Problems solved by technology

[0010] The purpose of the present invention is to: aim at the difficulty of demolding the pots and pots existing in the existing processing and making of straws and pots, the success rate is low, or a large amount of release agent needs to be added, or the pots are used for cultivating plants (such as herbs and flowers) It has strong water absorption when cultivated for a long time, and the long-term cultivated plants are easy to absorb water and swell and be damaged. A new method for manufacturing plant straw pots is provided.

Embodiment 1

[0032] In spring, take 1 ton of straw, crush it with a crusher to the straw section below 15cm, soak it in water for 24 hours to infiltrate it, and its moisture content is 60-70%. Add 10kg of urea and 35kg of superphosphate to make the nitrogen content of the material reach about 11g / kg (dry basis), and the phosphorus content is about 2.7g / kg (dry basis), then inoculate 50kg of decomposed chicken manure compost, mix well and then compost decay. The stacking width is 2m, the height is 2m, and stacking with any length makes it decompose. The stacking time is 40 days, and the stack is turned every 3 days during this period.

[0033]After the decomposition is over, take out the material and dry it until the water content is about 40%, crush it with a crusher and sieve it. The aperture of the steel sieve is 5-10mm, and the components under the sieve are kept for making pots and bowls, and the components on the sieve are returned to continue composting and decomposing.

Embodiment 2

[0037] In summer, take 1 ton of straw, crush it with a crusher to the straw section below 15cm, soak it in water for 24 hours to infiltrate it, and its moisture content is about 60-70%. Then add 18 kg of ammonium bicarbonate and 7.0 kg of diammonium hydrogen phosphate to make the nitrogen content of the material reach about 10.5 g / kg (dry basis), and the phosphorus content is about 2.5 g / kg (dry basis), and then inoculate 50 kg of decomposed pig manure compost , mixed evenly and then composted for fermentation. Pile it into a dike with a width of 3m, a height of 2m, and any length. The stacking time is about 30 days, and the piles are turned every 3 days during the stacking period.

[0038] After the composting is completed, take out the materials and dry them in the air until the water content is about 50%, then crush them with a crusher and sieve them. The aperture of the steel sieve is 20-30mm. The undersieve is retained for pots and the oversieve is returned to compost. ...

Embodiment 3

[0042] In autumn, take 1 ton of wheat straw, crush it with a crusher to the straw section below 15cm, soak it in water for 24 hours to infiltrate it, and its moisture content is about 60-70%. Add 18kg of urea and 50kg of superphosphate to make the nitrogen content of the material reach about 13.6g / kg (dry basis), and the phosphorus content is about 3.1g / kg (dry basis). fermentation. The stacking width is 2m, the height is 2m, and the length is arbitrary. The stacking time is 30 days, and the piles are turned every 5 days during the stacking period.

[0043] After the composting is finished, take out the material and dry it until the water content is about 45%, crush it with a crusher and sieve it. The aperture of the steel sieve is 5-10mm. Keep the under-sieve components for making pots and bowls, and the above-sieve parts return to compost.

[0044] Dry the under-sieve components until the water content is about 15%, spray 20kg of materials into 5L of 20g / L gelatin solution...

Abstract

The invention relates to a method for using compost to decay straw to make plant pot. Wherein, it comprises breaking straw into sections; emerging with water; adding nitrogen and phosphor fertilizers; grafting compost product to decay, breaking, screening and adding additive to obtain pot material; compressing and shaping the material, then removing the mould. The inventive pot has strong flexibility. And its surface can be emerged by acrylate emulsion, to be used in plant cultivation. And the invention uses temperature-different demould technique or lift demould technique, to reduce the cost.

Description

Technical field: [0001] The invention relates to a method for making a plant pot, in particular to a method for making a plant pot by composting and decomposing straw. Background technique: [0002] Crop straw is a degradable biomass material, which has been used to make degradable seedling containers and plant cultivation pots in recent years. [0003] Chinese Patent Publication No. CN1125502 introduces a manufacturing method of a plant straw seedling raising container, which includes the steps of drying, crushing, grading, and heating and pressing molding steps in a mold with crushed plant straw as a raw material. It is characterized in that when hot pressing The crushed particle size of plant straw is between 0.4-0.5mm, the water content of raw materials is <15%, the heating temperature of the mold is 170-210°C, and the mold pressure is 10-15kg / cm 2 , Mold taper 1:1.8~1:2.4. The existing defects are as follows: 1. The crushing fineness of the straw is high and consum...
