20.500.12556/DKUM-12257 NATANČNOST DOLOČANJA POZICIJE SADOVNJAKOV ZA POTREBE ZGODNJEGA NAPOVEDOVANJA PRIDELKOV JABOLK Precision of position determination in the orchards for early prediction of apple harvest UDK: 531.73:634.11:631.559:004(043.2)=863 V diplomskem delu smo preučevali natančnost določanja pozicije vzorčenja v sadovnjakih za potrebe zgodnjega napovedovanja pridelka jabolk s pomočjo dlančnika, ki ima vgrajen GPS sprejemnik. Pri delu smo si pomagali z javno dostopno bazo GERK, ki temelji na dejanskem stanju v naravi. Zgodnja in natančna napoved pridelka temelji na računalniškem štetju in merjenju plodov, vendar je v veliki meri odvisna od natančnosti podatkov v bazah. Leta 2009 smo iz registra kmetijskih gospodarstev pridobili 245 intenzivnih nasadov, ki reprezentativno opisujejo vzorec celotne populacije slovenskih nasadov jablan po zastopanosti sort, letniku sajenja in vzgojni obliki. Poskus je obsegal ročne meritve v nasadih z dlančnikom s programsko opremo FK mobile za dlančnik in FK PC aplikacijo za osebni računalnik. Sinhronizirane podatke s terena smo nato v laboratoriju na osebnem računalniku preverili v bazi GERK. Rezultati poizkusa so pokazali uporabnost pa tudi težave razvite programske opreme. Napačnih meritev je bilo 19,6%, kar je preveč za dovolj natančno zgodnjo napoved pridelka jabolk v Sloveniji. Pokazale so se možnosti za izboljšavo načina opravljanja meritev. The paperwork examines the accuracy determination of position pattern in the orchards for early prediction of apple harvest by means of the personal digital assistant with integrated GPS. At work we used the officially accessible base GERK that is based under natural environment conditions. The early and accurate harvest prediction is based upon the computer counting and measuring of fruits, however, it depends upon the accuracy of data in the base. In year 2009 we gained from the agricultural holding register 245 intensive plantations representing the sample of the whole population of slovenian apple plantations according to the species, the year of plantation and growing form. The experiment included manual measurments with the personal digital assistant equipped with FK mobile software and FK PC application. The synchronized data from the fieldwork were checked in the base GERK on the personal computer. The results of the experiment showed the applicabiltiy and the difficulties of the software. There were 19,6°% fail measurments which is too much for a sufficiently accurate early prediction of apple harvest in Slovenia. Possibilites for measuring improvements have been shown.
