在日本有普通旱地與設施旱地之混合地區，茲將T用水地區之C地區（設施面積率62.7%）與D地區（設施面積率47.3%，實際上無普通旱地之種植，以設施面積100%之地區處理）為對象精密調查其灌漑水量需要實態，並說明在設施園藝用水利用之特性。特別對設施栽培水管理之一次灌水量，灌漑期距，連作障碍地，鹽分地之用水量等。進而說明年間使用水量，水利用之變動期別，水集中利用時間之狀況，調整池水之利用效率，調整池容暈等，就有關用水計畫或設施計畫之基礎諸因子予以調整。

Having investigated the actual condition of water demands for C-district (its percentage of house plantation is 62.7%) and D-district (that is 47.3%; yet, as original farms had not been planted, it was manipulated as 100%) of the T-irrigation area, which are mixed with original farms and house plantations, we attempted to explicate the characteristic of water demands on the house plant zones. In particular, a design value for irrigation of upland field like following items have been pigeonholed; the water management of house plantation (the amount of each irrigation, irrigation intervals, water demands for desalinization of sick soil etc.) the amount of yearly water demands, the pattern of fluctuations in monthly water demands, the condition of timely concentration of water demands, the efficiency of water demands in the farm pond, and the capacity of farm pond.
