Ecological seedling tray and manufacturing method thereof

Abstract

The invention provides an ecological seedling tray and a manufacturing method thereof. The ecological seedling tray comprises waste papers, expanded rice husks, and at least one selected from corn stalks and rice straws obtained by cutting, crushing, decomposing and fermenting operations. With respect to 100 wt% of the total weight of the waste papers and the expanded rice husks, the waste papers account for 20-35 wt%, the expanded rice husks account for 65-80 wt%, and the at least one selected from the corn stalks and the rice straws account for 25-35 wt%. By mixing them, shaping them according to the prescribed specification and drying them, the ecological seedling tray of the invention is obtained, which provides rich celluloses and nutrients and achieves improved water absorbability and permeability, so that seedlings take root and grow well. The ecological seedling tray of the invention allows easy control of the nutrients or water and eliminates barrier factors of successive plantation, thereby enhancing yield safety and mass production.

Description

technical field [0001] The present invention relates to an ecological seedling raising tray and a manufacturing method thereof, in particular to forming an environment-friendly raw material suitable for raising seedlings by properly mixing at least one of corn stalks and rice straw, rice husks, waste paper, etc. Molding is performed to provide an ecological seedling tray for promoting the growth of seedlings of rice or other various crops, and a manufacturing method thereof. Background technique [0002] In general, seedling cultivation methods are developed in various forms such as dry seedbeds, non-woven fabrics, and plastic greenhouses. Recently, due to the aging of rural areas, the lack of young labor force, the serious shortage of surface nutrient soil sources, the country's promotion of industrialized seedling cultivation and large-scale mechanized applications, etc., especially in the busy season of seedling cultivation and planting, the price and usage of seedbed soi...

AI Technical Summary

Problems solved by technology

Seedling trays made by drying in a high-temperature environment above 120-210°C have problems such as difficulty in obtaining uniform commerciality due to uneven shape of the seedling tray, and difficulty in uniform management after being put into the seedling tray.

In addition, due to the lignification and deformation of the over-dry seedling tray, it absorbs water slowly; there are also difficulties caused by parallax when it is used to automatic mechanical seeding

Therefore, when the seeds are sown in a state where the seedling tray has fully absorbed water, there is also a problem that the root of the seedlings may be peeled off during germination.
