2. SLM技术的说明

2.1 技术简介

技术定义:

Leaving the trunk of a newly harvested banana standing beside a follower plant to provide nutrients and moisture especially during period of drought.

2.2 技术的详细说明

说明:

Traditionally, banana is cut at the base (ground level) during harvesting and the stem is used as mulch. This has been the practice of the banana plantations for many years. Lately however, it was found out by research that by leaving the trunk standing beside a follower plant, yield could be improved because the trunk contains nutrients and moisture which could be used by the succeeding plants. The banana crown is cut just below the fruit and the leaves used as mulch. After a few months the trunk disintegrates and decomposes and the follower plants grow unimpeded utilizing the nutrients and moisture contained in the decomposing trunk..
