不同年份草莓栽植密度對植株生長果實糖度及產量之影響

Effect of Plant Spacing on Growth, Sugar Content and Yield of Strawberry in Two Seasons

本試驗以8種不同栽植密度處理，於民國73年9月至75年4月在苗栗縣大湖鄉進行2年試驗，藉以探討對草莓春香品種植株生長、果實糖度、早期產量、總產量及相關性之影響，試驗結果顯示，植株之株寬、株高、葉數及果實糖度等，處理間差異均不顯著，生長前期之株寬、株高與早期產量呈負相關，而後期植株生長則與總產量呈正相關性，植株生長、果實糖度及產量，不同年度間呈類著之變異性，然而，密植處理可顯著提高早期產量與總產量。綜合兩年試驗結果，增加單位面積種植株數，宜亟推廣農民應用，以提高產量，增加收益。

A trial was conducted in Ta-Hu to determine the effect of plant spacing on the plant growth, sugar content and yields in strawberry cv. Harunoka from September 1984 to April 1986. The results showed that plant spacing had no effect on plant width, height, leaf number and sugar content. Plant width and height of early stage were negatively correlated with early yield. But the plant growth of late stage was positively correlated with the total yield. Annual variation in plant growth, sugar content and yield were noticed. It was showed that the dense planting could increase both the early and total yield. In order to increase the yield and net income, the dense planting method might be recommended to the strawberry growers.
