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 disclosure belongs to the technical field of ecological environmental protection, resource development and utilization and new materials, and particularly relates to a method and device for rapidly forming artificial clay and artificial organic ecological mud. The method comprises the following steps: raw material and water storage preparation; preparing nutrient aqueous solution; preparing mineral muddy water; preparing flocculent mineral solution; and reacting and dehydrating to form artificial clay or artificial organic ecological mud. The device comprises a grinding mill, a feeding system, a silo, a belt conveyor, an agitator, a dehydration system and a reservoir. In accordance with the present disclosure, the formation period of natural clay is greatly shortened by artificial means, making the clay become a renewable resource.

A modular hydroponic tower array fixture system for the growth of organisms such as plants and fungi on arrays of hydroponic towers, allowing for the insertion and removal of individual towers from the array, is provided. Methods for the production of organisms such as plants and fungi using a modular hydroponic tower array fixture system are also provided herein.

A method for processing raw coconut coir pith into fine particles and the use of such fine particles directly or in formulated form in agricultural, industrial and commercial applications.

Kits for seed pre-germination are included. The kit includes a storage vessel and a seeding composition. The seeding composition includes plant seeds, a porous granular material, and a polymer-coated fertilizer. Methods for preparing seeds for germination are also included. The method includes combining the seeding composition with water in the storage vessel and sealing the storage vessel, such that little to no aeration is permitted during subsequent storage of the same.

Various disclosed examples relate to a growth medium including expanded polymer particulates, as well as a growth environment including the growth medium, a container housing a nutrient solution and a plant such that roots of the plant are received in the growth medium. Associated methods of preparing the growth medium are also contemplated, including sterilization of the growth medium and preparation of the growth medium with a growth promoting agent.

A composite, time-delayed, polymer-coated, granulated material for maintaining hydration in plants is formulated to delay acceptance of water in order to operate in drilling, plugging, and disking equipment used for aeration, soil amendment, or both. Whether potted or outdoors, whether relying on a third-material binder or a small, hydrated portion of the polymer itself as a binder, the material may be injected or otherwise placed below the surface of soils. Water is eventually absorbed sufficiently to expose the bulk of the hydrating particles attached to each granule. Addition of the granulated material as a soil amendment resists dehydration normally occurring in plants between waterings, yet its initial delay in hydrating supports water-jet injection and soil integration by resisting premature expansion from hydration.
