초록
This study was conducted to evaluate the appropriate sowing method and mixture seeding rate on germination of Kentucky bluegrass (Poa pratensis L.) and white clover (Trifolium repens L.). The experimental design includes two sowing methods and six mixed seeding per each method: BT1:BP0 (broadcast seeding; B, Trifolium repens; T, Poa pratensis; P), BT1:BP2, BT1:BP3, BT3:BT1, BT2:BP1, BT0:BP1 and ST1:SP0 (spot seeding; S), ST1:SP2, ST1:SP3, ST3:ST1, ST2:SP1, ST0:SP1. The germination was the highest for both species when the seeding rate was higher than other species. In overall, the germination of white clover was higher and faster than Kentucky bluegrass. Two plots, BT2:BP1, ST1:ST2, were retained the balanced proportion of the germination rate. Therefore, It was suggested, for maintaining the balanced field, it is better to seed white clover twice Kentucky bluegrass on broadcast seeding and Kentucky bluegrass twice white clover on spot seeding. In regard of sowing method, broadcast seeding is better than spot seeding in terms of increasing the germination. It is necessary to supplement the result for real application by long-term monitoring.
Abstract
This study was conducted to evaluate the appropriate sowing method and mixture seeding rate on germination of Kentucky bluegrass (Poa pratensis L.) and white clover (Trifolium repens L.). The experimental design includes two sowing methods and six mixed seeding per each method: BT1:BP0 (broadcast seeding; B, Trifolium repens; T, Poa pratensis; P), BT1:BP2, BT1:BP3, BT3:BT1, BT2:BP1, BT0:BP1 and ST1:SP0 (spot seeding; S), ST1:SP2, ST1:SP3, ST3:ST1, ST2:SP1, ST0:SP1. The germination was the highest for both species when the seeding rate was higher than other species. In overall, the germination of white clover was higher and faster than Kentucky bluegrass. Two plots, BT2:BP1, ST1:ST2, were retained the balanced proportion of the germination rate. Therefore, It was suggested, for maintaining the balanced field, it is better to seed white clover twice Kentucky bluegrass on broadcast seeding and Kentucky bluegrass twice white clover on spot seeding. In regard of sowing method, broadcast seeding is better than spot seeding in terms of increasing the germination. It is necessary to supplement the result for real application by long-term monitoring.
