2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The plantation of mulberry plants which are alloewd to grow for the production of nutrient leaves for silkworm mulberry cultivation for silkworm.

2.2 Detailed description of the Technology

Description:

After one year of plantation of mulberry plants. They are ready to be eaten by silkworm. Firstly,silkworm eggs must be stay between 25 to 30 degree celcius. In tray or petric disc. In this area silkworm are brought from khopasi silkworm industry. The larvae must be transfer to clean tray with fresh food. A time came in larveal stag when larvae eats huge amount of mulberry and grow more than 5 cm long . After enough eating, larvae raise their heads as it shows sign for cocoon formation. Then, the worm is kept in another circular bamboo which will make cocoon more uniform in shape and easier to collect silkworm by contracting secrets from from an opening under its mouth a steady stream of liquid silk coated with sericine which dardens on exposure. It takes about twenty-five days to form cocoon.

Purpose of the Technology: The main purpose of planting mulberry plant is for producing silkworm to increases economic condition of farmer.

Establishment / maintenance activities and inputs: For over two years people have been implementing these technology.They took traning from the khopasi silkworm institution.They have get external inputs.While geting training,maintance has been carried out when the plants are not grown enough.While producing the silkworm (larva to coocon) maintaince is carried out as keeping them in clean environment without reaching another species around them.

Natural / human environment: The natural environment is tropical with temperature ranging from 20 to 25°C .The population density is sparse with the community relying heavily on agricultur
