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..

5.1 气候

5.2 地形

关于地形的注释和进一步规范:

Altitudinal zone: 0-100 m a.s.l. (Banana plantations are in the lowland)
Landforms: plateau/plains (Mostly coastal and alluvial plains)
Slopes: flat and gentle (All commercial banana plantations are on level land)

5.3 土壤

如有可能，附上完整的土壤描述或具体说明可用的信息，例如土壤类型、土壤酸碱度、阳离子交换能力、氮、盐度等。:

Soil depth: very deep >120cm ( Soils are alluvium-derived, hence, very deep )
Soil texture: medium (loamy, silty) and fine/heavy (clay) (loamy because of the influence of river alluvium )
Soil fertility is low: Natural fertility is depleted due to continuous cropping
Topsoil organic matter: medium (1-3%) and high (>3%) (Depleted due to long period of intensive use )
Soil drainage/ infiltration is good to medium (Loamy soils with good permeability)
Soil water storage is medium to low (Not much clay and organic matter)
