Embodiment 1

[0020] 1. The preparation ratio of environmentally friendly starch adhesive: Dissolve 160g of starch in 192mL of water, mix well, add 4.5mL of 3% hydrogen peroxide and 0.31g of sodium bicarbonate, stir well, then gradually add 60mL of 10% sodium hydroxide solution, Stir to dissolve the starch glue.

[0021] 2. Pretreatment of water hyacinth and rice straw: Use solar and wind energy to dry water hyacinth and rice straw naturally until the water content is less than 15%, and then chop it. The longest length should not exceed 1cm.

[0022] 3. Proportion (weight ratio) of seedling pot materials: water hyacinth 70%, rice straw 25%, adhesive 5%).

[0023] 4. Production process: starch preparation - water hyacinth and rice straw preparation (drying and chopping) - mixing water hyacinth and straw evenly - slowly adding adhesive while stirring - importing seedling pot mold - extrusion Forming - Trimming - Drying.

Embodiment 2

[0025] 1. The preparation ratio of environmentally friendly starch adhesive: Dissolve 200g of starch in 350mL of water, mix well and add 7.0mL of 3% hydrogen peroxide and 0.48g of sodium bicarbonate. Stir evenly, then gradually add 92 mL of 10% sodium hydroxide solution, and stir to dissolve to obtain starch glue. For different requirements, calculate according to the above proportion ratio.

[0026] 2. Pretreatment of water hyacinth and rice straw: dry the water hyacinth and rice straw until the water content is less than 15%. should.

[0027] 3. Proportion (weight ratio) of seedling pot materials: 100% of water hyacinth, 0% of rice straw, and 1% of adhesive.

[0028] 4. Production process: starch preparation - water hyacinth and rice straw preparation (drying and chopping) - mixing water hyacinth and straw evenly - slowly adding adhesive while stirring - importing seedling pot mold - extrusion Forming - Trimming - Drying.

Embodiment 3

[0030] 1. The preparation ratio of environmentally friendly starch adhesive: Dissolve 100g of starch in 180mL of water, mix well and add 3.5mL of 3% hydrogen peroxide and 0.25g of sodium bicarbonate. After stirring evenly, gradually add 47mL of 10% sodium hydroxide solution. Stir to dissolve the starch glue. For different requirements, calculate according to the above proportion ratio.

[0031] 2. Pretreatment of water hyacinth: use solar energy and wind energy to dry water hyacinth and rice straw naturally, with a water content of <15%. The fineness of the straw and water hyacinth can vary, but the maximum should not exceed 1.5cm. .

[0032] 3. Proportion (weight ratio) of seedling pot materials: 85% of water hyacinth, 12.5% ​​of rice straw, and 2.5% of starch adhesive.

[0033] 4. Production process: starch preparation - water hyacinth and rice straw preparation (drying and chopping) - mixing water hyacinth and straw evenly - slowly adding adhesive while stirring - import...

Abstract

The invention discloses a planter culture method in greenhouse using waterhyacinth, comprising: dissolving starch in water; adding hydrogen peroxide and sodium bicarbonate into the uniform mixing liquid of starch and water; adding sodium hydroxide solution into uniformly stirred mixing liquid; obtaining starch glue after stirring and dissolving; guiding starch glue into a bowl module; compacting by extrusion and drying after flange trimming. The bowl culture method can effectively solve the waterhyacinth resource problem and replace the plastic bowl widely used in the prior greenhouse culture and solve the waterhyachinth utilization path and eliminate the pollution of traditional bowl greenhouse culture and resource waste, with wide market development foreground and economic benefit.

Description

technical field [0001] The invention relates to a method for making seedling pots for greenhouse cultivation by using water hyacinth. Background technique [0002] The eutrophication of the water body leads to the flooding of the water hyacinth and the further pollution of the water body. The main reason why it cannot be cured so far is that there is no effective and reasonable way to treat and utilize it: such as the introduction of the natural enemy of the water hyacinth, the weevil beetle, etc. for ecological control. It may lead to new ecological disasters that need to be demonstrated; the use of chemical herbicides will cause new pollution to water bodies; as feed for livestock and poultry such as pigs and ducks, it will gradually fade out due to high water content and low edible ingredients; extracting nutrients from it will face challenges. Barriers to high costs. On the other hand, the use of a large number of plastic seedling pots in greenhouse production (mainly i...
