Mechanical transplanting rice seedling substrate and growth method thereof

Abstract

The invention discloses a mechanical transplanting rice seedling substrate and a growth method thereof. The formula of the mechanical transplanting rice seedling substrate comprises the following components in percentage by mass: 60-80% of brewing industrial sludge, 15-25% of straw carbon, 5-10% of special clay and 0.8-5% of a seedling strengthening agent. The production of the substrate comprises the following steps: (1) fermentation drying; and (2) blending and crushing. The mechanical transplanting rice seedling substrate disclosed by the invention has the advantages that the fermentation drying cycle is short, the utilization ratio of a fermentation workshop is high, a small space is occupied, the production batch is large, the energy consumption is low, the labor is less, the cost is low, the material decaying heat degree is high, the raw materials used for the seedling substrate are stable in quality, the phenomena of secondary fermentation and root injuring bacterium burning are avoided, the moisture and fertilizer retention capabilities of the seedling substrate are improved, and two bottleneck problems of green withered seedlings and later-stage limb force senesced yellowing of a general seedling substrate are solved.

Description

technical field [0001] The invention particularly relates to a machine-transplanted rice seedling raising substrate and a growth method thereof. Background technique [0002] At present, the centralized rice seedling raising has solved the bottleneck problem of the popularization of rice machine transplanting, but the centralized seedling raising has also encountered difficulties such as difficulty in taking soil, difficulty in cultivating fertilizer, and damaged cultivated land. For this reason, in recent years, many units have developed rice seedling raising substrates of different types and materials, trying to solve the problem of soil source for large-scale concentrated seedling raising by using soilless seedling raising methods, but few of them have been transformed into industrial products and mass production. production case. [0003] Its main problems are reflected in: [0004] 1. The agricultural organic waste is primary wheat and corn stalks. It is difficult to ...

AI Technical Summary

Problems solved by technology

[0004] 1. The agricultural organic waste is primary wheat and corn stalks. It is difficult to collect primary husks and edible fungus residues. The fermentation cycle is long and the fermentation is not complete, but it takes up a large area of ​​land and high cost;

[0005] 2. Using peat as the main material of the matrix has long transportation distance and high cost, which is difficult for farmers to bear and is not renewable;

[0006] 3. Using urban waste as the main material of the matrix, the problem of heavy metal pollution cannot be solved;

[0007] 4. Using industrial organic waste residues such as wine residues, vinegar residues, and biogas residues as the main material of the matrix, although it is easy to obtain materials, often because the organic matter will exceed the standard, the phenomenon of secondary fermentation root damage and burning bacteria often occurs, and the ability to retain water and fertilizer is poor. If you don't pay attention, there will be problems of dead seedlings and yellow limbs in the later stage

At the same time, this kind of organic waste residue has a high water content (>75%), and the fermentation and drying process is greatly affected by weather conditions, which is labor-intensive and time-consuming. The output is low and unstable, and it is difficult to batch
