摘要 |
In a process for the protection of cultivated plants, a pigmented, flexible, synthetic plastics film which is partially opaque to solar radiation is applied to the soil on which the plants are cultivated. In an example, a polyethylene film (40 microns thick) pigmented to a smoke-grey colour by incorporation of carbon is placed over soil in which young melon plants are growing. Development of the plants is improved. |
