Embodiment 1

[0027] The degradable nursery pot provided by the invention is obtained by mixing and sealing crushed plant stalks with livestock and poultry manure biogas slurry, fermenting, compression molding and drying.

[0028] see figure 1 Shown, it is the preparation method flowchart of the degradable seedling pot of the present invention, figure 2 It is a schematic diagram of the structure of the straw seedling-raising bowl-making machine in the present invention, and the method adopted in this embodiment is as follows:

[0029] Step 1. Air-dry the corn stalks naturally, and the water content after air-drying is 13%;

[0030] Step 2, crushing the above corn stalks, the length of which is 5-10cm after crushing, and the length of the crushed corn stalks is longer, which not only saves crushing time and labor, but also saves the input cost of crushing;

[0031] Step 3. Mix the pulverized straw and pig manure biogas slurry in a weight ratio of 1:4 to form a feed liquid, stir until visc...

Embodiment 2

[0038] see figure 2 , which is a structural schematic diagram of a straw seedling raising pot making machine in the present invention. In order to prepare degradable seedling pots, the method used in this embodiment is as follows:

[0039] Step 1. Naturally air-dry the sorghum stalks, and the water content after air-drying is 10%;

[0040] Step 2, crushing the above-mentioned sorghum stalks, the length of the crushed sorghum stalks is 5-10 cm, the length of the crushed sorghum stalks is longer, which not only saves crushing time and labor, but also saves the input cost of crushing;

[0041] Step 3. Mix the pulverized sorghum stalks with cow dung and biogas slurry at a weight ratio of 1:5 to form a feed liquid, stir until viscous, seal and ferment. Here, the present invention uses the weak alkaline environment of the biogas slurry to decompose the sorghum stalks and release a large amount of lignin, thus replacing the chemical binder in the original method for preparing seed...

Embodiment 3

[0048] see figure 2 As shown, it is a structural schematic diagram of the straw seedling raising pot making machine in the present invention. In order to prepare degradable seedling pots, the method used in this embodiment is as follows:

[0049] Step 1. Air-dry the corn stalks naturally, and the water content after air-drying is 15%;

[0050] Step 2, crushing the above corn stalks, the length of which is 5-10cm after crushing, and the length of the crushed corn stalks is longer, which not only saves crushing time and labor, but also saves the input cost of crushing;

[0051]Step 3. Mix the pulverized straw and chicken manure biogas slurry into a feed liquid according to the weight ratio of 1:3, stir until viscous, seal and ferment, and use chicken manure to ferment the biogas slurry to replace the original method of preparing seedling pots The chemical binder in the fertilizer reduces the cost and avoids soil pollution. At the same time, it solves the problem that the chic...

Abstract

The invention provides a novel degradable seedling bowl. The seedling bowl is obtained in the manner that crushed plant straw and poultry excrement biogas slurry are mixed and sealed to carry out fermentation and compression forming, and airing is carried out. A manufacturing method of the novel degradable seedling bowl comprises the following steps that the plant straw is naturally aired, the aired plant straw is crushed, the crushed straw and the poultry excrement biogas slurry are mixed into feed liquid stirred to be thick, sealing and fermenting are carried out, the feed liquid is stirred every other five days, the feed liquid is taken out after fermentation for 40-50 days, and the feed liquid is guided into a die of a straw seedling bowl manufacturing machine to be compressed and formed, the residual feed liquid flows out of a discharging port, demoulding is carried out through an air pump, and the formed seedling bowl is naturally aired. The novel degradable seedling bowl can be degraded and serve as base fertilizer after decomposition, the soil structure is improved, a chemical bonding agent does not need to be added, the agricultural resources are fully utilized, waste liquid discharging is reduced, economic benefit win-win is achieved, heating is not needed in the processing process, energy consumption is reduced, and the machining cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of rural agricultural waste reuse, and in particular relates to a degradable seedling pot and a preparation method thereof. Background technique [0002] The seedling pot has the function of absorbing heat during the day, keeping warm and mulching roots and preserving fertilizer at night, and has the function of water retention during drought. With the rapid development of modern agriculture, the early cultivation of economic plants such as crops, flowers, and seedlings through seedling pots has become an important growth point for farmers' income. However, most of the seedling pots currently on the market are plastic products, which are characterized by low cost, light weight, and good water retention. However, they are not easy to degrade after use, easily cause soil pollution, and have poor air permeability, which is not conducive to the growth of plant roots and causes root damage. , Rotten roots, reduc...
