The present invention belongs to the technical field of landscape garden engineering, and specifically discloses a salt-isolated rain garden structure. The salt-isolated rain garden structure includes a depression surrounded by side slopes, where a 10 cm thick drainage layer, a 10-30 cm thick filler layer, a 5 cm thick transition layer, a 20-30 cm thick planting layer, a 0.2-0.5 cm thick mulch layer and a 15-20 cm thick ponding layer are stacked in order from the bottom of the depression to up; a salt barrier is disposed between the planting layer and the transition layer and/or between the drainage layer and a saline layer; a vertical overflow pipe and a horizontal drainage pipe are disposed at the bottom of the depression; the overflow pipe and drainage pipe are connected; the salt barrier is filled with river sand, zeolite or ceramsite and is 10-20 cm in thickness.

The present invention concerns a Portland cement-free porous rigid mineral substrate made of alkali-activated pozzolans, a method for preparing the same, and use of said substrate to optimize plant germination and growth.

The element is intended to be placed in a receptacle for the cultivation of at least one plant, and includes:

a substantially solid body including a substrate adapted to enable said plant to develop;

at least one seed of said plant disposed on the body in at least one seed receiving area;

a layer for holding the seed(s) in said receiving area, comprising a dried mineral powder.

The holding layer results from drying a deposition of a holding composition including a mineral powder suspended in water.

The presently claimed invention is related to a method for vegetative propagation of poplar trees (Populus sp.), from prepared leaf cuttings, wherein the method comprises the steps of: a) providing cuts of leaf cuttings from a donor tree, b) immersing the prepared leaf cutting into a combination of growth regulators, c) planting the prepared leaf cutting into a solid substrate of organic and/or inorganic origin, d) inducing sprouting and rooting of the prepared leaf cutting, by means of controlled ambient temperature, humidity and illumination, wherein steps a) through d) always occur outside an in vitro environment; and embodiments thereof.

A method for hydroponic cultivation of crops by using mycorrhizal fungi and their partner bacteria includes growing a partner plant between rows of the crops, and inoculating a mycorrhizal fungal strain and a partner bacterial strain to infect the partner plant or the crop with the mycorrhizal fungal strain, wherein the partner bacterial strain is compatible and coexists with the mycorrhizal fungal strain, and the partner plant facilitates growth of the mycorrhizal fungal strain and the partner bacterial strain.

A culture support substrate comprising: a first part, making up the backbone of the substrate and representing more than 70% of the total volume of the substrate, composed of particles P.sub.>100 m with particle size greater than 100 m, the particles as a whole consisting of hard particles P.sub.H>100 and/or of resilient particles P.sub.R>100, wherein the resilient particles make up a proportion by volume PV of between 0% and 100% by volume of this first part; a second part of corpuscular components P.sub.<100 with a particle size of less than 100 m, and making up from 0 to 450 g/l of the substrate; a third part, making up from 0 to 200 g/l of the substrate, composed of fine fibers between 3 mm and 100 mm in length and between 5 m and 35 m in diameter; and a fourth part, making up from 0 to 200 g/l of the substrate.
