2.1 技术简介

技术定义:

Laying grass (Poaceae) on perennial cropped land to reduce weeds, retain soil moisture and improve soil fertility.

2.2 技术的详细说明

说明:

Mulching using grass (Poaceae) on banana cropped land is a common practice usually promoted by farmers in Northern Uganda with the aim of increasing soil fertility, reducing the likelihood of weed problems growing around perennial plants, increase production and household income.
The farmer identifies a field planted with banana approximately 2 acres of land measuring at least 80 metres wide and 240 metres long located on a gentle sloping area of (3-5%), and mulch using grass which is grown in the planted banana garden. The mulch grass used comes from the same field carried away from other fields.
Using a panga the farmer uses 5 people paid on daily basis to cut and carry the grass and lay the grass at a distance of not more than 20- 40 cm to enable the suckers grow and to allow manure too close to the plant after grass decomposition and helps weeds control,
With this technology, the farmer uses locally obtained grass mulch which is easily comes from the banana field that would considered a waste. Secondly the associated costs are only related to transport and labour are low both in the short and long term since the mulch used is obtained from the same field. Costs for labour and transport are incurred only when the mulch material is carried from other areas. Some others costs are for weeding which would be borne by the farmer.
However, the farmer need to know that organic mulches usually need to be applied in a loose or partially-rotted state or the first stages of decomposition, otherwise they can lead to nitrogen being taken from the soil, or anaerobic decomposition which can lead to ‘sour mulch’ which turns acidic and damages the plants it is supposed to be protecting. This advice can best be extended to the farmer by extension workers and expert farmers who the farmer needs to be if close contact during implementation of this technology.

注释:

Mulching using grass reduced workload in the short run associated with less costs in the long run .The labour that would be used for weeding and its associated costs reduce since no weeding is required when the banana is mulched. Mulching reduces weeds and increases water moist which increases banana production due to decomposed mulched material (grass).

Appropriate for farmers with low income.
Is scalable, requires low labour and input costs.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
Harbours insects which attack young suckers.	Apply pesticides.
The technology is easily affected by roaming animals searching for pasture during the dry season when there is normally shortage of pasture.	Put in place byelws on controlled grazing Integrate fertilizer trees (calliandra and Grivellea) in the practice as an alternative.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
Mulching can increase the risk of diseases especially if the grasses are obtained from outside the garden.	First use the grass in the same field.
Mulching alone may not be a solution to increase production. The farmer needs also to mange well the banana by cutting banana leaves which can also act as mulching material.	Knowledge and skills be provided by the extension agent.
