A cultivation method for drip irrigation of cotton fields in saline-alkali soil is provided, belonging to the field of agricultural planting technologies. It mainly includes performing land preparation; setting a planting mode; laying tubes; performing a high frequency drip irrigation; fertilizing with water; performing intertillage; performing chemical control; and performing green prevention and control.

The present invention provides compositions, kits and methods for growing more vigorous, larger, and healthier plants, including from clone cuttings.

The present invention relates to a system that allows the manufacturing and/or continuous automated production of at least one film, cover, mantle and/or mesh made of polyethylene, plastic material, among other materials, which comprises in an integrated manner at least one fluid distribution line, so that the manufactured product allows to deploy both component simultaneously, without the need to be deployed on a field separately, which comprises at least one device for continuous and automatic feeding of the film, layer, mat and/or cover made of polyethylene and/or plastic (2), at least one device for continuous and automatic feeding of at least one element for delivery, distribution and/or removal of fluid (3), preferably at least one irrigation line, at least one automatic and continuous feeding device of at least one sleeve (4), at least one thermofusion device (5), and at least one control system.

The invention pertains to an agro- or geotextile (1), comprising: i) a carrier (2); and ii) an electric network (3) of one or more lighting units (4, 18), whereby said electric network (3) of one or more lighting units (4, 18) is provided on a surface of said carrier (2). The invention further pertains to a method for producing an agro- or geotextile (1) and to a use of an agro- or geotextile (1) according to the current invention.

The present invention provides an agricultural film formulation, which comprises about 40 wt % to about 70 wt % inorganic mineral powder, about 15 wt % to about 30 wt % high-density polyethylene, about 8 wt % to about 20 wt % low-density polyethylene, about 5 wt % to about 10 wt % biodegradable plastic, and an optional auxiliary agent, based on total weight of the formulation. The present invention also provides an agricultural mulch film made from the agricultural film formulation and a preparation method thereof.

A solar-reactive agricultural mulch film including a sheet of heat-shrink material having one or more layers and uniform thickness, formed by a mechanical process. The process includes elongating the sheet, in a longitudinal direction, evenly across a width of the sheet, while the sheet is at a stretching temperature to pre-strain the sheet evenly across the width, and yields the solar-reactive agricultural mulch film having the uniform thickness throughout and being configured to, in operation, shrink when an exposure temperature of the material is elevated, by exposure to solar energy, to a shrinking temperature. The process may include elevating the sheet to an above-ambient stretching temperature for the elongating, or elongating the sheet at an ambient temperature.

A process for manufacturing a bio-polymer mulch film is provided. The process comprises coating at least parts of a surface of a bio-polymer film with a functional material. The functional material may comprise a light absorber material, a light reflector material and/or a pigment.

A multilayer film comprising two layers, A and B, having a A/B/A arrangement, wherein layers A and B differ from each other. Layer A comprises an aliphatic and/or aliphatic-aromatic biodegradable polyester or a polyvinyl alcohol or copolymers thereof and does not contain starch. Layer B comprises 30-95% by weight of at least an aliphatic-aromatic polyester (AAPE), 0.1-50% by weight of at least a polymer of natural origin, and 1-40% by weight of at least a polyhydroxyalkanoate (PHA). The multilayer biodegradable film which is particularly suitable for the manufacture of packaging and has appreciable optical transparency properties in addition to high level mechanical properties.

The present invention provides compositions, kits and methods for growing more vigorous, larger and healthier plants, including from clone cuttings.
