Abstract
The water saving and maintaining composite liquid mulching consists of lignin, chitosan, collagen, surfactant, foaming agent, etc. and is sprayed to soil to form one layer of infiltrative mulching to cover soil surface. The mulching has the effect of preserving soil moisture via preventing evaporation of water and matching with water absorbing material. The mulching can be pushed by plant seedling to break and after some time, the mulching will degrade automatically to become humic acid capable of improving aggregate structure of soil.
Description
A kind of is main raw material with xylogen (the industrial waste xylogen is also available), produces the special technology of water saving, moisture-holding composite liquid mulching film, belongs to capital goods in the agricultural sector and makes the field.
The geographic soil of NORTHWEST CHINA desertifies and is on the rise, and the sandstorm that causes thus is also more and more fiery, and the lack of water short of rain of northern area is also brought many problems to Agricultural Development and ecological balance.The most effectual way that overcomes the above problems remains afforestation, plants grass or plants other farm crop.But for a long time, because lack of water, though afforestation, plant grass or the like, do, institute's kind of plant is many all is unable to sustain just branch death of lifetime, produces little effect every year.Therefore how the plant to the lifetime provides essential moisture content, is exactly that many scientific workers are concerned about and the target of research.Prior art mainly contains: drip irrigation type; Add the agent of taking precautions against drought in the soil; The packed method of plastics film.Drip irrigation type promptly provides essential moisture content with the droplet mode to plant, but this method, owing to need to install crisscross pipeline and available at any time water source, for large-area Arid lands, obviously be unpractical, say nothing of to administer in this way and desertified.The what is called agent method of taking precautions against drought is in soil, adds some macromolecule water absorbent materials and mixing with soil, and pelletizing forming, use mechanical or manual method, evenly shed in the field, and then sprinkle water to the field, water is absorbed by water-absorbing material, like this, and in a long time, a shape thing of making by water-absorbing material and soil, slowly provide moisture content to plant, external research in this respect is more, also early.This method is when regularly sprinkling water to the field, and effect is better.But when extraneous moisture supply was untimely, because the water-retaining capacity of water-absorbing material greater than the water-retaining capacity of plant, can cause plant death equally, this method cost was very high, also is the reason that is difficult to generally promote the use of.The packed method of plastic film, this method are used on the Nursery stock transplanting more at home, can prevent seepage, the evaporation of moisture to a certain extent, but the dish knot that can cause root system of plant, since plastics can not be in the soil natural degradation, cause secondary pollution for soil and environment, consequence is serious.
Purpose of the present invention provides a kind of composite liquid mulching film of water conservation and moisture-holding, and this mulch film is after spray method is sprayed at the field, form film at soil surface, the soil moisture conservation effect is arranged, not only prevented the evaporation of moisture effectively, and imitatively hinder the seedling of plant to pass rete.This mulch film has degradability, becomes the high-quality fertilizer material after the degraded, can suppress growth of pathogenic bacteria and breeding in the soil for crop absorption ， And.
Technical scheme Shi This sample of the present invention is realized, with main industrial chemicals xylogen, after process alkalinisation treatment And adds a spot of linking agent, with liquid by chitosan, collagen protein synthesis, mix by a certain percentage, and then add tensio-active agent and whipping agent, just can use behind the thorough mixing.Can directly be sprayed onto soil surface with spray method during use, also can be by other carrier, as the shaping bag of paper, staving, coated papers film etc.
Below in conjunction with embodiment, the detail explanation.
Embodiment 1, membrane-forming agent prescription (by weight percentage): 90% lignin liquor, (wherein containing 2% linking agent formaldehyde), 3% chitosan, 6% collagen protein respectively accounts for, 0.5% tensio-active agent, whipping agent is made liquid mixture, storage and is ensconced in the jar special.
The xylogen that adopts in the which can be industrial waste, ie the waste liquid of paper mill discharging and extract furfural with corn cob after, as the xylogen (ultra-fine grain) of waste material.Xylogen is very big at the nature amount, always with the fiber association.What we needed is the xylogen of separating from plant materials.The structural unit of xylogen is a phenylpropyl alcohol alkane, has methoxyl group on the phenyl ring and exists, and complicated functional group is arranged simultaneously, as hydroxyl, carbonyl, carboxyl, methyl etc.Because xylogen is a kind of natural high moleculer eompound of solubility, as long as the inclined to one side slightly alkali of solution gets final product film forming.In solution, add a certain amount of formaldehyde as linking agent , the xylogen relative molecular mass is increased, just can increase its intensity and film-forming properties, the formed film of xylogen has from Degradation, degradation product has the very sterilizing ability of Strong, can improve the resistance against diseases of farm crop.Chitosan is the product of chitin N-deacetylation, and chitosan exists in a large number at nature, mainly is distributed in arthropods such as shrimp crab, mollusk, annelid, Qiang Intestinal animal, marine alga etc.Here we will utilize the abundant oceanic resources of Hai Nan Island to extract the poly-chaff of shell.Chitosan has good film-forming properties.Film forming has good chemistry, and physical stability, performance are better than the plain film of acetic acid fiber, fabulous wetting ability is arranged, and permeation flux Da, And has biocompatibility, have biological degradability equally, its degradation product can improve micro-ecological environment, And and have antibiotic, preservative activity in soil.Collagen protein is proteic a kind of, is to give birth to gelatigenous material, and collagen is the maximum albumen of Mammals in-vivo content, and its structure is the structural protein of extracellular matrix.Behind chitosan and the collagen protein synthesis, can form polyamphoteric electrolyte, thereby have good film-forming properties, become film toughness.With the liquid of chitosan and collagen protein synthesis, after lignin liquid is mixed by weight percentage, will make film forming have better Strong degree, and wetting property, soil moisture conservation, water-retentivity, pungency and ventilation property.And have from broken property (be seedling when growing, can own bursting rete), better degradation property.For film forming cover ratio easy to use and raising soil, in above mixing liquid, add a spot of tensio-active agent and whipping agent storage and ensconce in the special-purpose filling standby again.During use, available spray method is sprayed at soil surface with mixing liquid, forms the layer of even foam, behind the froth breaking, just forms the layer of even mulch film at soil surface, because it has good wetting property, therefore all soil surfaces can be covered the last layer film.After after a while, can be degraded to humic acid fertilizer voluntarily, and can improve the crumb structure of soil.Chitosan and collagen protein be with before essential cellulose solution mixes, and both at first be mixed syntheticly, could mix with lignin liquor then....
If the present invention uses with the water-absorbing material collocation, can obtain better water conservation effect in arid, arid area.
Implement 2, the membrane-forming agent prescription is with embodiment 1.Its mixed liquid membrane-forming agent spraying is multiple on carriers such as paper, then,, be shaped to various bag shapes on request with film forming paper, barrel-shaped, coated papers etc. cooperate existing implanting and cultivating technology again, just can form various water savings, water conservation product.
Claims (4)
