Abstract
The invention discloses a kind of completely degradable water retaining mulching of fruit residue humic acid and production method thereof, this technology is produced high reactivity BHA with solid-state fermentation technology earlier, utilizes the starch based industrial residue of biological pesticide enterprise to produce the completely degradable water retaining mulch film again.Its process comprises: the pulverizing of (1) BHA raw material, the solid state fermentation under fungi (Trichoderma, black aspergillus), yeast composite bacteria effects such as (open and flat aspergillus, aspergillus sydowiis); (2) pre-treatment of starch based industrial residue is with film-forming properties processing and the packing and storing of high reactivity BHA.The BHA-high reactivity completely degradable water retaining mulch film purposes of this explained hereafter is wide, and cost is low, has both helped the apple place of production or has added the conservation of natural environment in building site; More help the soil moisture conservation volume increase of China western severe cold water-deficient area farm crop.
Description
Technical field
The present invention relates to a kind of completely degradable water retaining mulch film and production method thereof.
Technical background
At apple product, pin and a large amount of apple peel of processing area meeting generation, these apple peels mainly are made up of Pericarpium Mali pumilae, apple seed and stalk, leaf and the fruit of rotting, and will have a strong impact on physical environment as not dealing carefully with.Recent studies show that, contains the high polyphenolic substance of added value in the Pericarpium Mali pumilae, has multiple pharmacological effect such as anticancer, anti-oxidant, arteriosclerosis.Apple residue is except being used for feed (needing the strict pesticide residue that detect) on a small quantity at present, and major part is directly used in the production of fertilizer.
The pomace humic acid organic fertilizer of bibliographical information is produced, generally similar to weathered coal humic acid, stalk humic acids (as: Chinese patent CN 1182797A, CN1232831A).Do not note character, screening and microorganisms bacterial classification according to raw material and product characteristic component.Therefore, except using conventional humic acids content not ≮ 50%, or contain inorganic fertilizer elements such as N, P, K, or contain trace elements such as Cu, Fe, Zn and represent outside its high reactivity, be difficult to characterize pomace humic acids (abbreviation BHA with the content of plant growth hormoness such as indolic acid, dormin, high reactivity down together) and diversity (agricultural chemicals of holding concurrently) are unfavorable for production and the application of high added value BHA.
Membrane covering is a kind ofly to improve the cultivation technique of crop growth environment with manual method, and this method can prevent soil water evaporation, suppresses weed growth, improves crop to light, temperature, water, fertile and land utilization ratio etc. comprehensively.The present kind of China is few.
For avoiding " white pollution ", the applying starch base, comprise that it is a kind of trend that Wholly-degradable materials such as poly(lactic acid) are made the environmental type material.But because such material cost height, toughness is relatively poor, and is existing except as the hospital surgical material, outside a small amount of packaging material for food, generally is not used for mulch film production.Chinese patent CN1459471 discloses a kind of liquid-state mulch film with stalk-humic-acid kind material preparation, can improve field temperature 1-4 ℃, finally can turn fertilizer, not contaminated soil into.But it also slightly is worse than plastic films such as PE, PS on use propertieies such as insulation moisture-resistant.
Summary of the invention
The purpose of this invention is to provide a kind of completely degradable water retaining mulching of fruit residue humic acid and production method thereof, to overcome the above-mentioned defective that prior art exists.
The production method of BHA-high reactivity completely degradable water retaining mulch film of the present invention comprises the steps:
(1) will extract apple peel behind the polyphenolic substance, and add the water of 2～10 times of weight and N, P, K nutritious cpds, sterilization is inoculated in fungal spore or yeast in the above-mentioned mixture then, cultivates 24-56 hour for 15～40 ℃, obtains liquid spawn;
The method that apple peel extracts polyphenolic substance is published in " Xibei Univ. of Agricultural ﹠ Forest Science ﹠ Technology's journal; 33 (8) 2005:131-134 " at Li Zhixi, Li Yuanrui etc., Guo Juan etc. have similar play-by-play in " foodstuffs industry science and technology 2006 (2): 178-180 " document.
Said nutritious cpds is the material that contains N, P and K, preferably sulfuric acid ammonium, dipotassium hydrogen phosphate, Repone K, starch, comes from nitrogen compound in the apple amino acid, the auxiliary material kitchen excess and contains phosphorus component or plant ash, and absolute composition addition is 10～20mg/L;
Said fungi is Trichoderma (Trichoderma viride) or black aspergillus (Aspergillus, nigervan tienghem), yeast is preferably (Aspergllus oryzae Ass.3944), above-mentioned fungi or yeast are provided by Chinese microbial preservation center, or the commercialization bacterial classification that adopts GuanShengYuan, Shanghai group company to produce;
According to the present invention, can with spore inoculating after extracting polyphenolic substance apple peel and the mixture of plant stem-leaf, plant stem-leaf is selected from more than one in fragrant plant thatch, reed cauline leaf, folder branch peach leaf or the two look Stem or leaf of Shrub Lespedeza;
(2) plant stem-leaf after will pulverizing and extract polyphenolic substance after apple peel, the liquid spawn that obtains with the step (1) of 0.01-0.1 times of weight mixes, under anaerobic, in 20～30 ℃, fermented 6～10 days, acquisition contains the high reactivity BHA of components such as indolylacetic acid, dormin, and then with tonality material mixed milling, obtaining viscosity is the mulch film work in-process of 1～100,000 centipoise;
Said plant stem-leaf is selected from more than one in fragrant plant thatch, reed cauline leaf, folder branch peach leaf or the two look Stem or leaf of Shrub Lespedeza;
The parts by weight of the apple peel behind leaf and the extraction polyphenolic substance are:
2～4 parts of leaf, 1～3 part of the apple peel behind the extraction polyphenolic substance;
Said tonality material is the industrial residue that contains starchy material, preferred A Wei mycin fermentation residue or gibberellin fermented waste residue;
The parts by weight of tonality material are 5～65 parts, and high reactivity BHA is 10～75 parts;
(3) work in-process that step (2) is obtained mix with membrane-forming agent, spray the place that covers in needs, can form the completely degradable water retaining mulching of fruit residue humic acid of 0.12-0.38mm naturally;
It is a kind of in 0.2-10mg/L polyvinyl alcohol, chitose or the xylo-oligosaccharide that said membrane-forming agent is selected from concentration;
The adding weight of membrane-forming agent is said half-finished 0.001～0.009 times.
By the BHA-high reactivity completely degradable water retaining mulch film that production method of the present invention obtains, can prevent and treat effectively that cucumber downy mildew, Ipomoea batatas black spot, cotton are withered, the anthrax of verticillium, capsicum, tobacco etc.; And can effectively promote seed germination, fruit maturation, improve effects such as plant stress-resistance; And production cost is low, and the insulation volume increase can preserve soil moisture.Below describe enforcement of the present invention in detail by specific embodiment, purpose is to help the reader to understand the essence of an invention content better, but not as to the qualification of the scope of the present invention.
