陳榮五 吳雪鉁

摘  要

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。


A Study on Measuring of Water Requirement of Irrigation by Tensiometer in Green Asparagus

Y. W. Chen and S. J. Wu

Summary

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.
