Ůčelom vynálezu je zjisíovanie pevnosti stébla vo všetkých smeroch súčasného šlachtenia obilovin najma kukuřice.The purpose of the invention is to determine the strength of the stalk in all directions of simultaneous breeding of cereals, in particular corn.

Uvedeného účelu sa dosiahne prístrojom podlá vynálezu podstatou ktorého je tlačná ihla, ktorá prostredníctvom posuvnej tlačnej tyčky tlačí na vychylovacie ramienko registrátora.This is achieved by the apparatus according to the invention which is based on a thrust needle which, by means of a sliding thrust rod, presses on the deflecting arm of the register.

Registrátor ukazuje na ukazovateli hodnotu tlačnej síly v SI eústave až do zlomenia zkúšaného stébla.The registrar shows the value of the pressing force in the SI system until the tested stem is broken.

Vynález rieši problém hodnotenia biologického materiálu na pevnost’ stébla hybridných materiálov v novošTachtení obilnin proti poliehaniu.The invention solves the problem of evaluating biological material for the stalk strength of hybrid materials in the newly laid lodging of cereals.

Hodnoťenie pevnosti stébla a samotný výběr vhodného materiálu v súčasnosti charakterizujú vizuálně metody, ktoré subjektivné hodnotia tento znak. Pevnost’ stébla sa nesprávné vyjadřuje percentom zlomených rastlín pod šúlkora resp, klasom, lnou metodou, ktorá sa v súčasnosti využívá je zisťovanie sily ohybu stebiel prístrojom podl’a AO 18 15 83, ktorého princip spočívá v bočnom zaťažovaní vybratého počtu stebiel v poraste pod klasami. Táto metoda má radu nevýhod. Přístroj aj cez svoju velkost’ nemóže spoTahlivo hodnotit’ pevnost’ stébla najma pri vyšších porastoch kukuřice. Meranie týmto prístrojom je vizuálně, 0 nedostatku horeuvedených metod svědčí tiež Statisticky významný vplyv lokality, keď pri porovnaní rovnakých hybridov na róznych lokalitách sú výsledky velVni rozdielne často neporovná tel’né.The evaluation of the stalk strength and the selection of the appropriate material are currently characterized by visual methods that subjective evaluation of this trait. Stalk strength is incorrectly expressed by the percentage of broken plants under the lobster or ear, which is currently used is to determine the bending strength of the stalks by the apparatus according to AO 18 15 83, whose principle consists in lateral loading of a selected number of stalks in the stand . This method has a number of disadvantages. Despite its size, the device cannot reliably assess the 'strength' of the stalks, especially in higher corn crops. Measurement by this instrument is visually, the lack of the above methods is also evidenced by the statistically significant impact of the site, when comparing the same hybrids at different sites, the results are very often inconsistent.

Vyššie uvedené nedostatky sú odstránené prístrojom podl%i vynálezu, ktorého podstatou je, že pozostáva z pevného puzdra, * v ktorom je uložená posuvná tlačná tyčka opatřená na jednom konci tlačnou pružinou a spojenou s vychylovacím ramienkom re' gistrátóra sub na druhom konci s tlačnou ihlou.The above drawbacks are overcome by an apparatus according to the invention, which consists of a rigid housing in which a sliding push rod is provided with a compression spring at one end and connected to the deflection arm of the sub-register at the other end with a compression needle .

Využitím prístroja v praxi sa získavajú přesné číselné úda je v jednotkách SI, ktoré nie sú významnéjšie ovplyvňované lokalitou pestovania, čo v porovnaní s doterajšimi metodami umožní dokonale jšie hodnotenie a tvorbu zdrojov pre šl’achtenie obil nín najma kukuřice. Metoda merania sa značné urcýhli a uTahčí prácu. V krátkom čase možno zmerať veTký počet vzoriek, Nenároč nosť obsluhy a malé rozměry prístroja umožňujú prevádzať merania priamo v poraste, Hodnotenie materiálu možno posunut’ do ob231 278 dobia mimo pracovnú špičku, čím je umožněné šetrenie pracovných sil v době zberu.By using the instrument in practice, accurate numerical data are obtained in SI units that are not significantly influenced by the site of cultivation, which, compared to the previous methods, will allow a more complete evaluation and creation of resources for breeding cereals, in particular maize. The measurement method has been greatly simplified and made easier. In a short time, a large number of samples can be measured, the operator's ease of use and the small size of the instrument allow measurements to be carried out directly in the stand. Material evaluation can be shifted to off-peak hours to save labor at harvest time.

Na priloženom výkrese je znázorněné příkladné prevedenie prístroja na meranie pevnosti stébla v priečnom řeze.The accompanying drawing shows an exemplary embodiment of a device for measuring the stalk strength in cross-section.

Přístroj ^pozostáva z pevného puzdra 1^ v ktorom je v klzných ložiskách 11 uložená posuvná tlačná tyčka 2, Na drihom 1 X, *** konci 7 má posuvná tlačná tyčka“inštalovanú klieštinu 9 pre uchytenie vymeniteinej tlačnéj ihly 10. Jeden koniec 2 posuvnéj tlačnej tyčky 2_ s nasunutou tlačnou pružinou k je spojený s vychylovacím ramienkom 5 registrátora 6» Registrátor 6 je uchytený na pevnom puzdre 1»The device consists of a solid-casing 1 ^ wherein the slide bearings 11 displaceably mounted push-rod 2 on one drihom X *** end 7 has a sliding push-rod "Installed tie 9 for fitting a compression vymeniteinej needle 10. One end of the slider 2 of the push rod 2 with the push spring pushed on k is connected to the deflection arm 5 of the register 6 »The register 6 is mounted on a fixed housing 1»

Pri meraní sa vyvíja tlaková sila tlačnou ihlou 10 na sklerenchymatické pletivo neznázorněného stébla, pričom posuvná tlačná tyčka <2 tlačí na vychylovacie ramienko 5 registrátora 6 a vychyl’uje ukazovatel' 13« Po přelomení stébla tlačná pružina 4 vrátí tlačná ihlu 10 do póvodnej polohy» Ukazovatď 13 ostává na určitej hodnotě číselníka 12. Registrátor _6 sa nuluje tlačítkom <8.During the measurement, a compressive force is exerted by a pressure needle 10 on the sclerenchymatic mesh of a stalk (not shown), wherein the push rod <2 presses the deflector arm 5 of the register 6 and deflects the indicator 13. The pointer 13 remains at a certain value of the dial 12. The register 6 is reset by the <8 button.

Nenáročnou výměnou tlačnej pružiny 4 a tlačnej ihly 10 s iným vhodným prieraerom resp. výměnou tlačnej ihly 10 za teleso iného tvaru je možné robit’ merania na fcóznych pol’nohospodárskych 1 kultárach. Přístroj je určený pre šl’achtitel’ov pri práci s vylučováním šl’achtitel’ského materiálu.By undemanding replacement of the compression spring 4 and the compression needle 10 with another suitable borehole resp. By replacing the pressure needle 10 with a body of a different shape, it is possible to make measurements on fictional agricultural 1 cultures. The device is designed for breeders when working with the exclusion of breeder material.
