中文摘要 | 利用有機質肥料、消石灰及不同型態鉀肥等處理,探討對減輕青蔥栽培連作障礙及葉尖枯萎發生之成效,試驗處理分別為三要素區(N:P:K=180:170:160kg/ha)有機質肥料10t/ha(N:P:K=126:168:140kg/ha)+不足之NPK用量(54-2-20kg/ha)三要素區+有機質肥料10t/ha三要素區+N:P:K=126:168:140kg/ha(有機質肥料10t/ha所含肥料量)三要素區+消石灰2t/ha三要素區其中KCI改用K2SO4但鉀量相同等共六處理。由民國80年7月至82年6月之試驗結果得知,夏作不論80、81年產量均以施用有機質肥料10t/ha+不足之NPK用量(54-2-20kg/ha)處理之青蔥產量最高,較對照區(三要素區)分別增產7.5﹪及11.3﹪,其次為三要素+消石灰2t/ha之處理。秋作均以三要素+有機質肥料10t/ha之處理最高,分別較對照區增產4.8﹪及5.0﹪。春作均以三要素+消石灰2t/ha之處理最高,分別較對照區增產11.7﹪及20.4﹪。葉尖枯萎情形綜合二年來試驗調查結果顯示,不論是夏作、秋作及春作各處理間葉尖枯萎程度均有極顯著的差異,而以施用有機質肥料或增施消石灰的處理最為輕微,其原因可能係原土壤過酸,經添加具有鈣成分的有機質肥料或消石灰而提高土壤pH值所致,另比較施用氯化鉀的三要素區與施用硫酸鉀的三要素區其中KCI改用K2SO4但鉀量相同,其葉尖白化枯萎的程度,不論夏作、秋作及春作均無顯著差異,由此可知葉尖枯萎與氯的施用無關,導致青蔥葉尖白化枯萎的原因尚待進一步探討。 |
英文摘要 | In order to decrease the stress of continuous cropping and tip blight leaf of green onion, the experiment was conducted for using organic manure、lime hydrate and different type of potassiume. The experiment was distributed in six treatments, which were (1) NPK( N 180- P O 170-K O 160), (2) Organic manure, (3)NPK+ organic manure 10t/ha, (4) NPK+N 126-P O 168-K O 140(organic maunre), (5)NPK+ lime hydrate 2t/ha, (6)NPK (KCI substituted with K SO ) from july, 1991to june, 1993. The results showed that the organic manure 10t/ha added NPK(54-2-20kg/ha) plot got higher yield by 7.5 and 11.3% than check in summer, while the NPK+ organic manure 10t/ha plot were enhanced 4.8 and 5.0% in autumn respectively, and NPK + lime hydrate 2t/ha plot had increase 11.7 and 20.4% in spring. On the other hand, the application of organic manure of lime hydrate had less leaf tip blight. The reslues suggest that the application of calcium component with organic manure or lime hydrate could promote the soil pH value and reduce the percentage of leaf apex wilt. |
