Embodiment 1

[0068] A water-retaining substrate:

[0069] 1. Fermentation of woody plants

[0070] Woody plant wastes such as branches and sawdust in forestry production are waste and shredded to sawdust with a diameter of no more than 2 to 3 cm. Adjust its water content to 50%-60%, adjust the C / N ratio, add Streptomyces griseus actinomycetes, stir once every 11-17 days, so that the content of humic acid can reach more than 10%.

[0071] 2. Add peat soil, perlite, vermiculite and purple soil in proportion

[0072] According to the quantity of perlite, vermiculite, peat soil, purple soil, and plant fermentation substances, add 5kg, 12kg, 50kg, 10kg, and 70kg. This ratio can enrich the soil capillary, so that the water in the matrix block is relatively retained and can move freely.

[0073] 3. Stir once

[0074] This stirring speed is 40-60 rev / min.

[0075] 4. Add coconut peat, long polyester fiber, and high-strength short polyester fiber in proportion

[0076] According to coconut br...

Embodiment 2

[0086] The difference from Example 1 is that the mass ratios of perlite, vermiculite, peat soil, purple soil, plant fermentation product and water-absorbing resin are different, which are 7kg, 10kg, 60kg, 15kg, 50kg, 0.4kg.

Embodiment 3

[0088] The difference from Example 1 is that the mass ratios of perlite, vermiculite, peat soil, purple soil, plant fermentation product and water-absorbing resin are different, which are 6kg, 11kg, 55kg, 13kg, 60kg, and 0.35kg.

Abstract

The invention provides a water-retaining matrix, a preparation method and an application thereof. The water-retaining matrix contains the following components: soil, water-absorbing resin, plant fermentation products, perlite, vermiculite and fiber carriers with the weight ratio of 60-75:0.3-0.4:50-70:5-7:10-12; and the fiber carriers are coco coir and / or polyester fiber. The water-retaining matrix provided by the invention has the characteristics of high water-absorption rate, long water-retaining time, rapidness in curing, rich nutrition, improvement of cold resistance of plants and the like.

Description

technical field [0001] The invention relates to the field of planting, in particular to a water-retaining substrate and its preparation method and application. Background technique [0002] Urban three-dimensional greening is one of the important forms of urban greening, and it is an important and effective way to improve the urban ecological environment and enrich the urban greening landscape. The development of three-dimensional greening can enrich the spatial structure level of urban landscaping and the artistic effect of urban three-dimensional landscape, help to further increase the amount of urban greenery, reduce the heat island effect, absorb dust, reduce noise and harmful gases, and create and improve the urban ecological environment; It can keep heat and insulate, save energy, and can also retain rainwater to relieve the pressure of urban water and drainage. [0003] Many cities around the world attach great importance to three-dimensional greening. In Japan, the...
