Definitions

  • 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
  • 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.
  • the organic (acid) potash produced by the applicant of the present application is also a foliar fertilizer (see Chinese invention patent number).
  • 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.
  • 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.
  • organic potassium fertilizer containing urea which has the following chemical structure formula of organic potassium fertilizer
  • 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 theoretical basis of the invention :
  • 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
  • the commercial organic potassium fertilizer already contains 60% of the solute.
  • 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.
  • 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.
  • 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.
  • the urea-containing organic (acid) potassium fertilizer of the present invention has two ways in the preparation of the product; one way is to maintain the commercial brand of the organic potassium fertilizer obtained by the patent number ZL96118644. 5, that is, in the company's existing above 0 ⁇ 10 ⁇
  • the product is analyzed, when the product K 2 0% -18. 5-20. 0, add 1. 0-10.
  • the second way is to continue to add urea on the basis of adding 1-10% urea in the first way, so that the weight of urea reaches 37.5%, and finally the nitrogen content of the product is greatly increased, and the urea content is up to 27 3%, the nitrogen nutrient content of the fertilizer increased from 4.18% to 12. 55%, the potassium oxide content decreased slightly; while the total nutrient content increased, the applicant prepared the product of the second route as a product separately. , declare new product brands.

Abstract

La présente invention concerne un engrais potassique organique comprenant un sel de potassium organique et de l'urée. Le sel de potassium organique est représenté par la formule développée R-COOK, dans laquelle R désigne au moins un groupe CH3- CH3CH2- CH3COCH2CH2- CH3CHNH2- ou HOOCCH2CH2- et K un atome de potassium. Le rapport du sel de potassium organique à l'urée est de 100:(1-37.5). Cet engrais contient un acide organique et un élément nutritif inorganique à base de potassium et d'azote, la teneur en urée pouvant atteindre 27,3 %, alors que la teneur en azote augmente de 12, 56 %. L'invention concerne également un nouvel engrais composé organique liquide répondant aux besoins en terme de nutrition des cultures.
