Roof greening nutrition bag and manufacturing method

Abstract

The invention provides a roof greening nutrition bag. A mixed filler formed by mixing clay, slow release fertilizer, organic substances and aggregate is filled in the inner layer of a closed bag body, and the outer layer of the bag body is made of non-woven fabric. The manufacturing method comprises the processes of manufacturing the bag body, mixing the filling materials with stirring, filling the mixed filler, and sealing the bag mouth. The miniaturized nutrition bag can be used as special aggregate; the nutrition bag, brick rubbles, ceramic grains, pumice stones, organic substances and the like are prepared into a planting layer base material according to a certain proportion so as to improve the drought resistance of the planting layer and keep the endurance of the nutrition; the nutrition bag also can be used as a special seedling pot, the bag body is pricked, plant seeds are sown on the nutrition bag or seedlings are planted on the nutrition bag, and the nutrition bag is blended with a roof greening base material or planted on the base material; and the nutrition bag also can be spread under the granular roof greening planting layer to serve as a roof greening water-holding nutrition layer.

Description

technical field

[0001] The invention relates to a bagged nutrient material for planting, in particular to a nutrient bag used for roof greening and a manufacturing method thereof. Background technique

[0002] The structure of a green roof is generally a structural layer, a waterproof layer, a drainage layer, a filter layer, a planting layer and vegetation on it. The disclosed invention and other technical data provide the technical schemes of several types of roof greening substrates or planting layers: a, take the soilless light mineral material as the main component, and add fertilizers, water-retaining agents, etc. (such as the technical scheme of the invention "Inorganic cultivation substrate for greening", application number: 200410072723.9); b, the technical scheme of using farmland or farmland topsoil as the main component, adding fertilizers, etc. 96100525.4); c, using organic matter as the main component, adding long-acting fertilizers, water-retaining agents, etc...
