Abstract
本研究綜合檢討9處矽酸爐渣連用試驗經歷5年（10作）及1處矽酸爐渣、稻藁連用試驗歷經6 1/2年（13作水稻）之收量結果，並分析矽酸爐渣之連用對土壤化學性質之影響。
試驗地點分佈西部各縣、土壤均屬酸性，9處矽酸爐渣連用試驗之處理爲(1)對照區；不施矽酸爐渣，(2)矽酸爐渣每期作每公頃1.5公噸，(3)矽酸爐渣每期作每公頃3公噸，但自第7作（69年第二期作）起將(2)及(3)處理各分爲二半，一半繼續施用矽酸爐渣（照原量），另一半則停施以觀矽酸爐渣之殘效及續施效果。另一處矽酸爐渣，稻藁連用試驗則以稻藁之掩埋與否（即稻藁每期作每公頃0及5公噸）爲主處理，矽酸爐渣之施用與否（即爐渣每期作每公頃0及2公噸）爲副處理，亦自第7作起以試驗田之一半停施矽酸爐渣以觀殘效。以上試驗各處理區，均依標準施肥法施用足量之三要素肥料。Field experiments have been carried out island-wide at 9 paddy locations on acid soils for 5 years (10 crops) using 3 treatments (1) check; no siliceous slag applied, (2) siliceous slag applied at the rate of 1.5t/ha/crop, and (3) siliceous slag applied at the rate of 3t/ha/crop. Nitrogen, phosphate and potash were amply applied to all of the test plots following the stantard recommended method. A randomized block design with two replications was adopted as the experimental procedure.
Beginning with the 7th crop, the plots with treatment (2) and (3) were each divided into two. One half of the plots received continuous siliceous slag applications while on the other, the application was interrupted, so that both the residual effect and the effect of continuous application could be observed.
Another experiment with and without the application of straw (0 and 5t/ha/crop, respectively) as primary treatment, and with and without siliceous slag (0 and 2t/ha/crop, respectively) as subtreatment was also conducted at one location for 61/2 years (13 crops) Application of siliceous slag on half of these pltos was also interrupted beginning with the 7th crop for the same reason as above.
