Problems solved by technology

However, pentamethylenediamine is liquid at normal temperature and has a foul odor similar to ammonia; it is flammable, highly toxic, and highly irritating; after inhalation, it may cause spasm, inflammation, and edema of the larynx and bronchi, chemical pneumonia or pulmonary edema and lethal; severely limited the application of pentamethylenediamine in agriculture

Embodiment 1

[0029] Embodiment 1: the effect of pentamethylenediamine and pentamethylenediamine salt on plants:

[0030] In the blooming stage of greenhouse tomatoes, 1mM, 500μM, 50μM and 1μM dilute pentamethylenediamine solutions and pentamethylenediamine phosphate aqueous solutions were applied by foliar spraying, and the fruit setting rate of different concentrations of pentamethylenediamine was higher than that of the clean water control group. It can increase by 3% to 25%, and the fruit setting rate of applying different concentrations of pentamethylenediamine phosphate aqueous solution can increase by 6% to 27% compared with the clean water control group. The specific data are shown in Table 1. It can be seen that pentamethylenediamine and pentamethylenediamine salts can play a positive role in the improvement of fruit setting rate and yield. Addition in the form of salt can reduce or even avoid this problem.

Embodiment 2

[0036] Example 2: Potato implementation example:

[0037] Use 80kg of pentamethylenediamine acetate, 5kg of potassium dihydrogen phosphate, 15kg of potassium sulfate, 3kg of borax, and 3kg of EDTA-Mn as the main components, dissolve and mix with 1000kg of water and adjust the pH to between 5.5 and 6.5.

[0038] Sprayed as a foliar fertilizer at the full flowering stage of potatoes, compared with the blank group with the same amount of clear water, the yield per mu of potatoes increased by about 19% to 35%, while the comparison group without pentamethylenediamine salt but with the same other ingredients, compared with the same amount of clear water Compared with the blank group, the yield per mu of potatoes only increased by about 6% to 16%, see Table 3.

[0040]

Embodiment 3

[0041] Embodiment 3: the embodiment that is applied to greenhouse tomato:

[0042] Formula A: 40kg pentamethylenediamine phosphate, 15kg urea, 5kg manganese sulfate, 8kg langbeinite, 3kg of EDTA-Zn, 3kg of EDTA-Fe, 4kg of lysine, 0.5kg of Tween 80, dissolved in 1000kg of water After mixing, adjust the pH to between 5.8 and 7.0, and use it as a foliar fertilizer. Spray once at the full flowering stage of the greenhouse tomato and 2 weeks after the full flowering stage.

[0043] Compared with the blank control group sprayed with clear water after two periods of fertilization, the yield can be increased by 21% to 45%, while the control group sprayed with dilute pentamethylenediamine phosphate solution can increase the yield by 8% compared with the blank control group sprayed with clear water. %~18%, see Table 4.

[0044]Alternative formula B: 20kg pentamethylenediamine adipate, 50kg pentamethylenediamine phosphate, 5kg manganese sulfate, 5kg langbeinite, 4kg lysine, 2kg of EDTA...

Abstract

The invention discloses a compound foliar fertilizer containing a pentanediamine salt. The compound foliar fertilizer comprises the pentanediamine salt, a major element fertilizer and a medium-trace element fertilizer, wherein the pentanediamine salt includes, but not limited to, one or a combination of two or more of pentanediamine dicarboxylate, pentanediamine phosphate, pentanediamine acetate,pentanediamine adipate, pentanediamine borate and pentanediamine nitrate; the major element fertilizer includes, but not limited to, one or a combination of two or more of urea, potassium dihydrogen phosphate and potassium sulfate; and the medium-trace element fertilizer includes, but not limited to, one or a combination of two or more of ammonium molybdate, manganese sulfate, borax, boric acid, copper sulfate, leonite, EDTA-Zn, EDTA-Fe and EDTA-Ga. According to the compound foliar fertilizer, through converting pentanediamine into a pentanediamine salt, the defect that the pentanediamine is liquid at normal temperature, has an irritant odor and has certain toxicity is overcome; and the compound foliar fertilizer has the characteristics of environment-friendliness, flexibility in use, andthe like and has the advantages of increasing crop yield, improving tolerance of crops to stress, and the like.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a compound foliar fertilizer containing pentamethylenediamine salt. Background technique [0002] my country is a big country in the production and use of chemical fertilizers in the world, with an annual consumption of more than 50 million tons. Chemical fertilizers have made a huge contribution to improving crop yields in my country and the world. However, the long-term large-scale or excessive application of chemical fertilizers has brought about a series of problems, such as secondary salinization of soil, acidification, ammonia gas in farmland soil and greenhouse gas N 2 Due to the large amount of O emissions and the eutrophication of farmland water, we continue to seek new fertilizers to replace or partially replace chemical fertilizers. [0003] Pentamethylenediamine, the molecular formula is C 5 h 14 N 2 , as a kind of bio-based substance, generally obtained fr...
