Problems solved by technology

[0002] Substrate is a common material for soilless cultivation. It usually uses compost materials such as peat, coconut peat, perlite, and litter. According to the growth characteristics of different plants and the different use environments of the substrate, special-purpose substrates suitable for specific conditions are prepared. Cultivation nutrient substrate is easy to manufacture, low in cost, and adjustable in nutrients. It is commonly used in gardening, urban greening and agricultural production. However, the existing substrates are usually powder or granular materials, which require large-scale application before planting, or require users to manufacture and plant themselves. Substrate blocks, on the one hand, are inconvenient to use, on the other hand, the growth needs of the plants in different growth stages are often different

preparation example Construction

[0036] A preparation method for a composite biological matrix for roof greening, the preparation of the composite biological matrix may further comprise the steps:

[0037] Step 1. Lay the top layer, fiber layer I, water storage layer I, fiber layer II, water storage layer II, bottom layer and waterproof layer sequentially from top to bottom to obtain a layered structure;

[0038] Wherein, the fiber layer I and the fiber layer II are loose mats mixed and pressed by high-temperature sterilization of crop straw fibers and coconut shells; the aquifer I and II are peat soil after high-temperature sterilization , the compressed layer after mixing sphagnum moss and granules;

[0039] Step 2: Open planting holes evenly at a certain interval on the layered structure, and the planting holes sequentially penetrate the top layer, fiber layer I, water storage layer I, and fiber layer II, and the bottom of which is located in the water storage layer II;

[0040] Step 3: Insulate matrix I,...

Abstract

The invention relates to a compound biological substrate for greening roof and a preparation method thereof. The compound biological substrate is combined with separable laminated structure and blocky structure, wherein the laminated structure comprises a top layer, a fiber layer I, a water storage layer I, a fiber layer II, a water storage layer II, a bottom layer and a waterproof layer in turn from top to bottom. According to the compound biological substrate for greening roof and the preparation method thereof provided by the invention, the compound biological substrate has a certain structure according to the difference in the rooting depth of the plant in different growth stages, so that the purposes of preserving moisture and fertility and boosting the continuous healthy growth of the plant can be achieved. Meanwhile, the compound biological substrate and the preparation method thereof can prolong the existence time of the plant layer, can save the greening cost, can meet the requirement for standard and large-scale production and can effectively boost the popularization and application of the roof greening in China.
