A kind of straw bio-substrate seedling raising tray and preparation method thereof

Abstract

The invention provides a straw biological matrix seedling-raising disk and a preparation method thereof. The straw biological matrix seedling-raising disk includes a seedling-raising disk and a bottom film arranged thereunder. A matrix is filled between the seedling-raising disk and the bottom film. The seedling-raising disk includes waste paper pulp, bamboo pulp, straw powder, bio-gum, a composite micro-fertilizer and water. The matrix includes plant straw, a straw fermentation agent, an additive, a seedling strengthening agent and water. The bottom film is a bast fiber mulching film. The seedling-raising disk is simple and scientific in preparation method and is free of addition of any other chemical raw materials or fertilizers, so that the seedling-raising disk keeps the characters of the raw materials and has a certain effect. The technical scheme replaces soil and a plastic seedling-raising disk by the straw biological matrix, which reduces the damage of white pollution. By means of the straw biomass for culturing seedlings of paddy rice for replacing the technology of seedling cultivation in nutrient soil in production over the years, the seedling-raising disk solves the problem that cultivated land is damaged and soil is difficult to obtain by farmers during a paddy rice seedling-raising process. The seedling-raising disk fully utilizes straw regenerated resources, thereby reducing environment-pollution due to straw incineration and achieving energy saving and emission reduction.

Description

technical field [0001] The invention belongs to agricultural production tools, and mainly relates to a straw biological matrix seedling raising tray and a preparation method thereof. Background technique [0002] The transplanting technology of dry rice seedlings with soil was introduced in Japan in the 1970s. It has been popularized in my country for more than 30 years. Due to the continuous large amount of soil borrowed for many years, the ecological vegetation such as farmland and cultivated land has been seriously damaged. Taking the three northeastern provinces as an example, the area of ​​paddy fields is more than 96 million mu, and 35 million cubic meters of high-quality topsoil have to be excavated every year. Calculated by digging 10 cm of topsoil, nearly 450,000 mu of topsoil is dug away every year. The environmental protection tray produced by using straw has completely solved the problems of farmers taking soil for seedling cultivation, destroying vegetation and ...

AI Technical Summary

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
