发明名称 Plant protection system
摘要 In the transplanting of seedlings, such as, tomato plants, soil prepared to receive the plant seedlings has a mulch layer of sheet material spread over the area in which the plants are to be grown and spaced holes are formed through the sheet material and into the soil with a seedling then introduced into each hole. Thereafter, a generally tubular protector is inserted through the sheet material into the soil surrounding each seedling so that the peripheral exterior of each protector is closely surrounded by the sheet material at the perimeter of each hole with an upper portion of each protector extending above the sheet material to enclose the stem portion of the seedling and a lower portion of each protector embedded in the soil beneath the sheet material to surround the root formation of the seedling. Each protector may have a downwardly tapering form where it encloses the seedling.
