Description

The purpose of this paper was to clarify the effects of planting hole diameters of mulch film and plant coverage on soil temperature beneath mulch film. At both 6:00 and 15:00, the soil temperature in mulched zones decreased more when the plant coverage was higher and the soil temperature in the control zone (bare plot) was higher. No significant difference, however, was observed between zones with different planting hole diameters. The soil temperature differences between zones are significantly affected by air temperature, soil moisture tension and plant coverage. In vegetation zones, the daily range ratio of the soil temperature was the smallest in the zone with 3 cm diameter planting holes (Mp3). The daily range ratio of soil temperature in all vegetation zones, except the Mp3 zone, was affected by three factors: daily average air temperature, daily total amount of solar radiation and daily average wind speed.

本実験の目的は、フィルムマルチ下地温に及ぼす影響をフィルム植穴径と植被率との関係から明らかにすることである。6時地温と15時地温ともに、対照区(裸地)地温が上昇して植被率が高くなるほど各区の地温は低下したが、植穴径による明瞭な差はみられなかった。地温日較差比について各植被率下では、植穴3cmの区(Mp3)が最も比が小さくなった。また各植被率下の地温日較差比については、Mp3区以外の区は日平均気温、日射量日総量、日平均風速の3要因が共通して影響を及ぼした。
