Problems solved by technology

[0015] While rapid degradation is required, the application of thicker films does present some practical problems due to the slow decomposition of the seeds after germination, and in addition, certain difficulties have been demonstrated in efficiently machining the films; finally, higher thickness plastics applications are not always economically feasible
[0016] Using existing film extrusion machines, it is practically impossible to extrude films with a thickness of less than about 8 microns

Embodiment Construction

[0047] Referring to Figure 1 which illustrates an actual scheme, the film is introduced into the stretching machine 10, which includes a low-speed stretching roller 11 mechanically connected to the high-speed stretching roller 12. As the film is removed from the film roller 15, the high-speed stretching roller In contact with the film, the film is stretched in the gap 16 between the film roll and the high-speed stretching roll 12. The stretching action will significantly increase the area of ​​the membrane suitable for covering the soil. The film can be stretched along the length direction or the width direction or the length direction and the width direction of the film. The elongation can be as high as 300% stretch. The film can then be distributed directly onto the tilled soil 17 via exit rollers 13 and 14.

[0048] The stretching of the film can be achieved by a number of different methods that do not deviate from the inventive concept. For example, direct brake film rolls or ...

Abstract

Plastics film for covering cropping soil or frame structures, containing or destined to contain seeds, to cover seeded soil or soil destined to be seeded, is stretched beyond its yield point to achieve reduced thickness whereby the web quickly deteriorates to allow passage of germinated seedlings. Also claimed are (i) a film as above which is of non-ultraviolet resistant, photo or biologically degradable material, and the stretching reduces the thickness to 10 ~mm; (ii) a film as above which is a dual ply film which may have air trapped between the plies; and (iii) a film as above which is subjected to further localised stretching in a pattern or lines to encourage crop egress in the pattern or along the lines.

Description

Technical field [0001] The present invention relates to the improvement of plant propagation technology, in particular to a method for promoting the germination of plant seeds in cold climates. Background technique [0002] In mild climate zones, especially in Europe, the Commonwealth, North America, southern Australia and New Zealand, the germination of seeds is routinely delayed until the soil temperature rises above the minimum temperature determined by the nature of the seeds and after the possibility of frost is reduced. In addition, it is hoped to improve the water retention in the soil, especially in the dry climates that occur in regions such as Africa, Australia, and the United States. [0003] The present invention relates to the propagation of various plant seeds. However, it will be specifically described with reference to the growth of corn crops, which represent most of the summer temperate crops. [0004] Corn has a long growth period of about 5 months before the c...
