利用Tensiometer測定綠蘆筍需水量之研究

Abstract

本試驗結果以對照區之每七～十天灌水一次，每次灌水量40mm之處理為最好，再次為保持PF1.8～2.3之處理，水分太少時則植株生育受影響，其產量亦低。 The water requirement for irrigation in green asparagus per 7~10 days one time for irrigation, the quantities of irrigated water is 40 mm, which is best for increasing yields of green asparagus. Next was a treatment of maintaining pH 1.8~2.3. The B, C, D treatments, which used less irrigated water, therefore the yields were decreasing.
