中文摘要 | 為探討不同栽培密度對大小粒型落花生品種產量及生長特性之影響, 乃於1991年秋作及1992年春作以大粒型品種台南11號及小粒型品種台南選9 號在行距35公分,株距12、10及8公分(不作畦)三種密度下進行試驗,結果發 現兩個品種在春作之單位面積莢果產量隨密度之提高而增加,秋作產量則與密度 反應不一致;春作產量高於秋作產量。兩個品種在春作以密植有較大之乾物質生 產量,但秋作三種栽植密度則相若;就CGR而言,三種密度間無明顯差異,但春 作均大於秋作。 在秋作時,三種栽植密度之LAI與ULR在品種間之差異不顯著,但在春作密植 時有較大LAI。此外,品種在秋作、春作之莢果加權平均充實速率,三種栽植密 度間無明顯差異,一般春作亦大於秋作。 |
英文摘要 | For determining the effects of plant density on pod yield and drymatter production of peanut cultivars. Two cultivars TNiKlarge kerneltype) and TNS 9 (small kernel type) seeded in 35cm rows with three intrarow spacings of 12,10 and 8 cm were used in the fall crop of 1991 andspring crop of 1992. Results showed that pod yield per unit land area oftwo cultivars, TNII and TNS9 were increased with increasing plant density in spring crop season. But were not increased with increasing plantdensity in fall crop season. For pod yield, peanut grown in spring cropseason was higher than that of fall crop season. Dry matter production oftwo cultivars increased with increasing plant density in spring cropseason. However, no significant difference was found amonng 3 spacings in fallcrop season. Higher crop growth rate was found in spring crop season intwo cultivars. LAI and ULR of two cultivars did not different among plant density infall crop season, LAI of two cultivars increased with increasing plantdensity in spring crop season. Mean wighted pod filling rate of twocultivars was not different among planting density in fall and spring cropseason, The mean weighted pod filling rate of two cultivars grown in thespring crop season was higher than that of fall crop season. |
