Problems solved by technology

Plastic trays cannot be directly transplanted by machine, and cannot be naturally degraded. Manual throwing or secondary transplanting is required. The requirements are very high, and the price itself is expensive, so it is difficult to popularize and implement; the pulp tray is more commonly used now, and its cost is low, but the pulp tray prepared in the prior art has low hardness and strength, and it has rotted in the process of raising seedlings, so it cannot be implemented Machine plug

Abstract

The invention provides a degradable straw seedling tray and a production method thereof. The degradable straw seedling tray comprises, by weight, 8-12 parts of waste paper pulp, 8-12 parts of bamboo pulp, 56-84 parts of straw powder, 1-2 parts of biological glue, 1-2 parts of microelement complex fertilizer and 80-120 parts of water which are all pressed and moulded after stewing and mixing. The degradable straw seedling tray and the production method thereof have the advantages of being moderate in hardness, portable, environment-friendly in material, easy to degrade and reusable, and the straw seedling tray can be absorbed by crops as base fertilizer; by the application of the stray seedling tray, the germination rate of the crops is high, roots of seedlings are long, density and root-shoot ratio of the roots are obviously increased, and the survival rate of the cultivated seedlings after planting is high; the production method is scientific and simple, adding of any other chemical raw materials or fertilizer is not needed, characteristics of the raw materials are sustained, and certain fertilizer effect is achieved.

Description

technical field [0001] The invention belongs to agricultural production tools, and mainly relates to a degradable straw seedling raising tray and a preparation method thereof. Background technique [0002] At present, the seedling trays used in agricultural production include plastic trays, resin trays, and pulp trays. Plastic trays cannot be directly transplanted by machine, and cannot be naturally degraded. Manual throwing or secondary transplanting is required. The requirements are very high, and the price itself is expensive, so it is difficult to popularize and implement; the pulp tray is more commonly used now, and its cost is low, but the pulp tray prepared in the prior art has low hardness and strength, and it has rotted in the process of raising seedlings, so it cannot be implemented Machine plug. [0003] The southern part of my country has a lower latitude, sufficient heat and abundant rainfall. The type of cultivated land is paddy field, and the main food crop ...
