The present invention relates to a rice seedling substrate and a preparation method thereof, which is of the technical field of rice planting. The rice seedling substrate according to the invention was prepared from the raw materials includes the following by volume: 40-60% of dredging sediment, 30-50% of vegetable straw, and 10-30% of hickory shell. The rice seedling substrate according to the invention can not only turn waste into treasure to improve the recycling rate of sediment and agricultural and forestry waste resources, but also save the limited cultivated soils, reduce the production cost of rice seedling substrate, and promote the healthy and sustainable development of rice planting. Therefore, The inventive substrate has significant benefits in terms of economics, sociology and ecology.

Provided are systems and methods for vertical farming that reduce the deployment cost, operational costs of human labor, and overall use of energy intensive processes, such as lighting, heating and cooling, and ventilation, while increasing crop quality and yield. This reduction is achieved through a hybrid system that alternates natural light, temperature, and ventilation sources with system-controlled lighting, temperature, and ventilation means. The system includes a germination module that allows seeds to germinal on a horizontal substrate, a growth module that provides optimal growth conditions to the germinated seed on the substrate in a vertical position, and a dosing module that controls the micronutrient mixture supplied to the growing plants.

A method for reducing salinity stress symptoms in a seed plant, comprising the step of adding carbon-based nanomaterials into a salinity growth medium in which the seed plant is cultivated, the salinity growth medium is in a salinity condition which causes the seed plant cultivated in the growth medium demonstrates the salinity stress symptom.

The present invention concerns a process for preparing a composite of porous material/compound/hybrid organic-inorganic material having a 2:1 lamellar structure, said hybrid material having the following general formula I:

Na.sub.x[(Mg.sub.3)(Al.sub.x(RSi).sub.4-x)O.sub.8+x(OH).sub.2](I)

wherein
x is a number such that 0x<1.2 and
R represents a C.sub.1-C.sub.30 alkyl group, an aryl group, a (C.sub.1-C.sub.30 alkyl)aryl group or an O(C.sub.1-C.sub.30 alkyl) group, it being possible for the alkyl group to be substituted with a group chosen from a phenyl, vinyl, aminopropyl or mercaptopropyl group,
and said compound being chosen from the group constituted of at least one active substance and at least one microorganism and mixtures thereof the process comprising:
a) the step of sol-gel synthesis of the hybrid organic-inorganic material having a 2:1 lamellar structure in the presence of the compound and of the porous material saturated with the compound;
b) the recovery of the composite.

It also concerns a composite obtainable by means of this process, a composition comprising it and its use in particular for the fertilization of plants.
