摘要

為瞭解桃園區落花生主要產區之最適播種期與栽培密度，以供栽培者做為產期調節之參考。供試品種為台農4號，試驗期間在77年二期作及78年一期作，試驗地點在竹南、後龍及新屋三鄉鎮，試驗處理，分五個播種期及三種密度。77年二期作試驗結果：播種期在三地區均以7月16日播種的公頃鮮莢產量最高，依次為7月1日、8月1日。栽培密度試驗在竹南及後龍均以密植（30 × 6公分）之鮮莢產量最高；而新屋地區之栽培密度對產量影響並不顯著。78年一期作試驗結果：播種期在竹南及後龍均以3月25日播種的鮮夾產量最高，依次為3月10日，2月25日。新屋則以3月10日播種者最高，依次為3月25日、2月25日。栽培密度試驗結果，竹南以中密植（30 × 10公分）及密植（30 × 6公分）之產量較高，後龍栽培密度對鮮莢產量影響不顯著，新屋以寬植（30 × 14公分）及中密植（30 × 10公分）之產量較高。

In order to find the optimal sowing date and planting density of table-use peanut. An experiment was performed at three locations in northern part of Taiwan from the second crop of 1988 to the first crop of 1989. A split-plot design with 5 sowing dates as mainplot and 3 planting densities as subpolt in four replications was adopted. The results were summaryed as followed:1. In the second crop of 1988. The suitable sowing dates were from July 1 to August 1 at three locations. The Peanut which sown on July 1 yielded the highest fresh pods (4151-4225 kg/ha) which increased 24.0%~49.8% more than those of the last planted (Sown on September 1) whereas planted with closed spacing (30 × 6cm) yielded the highest at Chunan and Houlung. However, the effect of planting densities on yield of fresh pods is not significantly different at 5% level at Hsinwu.2. In the first crop of 1989. The suitable sowing dates were from March 10 to March 25. Peaut which sown on March 25 at Chunan and Houlung yielded the highest fresh pods (4279.2 and 4925 kg.ha) which increased (19.9% and 31.8%) more than those of the last planted (sown on April 25). Whereas at Hsinwu sown on March 10 gave the highest yield (4225.0 kg/ha) which increased 16.8% more than that of the last planted. Peanut which sown at Chunan with wide spacing (30 × 144cm) gave the lowest yield (4095.0 kg/ha) which decreased 3.9% less than that of the check spacing. At Hsinwu, planted with close spacing yield the lowest fresh pods (3637.5) which decreasd 4.9% less than that of the check spacing. However, the effect of planting density on yield of fresh pods is not significantly different at 5% level at Houlung.
