1. 이탈리안 라이그라스의 코팅종자 제조시 접착제는 PVA가 유리하였으며 2~5% 내에서는 큰 차이가 없어 경제적으로 판단했을 경우에는 2%가 유리하다. 2. 탄산칼슘+탈크를 활용하여 종자 코팅하는 것이 천립중, 리터중이 높고 매끄럽게 성형되어 유리하였으며, pH와 EC가타 피복제에 비해 낮아 화학적으로 안전하였으며, 발아세, 평균발아속도가 높아 타 피복제에 비해 우수하였다. 3. 탄산칼슘+탈크를 무게에 따라 코팅하여 비교했을 시, 대조구에 비해 발아율, 발아세, 평균 발아 속도에서 초장 차이를 보이지 않았으며, 강도는 피복 재료와 종자와의 무게 비율 1:1과 그 이상 무게를 추가할 경우에는 차이를 보이지 않아 경제성을 고려하였을 때 1:1이 가장 유리하였다.

Abstract ▼ AI-Helper

This study was conducted to determine an appropriate coating method for mechanized sowing of small and light Italian ryegrass seeds. In the case of manufacturing coated seeds, 2% PVA was superior as an adhesive compared to PVP and Tween80. Calcium carbonate + talc adhered to the seeds smoothly and well and the seed weight was higher than that of the other coating materials. The germination percentage of seeds coated with calcium carbonate + talc was 95.8%, which was not significantly different from 96.5% of the control group, but the mean daily germination was the highest. As the coverage ratio of calcium carbonate + talc increased, the strength tended to increase when coated at 1.5 times the seed weight. There was no difference in the germination rate and plant height compared to the control group according to the coverage ratio.
