Abstract
本試驗為明瞭不同種類之PE塑膠布在鳳梨園敷蓋之效果。在乾旱季節，PE布敷蓋區之土壤水分含量較稻草敷蓋及無敷蓋區為高，尤以表上部分為甚。在鳳梨植株發育初期，PE布敷蓋區土壤溫度較稻草敷蓋區高出甚多，如在晴天午後時可提高5~7℃以上。PE布敷蓋對雜草之發生雖有抑制效果，但僅爲稻草敷蓋區之一半，且以黑色PE布效果較佳。秋植鳳梨之生長情形遠較稻草敷蓋及無敷蓋區爲佳，產量亦高。但春植鳳梨則植株之生育情形及產量增色以稻草敷蓋區爲佳。秋植時宜採用黑色0.04 mm厚度之PE布代替稻草敷蓋，以促進鳳梨之生長及提高產量，但春植時則不宜用PE而敷蓋，仍以稻草敷蓋爲宜。
1. The purpose of this experiment is to understand the effectiveness of using different kinds of PE film for mulching on the pineapple field. Three different colors of PE film, i.e., black, light black and gray; and each color film with 0.04 mm and 0.05 mm in thickness were used for mulching. Straw mulching and without mulching treatments were used as cheek. This experiment was carried out in Feng-shan, Hsin-hwa and Chia-yi from Oct. 1968 to Dec. 1971.
2. The result showed that the soil moisture (especially the soil surface) content in the PE mulching plots was higher than check during dry season.
3. Soil temperatures which varied from 5°to 7℃ higher than straw mulching plot were recorded in the PE mulching plots when the pineapple plants were young.
4. Black PE film was found to be more durable than light black and gray films. The latter two only lasted for 6 months and even shorter in the spring planted crop plots. The thicker (0.05 mm) film was only slight durable than the thinner one (0.04 mm film).
5. For weed control, straw mulching was found to be more effective than PE mulching. And among PE films, black film showed better result.
6. It was found that the fall planted crop showed much better pineapple growth than the check, and this might due to the soil moisture and temperature were better maintained by the PE films, But the best growth and yield of the spring planted crop were found to be in the straw mulching plots.
7. In conclusion, 0.04 mm black PE film mulching is suggested to substitute, the traditional straw mulching for fall planted crop. But for spring planted crop, straw mulching is still recommended.
