Description
Technical field
The present invention relates to chemical technology field, particularly relate to a kind of compound method of fertilizer special for banana.
Background technology
Banana flavor is fragrant, nutritious, can gather in the crops all the year round, also be paid attention to very much in Temperate Region in China.China is one of ancient country of cultivating banana in the world, and the banana variety of external main cultivation is mostly passed by China and goes.Banana is distributed in the tropical and subtropical region within east, west, 30 °, north and south, the Southern Hemisphere latitude.China Banana is mainly distributed in Guangdong, Guangxi, Fujian, Taiwan, Yunnan and Hainan, and also there is a small amount of cultivation in Guizhou, Sichuan, Chongqing.Banana belongs to high calorie fruit, reaches 91 kilocalories according to the thermal value analyzing every 100 grams of pulp.At some torrid areas bananas also as main food.Banana pulp nutritive value is quite high, every 100 grams of pulp carbohydrate containing 20 grams, 1.2 grams, protein, 0.6 gram, fat; In addition, also containing various trace elements and VITAMIN.Wherein vitamin A energy growth promoting effects, builds up one's resistance to disease, and is that the normal fecundity of maintenance and eyesight institute are required; VitB1 can anti-vitamin B1 deficiency, promotes appetite, aid digestion, neuroprotective system; Riboflavin can promote human normal g and D.Every 100 grams sugary more than 15% of banana pulp, acid 0.2 ~ 0.3%, protein 1.5%, also has abundant 53 milligrams, phosphorus, calcium 19 milligrams, 400 milligrams, potassium, Catergen 4 milligrams.Banana is also containing pectin, multiple enzyme material and trace element etc.
At present, to the fertilizer that banana is used, normally the mixing of phosphate fertilizer, potash fertilizer and grey excrement is used, this kind of fertile growth that can promote banana of mixing, but the content of the nitrogen in this kind of composite fertilizer, potassium, phosphoric does not meet the ratio needed for Banana Growth, be difficult to the demand meeting banana, if increase amount of application, other elements will be caused to waste, and pollution can be brought to environment.By at internet retrieval, the patent application about fertilizer special for banana has several, and such as, application number is " a kind of fertilizer special for banana " of 01128696.2, but the patent documentation do not seen about fertilizer special for banana compound method or report.
Potassium primary phosphate is that one can the field such as applicable industry, agricultural, and tool has been widely used.As in the production of industrial aspect mainly as chemical raw material, agriculturally be mainly used in the interpolation of feed and chemical fertilizer, in addition, potassium primary phosphate can also be used for food to be added as raw material, improve food mouthfeel and quality, supplement the trace elements such as potassium element for human body.Production method at present for potassium dihydrogen phosphate product mainly contains neutralisation, extraction process, ion exchange method, double decomposition, crystallization process and electrolytic process etc., the feature that neutralisation produces potassium primary phosphate neutralisation is that technical process is short, technology maturation, equipment is few, quality product is high, energy consumption is low, less investment.This method is with thermal phosphoric acid and potash for raw material, and production cost is high, is difficult to agriculturally applying, mainly for the production of the potassium primary phosphate of food, medicine and technical grade.Solvent extration becomes one of most effective means of purification of phosphoric acid, produces provide conveniently with phosphoric acid by wet process.Adopt organic solvent extractionprocess, optionally to extracting, can get rid of the type impurity ion in raw phosphoric acid, the potassium dihydrogen phosphate product quality produced is high, and energy consumption is low, but the phosphoric acid rate of recovery is low, and organic solvent is expensive, has pollution to environment.Ion hands over method can obtain compared with the raw material of pure phosphoric acid ammonium dihydrogen solution as ion-exchange with removing most of impurity with phosphoric acid by wet process in ammonia, simultaneously with the potassium hydroxide that more cheap Repone K replaces neutralisation used, production cost has larger decline compared with neutralisation, but the steam output of this method too major end item needs vaporize water, energy consumption is too high, and resin price is expensive, one-time investment is larger.In addition, often produce the ammonium chloride dilute solution that potassium primary phosphate wants by-product, when output is large, aftertreatment is pretty troublesome; React with Repone K the technical process generating potassium primary phosphate again after double decomposition mainly adopts phosphoric acid and sodium carbonate to react to prepare SODIUM PHOSPHATE, MONOBASIC.The feature of this method is that production unit is simple, and reaction conditions is gentle, easy to operate, does not pollute, reliable in quality, but the quality product of this method is not as neutralisation, can contain a small amount of sodium-chlor.Reclaim sodium-chlor power consumption in mother liquor after crystallization high, be worth low.
The improvement of above technology still also exists larger problems, its process regulation is bad, then can generate other other products in the reaction, potassium phosphate,monobasic is generated as potassium primary phosphate is easily hydrolyzed in water, cause the yield of potassium primary phosphate lower, meanwhile, in whole production technique, also have a large amount of waste and old mass emissions, be difficult to the zero release problem of address contamination; And, potassium dihydrogen phosphate product is also difficult to separate out completely in the process of crystallization, but be in the saturated solution of state of saturation all the time, then content is larger in the solution to make potassium primary phosphate, if degree of depth crystallization, the purity of the potassium dihydrogen phosphate product then obtained is poor, affects the quality of potassium dihydrogen phosphate product.Based on this, by carrying out research and discussion to potassium primary phosphate as the character of fertilizer, and in conjunction with a large amount of reports, potassium primary phosphate has the character that can be absorbed by plants and reach more than 98%, and it is reported that common phosphate fertilizer utilization ratio absorbed by crops only can reach 10 ~ 25%, common potash fertilizer only absorbed by cropsly can utilize 45 ~ 60%, and the nitrogenous fertilizer such as urea, carbon ammonium only absorbed by cropsly can utilize 20 ~ 46%; As can be seen here, potassium primary phosphate utilization ratio absorbed by crops is apparently higher than common azophoska.
There is the method for investigator's other chemical fertilizer of coproduction in the process preparing potassium primary phosphate, such as, if the patent No. is 200610048214.6 disclosed " co-productions of a kind of potassium primary phosphate, S-based compound fertilizer and polymerize aluminum chloride ", it is produced in potassium primary phosphate process and produces S-based compound fertilizer and polymerize aluminum chloride, what improve that phosphoric acid by wet process prepares impurity in potassium dihydrogen phosphate product process affects problem, improves economic benefit.But do not see having and anyly carry out element collocation about by composite fertilizer's preparation process for the demand of crop, and the technical scheme being made into the composite fertilizer of chemical combination state exists.In the process of preparation potassium dihydrogen phosphate product, the waste of a large amount of potassium primary phosphate that potassium primary phosphate crystallization not exclusively can cause, potassium primary phosphate crystallization can bring a large amount of impurity into potassium dihydrogen phosphate product excessively again, then makes the purity of potassium dihydrogen phosphate product lower.By retrieving on the net, there is no the patent documentation or report that solve this technical problem.
