Abstract

Organic fertilizer preparation was developed with organic materials to improve growth and qualities of cool-season turfgrass species. Organic fertilizer preparation were contained with essential macronutrient elements and organic matter for growth of cool season turfgrass. Four preparations of organic fertilizers were tested on creeping bentgrass (Agrostis palustris Huds) cultivar Penn-A1 and Kentucky bluegrass (Poa pratensis L.) mixed cultivars (Midnight 33%, Moonlight 33%, and Prosperity 33%) by one time application on fifty days after sowing. Two species of cool season turfgrasses were evaluated on turfgrass coverage, growth on NDVI (Normalized Difference Vegetation Index) and qualities from fall season to spring season in sod producing farm. It were found significantly difference found on turfgrass coverage, turf color, chlorophyll contents and growth increase on two species of cool season turfgrasses. Turfgrass coverage, chlorophyll content, turf color and growth increase of organic fertilizer preparation were significantly increased on creeping bentgrass cultivar and Kentucky bluegrass mixed cultivar for six time investigation in spring season. These results may indicate that the use of some preparation is beneficial for sod producing sod and turfgrass management.

유기질비료의 원료를 이용하여 한지형 잔디의 종자 파종후 피복율, 생육 및 질의 증진을 위한 유지질비료 제제를 개발하였다. 개발 제제는 한지형 잔디의 생육에 필수적인 무기영양소와 유기물을 함유하고 있다. 유기질비료로 개발한 제제는 4종류로 creeping bentgrass "Penn-A1" 품종과 Kentucky bluegrass 혼합품종(Midnight 33%, Moonlight 33%와 Prosperity 33%)의 종자를 파종 후 50일에 1회 토양 시비로 시험하였다. creeping bentgrass와 Kentucky bluegrass의 피복율, 생장(생장지수) 및 잔디의 질은 2013년 가을부터 2014년 봄철기간 동안 경시적으로 평가를 하였다. 개발제제의 파종 후 1회 토양살포로 잔디 피복율, 잔디 엽색, 엽록소 함량 및 생장에서 통계적인 유의성의 차이를 보였다. creeping bentgrass와 Kentucky bluegrass의 피복율, 엽록소 함량, 잔디 엽색 및 생장은 봄철 6회 조사까지 통계적으로 유의성 있게 증가하였다. 이 결과에 의하면 일부 개발 제제의 사용은 한자형 잔디의 뗏장잔디의 생산과 잔디관리에 도움의 줄 것으로 생각한다.
