Abstract :本学術報告16号14頁に図示し, 前報キュウリの施肥試験で補足説明したベッド3つを用いてキュウリに対する給水量試験を行った。品種, 栽培期間, 播種法は前報と同じである。肥料は各ベッドに住友液肥2号(10-5-8)を週1回80ccずつ入れた。水はA, B, Cベッドにそれぞれ毎日, 2日に1回, 3日に1回ずつ貯水管の容量32ℓに満たした。結果は第1表と第1図に示した。消費水量, 早期収量, 総収量ともA>B>Cの順であった。キュウリは過湿にならない限り給水量は多い方がよく, とくに果実の肥大に対し敏感であった。
Three beds as shown in page 14 of the Science Bulletin (No. 16,1969) and supplementally explained in the preceeding paper were used to find the proper frequency of water supply to cucumber. Variety, period of cultivation, and the method of sowing were the same as mentioned in the preceeding paper. Eighty (80) ml of Sumitomo Ekihi No.2 (10-5-8) were put into the water-storage pipe of each bed once every week. Water was supplied every day, every other day, and once in 3 days to A, B, and C beds respectively to fill the capacity of the water-storage pipes (32l). Results are shown in Table 1 and Fig. 1. Water loss, early harvest, and total harvest of fruits were in the order of A, B, and C beds. It is considered that cucumber requires abundant water supply.
