Problems solved by technology

However, although the seedling pots prepared by this method can achieve the purpose of degradation, since the raw materials constituting the seedling pots are mainly sludge or sludge compost products, the produced seedling pots can only be small in wall thickness and volume. Bowl
The seedling pot has the disadvantages of small volume, unfavorable growth of seedlings, bulky, inconvenient use and unfavorable for large-scale popularization and use.

Embodiment 1

[0014] Utilize above-mentioned raw material to prepare the processing step of fully degradable high-efficiency seedling-raising pot and comprise the following steps:

[0015] First prepare the waterproofing agent: namely

[0016] Weigh 100 parts by weight of polyvinyl alcohol, add 500 parts by weight of water, heat to about 85°C for dissolution, then add 100 parts by weight of urea, and then add 10% hydrochloric acid to adjust the pH value of the solution to 2, and The solution is heated to about 80°C for full reaction, and finally sodium hydroxide solution is added to make the pH value of the above solution reach 7.

[0017] The preparation steps of the fully degradable high-efficiency seedling pot are as follows:

[0018] Weigh 73 kg of straw powder with a length of 0.5-3.0 mm, 18 kg of fly ash, 5 kg of urea-formaldehyde resin as a binder and 0.06 kg of ammonium chloride as a curing agent, first mix the urea-formaldehyde resin and ammonium chloride Finally, put the mixture...

Embodiment 2

[0020] First prepare the waterproofing agent: namely

[0021] Weigh 100 parts by weight of polyvinyl alcohol, add 1500 parts by weight of water, heat to about 85°C for dissolution, then add 50 parts by weight of formaldehyde, and then add 10% hydrochloric acid to adjust the pH value of the solution to 2, and The solution is heated to about 80°C for full reaction, and finally sodium hydroxide solution is added to make the pH value of the above solution reach 7.

[0022] The preparation steps of the fully degradable high-efficiency seedling pot are as follows:

[0023] Weigh 70 kg of straw powder with a length of 0.5-3.0 mm, 20 kg of fly ash, 8 kg of epoxy resin as a binder and 0.05 kg of ammonium sulfate as a curing agent, first mix the epoxy resin and ammonium sulfate Finally, put the mixture, straw powder, and fly ash into a high-speed mixer, stir for 5 minutes, take it out as a hot-pressed material, weigh 20 grams of hot-pressed material and add it to the mold at a hot-pres...

Embodiment 3

[0025] First prepare the waterproofing agent: namely

[0026] Weigh 100 parts by weight of polyvinyl alcohol, add 1000 parts by weight of water, heat to about 85°C for dissolution, then add 300 parts by weight of urea, and then add 10% hydrochloric acid to adjust the pH value of the solution to 1. The solution is heated to about 80°C for full reaction, and finally sodium hydroxide solution is added to make the pH value of the above solution reach 7.

[0027] The preparation steps of the fully degradable high-efficiency seedling pot are as follows:

[0028] Take by weighing 75 kilograms of stalk powder, 15 kilograms of fly ash, 7 kilograms of urea-formaldehyde resin as a binder and 0.025 kilograms of ammonium sulfate as a curing agent with a length of 0.5-3.0 millimeters. After mixing the urea-formaldehyde resin and ammonium sulfate, Put the mixture, straw powder, and fly ash into a high-speed mixer again, stir for 5 minutes, take it out as a hot-pressed material, weigh 20 gra...

Abstract

The invention belongs to the technical field of seedling growing tools, in particular discloses a full-degradation high-manurial-effect seedling growing pot which is made by mould unloading and mold hanging after heat pressing vulcanization of straw powder, coal ash, adhesives, curing agent and waterproofing agent which are mixed, agitated and then filled into a die. Because the main materials of the seedling growing pot substantially include straw powder and coal ash, the purpose of returning straws to fields is achieved, and fertilizer elements such as kalium and phosphor and metallic elements such as ferrum, calcium, magnesium, zinc, titanium, sulfur and the like contained in coal ash can be utilized, which facilitates reconstruction of soil. Besides, all raw materials of the seedling growing pot can be degraded to fertilizers such as organic matter, humic acid, phosphate fertilizer, potassium fertilizer and the like, which can further improve the fertility of soil and facilitate the growth of seedlings.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising utensils, and in particular relates to a fully degradable and high-efficiency seedling-raising pot and a preparation method thereof. Background technique [0002] At present, in the planting process of crops, vegetables, flowers, and fruit trees, in order to improve the utilization rate of land and the yield of crops, the planting technology of using seedling pots to breed seedlings and then transplanting the seedlings into the field is being promoted. Due to factors such as production cost and production technology, the seedling pots used for breeding seedlings are mostly made of plastic materials. And due to the characteristics of the plastic itself, there are the following difficulties in the promotion of this agricultural technology: one, the seedlings planted in the seedling pot, because the roots cannot break through the wall of the seedling pot, when transplanting the seedlings in ...
