Abstract

„Bioraznolikost” je riječ koju se koristi kako bismo istaknuli bogatstvo prirodnog svijeta. Ona je u konstantnom opadanju na poljoprivrednim površinama diljem Europe i njezina zaštita zahtjeva poseban interes. Razlozi smanjenja bioraznolikosti su intenziviranje poljoprivredne proizvodnje i napuštanje marginalnih poljoprivrednih područja. Sve brži i napredniji razvoj poljoprivredne proizvodnje uključuje povećano korištenje herbicida, ostalih pesticida i gnojiva, a to ima trenutne i dugoročne posljedice za brojne biljne i životinjske zajednice. Cilj ovog istraživanja je utvrditi brojnost i vrste oprašivača na području usjeva uljane buče sa cvjetnim pojasom i usporediti broj prisutnih oprašivača na području uljane buče bez cvjetnog pojasa te utvrditi utjecaj oprašivača na prinos uljane buče. Cvjetni pojas je posijan na lokalitetu Šašinovec. Unutar pojasa određena su tri područja površine 3x3 m koja su se fotografirala te se napravila procjena cvatućih biljaka prema porodicama: Apiaceae, Asteraceae, Brassicaceae, Fabaceae, Lamiaceae, te ostalo samoniklo bilje. Postotak cvatućih biljaka unutar navedenih porodica bilježen je prema zadanoj skali. Praćene su određene porodice oprašivača te je zabilježen broj prisutne faune u tri ponavljanja. Očitavanja su se provodila u razdoblju od lipnja do kolovoza. Tijekom očitavanja uzorkovanjem 4 biljke u 4 ponavljanja u prva 4 reda na dijelu usjeva uljane buče sa i bez cvjetnog pojasa bilježio se broj i masa plodova uljane buče po biljci. Zabilježen je veći prosječan broj i veća prosječna masa plodova po biljci na dijelu usjeva uljane buče sa cvjetnim pojasom u odnosu na dio usjeva uljane buče bez cvjetnog pojasa. Može se zaključiti da cvjetni pojasevi imaju pozitivan učinak na bioraznolikost, brojnost oprašivača te na prinos uljane buče pa se zbog toga smatraju pouzdanom i korisnom agro-okolišnom mjerom.

Abstract (english)

"Biodiversity" is the word used to emphasize the richness of the natural world. Biodiversity is steadily declining on agricultural areas across Europe and its protection requires special interest. Reasons for reducing biodiversity are intensification of agricultural production and abandonment marginal agricultural areas. The faster and more advanced development of agricultural production involves the increased utilization of herbicides, other pesticides and fertilizers, which has immediate and long-term consequences for numerous plant and animal communities. The aim of the research was to determine the number and type of pollinators in the field of oilseed squash with a floral belt and to compare the number of pollinators present in the area of oilseed squash without floral belt and to determine the influence of the pollinators on the yield of oilseed squash. The flower belt is sown on the locality of Šašinovec. Within the belt, three areas of 3x3 m area were photographed and an evaluation of the flowering plants was made for families: Apiaceae, Asteraceae, Brassicaceae, Fabaceae, Lamiaceae, and other self-propagating herbs. The percentage of flowering plants within the mentioned families was recorded according to the given scale. Certain families of pollinators were monitored and the number of fauna present was recorded in three repetitions. The readings were conducted in the period from June to August. During the sampling of 4 plants in 4 repetitions in the first 4 rows on the part of the crop of oilseed squash with and without floral belt recorded was the number and mass of the fruits of oilseed squash. There is a higher average number and a higher average mass of fruits per plant on the part of the oilseed squash with floral belt in relation to the part of the oilseed squash without floral belt. We can conclude that flower belts have a positive effect on the variety of pollinators and the yield of oilseed squash and are therefore considered a reliable and useful agro-environment measure.
