Raising seedling mat and rice multi-stage lathe raising method using the same {THE RAISING SEEDLING MAT AND THE RICE RAISING SEEDLING METHOD ON A MULTISTAGE SHELF BY USING THEREOF}

The present invention relates to an upper and lower mats for seedlings and a rice multistage lathe seedling method using the same.

Known techniques related to conventional rice seedling mats include a method of manufacturing seedling mats for rice transplanting machines, characterized in that the drying and sterilization process is performed in Korean Patent Application No. 1987-0014072 (manufacturing method of artificial seedling mats for rice transplanting machines). About, a method of manufacturing artificial mats for seedling boxes by mixing rice straw and organic soil waste paper kraft paper, which have been boiled in Korean patent application 1992-0016229 (manufacturing method and composition thereof), Korean patent application 1999-0052005 ( Confetti top for rice seedlings), confetti top plate made lightly using waste paper, rice straw, flour and the like.

However, the conventional mat for raising seedlings is composed of one, so that it takes a lot of time and effort by planting on the mat and covering it with a separate soil for soil, and there is a drawback that the shoots grow irregularly according to the height of the soil soil covered. .

In the lower growth mat, clay minerals such as vermiculite, rice straw, waste paper and the like were used as raw materials, so that the bonding strength and the water holding capacity were poor.

In addition, in the conventional rice seedling method, by placing the seedling box on the paddy field and raising the seedling, since the roots grow out of the seedling box and penetrate into the paddy field, it is necessary to cut the roots in Yiang after the seedling. there was.

The present invention has been completed through many years of research experiments to solve the above-mentioned drawbacks.

An object of the present invention is to reduce the work time and effort at the time of seedling by providing two mats for the upper, lower seedlings.

In addition, the upper mat is suitable for the composition ratio of the raw material and the thickness and weight of the finished mat to ensure that the shoots grow evenly.

Still another object of the present invention is to increase the bonding strength and water-retaining power by using a certain ratio of vermiculite, coco peat or peat moss as raw materials when manufacturing the mat for lower growth to help the growth of rice.

Still another object of the present invention is to reduce the time and effort required for cutting the roots during the transplanting operation and increase the space utilization by seedling the multi-stage shelf using the upper and lower mats manufactured in the present invention.
