying is concordant with bottom percolating filter, weepage holes is by coupling arrangement and tubes connection, conduit is connected through with the leakage water collecting bucket that bottom, hole is placed from through hole, the upper shed of described test bucket is concordant with the opening of percolating filter, the distance upper soll layer 8-10cm place, upper end of described percolating filter and test bucket arranges freeing port, the freeing port of described test bucket is connected with the runoff water gathering barrel be arranged in hole by conduit.
The internal diameter of described test bucket is 20-60cm.
Adopt said method, the utility model by set up percolating filter by by paddy rice undisturbed soil by level integral moving in percolating filter, ensure not change original external environment condition, and test bucket is set in percolating filter, by laying nylon wire in test bucket, fine sand and stone prevent the loss of soil, and the downward sedimentation of test bucket is arranged in percolating filter, make to lay nylon wire, fine sand is consistent with percolating filter bottom level with the test bottom of the barrel height after stone, in warranty test bucket, soil environment is consistent with the soil environment outside test bucket, rice cultivation in test bucket is comprised in percolating filter, in fertilising process, substitute potash fertilizer with isotope-labeled fertilizer to apply fertilizer to the paddy rice in test bucket, by arranging freeing port at test bucket higher than upper soll layer 8-10cm place, runoff water is collected, weepage holes is set with in test bottom of the barrel percolating water is collected, thus can to different times runoff water, percolating water carries out collecting and detecting, the plant of the paddy rice after maturation and pedotheque are gathered, reach plant absorption in Rice Cropping, seepage, in runoff, the whereabouts of potassium element carries out the object of monitoring.
In sum, the utility model is monitored the whereabouts of potassium element in plant absorption, seepage, runoff, soil in Rice Cropping by isotope labelling method, specifies the transfer of potassium element in rice crop-soil-Environment-Ecosystem, conversion and Distribution dynamics.For the Appropriate application of paddy rice potash fertilizer provides science data, to promoting that the optimization of potash fertilizer in Rice Cropping is used, reduce the loss, improve potash fertilizer utilization ratio and increasing peasant income, Speeding up Construction of New Socialistic Country and Ecological Civilization Construction paces etc. are all significant.
