Description
Technical field
The invention belongs to rural and agricultural discarded object reutilization technology field, be specifically related to a kind of novel degradable pot for growing seedlings and preparation method thereof.
Background technology
Pot for growing seedlings has heat absorption on daytime, is incubated the effect of mulch, fertilizer conservation night, has water retention during arid.Along with the fast development of modern agriculture, cultivated in early days economic plants such as crops, flowers, nursery stocks by pot for growing seedlings, this agricultural Model becomes the important growth point promoting farmers' income.But the pot for growing seedlings sold in the market mostly is plastic products, is characterized in that cost is low, quality light, good water-retaining property, but not easily degrades after using, easily cause soil pollution, poor air permeability, be unfavorable for the growth of root system of plant, cause hindering root, rotten, reduce transplanting survival rate.Along with country is to the attention of living resources, employing maize straw is that the degradable pot for growing seedlings of raw material replaces plastic seeding culturing alms bowl to be the inexorable trend developed.
For the problems referred to above, a lot of researcher has invented multiple pot for growing seedlings, and has carried out analysis optimization to the relevant parameter of straw seedling breeding pot.
" experimental study of the shaping pot for growing seedlings of straw extrusion " (" agricultural research " the 2nd phase in 2008) that the Bai Xiaohu of Agricultural University Of Shenyang etc. deliver, after corn straw smashing is sieved, add appropriate binding agent, adopt extrusion forming process to make degradable straw seedling breeding pot.The method needs to use a large amount of starch, boric acid and formaldehyde as binding agent raw material in manufacturing process, and wherein formaldehyde has contamination for soil, and therefore unsuitable large-scale popularization uses.
China Patent Publication No. CN1271039A disclosed " a kind of vegetable fiber containing product and preparation method thereof ", employing vegetable fiber is primary raw material, and cereal starch is as binding agent, and rapeseed oil or food-grade paraffin wax are remover.Need in this production method process with using a large amount of cereal starch and rapeseed oil, this adds production cost undoubtedly, even if use paraffin to reduce costs to a certain extent, but paraffin is not easily degraded in soil, can cause secondary pollution, spoiled soil structure.
Describing in China Patent Publication No. CN125502A disclosed " a kind of manufacture method of straw container for plant growth " adopts waste plant straws to be raw material, through super-dry, pulverizing, classification, finally in mould, heats extrusion forming.The main machined parameters of the method: straw grinding particle size is 0.4-5.0mm, mold heated temperature is 170-210 DEG C, and applying pressure is 10-15kg/cm
2.As can be seen from its machined parameters, straw pulverizing requires high, and power consumption is large; In hot-forming process, heating-up temperature is high, and production cost is high.
In view of above-mentioned defect, creator of the present invention, through research and test for a long time, finally obtains the present invention.
Summary of the invention
The object of the present invention is to provide a kind of novel degradable pot for growing seedlings and preparation method thereof, in order to overcome above-mentioned technological deficiency.
For achieving the above object, the technical solution used in the present invention is: first provide novel degradable pot for growing seedlings in, and this pot for growing seedlings carries out fermentation by the straw pulverized and the liquid mixing sealing of feces of livestock and poultry natural pond and compression forming obtains after drying.
Wherein, the water content of described stalk is 10-15%, and after pulverizing, length is 5-10cm.
Wherein, the weight ratio that described straw mixes with described feces of livestock and poultry natural pond liquid is 1:(3-5).
Secondly, a kind of preparation method of novel degradable pot for growing seedlings is provided, comprises the steps:
Step 1, straw natural air drying to water content is 10-15%;
Step 2, described air-dry straw to be pulverized;
Described stalk after step 3, pulverizing and feces of livestock and poultry natural pond liquid are mixed into feed liquid, are stirred to thickness, and sealing is fermented;
Step 4, every 5 days, feed liquid to be stirred, make it fully ferment;
Step 5, fermentation, after 40-50 days, take out this feed liquid, import in the mould of straw seedling breeding pot machine for making pots and carry out compression forming, and applying pressure size is 20-50kg/cm
2;
Step 6, by residue feed liquid flow out from the discharging opening of described mould;
Step 7, air pump is utilized to carry out the demoulding, by shaping pot for growing seedlings natural air drying.
Wherein, described feces of livestock and poultry is at least any one in pig manure, cow dung or chicken manure.
Wherein, described straw is corn, wheat, at least one in paddy rice, jowar stalk.
Beneficial effect of the present invention is compared with the prior art: the pot for growing seedlings in (1) this programme can be degraded, and can be grafted directly in soil, as base fertilizer after pot for growing seedlings decomposition, improves soil structure; (2) mild alkaline conditions of natural pond liquid is utilized to carry out preliminary exposition to maize straw, discharge a large amount of lignin, therefore instead of original Chemical Felter prepared in pot for growing seedlings method, reduce cost, solve the processing procedure could regarded liquid fertilizer or be discharged after livestock manure fermented liquid has to pass through biological treatment simultaneously, make full use of agricultural resources, reduce discharging of waste liquid and realize economic benefit doulbe-sides' victory; (3) the whole process of the technical program does not need heating, can operate at normal temperatures, saves energy consumption, cuts down finished cost.
