Description
Technical field
The invention belongs to agricultural wastes recycling field, be specifically related to standby degradable pot for growing seedlings of a kind of straw and preparation method thereof.
Background technology
Stalk fibre is one of reviviscence boiomacromolecule resource that natural world is huge, and the annual stalk fibre output in the whole world is about 40 × 10t, and Chinese stalk resource annual output reaches 7.9 hundred million t.The resource significant wastage adopting the way Treating straw burning or bury to cause and serious problem of environmental pollution are more and more subject to people's attention.A lot of report has been had at present, as fertilizer, novel energy, livestock feed, degradation material, cultivation edible mushroom base-material and build material etc. by straw utilization aspect.
Patent CN104025945A the invention discloses a kind of degradable pot for growing seedlings and production method thereof.This pot for growing seedlings is with biopesticide fermentation residue for primary raw material, and adding portion low water content powder of straw is auxiliary material, finally adds polyvinyl alcohol again, hydroxypropyl methylcellulose is extruded after compounding agent solution stirs, dry and can obtain.In this patent, biopesticide fermentation residue is microbial source biopesticide residue, comprises polyoxin fermentation residue, antibiotic in pyrimidine nucleoside class fermentation residue, jinggangmeisu fermentation residue, Ningnanmycin fermentation residue, Zhongshengmycin fermentation residue or Nikemycin fermentation residue.This pot for growing seedlings is made owing to adopting biopesticide residue, in grow seedlings of vegetable process, easily causes Pesticide Residues in Vegetables to exceed standard, affects the health of eater.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides standby degradable pot for growing seedlings of a kind of straw and preparation method thereof.
The present invention utilizes pachyrhizus stalk, wheat stalk, soybean stalk, cotton stalk, astragalus root dregs, Radix Isatidis residue, and is aided with auxiliary agent, has prepared pot for growing seedlings.Through practice, this pot for growing seedlings has superperformance.And this pot for growing seedlings all by environment fast degradation, can not cause environmental pollution, achieves the comprehensive utilization of stalk.
The present invention is realized by following technical scheme:
The degradable pot for growing seedlings that straw is standby, is prepared from by the raw material of following weight portion:
Pachyrhizus stalk 50-100 part, wheat stalk 50-100 part, soybean stalk 50-100 part, cotton stalk 50-100 part, astragalus root dregs 5-10 part, Radix Isatidis residue 1-5 part, auxiliary agent 0.2-2 part;
Described Radix Astragali residue is according to " Radix Astragali extracts active ingredients and the nanofiltration application study in extraction ", the Radix Astragali residue that in the extraction process described in author Si Dandan, effective component extracting is later;
Described Radix Isatidis residue is the later Radix Isatidis residue of effective component extracting in the extraction process described in " research of Extraction Technology of Radix Isatidis and quality standard " author Shi Xiaoyu.
Described auxiliary agent is polyvinyl alcohol water solution or the hydroxypropyl methylcellulose aqueous solution or its mixture.
The degradable pot for growing seedlings that preferred straw is standby, is prepared from by the raw material of following weight portion:
Pachyrhizus stalk 60-90 part, wheat stalk 60-90 part, soybean stalk 60-90 part, cotton stalk 60-90 part, astragalus root dregs 6-9 part, Radix Isatidis residue 2-3 part, auxiliary agent 0.4-1 part;
The degradable pot for growing seedlings that preferred straw is standby, is prepared from by the raw material of following weight portion:
Pachyrhizus stalk 75 parts, wheat stalk 75 parts, soybean stalk 75 parts, cotton stalk 75 parts, astragalus root dregs 7.5 parts, Radix Isatidis residue 2.5, auxiliary agent 0.8 part;
The mass fraction of described polyvinyl alcohol water solution or the hydroxypropyl methylcellulose aqueous solution is 10-25%.
Selected auxiliary agent is polyvinyl alcohol water solution or the hydroxypropyl methylcellulose aqueous solution or amidin, and its mass fraction is 10-25%, why select above-mentioned auxiliary agent, because above-mentioned auxiliary agent has good adhesive property, above-mentioned various fibers can be combined, improve the bulk strength of material, what adopt is the formulation of its aqueous solution simultaneously, for environment without any impact, very large progress is had than adopting the auxiliary agent of organic solvent dissolution, and above-mentioned polyvinyl alcohol water solution or the hydroxypropyl methylcellulose aqueous solution or amidin polyvinyl alcohol wherein after discarded, hydroxypropyl methylcellulose and starch can complete auto-degradation at short notice, thus realize the fast degradation of whole material, and above-mentioned substance degraded changes the content of soil composition together with fiber, more nutriment is provided, improve the fertilizer efficiency in soil, be conducive to the growth of crop.
The method of the degradable pot for growing seedlings standby with straw described in preparation, comprises following step:
(1) get the Radix Astragali residue of formula ratio, Radix Isatidis residue natural drying is 15-25wt% to water content, being crushed to granularity is
10-200 order, for subsequent use;
(2) get the pachyrhizus stalk of formula ratio, to be crushed to granularity be 10-200 order for wheat stalk, soybean stalk, cotton stalk, keeps moisture to be less than 3wt%;
(3) Radix Astragali residue of step (1) gained, Radix Isatidis residue are joined in the powder of straw of step (2) gained, mixing is, and adds the auxiliary agent of formula ratio;
(4) above mixing of materials evenly after, extruded under the pressure of 5-20Mpa;
(5) namely natural drying obtains finished product to water content lower than 10wt%.
In preferred described step (2), the grinding particle size of stalk is 20 orders.
The insemination and emergence rate of straw seedling breeding pot nursery and root growth situation are the most directly embodying of effect.Insemination and emergence rate high being conducive to reduces sowing seed consumption, reduce production cost, and the root system of prosperity in seedling stage can promote the healthy growth of seedling, is conducive to nurturing staff, improve transplanting survival rate.This result of study shows, when stem shatter granularity is 20 order, the insemination and emergence rate of pot for growing seedlings and saturating radical amount and the longest root long the highest.
In each raw material of the degradable pot for growing seedlings that straw of the present invention is standby, by pachyrhizus stalk, soybean stalk, wheat stalk, cotton stalk composite, pachyrhizus stalk is rich in potassium, soybean stalk, wheat stalk are rich in nitrogen, cotton stalk is rich in phosphorus, make nitrogen in pot for growing seedlings, phosphorus, potassium content all higher, be conducive to emerging and growing up strong and sturdy of seedling.Add Chinese herbal medicine astragalus residue and Radix Isatidis residue in addition, Radix Astragali residue and Radix Isatidis residue are the residues after Chinese herbal medicine astragalus and Radix Isatidis extract principle active component in pharmacy procedure, Radix Astragali residue can promote the growth of seedling, Radix Isatidis residue has bacteriostasis, the effect being similar to biopesticide can be played, prevent seedling from various disease occurring, promote the growth of seedling.
The degradable pot for growing seedlings that straw of the present invention is standby, adopts agricultural wastes crop stem to be raw material, and through simple chemistry and physical modification, mechanical molding is processed and synthesizes a kind of pot for growing seedlings being widely used in crop, vegetables, flowers and forest seedling growth and transplanting.This pot for growing seedlings water storage is functional, alms bowl wall moderate strength, does not need shelling, do not hinder root, no seedling injury after nursery, is convenient to pot seedling transport and integration is planted, can natural decomposition in soil, not only pollution-free to soil, and has certain getting fat effect.
