2.1 技术简介

技术定义:

Dry banana leaves are spread in the soil for growing banana plantation for improving soil fertility and moisture content retention.

2.2 技术的详细说明

说明:

Locally obtained dry banana leaves is a low cost mulching material used by farmers in Northern Uganda to mulch soil in order to grow banana with the aim of improving soil fertility and soil moisture content retention.
The land user identifies a banana plantation usually 0.5 to 2 acres planted with sweet banana, Bogoya, Fear 17 varieties and spread the banana leaves across the banana plantation usually below 40-60 cm to the mother plant using 2-4 people per day, hoes and pangas.
Mulching is preferred because it uses locally available banana leaves within the plantation. It does not require high maintenance costs to pay for labor, digging and transport. Costs would be incurred transporting the mulching material. In addition to conserving moisture in the soils, it reduces water runoff to avoid erosion and improves the soil as the mulch material rots.
However, it is important for the land user to be aware that mulching using banana leaves serve as breeding place for banana weevils and if the land user places the mulch too close to the mother plant it will affect the growth of the young suckers. This therefore means land users who need to use this low cost mulching material need to first work out proper procedures with the extension worker on how to mulch banana plantation before mulching.
To sustain this technology, the land users can integrate cultivating multipurpose tree species (Calliandra and Grivellea) to additionally stabilize the soils and improve soil fertility when the tree mature and leaves litter.
