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, 1 ton of straw is taken, crushed to a straw section below 15 cm with a crusher, soaked 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 of about 2.7g / kg (dry basis), and then inoculate 50kg of decomposed chicken manure compost, mix well and compost Decompose. The stacking width is 2m, the height is 2m, and the stacking length is arbitrary to make it decompose. The stacking time is 40 days, during which the stacking will be turned over every 3 days.

[0033]After the decomposition, the materials are taken out and aired until the moisture content is about 40%, crushed with a crusher and sieved. The aperture of the steel sieve is 5-10mm, the components under the sieve are reserved for making pots, and the upper sieve is returned to continue composting and decomposing.

[0034] The components und...

Embodiment 2

[0037] In summer, 1 ton of straw is taken, crushed to a straw section below 15cm with a crusher, soaked in water for 24 hours to infiltrate it, and its moisture content is about 60-70%. Then add 18kg of ammonium bicarbonate and 7.0kg of diammonium hydrogen phosphate to make the material nitrogen content reach about 10.5g / kg (dry basis) and phosphorus content about 2.5g / kg (dry basis), and then inoculate 50kg of decomposed pig manure compost , After mixing evenly, compost and ferment. Stack it into a bank with a width of 3m, a height of 2m, and an arbitrary length. The stacking time is about 30 days, and the stacking is turned over every 3 days during the stacking period.

[0038] After composting, the materials are taken out and aired until the moisture content is about 50%, crushed with a crusher and sieved. The aperture of the steel sieve is 20-30mm. The components under the sieve are reserved for making pots, and the components on the sieve are returned to the compost.

Embodiment 3

[0042] In autumn, take 1 ton of wheat straw, use a crusher to crush 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 material have a nitrogen content of about 13.6g / kg (dry basis) and a phosphorus content of about 3.1g / kg (dry basis), and then inoculate 50kg of decomposed cow manure for composting, and mix it evenly. System fermentation. The stacking width is 2m, the height is 2m, and the length is arbitrary. The stacking time is 30 days, and the stacking is turned over every 5 days during the stacking period.

[0043] After composting, the materials are taken out and aired until the moisture content is about 45%, crushed with a crusher and sieved. The aperture of the steel sieve is 5-10mm. The components under the sieve are reserved for making pots, and the upper sieve is returned to the compost.

[0044] The components under the sieve are aired until the...

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 plant pots, in particular to a method for making plant pots by using compost to decompose straw. technical background: [0002] Crop straw is a degradable biomass material. In recent years, people have used it to make degradable nursery containers and plant cultivation pots. [0003] Chinese Patent Publication No. CN1125502 introduces a method for manufacturing a plant straw seedling raising container. The method includes the steps of using crushed plant straw as a raw material, drying, crushing, and grading, and heating and pressing in a mold. The crushing particle size of plant straw is between 0.4~0.5mm, the water content of the raw material is less than 15%, the heating temperature of the mould is 170~210℃, and the mould pressure is 10~15kg / cm 2 , Mold taper 1:1.8~1:2.4. The existing defects are: 1. The straw crushing requires high fineness and high energy consumption; 2. The container needs to be pressed at...
