Description
Facts have proved of modern agricultural development, sufficiently and reasonably utilizing chemical fertilizer is effective, the irreplaceable important channel that promotes crop yield, quickens agricultural development.Chemical fertilizer application has become the peasant and has produced material investment maximum in the investment, accounts for 50% of its full scale production investment.
The chemical fertilizer utilization ratio is generally lower in China's agriculture production, the utilization ratio of phosphate fertilizer in nitrogen, phosphorus, potassium three big key elements is minimum, particularly the utilization ratio of its this season crop only is about 10～28%, all the other phosphorus elements remain in the soil or are lost in the water surrounding, the not only serious waste and the tremendous economic loss of failing to be utilized effectively and causing the energy, resource because of a large amount of fertilizer, and make and receive the sewage body and cause eutrophication to cause the destruction of ecotope.Undoubtedly, phosphate fertilizer utilization efficiency is low is the one of the main reasons that works the mischief.
The phosphorus fertilizer is that the mineral wealth that rely on phosphorus are produced synthetic, is one of crop three big key elements that are only second to by nitrogenous fertilizer.Compare with rich phosphorus country, the phosphate rock resource of China is deficient relatively, therefore must pay attention to effective utilization of limited phosphate rock resource.China's soil lacks the phosphorus area and accounts for 74% of total area under cultivation, and high concentration phosphorus chemical fertilizer product mainly relies on import, a large amount of foreign exchanges of annual cost.Actual production shows that the raising crop yield is more and more higher to the dependency of phosphate fertilizer.But, in the agriculture production phosphate fertilizer utilization efficiency low be serious realistic problem, the residual soil of about 70% phosphate fertilizer, flow into environment, cause the fertilizer waste to bring serious financial loss and environmental destruction to form body eutrophication, this detrimentally affect is in rising trend.Therefore, study new fertilizer variety, increase operation rate, reduce loss of effective components, eliminating it is urgent problem to eco-environmental impact.
At present, domestic research about phosphate fertilizer utilization efficiency, focus mostly in phosphate fertilizer in soil form and transformation mechanism and utilization ratio not the plateau because of aspect the rationalization of research and fertilising, tillage method.The research that improves phosphate fertilizer validity and utilization ratio soil from the physicochemical property of fertilizer self, development and production aspect seldom.Therefore, the demand that the reasonable utilization of limited phosphate rock resource is still improved crop yield and preserving the ecological environment no matter, the research and development phosphate fertilizer variety that validity is strong in soil, the crop utilization rate is high is very necessary.
From fertilizer self, cause the low major cause of phosphate fertilizer utilization efficiency to be solvable phosphate fertilizer, after particularly high molten phosphate fertilizer such as diammonium phosphate, general calcium etc. are manured into soil, phosphate concentration is very high in solution around the fertilising point, material and active phosphorus acid ion reaction precipitations such as the iron in the soil constitution, aluminium, calcium, generate low molten and even insoluble phosphoric acid salt, make phosphorus reduce the validity of plant.In acid soil, phosphoric acid combines with metal oxide (as iron, aluminium, calcium etc.), generates tertiary iron phosphate, aluminum phosphate of gluey amorphous state etc.Through hydrolysis, aging, be transformed into the pink iron ore of crystalline state, variscite, hydroxyl phosphorus lime, further become and close poultry attitude phosphoric acid salt, more seriously lose the validity of phosphorus to plant, cause the low disastrous effect of phosphate fertilizer utilization efficiency.There are some researches show in recent years that the quick-acting phosphate fertilizer that apply were all permanent unfixing by soil, continuous administration can show after effect.But.The demonstration of this effect is still needed the time in 10～20 years, and it is about 30% that its utilization ratio is only brought up to, phosphate fertilizer effectively utilize aggregate level still very low, the fertilizer waste is still very serious.
Phosphate fertilizer is manured into soil, and meets bad climate such as precipitation and irrigation, and moving with water of generation is another low major reason of phosphate fertilizer utilization efficiency.Therefore destroy more and more heavylier and plant water ecological setting that loss causes, many body eutrophications are serious, and operability reduces, the situation aggravation of shortage of water resources, and worker, agriculture production and people life water are seriously influenced.The part agricultural product quality also accumulates reduction because of chemical fertilizer in environment, directly threaten human health.
But alkali lignin is a kind of self-sow resource thing.About 500,000,000 tons of the annual straw output of China.The content of alkali lignin in all kinds of straws is about 20%, can regenerate naturally every year about 100,000,000 tons.Annual about 4,000 ten thousand tons of the utilization of pulping and paper-making straw, xylogen wherein is less to be utilized, and majority drains into environment with pulp-making waste-water, has caused a large amount of wastings of resources and serious environmental destruction.If 50% of alkali lignin is recyclable amount in the paper grade (stock) straw, surplus in the of then annual recyclable 300 ten thousand tons.The a large amount of alkali lignins of paper-mill black liquor and development as resource process for producing are the reliable raw material sources of present method.The application of alkali lignin is effectively to utilize rural activity product, raising agriculture production benefit and the eucyclic positive behave of agricultural environment.
Characteristics of the present invention are to utilize the raw material production lignin phosphate fertilizers such as alkali lignin of black paper-making liquid of alkali pulping recovery, alkali lignin is as main raw material components according, use it to the source abundance, be easy to get and the synthetic synergist of phosphate of structural performance, realize increasing the validity of phosphate fertilizer in soil, improve utilization rate of fertilizer, reduce the environmental pollution that its loss causes.By being high molten phosphate fertilizer modification, high molten phosphate fertilizer solubleness is reduced, reduce the concentration of fertilising point phosphate radical, weaken the speed and the degree of soil constitution fixing phosphate radical.Introduce competitive adsorption, utilize hydroxyl, carbonyl, carboxyl and the reticulated structure thereof of alkali lignin molecule and produced chelating, complexing and the adsorption of organic acid the iron of fixing available phosphorus in the soil, aluminium, calcium etc. by soil microbial degradation, reduction is to the concentration of solvable phosphate radical toxic ion, the chemical precipitation that reduces the active phosphorus acid group is with fixing, improve the validity of soil phosphorus, reach and save the fertile multipurpose economic, social, environmental benefit that increases production, improves.
Alkali lignin is as the major advantage of phosphate fertilizer modified feedstock: (1). alkali lignin is a kind of self-sow resource, and development and application has competent source to ensure; (2). alkali lignin is the paniculate reticular polymer polymkeric substance of a kind of phenol type three-dimensional space, the various active group of structural unit such as carboxyl, hydroxyl, carbonyl etc., its high reaction activity and high and produced organic acid by soil microbial degradation, the iron of fixing active phosphorus in the soil, aluminium, calcium etc. are produced strong complexing, adsorption, can weaken active phosphorus by chemical precipitation and fixing, increase the validity of phosphorus in the soil; (3). alkali lignin makes soil produce crumb structure, is degraded by microorganisms in soil to soil ulmin plays soil improvement agent, promotes the soil water-stable granular structure to generate, and increases the gas exchange action of soil, improves soil water retention, protects fertile ability.Therefore, the combined effect that reaches with lignin modification, synergy of common phosphate fertilizer is that other materials can not be compared.
