Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely through the following examples. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0017] In the present invention, the lightweight water-retaining matrix formula of the roof garden is mainly composed of leaf humus (40%-60%), sawdust (20%-40%), urea (1%-5%), wheat Bran (1%-5%), vermicompost (10%-20%), sepiolite (5%-10%).

[0018] Among them, the core matrix is ​​leaf humus and sawdust fermented soil.

[0019] see figure 1 , the preparation method of leaf humus among the present invention is: collect wastes such as fallen leaves, rotten vegetable leaves, banana peels, orange peels, prepare an airtight box, waste and garden soil are filled in the box with the ratio of 2:1, Mix a small amount of carbofuran to prevent insects. When composting, put a layer of waste first, then a layer of garden soil, re...

Abstract

The invention discloses a lightweight moisture holding matrix formula of a roof garden, wherein the lightweight moisture holding matrix formula is prepared by selecting lightweight and breathable raw materials with water retention and fertilizer retention, and mixing raw materials according to different ratios. The leaf mould is piled with wastes such as fallen leaves and fruit peels and garden soil at the ratio of 2: 1. The lightweight moisture holding matrix formula has the advantages that the formula material is lightweight and water-holding, thus the bearing pressure of the roof is lightened and the watering frequency is reduced; the nutrition component is high and has balance ratio, so it is good for plant growth; besides, the formula can rapidly absorb water and then slowly release, thus the formula has extremely strong moisture holding and fertilizer holding functions; the matrix is in the shape of particle and has good permeability; the cost is low; the raw materials are simple and easy to obtain; nature wastes are fully used, thus the formula is easy to promote and popularize.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a lightweight water-retaining substrate formula for roof gardens. Background technique [0002] The development of modern architecture requires the coordination between architecture and the natural environment. It is a new concept of modern architecture to introduce green space into the architectural space. In this context, the roof garden has received great attention. Roof gardens can increase the urban greening rate and reduce the "heat island effect", which is the development trend of urban architecture. However, due to the high temperature of the roof in summer, the strong transpiration of plants, and the difficulty of water supply on the roof, the development of roof gardens is limited by conditions such as load bearing, drainage, and waterproofing. Therefore, fertilizer and water retention and light breathability are the key points of the green substrate of the roof g...
