AI Technical Summary

Problems solved by technology

The nutritional pots are all single pots, which are not suitable for the needs of automatic transplanting machines for orderly seedling cultivation and orderly transplanting
[0004] In addition, most of the existing biomass molding materials for seedling raising are prepared from crop stalks and clay. Adding chemical glue, biological glue or clay is not only not environmentally friendly, but also costly, and the transportation of raw materials is not cheap, etc.
Due to the poor strength of the molding material of the existing animal feces biomass bowl tray, although the multi-position single bowl or seedling raising block can be completely degraded, it cannot realize automatic, accurate and orderly supply of seedlings due to its disorder. Unable to meet the needs of automatic transplanting

Embodiment 1

[0018] A seedling-raising biomass molding material of the present invention prepares special-purpose seedling-raising pots for corn or vegetables, which is achieved through the following steps:

[0019] a. Heating: heat 50-100 parts of cow dung and 0-50 parts of rice straw to 170-270°C, and the preferred temperature is above 190°C;

[0020] b. Compression: subject the material prepared in step a to a pressure of 10-30Mpa, at constant temperature and pressure for 15s-40min;

[0021] c. Molding: cooling the material compressed in step b to below 60°C, the preparation of the bio-molding material is completed.

Embodiment 2

[0023] A seedling-raising biomass molding material of the present invention is used to prepare rice special-purpose seedling-raising pots and pans, which is achieved through the following steps:

[0024] a. Heating: Evenly mix 95 parts of cow dung and 5 parts of corn stalks;

[0025] b. Compression: heat the material obtained in step a to 260-270°C under a pressure of 10-30Mpa, and hold constant temperature and pressure for 15s-40min; The lignin in cow dung is in an elastic-plastic state. When the temperature is higher than 70 degrees Celsius, the lignin starts to soften. When the temperature continues to rise to 170 degrees Celsius, the lignin softens rapidly and reaches a liquefied state and has fluidity. Under the action, the lignin in the cow dung is precipitated and fused with the cellulose in the cow dung and the cellulose in the straw, so that the physical structure of the biomass material is reorganized;

[0026] c. Molding: Cool the material compressed in step b to b...

Embodiment 3

[0028] The preparation of rice seedling pots with a thickness of 2 to 3.5 mm is achieved through the following steps:

[0029] a. Heating: Evenly mix 90 parts of sheep manure and 10 parts of soybean straw, and control the comprehensive moisture content at 30-36%;

[0030] b. Compression: Heat the material prepared in step a to 240-250°C under a pressure of 20Mpa, and keep the temperature and pressure constant for 1-5 minutes;

[0031] c. Molding: cooling the material compressed in step b to below 60°C, the preparation of the bio-molding material is completed.

Abstract

A seedling-raising biomass molding material and its preparation method of the present invention relate to the preparation of soil nutrition pots for seedlings, which are made from 50 to 100 parts of cow dung or sheep manure and 0 to 50 parts of cellulose-containing straw, which are realized through the following steps Process: After mixing 50-100 parts of cow dung or sheep manure and 0-50 parts of cellulose-containing biomass, continue heating to 170-270°C under a pressure of 10-30Mpa, keep the temperature and pressure for more than 15s, and then cool down When the temperature is below 60°C, the preparation of bio-forming materials is completed. The seedling-raising biomass molding material of the present invention reduces the steps of removing the plastic seedling pots during the transplanting process, does not slow down the seedlings, prolongs the effective growth period of crops, and has good water permeability and air permeability, and the root system of seedlings is easy to penetrate. , which is beneficial to the growth and development of seedlings, can be transplanted together with seedlings, and can be naturally degraded after transplanting. At the same time, straw decomposes and straw improvement materials can significantly improve soil physical and chemical properties. This material can be completely degraded, without any adhesive added, and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to the preparation of a soil nutrition pot for seedlings, in particular to a seedling raising biomass molding material and a preparation method. Background technique [0002] Heilongjiang is located in a high latitude zone, with poor climate, soil and other environmental conditions, short frost-free period, and short corn growth period. Planting corn with corn pot breeding and transplanting technology can increase the growth period of corn by 10-15 days, which can alleviate the problems of low accumulated temperature and short growth period in northern my country. It is one of the effective production methods to improve the yield and quality of corn, and has the effect of increasing production and income . Traditional seedling raising and transplanting methods are inefficient, and mechanized transplanting can reduce labor intensity and improve transplanting efficiency. In mechanized seedling raising and transplanting, the use of ...
