SEEDLING-RAISING TRAY MADE FROM STRAW FOR SEEDLING-RAISING OF RICE, AND PREPARATION METHOD THEREOF

摘要

A seedling-raising tray made from straw for seedling-raising of rice, and a preparation method thereof belong to the field of agricultural production and manufacturing technologies. The seedling-raising tray material is composed of straw powder, water-soluble biological emulsion, micronutrient fertilizer nutrition medium soil, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, disinfectant and acidity-modulating agent with different weight by matching; the preparation is completed by the technical processes of straw crashing, mixed stirring, hot-press modeling and drying sizing, and the like; the seedling-raising tray can be transplanted in the paddy field with rice seedling and alms bowl blocks, and can also be degraded in the paddy field, and the rice seedling does not have seedling-postponing stage after the transplantation. The present invention is characterized by being rich in nutrition, and beneficial to the growth of the crops, fertilizing soil productivity, and reducing the production and manufacturing costs.
