摘要:
An agricultural system includes an irrigation system, a mulch system including mulch material, and indicia disposed on the mulch material for indicating locations on the mulch material. The indicia include burial indicia, conduit warning indicia and plant spacing indicia. The planting spacing indicia are disposed in a triangular grid on the mulch system. The mulch material includes a hole for planting, a hole for a stake to pass there through, and a hole for a row cover support to pass there through. The irrigation system includes a drip irrigation conduit and a further conduit for transporting water to a further irrigation system. The irrigation system includes a fitting and a manifold for transporting water to the further conduit. At least a portion of the irrigation system is bonded to the mulch system, and at least a portion is enclosed and maintained in the vicinity of the mulch system by a sleeve.

摘要:
The present invention is related to an innovative irrigation system using plastic film applied to cultivated furrows to capture rain water or water sprayed by irrigation systems that simulate rain; characterized by a plastic film installed in the valleys between adjacent furrows where an amount of dirt is first moved from the sides of the adjacent furrows, forming a mound to support the film, which forms a dome or convex channel to capture rain water or sprinkler water and guide it to the upper mound of adjacent furrows, directly to the root system of cultivated plants; said film is installed manually or mechanically, and the side edges of said plastic film are buried or pressed into the sides of adjacent furrows, with these edges remaining buried, to be secured in the ground; said plastic film covers the entire valleys and part of the sides of the furrow, with the plants located on the mound of the furrow.
摘要:
A mulch barrier film having, for example, a methyl bromide permeability of less than about 15 g/m2-hr and machine direction Elmendorf tear strength of at least about 75 gf. The mulch barrier film is an extruded, cast, and preferably embossed, multilayer film having at least one polyolefin layer and at least one polyamide layer. The combination of the film structure and the casting process achieves a barrier film that has low permeability to volatile soil treatment chemicals, such as methyl bromide, and superior tear strength properties.
