Abstract

This Experiment was conducted to determine the effects of light shield materials when melon grown inside a plastic greenhouse in summer season. The average temperatures were 36.6℃, 34.5℃ and 34.0℃ respectively for the control(non-shield), coating agent, and the white net. The light transmittances were 69% and 75%, respectively inside the greenhouse treated with the coating agent and white net immediately after applicants, compared with that inside the control greenhouse. At the 40 and 80 days after treatment, the light transmittances for the coating agent were 92% and 98%, respectively, indicating it was slowly decomposed and removed, but there was no change in the transmittance for the white net. While the leaf number did not differ among the treatments, the plant height was higher in the white net and shading agent than in control. The weight of the leaves, fresh-weight and dry-weight were no different from that of shading, but it became heavier in the later stages. The marketable fruit yield was increased by 6% for white nets and 5% for the coating agent compared to control, there was no statistical significance. Therefore, coating agent is considered as an effective method to lower temperature during high temperature period, but it is preferable to use it in consideration of cultivation period, because the coating agent is gradually removed.

고온기 시설멜론 재배 시 저비용 고효율의 개발하기 위하여 차광 자재별 이용 효과를 구명하고자 수행하였다. 차광처리에 따른평균온도는 무차광이 36.6℃, 차광도포제는 34.5℃, 백색차광망은 34℃로 조사되었다. 도포제 살포 직후에 투광률이 무차광에 비해서 차광 도포제 처리구는 69%, 백색차광망 처리구는 75% 이었으나, 40일 및 80일 후 차광 도포제 처리구의 투광률이 각각 92% 및 98%로 높아져 처리된 차광도포제가 서서히 제거되는 것을 알 수 있었으며, 백색차광망 처리구는 시간의 경과에 따른 투광률의 변화가 거의 없었다. 생육에 있어 엽수는 처리 간에 차이가 없었고, 초장은 무차광에 비해 백색차광망과 차광도포제 처리구에서 높게 나타났다. 엽중, 생체중, 건물중의 경우 차광 처리구에 비해서 무차광에서 정식 42일 후에는 더 무거운 것으로 나타났다. 총 상품수량은 무차광에 비해서 백색차광망과 차광도포제가 각각 6% 및 5% 증수되었다. 따라서 고온기 간편하게 온도를 낮출수 있는 방법으로 차광도포제는 효과적이나 서서히 제거되기 때문에 재배 시기를 고려해서 사용하는 것이 바람직하다고 생각되었다.
