多功能缓释尿素肥料及制备方法 Multifunctional slow-release urea fertilizer and preparation method

技术领域 FIELD

[0001] 本发明涉及氮素肥料,具体地说是一种多功能缓释尿素肥料及制备方法。 [0001] The present invention relates to a nitrogen fertilizer, in particular a versatile method for preparing slow-release fertilizers and urea. 背景技术 Background technique

[0002] 目前工业所生产和农业施用的普通尿素是速溶肥料,在水和土壤中溶解转化很快。 [0002] The current industrial production and agricultural administration is instant urea fertilizer, dissolved in water and soil transformed quickly. 普通尿素施入土壤后在土壤中的脲酶作用下很快转化为铵态氮,大量的铵态氮使土壤PH值迅速升高,氨挥发增加;在通气状况良好的土壤中,在土壤硝化细菌的作用下发生硝化作用,铵态氮在很短的时间内就转化为亚硝态氮和硝态氮,硝态氮在土壤中极易淋失, 亚硝态氮也会以氮的氧化物的形式呈气态损失,造成肥料氮的大量损失,从而降低了肥料氮的利用率。 Normal Urea Added to the soil under the action of urease in the soil rapidly converted to ammonium nitrogen, so that a large amount of ammonium nitrogen in soil PH value increases rapidly increased ammonia volatilization; good soil aeration, nitrifying bacteria in the soil nitrification takes place under the action of ammonium nitrogen in a very short time into nitrate and nitrite nitrogen, nitrate leaching in soils easily, nitrite nitrogen oxides will the gaseous form of loss, resulting in a significant loss of nitrogen fertilizer, thereby reducing the utilization of fertilizer nitrogen. 普通尿素肥料肥效期短,肥料氮素利用率低,尿素氮的总体利用率只有30〜 35% 12,氮素的淋失、挥发、地表径流等损失较多,肥料施入的经济效益较低,造成资源的巨大浪费和农业生产成本的增加,同时产生地下水和土壤面源的污染,引起温室气体效应和水体的富营养化,使生态环境恶化。 Short fertilizer of urea fertilizer, nitrogen fertilizer use more low overall utilization of urea nitrogen only 12 30~ 35%, nitrogen leaching, volatilization, and other runoff loss, low fertilizer is the economic , resulting in a huge waste of resources and increase agricultural production costs, while producing soil and groundwater pollution point source, causing the greenhouse effect and eutrophication of water bodies, the deterioration of the ecological environment. 普通尿素的大量施用使农产品品质下降。 Large number of application of urea decreased the quality of agricultural products. 为减轻和解决这些问题,在提高农业生产经营技术管理的同时,需通过改进尿素肥料的自身性能,健全或完善尿素肥料的使用性能,延长肥料的有效作用时间,减缓其在土壤中的转化强度,促进作物对肥料的有效吸收,从而提高尿素氮肥的利用率。 To mitigate and solve these problems, while improving production and management technology management in agriculture, the need by improving urea fertilizer own performance, improve or perfect performance of urea fertilizer, extend the effective duration of action fertilizer and slow down the transformation strength in the soil , absorption efficiency of fertilizer to plants, thus improving the utilization of urea nitrogen.

[0003] 现有技术显示,在常温下,尿素(酰胺态氮)在脲酶的作用下首先转化为铵态氮, 进而转化为硝态氮,硝态氮很快被淋失或呈气态损失,而脲酶抑制剂可以有效抑制尿素向铵态氮的转化速度,延长酰胺态氮在土壤中的存留时间,增加尿素的有效作用时间;硝化抑制剂可以有效抑制铵态氮转化为亚硝态氮和硝态氮,延长铵态氮在土壤中的存留时间,增加氮肥的有效期,增效剂聚天门冬氨酸(多肽,Polyaspartic acid PASP)或其盐是一种肥料高效增效剂和新型植物营养吸收促进剂和调节剂。 [0003] In the prior art show, at room temperature, urea (an amide nitrogen) under the action of urease is first converted to ammonium nitrogen, and then converted to nitrate, nitrate leaching quickly gaseous or loss, the urease inhibitor can effectively inhibit the rate of conversion of urea to ammonium nitrogen, amide nitrogen extended residence time in the soil, increasing the effective duration of action urea; nitrification inhibitor can effectively inhibit the conversion of ammonium nitrogen to nitrite nitrogen and nitrate, ammonium extended residence time in the soil, to increase the validity of nitrogen, synergist polyaspartic acid (polypeptide, polyaspartic acid PASP) or a salt thereof is an effective synergist fertilizer plant nutrition and new absorption accelerators and modulators. 对植物所需营养成分具有极强的鳌合功能,能有效富集土壤中氮、磷、钾及微量元素供植物吸收利用,尤其是对锌、铁、锰三种元素的吸收和富集植物根部周围土壤中有用的元素,效果最为明显,具有长链蛋白和阴离子表面活性剂等优点,促进植物对营养元素的吸收,促进根系的生长,健壮植株,增强抗逆性, 改善品质,可作为良好的植物养分促进剂、助长剂、浸种剂、叶面肥、水分保持剂,且有不含激素、无毒、用过无残留等特点;PASP或其盐不同于植物激素,具有用量小、高抗病毒等特点ο Plant nutrients is highly desired chelating function, can effectively enrich soil nitrogen, phosphorus, potassium and trace elements for the utilization of plants, in particular the absorption of zinc, iron, manganese and three elements hyperaccumulators the soil around the roots of useful elements, the most obvious effect, having a long-chain protein and an anionic surface active agent advantages, promote plant absorption of nutrients to promote the growth of strong root system, enhance the resistance, to improve quality, as good plant nutrient promoter, enhancer, seed soaking agent, fertilizer, water retention agent, and there is hormone-free, non-toxic, non-residue characteristics used; PASP different from plant hormones or a salt thereof, with a small amount, high anti-virus features ο

[0004] 将生化抑制剂(脲酶抑制剂、硝化抑制剂)与PASP或其盐通过高科技结合后制成肥料复合增效剂,可充分发挥脲酶抑制剂和硝化抑制剂抑制尿素态氮水解和转化的协同作用,以及PASP或其盐对作物养分吸收的和增强抗逆性的增效作用,可有效抑制尿素的水解和向硝态氮的转化,可有效延长尿素或酰胺态氮肥肥效期,改善作物对氮素的吸收利用效果,增加植株对氮素的吸收量,提高肥料的利用率,增加农产品中蛋白质、氨基酸和脂肪等营养物质的含量,同时活化土壤中的植物所需的中微量元素和增加作物所需的微量元素在土壤中的有效富集量,促进作物对其它营养元素的吸收。 [0004] The biochemical inhibitor (urease inhibitors, nitrification inhibitor) or a salt thereof with PASP fertilizer made by high-tech composite synergist after binding, can take advantage of urease inhibitor and nitrification inhibitors inhibit the hydrolysis of urea nitrogen and synergy transformation, or a salt thereof as well as synergies PASP on nutrient absorption and enhanced stress tolerance, effective to inhibit hydrolysis and conversion to urea nitrate, urea or amide can effectively extend the lifetime nitrogen fertilizer, improve the utilization of the effect of nitrogen absorbed by crops, plants to increase the absorption amount of nitrogen, to improve the utilization of fertilizer, agricultural increase the content of protein, fat and other amino acids and nutrients, while activating the desired trace soil plants elements and increase the effective amount of trace elements necessary for the enrichment plant in the soil and promote plant absorption of other nutrients.

[0005] 目前的尿素肥料种类很多,缓释尿素肥料也有很多种,即有添加增效剂、缓释剂的尿素,又有包膜的尿素,尽管这些尿素肥料在尿素氮的释放和水解、延长尿素肥效期方面都有一定的效果,但其养分和功能都十分単一,只能为植物提供氮素营养,促进作物对氮的吸收与利用,在一定程度上提高尿素氮素利用率。 [0005] Currently many kinds of urea fertilizers, slow-release urea fertilizer there are many, that is adding a synergist, a release agent is urea, but also coated urea, although the release and hydrolysis of urea fertilizer urea nitrogen, extension of urea fertilizer on certain aspects of effect, but its features are very nutrient and a radiolabeling, can only provide nitrogen for the plant nutrition, promote the absorption and utilization of nitrogen in crops, raise urea nitrogen use efficiency to some extent. 而缺乏ー种既能为植物提供氮素营养又能为植物提供多种必需营养元素,同时促进植物对其它营养元素吸收利用、具有促进根系的生长,健壮植株,显著增强抗病、抗旱、抗倒伏和促早熟作用的尿素产品。 Lack ー nitrogen species only provide nutrition to the plant but also for a variety of essential plant nutrients, while promoting absorption and utilization of other plant nutrients, growth, promoting plant root robust, significantly enhanced resistance to disease, resistance to drought, lodging and promote early action of the urea product.
