Soilless seedling raising tray and its processing method

Abstract

The invention relates to a soilless rice nursery tray, which relates to a rice nursery product utilizing straws to replace rice seedling soil, and is prepared by the following materials in weight ratio: 80-90 percent of smashed and fermented straws and 10-20 percent of auxiliary materials which are molded through a vacuum suction mold, wherein the auxiliary materials are acid organic matters or acid modulation materials and / or fungicide of minerals. A processing method comprises the following steps of (1) selecting the plant straws as main materials, and smashing and mixing with fertilizer to ferment to obtain fine powder; (2) mixing with the auxiliary materials, and adding water to form a pulpous state; (3) adopting the vacuum suction mold to mold; (4) stoving; (5) reshaping. The product has no need to add adhesion agent during the molding process, and has the advantages of loosening and ventilation, capability of being benefit to plant root system growth, and suitability for rice seedling. A vacuum absorption process is adopted to process, so that the tray is naturally resolved into loosened granulates without being hardened after being watered, and the plant growth cannot be affected. The production process and processing equipment are simplified, and the production cost and the equipment investment are reduced.

Description

technical field [0001] The invention relates to a rice seedling-raising product that uses straw instead of rice seedling-raising soil, and specifically relates to a rice seedling-raising sheet made of organic materials such as straw as a main material and auxiliary materials such as acid-adjusting materials and bacterial agents, and a processing method thereof. Background technique [0002] my country is a big agricultural country with a large amount of straw. Most of the straw is not used, which will cause waste of resources and environmental pollution in the process of burning and discarding. So how to use straw and other organic wastes to replace soil to solve the current problems of straw waste and difficulty in obtaining soil for rice seedlings? At present, conventional nutrient soil seedlings need to take soil, transport soil, sieve soil, mix soil, and also need to pack, transport and arrange. Based on the 55 million mu of paddy fields in Heilongjiang Province, it is...

Problems solved by technology

However, straw molding is a technical problem currently faced. The usual solution is to use thermoforming technology, adding adhesives to the raw materials, which makes the product easy to harden when used, and the product becomes a block, which is not easy to further decompose, making the product breathable. The sex is greatly reduced, which is not conducive to seed development and directly affects the growth of rice seedlings.
