Rice mechanical transplanting connection-pot rice seedling raising disk

Abstract

An integrated rice seedling raising disk for mechanical rice transplanting relates to an environment-friendly rice seedling disk for mechanical rice seedling raising and planting, and can realize mechanical transplanting of disk-raised rice seedlings. The rice seedling disk is made by compounding a plastic disc with non-woven fabrics. The integrated rice seedling raising disk is made by pressing 12-15g / m<2> ultrathin non-woven fabrics or felt at the upper layer and the plastic disk at the lower layer together; and the two layers are attached by weak glue. The plastic disk at the lower layer consists of a disk body and a cone body, the disk body takes a rectangle shape; the top of the cone body and the disk body are connected into an integral structure; the cone body is longitudinally and horizontally distributed on the disk body at the same spacing; and the plastic disk at the lower layer can be repeatedly used to save cost. The upper layer of the disk can be transplanted into a rice field along with rice seedlings, and can protect the roots of the rice seedlings and can be degraded as well; therefore, the integrated rice seedling disk is an environment-friendly product, and has the advantages of simple manufacture, low cost, protection of the ecological environment.

Description

technical field [0001] The invention relates to an environment-friendly seedling tray for rice mechanical seedling raising and planting, which is mainly suitable for pot seedling raising and mechanical planting. Background technique [0002] Mechanical transplanting is the leading direction of rice cultivation in China in the future. The currently used machine-transplanted plate-raised seedlings are connected as a whole by the felt-like root layers formed by the intertwining of the roots of the seedlings. In order not to disperse the discs, grow strong seedlings and reduce seedling leakage, the sowing density is more than twice that of ordinary hand-transplanted seedlings. Due to the high density, the root system is intertwined and tangled together. When the seedlings are torn by the seedling needles, the roots are broken and the seedlings are seriously damaged. The greening period is generally more than one week. The damage to the root system affects the occurrence of low t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to aim at the technical problems and shortcomings that the seedlings raised by conventional plastic seedling trays cannot be used for mechanical transplanting, and to design and provide a rice conjoined bowl seedling tray, which is made of plastic bowl trays and non-woven fabrics. When raising seedlings, it is carried out according to the conventional method of raising seedlings in pots, so as to achieve the purpose of low-cost potting and planting of rice seedlings
