Use of a fabric in a technique of preculture for the revegetation of substrates and various supports and assembly of preculture obtained.

摘要

The absorbent jute canvas, which can be woven or not, is used for the pre-cultivation support of vegetation in substrata and various supports. It is used for the pre-cultivation of fragments of stonecrop or perennial plants. The canvas has a water absorption rate greater than or equal to 10%. Each thread of the canvas is constituted by several elements each having a diameter less than 30 mu m. The canvas mesh is between 1 and 5 mm and its weight is between 100 and 500 g/m2. A first type of pre-cultivation support is obtained with a jute canvas with spacing between thread wefts and warps of 3.3 mm placed directly on a plastics film . A large quantity of stonecrop fragments per square metre and a layer of classic nutrition elements (N,P,K,Mg) is placed above. In a second type of support, humus, constituted from brown peat and pine wood fibres, is placed under the jute canvas to a thickness of 7 mm.
