Vynález sa týká lyzimetra na meranie eva-potranspirácie experimentálně pěstovanýchrastlín.BACKGROUND OF THE INVENTION The present invention relates to a lysimeter for measuring eva-transplantation of experimentally grown plants.
Doteraz známe lyzimetre sú zalóžené naprincipe kompenzácie úbytku podnej vodyevapotranspiráciou na úroveň pofnej kapa-city, to znamená, že v nich možno merať ibaevapotranspiráciu potenciálnu. Lyzimetre sgravimetrickou kontrolou obsahu podnej vo-dy pracujú s chybou, spósobenou narastanímhmotnosti pěstovaných rastlín. V tzv. měr-ných lyzimetroch, kde sa meria obsah pód-nej vody vhodnými metodami, dochádza khromadeniu vody priesakom bez možnostijej odstraňovania.The lysimeters known so far are based on the principle of compensating for the loss of groundwater by apoptosis to the level of capillary capacity, that is to say, only the potential transplantation can be measured. The lysimeters with sgravimetric control of the content of the underwater work with an error caused by the increase in the weight of the cultivated plants. In so-called measured lysimeters, where the content of the ground water is measured by suitable methods, water accumulates through leakage without the possibility of removal.
Uvedené nedostatky odstraňuje lyzimeterpodlá vynálezu, ktorého podstata spočívá vtom, že v střede nádoby lyzimetra je ulože-ná vynímatelná pažnica, ktorá je na svojomdolnom konci opatřená perforovaným ná-stavcom pre doplňovanie, alebo odčerpává-me vody.The above mentioned drawbacks are solved by the lyzimeter according to the invention, characterized in that a removable casing is provided in the center of the lysimeter, which is provided with a perforated adapter for refilling or draining water at its bottom end.
Lyzimetre tohoto typu sú nevyhnutným za-riadením na výskům vodného režimu rastlína pódy. Umožňujú spolahlivú reguláciu ob-sahu pódnej vody v prirodzených podmien- 2 kach odoberaním, alebó přidáváním cez paž-niču, ktorá slúži súčašne na meranie jej ob-sahu neutronovým meračom v celej híbkelyzimetra. To umožňuje získat údaje o změ-nách spotřeby vody polnohospodárskych plo-din v stanovených časových intervaloch. Za-riadenie je v podstatě jednoduché, nenároč-né na údržbu a má dlhú životnost.Lysimeters of this type are an indispensable device for the water regime of the Peak Plant. They allow reliable regulation of the water content of the natural conditions by withdrawal or addition through the casing, which serves to measure its content by a neutron meter throughout the meter. This makes it possible to obtain data on changes in water consumption of agricultural land at specified time intervals. The device is basically simple, low-maintenance and has a long service life.
Zostavenie lyzimetra podlá vynálezu je zo-brazené na pripojenom výkrese, kde znázor-ňuje obr. 1 podorys lyzimetrickej nádoby,obr. 2 lyzimeter v řeze A—A‘ z obr. 1 a obr.3 detail B z obr. 2. V lyzimetrickej nádobě 1 zo sklolaminátuje navrstvená podá, do ktorej je centrálnězasunutá pažnica 2, vyčnievajúca 30 cm nadjej povrch. Do spodného otvoru pažnice 2 jezasunutý perforovaný nástavec 3, obr. 3. Vovnútornej časti nástavca 3 je vložená filtrač-ná hmota 5, oddělená od pažnice 2 perforo-vanou přepážkou 4. Pri nadbytku, alebo ne-dostatku vody v lyzimetri sa jej obsah regu-luje cez pažnicu 2 odčerpáváním, alebo do-plňováním. Okrem toho sa pažnica 2 využívána zasúvanie snímača pri meraní pódnej vo-dy do potřebných hlbok. 226106The lysimeter assembly of the present invention is shown in the accompanying drawing, wherein FIG. 2, a lysimeter in section A-A of FIG. 1 and FIG. 3 a detail B of FIG. 2. A perforated extension 3, FIG. 3 is inserted into the lower opening of the casing 2. A filter mass 5 separated from the casing 2 by a perforated partition 4 is inserted into the inner part of the extension 3. In the case of excess or insufficient water in the lysimeter, its contents are adjusted through the casing 2 by pumping or filling. In addition, the casing 2 is used to insert the sensor to measure the base water to the required depths. 226106
