Description
本發明係關於一種介質孔隙度測量裝置，特別是關於一種用以控制液體由下往上填充土壤介質，使測量精準度提高之孔隙度測量裝置。BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a medium porosity measuring device, and more particularly to a porosity measuring device for controlling the filling of a liquid medium from bottom to top to improve measurement accuracy.
介質為植物生長的主要環境條件之一，包含土壤介質及非土壤介質，負責提供固著、空氣、水分和養分。其中空氣、水分和養分均分布於土壤介質顆粒間的孔隙中，而盆栽容器的體積遠較地上土壤中的小，如何在這有限的空間中提供最多的水分和空氣，供植株良好的生長條件，同時在規格化高品質量產的設施中更要求精確一致的控管水分和肥料，以達到資源和成本的節約，及符合環保的規章限制，這些都有賴於對盆栽土壤介質的了解和長期監控管理。The medium is one of the main environmental conditions for plant growth, including soil media and non-soil media, and is responsible for providing fixation, air, moisture and nutrients. The air, water and nutrients are distributed in the pores between the soil media particles, and the volume of the potted container is much smaller than that in the above ground soil. How to provide the most moisture and air in this limited space for the good growth conditions of the plants At the same time, in the standardized high-quality products, more precise control of water and fertilizer is required to achieve resource and cost savings, and compliance with environmental regulations. These depend on understanding and long-term understanding of potted soil media. Monitoring management.
在測量介質孔隙度時，較重要係量測總孔隙度(Total Porosity,TP)，總孔隙度係容器水含量(Container Capacity,CC)及充氣孔隙度(Air Space,AS)之加總，即TP=CC+AS。When measuring the porosity of a medium, the total porosity (Total Porosity, TP), the total porosity, the container water content (CC) and the aerated porosity (AS) are added. TP=CC+AS.
現行測量植株盆栽內土壤介質的孔隙度，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內測量，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。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.
習用之介質孔隙度測量裝置，主要係為一容器，該容器設有一容置空間，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內，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，重新填裝於該容器內測量，則由於土壤介質顆粒的重組以及密度的改變，使土壤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。The conventional medium porosity measuring device is mainly a container, and the container is provided with 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 accommodating 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 have made the distribution of pores in the soil medium 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 top to bottom, the impact force of the liquid infusion causes the original agglomerate. The structure is easily damaged, and this filling method is easy to generate bubbles in the medium, so the obtained value does 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 measurement. Moreover, since the conventional porosity measuring device is required to provide a liquid storage tank, it causes an error in liquid filling, and in particular, causes a serious error in the inflation porosity. In other words, the conventional medium porosity measuring device cannot directly measure all the water filled in the pores of the medium, that is, the inflated porosity cannot be measured, and of course, the total porosity cannot be accurately measured. The measurement is not accurate.

本實施例之介質孔隙度測量裝置在實施上，將該容器65裝滿土壤介質，與盆栽5作相同之用途，並能藉由該導液管2導入或排出液體，用以量測土壤介質的最小充氣孔隙度，該實施步驟與第一實施例相同，在此不再贅述。In the implementation, the medium porosity measuring device is filled with the soil medium, and is used for the same purpose as the potting 5, and the liquid can be introduced or discharged by the liquid guiding tube 2 to measure the soil medium. The minimum venting porosity is the same as that of the first embodiment, and details are not described herein again.
本發明之介質孔隙度測量裝置，除藉由上述實施例外，本發明還可以將數個固定盤設置於該數個導液管上，且該數個導液管可連通於供水箱與液位控制單元，因此，本發明具有可同時量測數個樣品之特性，則可以縮短量測土壤介質孔隙度所耗費時間。In the medium porosity measuring device of the present invention, in addition to the above embodiments, the present invention can also provide a plurality of fixed disks on the plurality of liquid guiding tubes, and the plurality of liquid guiding tubes can be connected to the water supply tank and the liquid level The control unit, therefore, the invention has the characteristics of simultaneously measuring a plurality of samples, thereby shortening the time taken to measure the porosity of the soil medium.
本發明之介質孔隙度測量裝置，藉由液位控制單元控制液面之高度，使液體由下往上緩慢灌注於土壤介質，又藉由導液管之連接部設計，可以緩衝灌注於土壤介質之衝擊力，使得土壤介質原始團粒構造不受到破壞，因此所得到的數值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。The medium porosity measuring device of the invention controls the liquid level by the liquid level control unit, so that the liquid is slowly poured into the soil medium from bottom to top, and the connection portion of the liquid guiding tube is designed to buffer the infusion into the soil medium. The impact force makes the original agglomerate structure of the soil medium undisturbed, so the obtained value can represent the physical properties of the soil medium during the growth of the true plant and the root zone of the plant.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
