2.1 技术简介

技术定义:

Lab lab (Lablab purpureus) is planted in a banana garden and trained to creep in the empty spaces for suppressing weeds, stabilizing the soil, fixing atmospheric nitrogen and controlling water runoff.

2.2 技术的详细说明

说明:

The lab lab (Velvet), commonly called bataw or jarabilla, is widespread throughout the tropics. The legume is characterized by creeping and is normally planted as a cover crop in plantations where it is allowed to cover the open spaces. The leguminous crop is normally promoted and planted in banana gardens for it’s immense potential to control weeds and improve and conserve soil fertility. As an inter-crop, lab lab is usually combined with other crops for its high potential of fixing atmospheric nitrogen, controlling soil erosion, providing green manure and retaining soil moisture in support of the other crops. As a mono crop, lab lab is planted on bare land at all slope angles and at any scale to support the soil structure and to control run off. The leguminous plant is also known to be highly nutritious for livestock farming and is used to add protein content value to other pastures when making good quality fodder, silage and hay.

The lablab in the banana garden was established about 1.5 years ago; establishment of lablab legume in the banana garden is defined by the farmer to be simple and cheap depending on the size of land. The activities involved in establishing the cover crop include (1) weeding the garden to provide a competition free environment for the legume to grow. (2) Sowing of the seeds in the garden a few weeks to the start of the wet season (3) training of the germinating lablab at least 0.75 m away from the banana plants. The main maintenance activity involved is training the cover crops from invading the banana plants to avoid competition for nutrients.

The equipment required is only a hoe on small scale farms and maybe a tractor or curt on large scale farms. The expenses involved in the establishment process of lablab legume in a garden of 1.5 acres are mainly dependent on the availability of seed and labor. A kilogram of lablab seed was enough and costs the farmer $1.38, the labor to plough the banana plantation was provided by two of family members for 3 days valued at a total of $5.83. The profitability of the technology by the farmer where seen in the improvement in banana bunch size and the ever green banana plants maintained during the wet and dry season. The farmer before establishing lablab harvested banana bunches of sizes valued at US $ 2.78 – US $ 4.17 but today produces bigger bunches and sells at a price between US $ 4.17 – 5.56 on the local market. The average number of bunches harvested per month is also realized to have improved from 112 to 160 bunches. The weeds in the garden are no longer a big problem to the farmer and the soil moisture can be observed on the ground. The leaves of lablab also decompose as manure in addition to the known leguminous function of nitrogen fixation.
