香蕉灌溉試驗初報

The Irrigation on Banana

（一）香蕉灌水之週次及水量之多少有增高植株之效果，對增大莖組似不明顯。（二）香蕉灌水之次數較灌水之量更為重要。（三）香蕉灌溉次數相隔愈近，少量灌水較多量灌水為優。（四）香蕉二週灌水一次較三週灌水一次為佳，二週灌40公厘又較灌60公厘為優。（五）香蕉灌水可維持青葉數及新葉生長。（六）香蕉灌水可以促進提早抽穗。

This work was carried out from 1964 to 1967 but the first design of the number of irrigation and amount of water are divided into 20, 40, 60 mm. by one week, and 20, 40, 60, 60, l00 mm, by three weeks, Because of the range of the degree to irrigated which it is too dense then change the design from 1966 that gave the frequency of irrigation divided by 2 and 3 weeks and the amount of water divided by 40 mm, and 60 mm, 2×2 treatments and 6 repelication for the result of brief as follow: 1. It is efficiency of increasing of height of plant by number of irrigation and amount of water by increasing the diameter of the stem is same no different. 2, It is so important of the frequency of irrigation than the amount of water on banana irrigation. 3. A little amount of water is better than more amount of water When the interval of time of irrigation is more nearly. 4, One time of irrigation by two weeks is better than three weeks of irrigation but 40 mm, of two weeks is better than 60 mm. 5. The relation between of irrigation to the leaves which not only could be protected the number of green leaves but also developing the growth of new leaves meanwhile, may be promoting early inflorescence of plant.
