Description of the invention: [Technical field to which the invention pertains] Measuring device 'in particular with respect to a medium for measuring accuracy The present invention relates to a porosity measurement of a medium for controlling the liquid to be filled from bottom to top to improve the porosity measurement Device. [Prior Art] The medium is one of the main environmental conditions for plant growth, including and non-soil media, and S is responsible for raising, licking, moisture and nutrients. The air, water and nutrients are distributed in the soil age f._ pores, and the volume of the potted container is much smaller than that in the ground soil. How to provide the most water and money in this limited space for the good growth conditions of the plants At the same time, in the high-quality and high-quality facilities, more precise control of water and fertilizer is required to achieve resource and cost savings, and compliance with environmental regulations. These depend on the understanding and long-term understanding of the money band (4). Monitoring management.
在測量介質孔隙度時，較重要係量測總孔隙度(T〇tal Porosity，TP)，總孔隙度係容器水含量(c〇mainer〜狀办， CC)及充乳孔隙度(Air Space, AS)之加總，即TP = CC + AS。 現行測量植株盆栽内土壤介質的孔隙度，採取土壤樣 品時多數需要破壞植物根系周圍介質的原始團粒構造，重 新填裝於特定容器内測量，此時由於土壤介質顆粒的重 組，以及密度的改變，導致土壤介質孔隙的分布已經和採 樣之前不同，因此所得到的數值不能代表真正植株生長期 間，植物根圈土壤介質的物理特性。 201024708 翫用之介質孔隙度測量裝置，主要係為一容器，該容 器v又有一容置空間，且該容器分別設有一開口部及數個通 孔，該開口部及各該通孔分別貫通該容置空間。使用時係 採取土壤介質裝填於該容器之容置空間内，由於在採取土 壤介質時容易破壞植物根系周圍之土壤介質的原始團粒構 造，重新填裝於該容器内測量，則由於土壤介質顆粒的重 組以及密度的改變，使土壌介質孔隙的分布已經和採樣之 前不同。此外，習用之孔隙度測量裝置另需設置一儲液槽， 將該容器置於儲液槽後再灌注液體，由於液體之灌注是由 上往下填充，則液體灌注時之衝擊力使得原始團粒構造易 受到破壞，且此填充方式易於介質中產生氣泡，因此所得 到的數值不能代表真正植株生長期間及植物根圈之土壤介 質的物理特性’造成量測不準確。再者，由於習用孔隙度 測量裝置須設置儲液槽，因此會造成液體填充之誤差，特 別是，造成充氣孔隙度之嚴重誤差。換句話說，習用之介 質孔隙度測量裝置無法直接量測充滿於介質孔隙中的所有 水量，即為無法量測充氣孔隙度，當然也無法準確量測總 孔隙度。造成量測不準確。 【發明内容】 本發明之主要目的，係提供一種介質孔隙度測量裝 置，能量測充氣孔隙度。 本發明之次一目的，係提供一種介質孔隙度測量裝 置，能準確量測總孔隙度。 本發明之另一目的，係提供一種介質孔隙度測量裝 201024708 置’利用液體由下往上填充土壤介質，使該孔隙度測量裝 置所測得的數值較為準確。 本發明之再一目的，係提供一種介質孔隙度測量裝 ： 置，能在不破壞原始團粒構造下進行量測。 . 本發明之另一目的，係提供一種介質孔隙度測量裝 置，利用液體由下往上填充，使介質中不易產生氣泡，提 高準確量測準確。 本發明之又一目的，係提供一種介質孔隙度測量裝 ❹ 置，能同時量測多組樣品。 本發明之另一目的，係提供一種介質孔隙度測量裝 置，能直接使用樣品容器，直接於樣品容器内注液量測。 本發明之介質孔隙度測量裝置，包含：一固定盤具有 一第一面、一第二面及數個貫通該第一面與第二面之通 孔；一導液管設有一主流管、一第一管及一第二管，該主 流管以連接部與該固定盤之第二面所設數個通孔相連通； ©該第一管第一端與主流管連通，該第一管第二端可導入液 體；該第二管第一端與第一管連通；及一液位控制單元第 „ 一端係連接該第二管第一端，第二端係形成開放端。藉由 ； 該液位控制單元控制液面高低，使液體由下往上緩慢填充 土壤介質。 【實施方式】 為讓本發明之上述及其他目的、特徵及優點能更明顯 易懂’下文特舉本發明之較佳實施例’並配合所附圖式， 作詳細說明如下： 201024708 、則曰示，本發明第—實施例之介質孔隙度 := 定盤1、一導液管2、-供水箱3及-液When measuring the porosity of the medium, the more important measures are the total porosity (T〇tal Porosity, TP), the total porosity is the container water content (c〇mainer~, CC) and the water storage porosity (Air Space, The sum of AS), ie TP = CC + AS. At present, the porosity of the soil medium in the potted plants is measured. When the soil samples are taken, most of the original aggregate structure of the medium surrounding the roots of the plants needs to be destroyed and refilled in a specific container. At this time, due to the reorganization of the soil medium particles and the change of density, The distribution of pores in the soil medium has been different from that before sampling, so the values obtained do not represent the physical properties of the soil medium in the root zone of the plant during true plant growth. 201024708 The medium porosity measuring device is mainly used as a container, and the container v has an accommodating space, and the container is respectively provided with an opening portion and a plurality of through holes, and the opening portion and each of the through holes respectively penetrate the Accommodate space. When used, the soil medium is filled in the accommodating space of the container. Since the original granule structure of the soil medium around the root of the plant is easily damaged when the soil medium is taken, and refilled in the container, the particles of the soil medium are measured. Reorganization and changes in density make the distribution of pores in the soil media different from before sampling. In addition, the conventional porosity measuring device additionally needs to set a liquid storage tank, and after the container is placed in the liquid storage tank, the liquid is poured, and since the liquid is filled from the top to the bottom, the impact force of the liquid infusion causes the original agglomerate. The structure is susceptible to damage, and this method of filling tends to create bubbles in the medium, so the resulting values do not represent the physical properties of the soil medium during the growth of the true plant and the root zone of the plant', resulting in inaccurate measurements. Furthermore, since the conventional porosity measuring device is required to provide a liquid storage tank, it causes an error in liquid filling, in particular, a serious error in the inflation porosity. In other words, the conventional media porosity measurement device cannot directly measure all the water filled in the pores of the medium, that is, the inflation porosity cannot be measured, and the total porosity cannot be accurately measured. The measurement is not accurate. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a medium porosity measuring device for measuring the porosity of an inflation. A second object of the present invention is to provide a medium porosity measuring device capable of accurately measuring total porosity. Another object of the present invention is to provide a medium porosity measuring device that uses the liquid to fill the soil medium from bottom to top, so that the value measured by the porosity measuring device is relatively accurate. Still another object of the present invention is to provide a medium porosity measuring apparatus capable of performing measurement without destroying the original aggregate structure. Another object of the present invention is to provide a medium porosity measuring device which uses a liquid to be filled from bottom to top, so that bubbles are less likely to be generated in the medium, and accurate measurement accuracy is improved. It is still another object of the present invention to provide a medium porosity measuring device capable of simultaneously measuring a plurality of sets of samples. Another object of the present invention is to provide a medium porosity measuring device which can directly use a sample container and directly inject a liquid in a sample container. The medium porosity measuring device of the present invention comprises: a fixed plate having a first surface, a second surface and a plurality of through holes penetrating the first surface and the second surface; a liquid guiding tube is provided with a main flow tube, a first tube and a second tube, the main tube is connected to the plurality of through holes provided on the second surface of the fixing plate by a connecting portion; © the first end of the first tube is connected with the main tube, the first tube is The second end can be introduced with a liquid; the first end of the second tube is in communication with the first tube; and the first end of the liquid level control unit is connected to the first end of the second tube, and the second end is formed to form an open end.
