Problems solved by technology

The disadvantages are: 1. The crushing fineness required by the straw is high and consumes a lot of energy; 2. Heating is required during the container forming process, which requires heating equipment and consumes energy; Influence, in particular, does not take into account the influence of the container wall on the root penetration of the plant
Disadvantages: 1. The plant stalks used are relatively simple, only corn and sunflower stalks; 2. The container making process is manual operation, which is not suitable for large-scale industrial production; effect, especially without considering the effect of the container wall on the root penetration of the plant

example 1

[0019] Weigh 1000kg of straw, spray 300kg of quicklime water with a concentration of 10%, wet all the straw, and cover it with a plastic film to prevent it from getting wet when it rains; stack it to soften, when stacking, each pile is 1-3 meters, and stack it in summer 5-7 days, stacking for 10-15 days in spring and autumn, 15-20 days in winter, turning 1-2 times in the middle. The softened stalk is pulverized to fiber at normal temperature. Use a chain crusher to pulverize to a fiber shape with a length of 5-15 mm, place it in a mixer, spray about 100 kg of waste sulfuric acid with a concentration of 10%, and adjust the pH to about 6. Add 80kg of water-quenched slag ball mill powder, 2kg of amino acid medium and trace element chelate salts, and 1kg of powdery superabsorbent resin and stir evenly. The mixed material is placed in a mold and pressed into a mold. The mold used is a mother mold on the outside and a tire mold on the inside. There are several small protrusions dis...

example 2

[0021] Weigh 1000kg of water wheat straw, spray 600kg of 2% potassium hydroxide lye, wet all the water wheat straw, and cover it with plastic film to prevent it from raining; rice, stacked for 5-7 days in summer, 10-15 days in spring and autumn, and 15-20 days in winter, and turned 3 times in the middle. The softened stalk is pulverized to fiber at normal temperature. Use a chain crusher to grind it into a fibrous shape with a length of 5-15mm, put it in a mixer, spray about 200kg of phosphoric acid with a concentration of 15%, adjust the pH at about 6, add 50kg of water-quenched slag ball mill powder, and 1kg of powder Stir the superabsorbent resin evenly. Put it in a mold and press it into shape, which can be pressed by hydraulic press, hydraulic press or screw extruder. After pressing, it can be dried or naturally air-dried to be a finished product.

example 3

[0023] Weigh 1000kg of straw, spray 400kg of 5% lime slurry at a concentration of , wet all the straw, and cover it with a plastic film to prevent it from getting wet when it rains; stack and soften, and when stacking, each pile is 10-3 meters, stacking in summer 5-7 days, stacked for 10-15 days in spring and autumn, 15-20 days in winter, and turned twice in the middle. The softened stalk is pulverized to fiber at normal temperature. Use a chain crusher to pulverize to a fiber shape with a length of 5-15mm, place it in a mixer, spray 130kg of 10% waste sulfuric acid, adjust the pH to about 6, add 80kg of water-quenched slag ball mill powder, 2kg of amino acids, Trace element chelate salt, 1.5kg of urea-formaldehyde resin, and 1kg of powdered polyacrylamide were stirred evenly. Put it in a mold and press it into a mold. You can use a hydraulic press, a hydraulic press or a screw extruder. After pressing, it can be dried or naturally air-dried to be a finished product.

Abstract

The plant stalk pot making process has simple apparatus used, less investment and low cost, and the plant stalk pot is used in cultivating and transplanting seedling and becomes fertilizer for the plant after degradation. The making process includes adopting plant stalk as main material, adding alkali solution to raise pH value to over 9, stocking for softening, crushing, adding acid solution to regulate pH to neutral, mixing with additive, molding, demolding, and drying. The weight ratio among plant stalk, alkali solution, acid solution and additive is 1 to 0.2-0.6 to 0.06-0.2 to 0.02-0.08. The present invention is suitable for cultivating seedling and pot cultivation.

Description

Technical field: [0001] The invention relates to a manufacturing method of a pot for plant cultivation, which is suitable for container seedling cultivation and pot cultivation, and belongs to a process method for resource utilization of straw and manufacture of a pot for plant cultivation. Background technique: [0002] As a renewable resource, plant straw is only produced 600 million tons of crop straw in the country every year. In the era of shortage of rural energy supply, straw is mainly used as fuel. However, in recent years, with the development of new rural energy sources, such as: , natural gas and other applications, coupled with the increase in the output of crop straws, there is a large surplus of straws, and the pollution of the air, water bodies, and rural areas due to straw field burning or random abandonment is becoming more and more serious. Therefore, it is very important to seek new technologies and new approaches for straw disposal. [0003] In the culti...
