水旱芋栽培敷蓋處理對田間雜草控制的影響

本試驗以檳榔心芋為試驗材料，田區規劃分為水田栽培與旱田栽培，於2013年12月(冬作)與2014年3月(春作)種植於雲林縣林內鄉農田，探討蔗渣、稻殼與花生殼三種敷蓋的雜草管理模式對雜草控制的影響。試驗結果如下:敷蓋處理對芋田間雜草抑制的效果，以敷蓋稻殼處理對水芋及旱芋、冬作及春作芋田間雜草族群皆有顯著的抑制效果，在生育期(60天、120天、180天與240天)之4次調查中皆有最低之雜草密度與乾重，而未敷蓋之對照組則於生育期間大都有最高之雜草密度與乾重。水芋因田間經常保持湛水，雜草不易萌芽生長，雜草抑制效果較旱芋佳。冬作與春作之水芋與旱芋田間雜草族群相皆以莎草科(Cyperaceae)、禾本科(Gramineae)、茜草科(Rubiaceae)與菊科(Compositae)為多數之雜草物種。且在期作與水旱芋間雜草相之差異並不大。

In this experiment, taro (Colocasia esculenta(L.)Schott) as materials, Planning is divided into lowland and upland cultivation, The planting of three kinds of sugar cane waste, rice husk and peanut shell both in lowland and upland cultivation in Linnei Township of Yunlin County in December 2013 (winter crop) and March 2014. (spring crop) The impact of weed management on weed control. The results show: The results showed that the treatment of laying canopy had a significant inhibitory effect on the weed population in the fields of taro, taro and winter as well as in the field of spring taro. During the growth period (60 days and 120 days , 180 days and 240 days) all had the lowest weed density and dry weight in the four surveys, while the control group that had not been covered had the lowest weed density and dry weight during the growing period. Calla lily water often because of field maintenance, weeds are not easy to sprout growth, weeds inhibit the effect of drought better. The main weed population of lowland field and upland field in spring and winter crop were Cyperaceae、 Gramineae、Rubiaceae and Compositae.. And the crop and taro lowland and upland the phase of the weeds is not as big.
