摘要

畦面經覆蓋後，可緩和表土層土壤含水量與土壤溫度之極端變化，穩定蔬菜作物生育之表土環境，對甜椒之早期生育性狀具促進效果。而覆蓋效果顯著以春作較秋作為優，其中甜椒增產70%；分枝數增加連一倍以上；莖葉乾重增加33%。滴灌與溝灌對甜椒一般生育性狀之影響則差異不顯著。覆蓋使根系分布變淺，相同覆蓋下，溝灌處理者根垂直分布較滴灌處理者深。覆蓋與灌溉處理對根乾重則無顯著差異之影響。覆蓋處理對植株葉片無機養分微量元素有提高現象，但主要元素處理間則無顯著差異。

Mulching showed the advantage in reducing the extreamely variation in soil moisture and temperature which can stabilize the growth of vegetables. It enhenced the early growth of sweet pepper.Spring crop with mulching showed much better growth than fall crop in (1) plant height, number of branches, dry weight of stem, leaf and root , and plot yield of sweet pepper. In sweet pepper, dry weight of leaf and stem, fruit yield and number of branches increased 33, 70 and over 100%, respectively.There is no significant in plant growth between treatments using drip and furrow irrigation.Mulching induced shallow root distribution, furrow irrigation increased the depth of vertical root distribution. Dry weight of root was not significantly affected by mulching and irrigation.Mulching Showed the higher micro-element and non-significant in macro-elements on leaf nutrient concentration of sweet pepper.
