技术领域 Technical field
本发明属于肥料的生产与制备技术领域, 涉及一种含有尿素的有机 (酸)钾肥。 背景技术  The invention belongs to the technical field of production and preparation of fertilizers, and relates to an organic (acid) potassium fertilizer containing urea. Background technique
叶面肥是近年来发展的一种新型的肥料, 特别是作物追肥效果比单 独使用钾肥更好。 有机酸不仅是氮同化的受体, 也能调节作物的生理功 能, 钾可以促进光合作用, 两者结合效果更好。 例如, 本申请的申请人 生产的有机 (酸) 钾肥也是一种叶面肥, (参见中国发明专利号 Foliar fertilizer is a new type of fertilizer developed in recent years, especially the effect of crop topdressing is better than the use of potassium alone. Organic acids are not only receptors for nitrogen assimilation, but also regulate the physiological functions of crops. Potassium can promote photosynthesis, and the combination of the two is better. For example, the organic (acid) potash produced by the applicant of the present application is also a foliar fertilizer (see Chinese invention patent number).

OK 式中 R为 CH厂, CH3CH2-, CH3C0CHzCH2-, CH3CHNH2-, H00CCH2CH2-中的 至少一种, K为钾。该专利产品已进行生产、成为商品。该产品自从 1996 年投放市场以来, 以其具有肥效高、 易吸收、 用量少、 费用低、 增产幅 度明显, 并且无毒、 无害、 无残留等特点, 已经成为生产 "绿色食品" 的肥料品牌, 深受广大农民的欢迎。 但是作为叶面肥, 专利号 ZL96118644. 5的有机钾肥美中不足的是有机(酸)钾肥中并不含有氮元 素, 如果能将尿素添加至上述有机(酸)钾肥中, 更好的发挥有机酸同 化氮的作用, 使肥料中的氮、 钾和有机酸发挥协同效应, 其效果会更显 著。 目前尚未发现这方面的相关报道。 In the formula, R is at least one of CH plant, CH 3 CH 2 -, CH 3 C0CH z CH 2 -, CH 3 CHNH 2 -, H00CCH 2 CH 2 -, and K is potassium. This patented product has been produced and become a commodity. Since its launch in 1996, the product has become a fertilizer for the production of "green food" because of its high fertilizer efficiency, easy absorption, low dosage, low cost, obvious increase in yield, and non-toxic, harmless and residue-free. The brand is very popular among farmers. However, as a foliar fertilizer, the organic potassium fertilizer of Patent No. ZL96118644. 5 is lacking in organic (acid) potassium fertilizer and does not contain nitrogen. If urea can be added to the above organic (acid) potassium fertilizer, the organic acid assimilation can be better played. The effect of nitrogen makes the synergistic effect of nitrogen, potassium and organic acids in the fertilizer, and the effect will be more significant. No relevant reports have been found in this regard.
发明内容 本发明的目的在于, 提供一种含有尿素的有机钾肥, 制得的该有机 钾肥不仅含有机酸, 还含有钾、 氮无机营养, 是一秤新的液体有机复混 肥品种。 Summary of the invention The object of the present invention is to provide an organic potassium fertilizer containing urea. The organic potassium fertilizer obtained not only contains organic acid, but also contains potassium and nitrogen inorganic nutrients, and is a new type of liquid organic compound fertilizer.

OK 式中 R为 CH3— , CH3CH2-, CH3C0CH2CH2-, CH3CHNH2- , HOOCCH2CH2-中的 至少一种, -. K为钾, 其中: 还含有如下重量比例的尿素: 即有机钟肥: 尿素 = 100: ( 1 ~ 37. 5 )。 具体而言, 本发明得到的一种含有尿素的有机钾肥, 是在专利号 96118644. 5有机钾肥中添加尿素, 其重量比为: 有机钾肥: 尿素 = 100: ( 1 - 37. 5 λ In the formula, R is at least one of CH 3 — , CH 3 CH 2 —, CH 3 C0CH 2 CH 2 —, CH 3 CHNH 2 — , HOOCCH 2 CH 2 —, and K is potassium, wherein: Urea in the following weight ratio: organic clock fertilizer: urea = 100: (1 ~ 37. 5). Specifically, the organic potassium fertilizer containing urea obtained by the invention is added with urea in the organic potassium fertilizer of Patent No. 96118644. The weight ratio thereof is: organic potassium fertilizer: urea = 100: (1 - 37. 5 λ
上述含有尿素的有机钾肥具体的制备方法是, 在以专利号 ZL96118644. 5生产的有机液体钾肥中常温(20 °C ) 下加入尿素, 其重量 比为: 有机 4甲肥: 尿素 = 100: ( 1 - 37. 5 ), 而后搅拌, 使尿素充分溶解 到有机钾肥中即成。 本发明的理论基础:  The specific preparation method of the above organic potassium fertilizer containing urea is to add urea at room temperature (20 ° C) in the organic liquid potassium fertilizer produced by the patent No. ZL96118644. The weight ratio of the compound is: organic 4 fertilizer: urea = 100: ( 1 - 37. 5 ), and then stir, so that the urea is fully dissolved in the organic potassium fertilizer. The theoretical basis of the invention:
尿素在常温 20 °C下水中的溶解度为 105g/100g, 在商品有机钟肥中 溶解度已经达到 37. 5g/100g, 而商品有机钾肥中已经含有 60%的溶质。 显而易见, 这是一种非常有意义的发现。 经申请人的实验证明, 尿素在 液体有机钾肥中溶解性非常好, 有机酸和氮在钾元素的协调下, 同化作 用更加显著, 使肥料的应用价值更高, 本发明将有机(酸)钾肥中加入 一定量的尿素, 使其成为添加尿素的有机(酸)钾肥。 制得的肥料中不 仅含有机酸, 还含有钾、 氮无机营养, 是一种新的液体有机复混肥品种。 The solubility of urea in water at a normal temperature of 20 ° C is 105 g / 100 g, the solubility in commercial organic clock fertilizer has reached 37. 5g / 100g, and the commercial organic potassium fertilizer already contains 60% of the solute. Obviously, this is a very meaningful discovery. Applicant's experiments prove that urea is very soluble in liquid organic potassium fertilizer, and organic acid and nitrogen are assimilated under the coordination of potassium. The use of the fertilizer is more significant, and the application value of the fertilizer is higher. The present invention adds a certain amount of urea to the organic (acid) potassium fertilizer to make it an organic (acid) potassium fertilizer with urea added. The prepared fertilizer contains not only organic acid, but also potassium and nitrogen inorganic nutrients. It is a new liquid organic compound fertilizer.
而且尿素作为叶面肥是氮肥最好的一种, 极易被作物吸收。 尿素的 水溶性极好,在申请人的液体有机钾肥中添加 1-37. 5%的尿素, 当尿素添 加的重量与液体有机钾肥的比例达到 37. 5%时,添加后得到的液体有机复 混肥中尿素含量可达 27. 3%, 氮营养含量增加 0. 46%- 12. 55%, 氧化钾含 量由 18, 0%减少到 17. 82-13. 09%; 鉴于产品中营养成分(氮和氧化钾) 的总量相对增加, 更适合作物对多种营养的需要。 具体实施方式  Moreover, urea as the foliar fertilizer is the best kind of nitrogen fertilizer, and it is easily absorbed by crops. The water solubility of the urea is excellent. In the liquid organic potassium fertilizer of the applicant, the addition of 1-37. 5% of the urea, when the ratio of the weight of the urea added to the liquid organic potassium fertilizer reaches 37.5%, the liquid organic compound obtained after the addition The content of urea in the mixed fertilizer is up to 27.3%, the nitrogen content is increased by 0.46% to 12.5%, and the content of potassium oxide is reduced from 18, 0% to 17.82-13. 09%; The relative increase in the total amount of (nitrogen and potassium oxide) is more suitable for crops for multiple nutrient needs.
