In order to solve white pollution, currently testing a kind of humic acid multifunctional degradable mulch film.
What is the humic acid multifunctional degradable liquid-state mulch film?
So-called humic acid multifunctional degradable liquid-state mulch film is meant that with petroleum pitch or residual oil be raw material, perhaps with the tangerine bar, or with the contour dense organic waste water of papermaking wastewater, wine brewing, molasses, starch and marine alga with brown coal or weathered coal modification, and add a kind of liquid state material that other additives and auxiliary material produce.This material is sprayed onto on the soil and forms the very thin chocolate polymolecular chemoproection film of one deck on its surface, with obturator of the bonding one-tenth of soil surface, stops the volatilization of soil moisture, but rainwater, agricultural chemicals, nutritive substance etc. are fully infiltrated.This material sprays 40-60 days natural degradations gradually through field low-temperature oxidation and action of microorganisms.Be degraded to humic-acid kind (fertilizer) in 2-3 month, turn over be pressed into soil after, be the fine soil improvement agent.Because this fluent meterial promptly has the effect that heats, preserves soil moisture, keeps a full stand of seedings of plastic film, also has stronger adhesive capacity, grogs can be coupled to the ideal coacervate, corruption is decomposed into humic acids, thoroughly solved plastic film to the pollution of soil and environment with increased the characteristics of farming that integrate simultaneously again through, fertilizer and plastic sheeting for farm use, with after turn over and be pressed into soil, can become soil improvement agent, therefore be called as the humic acid multifunctional degradable black liquid-state mulch film.

How is the effect of humic acid multifunctional degradable liquid-state mulch film?
Soil surface sprays humic acids can make soil improve 1-4 ℃ of temperature by liquid-state mulch film, and the evaporation inhibiting rate is 30%.The soil moisture content increase rate is greater than 20%, the soil weight reduces 6%-10%, water stability group material quantity in the soil (＞0.25mm) can increase more than 10%, the crop growth phase shifts to an earlier date 3-10 days, the saltiness of the 0-50cm soil body reduces about 50%, and the amount of increase in production of Different Crop is many more than 20%, uses simultaneous test and shows, that liquid-state mulch film has is significantly cold-resistant, the effect of heating and precocious effect of increasing production, and wheat, corn increase by 20% to be.Increasing both production and income such as potato class, vegetables are more than 25%.The ground temperature rise is gathered in the crops in advance, and to reach the purpose of increasing both production and income, for the low area of year-round average temperature, effect is particularly remarkable.Can also reduce simultaneously the loss of fertilizer and agricultural chemicals, especially for the area of heavy rainfull, advantage is then more outstanding.In addition, add little fertilizer and weeding and pest-killing agent that various farm crop produce to be needed, more help to improve crop yield.
Should the liquid mulch film effect of humic acids be sure.
Soil moisture, plant absorbing are about 30% as everybody knows, and 70% be evaporated, and the liquid mulch film evaporation of humic acids inhibiting rate 30% that is to say that 40% moisture evaporation is still arranged, reduce evaporation again? let us is looked at.
Nestle company research centre, develop a kind of product innovation that reduces plant moisture evaporation in the desert greatly, spray agent, the Preliminary experiment results of Agricultural Research Institute of Sultanate of Oman Bu Si university shows, this novel spray agent, can make soil moisture reduce evaporation 75%, make this farm crop water reduce half.
The effective ingredient of " this handkerchief star of silicon " is a silicon gas alkane, and a kind of final can absorption by sandy soil belongs to the nontoxic biological degradation compound.
Using method is: mixing with water, every square feet sprays one earlier, and every public affairs are inclined with 75-80 kilogram spray ground, cultivate spray once at every turn.
After the drying, can form one deck silicon at desert surface, as seemingly baby diaper---water can penetrate this waterproof layer, enter soil, do not evaporate under the high temperature yet, in fact moisture content is stored in dry surface layer, (can also weed a garden), the following concrete degree of depth of certain degree of depth is determined that by concentration the spray back rises to face of land 5-20 centimetre to water layer, eliminates salinity, prevent that dust storm is at face of land pinching dew, a kind ofly be used for indoor plant and potted plant, " this handkerchief star of silicon " can reduce 3/4ths to water substantially, to 6/7.
But vaporization prevention 75% has overcome the deficiency of humic acids mulch film, and still, why silicon Si Pali does not promote, raw material is rare, and price height, pH value are 13, according to marketing information, every mu of fund that will drop into more than 100 yuan that sale provides, this is concerning the peasant, and acceptability is restricted.
