摘要

為避免設施中因超量施用化學肥料，造成肥料及鹽分累積等問題之發生而影響設施蔬菜之產量與品質，因此進行設施蔬菜栽培合理之施肥量及方法之研究。由本研究之結果可以發現，埋管排水能有效降低設施土壤中鹽分的累積，並減少硝酸態氮的濃度，對降低鹽害及連作障礙有明顯的效果，且其效果隨著處理次數的增加而更為明顯。另外，透過土壤診斷結果之推薦量進行之施肥，其除具有避免過量施肥及減緩鹽分累積之效果外，並可節省成本及提高產量，所以應鼓勵農民多進行土壤診斷施肥。

The purpose of this study is improving the greenhouse vegetable fertilize to avoid the overdose fertilize make fertilizer accumulate. The result indicates the treatment of exclude water by pipe can reduce the damage of salinity and continuous cropping, because it can effective reduces the accumulation of soil salinity and lowers the concentration of NO3-N, and those effect of reduces the soil salinity was better by increase the frequency. Another result indicates the fertilizers by soil diagnose can avoid the overdose fertilize and slowest the salinity accumulate. So, the soil diagnose is helpful for farmer, because it can save the cost and enhance the yield.
