摘要: 本試驗以”農友301”和”紅冠”品種番茄為試驗材料,番茄苗分別在海拔高度1700公尺之台一種苗繁殖場清境分場與平地海拔高度41公尺之上盛育苗場培育,分別於1998年9月及10月定植於臺南區農業改良場之試驗田內,進行不同海拔穴盤苗(高海拔、平地)和栽培密度(一穴栽1株,株距25公分、一穴栽1株,株距50公分、一穴栽2株,株距50公分)對兩品種生育及產量之影響。 “農友301”品種番茄穴盤苗定植時苗株調查結果顯示:高海拔所育之苗莖徑顯著較平地者粗,株高顯著較平地者較矮。9月定植之始花節位,高海拔及平地穴盤苗無顯著差異,10月定植之高海拔穴盤苗始花節位最低,平均約6.3節。“紅冠”品種番茄高海拔及平地穴盤苗苗株性狀比較結果如”農友301”品種。於9月及10月定植苗之始花節位,以高海拔穴盤苗較平地苗分別顯著降低1.2節及3.6節。 “農友301”品種番茄第2∼12週果實累計產量顯示總果數、平均單果重、總產量以10月定植者顯著大於9月者。高海拔苗於第2、4週採收之果數及產量顯著高於平地苗。第2週高海拔苗每小區(3平方公尺)果實產量達0.8公斤,至第4週累積到5.1公斤,而平地苗則由0.2公斤至2.9公斤。第4週以後育苗地點對產量影響差異不顯著。於三栽培密度中,採收後4週以一穴栽1株,株距25公分之果數顯著增加,果重及果實大小則沒有顯著差異,總產量則顯著較一穴栽1株,株距50公分者,每小區可增加2.8公斤。 “紅冠”品種番茄第2∼14週果實累計產量顯示總果數、平均單果重、總產量以10月定植者顯著大於9月者。於第2、4、6週採收高海拔苗植株之果數及產量顯著高於平地苗。第2、4週之平均單果重於二地區苗則差異不顯著,第4週以後平均單果重平地苗顯著大於高海拔苗。第2週高海拔苗每小區(3平方公尺)果實產量達0.3公斤,至第6週累積達9.7公斤,而平地苗則由0公斤至7.6公斤。第6週以後產量差異不顯著。一穴栽1株,株距25公分之栽培密度第6週果數及產量較另二栽培密度增加,總產量則顯著較一穴栽1株,株距50公分者,每小區可增加4.1公斤。
Tomato cultivars Known- You 301 and Red Crown were used in this study. Tomato seedling were grown in high and low elevations at ching- jing farm, Nantou and at Shang-sheng nursery, Chiayi, respectively. The seedlings, then, were transplanted twice into the plots at Tainan District Agricultural Improvement Station in September and October, 1998 with three different densities to evaluate seedling-growing condition and plant density on the growth and yield of tomato. Results of the cv. Known- You 301 indicated that the stem diameter of the seedling grown at high elevations is larger but shorter than that grown at low elevations. No significantly difference was observed in the node of flower initiation among the seedlings from high or low elevations and planted in September, while the seedlings planted in October, high elevations plants were found with 6.3 nodes lowest for flower initiation. On the cv. Red Crown, Seedling quality was found the same as cv. Known-You 301 ignoring the seedling grown elevations. Seedling grown at high elevations and transplanted in September and October were found with 1.2 and 3.6 nodes, respectively, lower of flower initiations than those cultivated at low elevations. On the cv. Known-You301. Data accumulation of the harvestings in 12 weeks. Total fruit numbers, average fruit weight, and total yield for the plants planted in October were higher than those planted in September. Plants from high elevations seedlings were higher yield and more fruits in the first 2 and 4 weeks of harvestings. The yield per 3m2 of plants from high elevations seedlings was 0.8 ㎏ in the first 2 weeks and accumulated to 5.1㎏ in the 4th weeks, while the of yield plants form low elevations seedling was from 0.2㎏ to 2.9㎏. Since then elevations of seedling raising did not significantly affect the yield. Among the plant densities tested, one plant at a planting hill and with 25㎝ between plants had the highest fruit number, however, no significantly difference was observed in fruit size and average fruit weight. The plot with one plant/25㎝/hill between plants produced 2.8㎏ more than that with on plant/50㎝/hill between plants planted in September or October. “Red Crown” tomato, plants planted in October were with higher yield, more fruits and larger average fruit weight than those planted in September in the first(2wks), 2nd(4wks)and 3rd(6wks)harvestings, total yield and fruit number from the seedlings grown at high elevations were higher than that from the low elevations seedling. Average fruit weight was no significantly difference between the seedling-raising elevations in the first and 2nd harvestings. After 4 weeks or after the 2nd harvesting, average fruit weight from the low elevations seedlings was larger than that from the high elevations seedlings. The yield of plants from high elevations seedling in each experimental units was 0.3㎏ of fruit in the first 2 weeks and accumulated to 9.7㎏ in the 6th weeks, but the yield of plants from low elevations seedlings was from 0 to 7.6㎏. No significantly difference was observed in yield after 6 weeks. Among the three densities, yield of the treatment with one plant / hill was the highest than the other two. The plot with one plant/25㎝/hill between plants produced 4.1㎏ more than that with on plant/50㎝/hill between plants in September or October.
