Abstract
The invention discloses a boron-potassium binary foliar fertilizer which consists of the following raw material components in a molar ratio of 2:3 of boracic acid and potassium carbonate. The boracic acid reacts with the potassium carbonate for 30 to 60 minutes under normal pressure at a temperature of 65 to 80 DEG C and a reaction product is used as the boron-potassium binary foliar fertilizer. The boron-potassium binary foliar fertilizer has the advantages of simultaneously providing potassium and boron nutritions for crops, promoting mutual adsorption of the potassium and boron nutritions, improving the utilizing efficiency, obviously promoting the growing development of the crops and improving output and quality of the crops.
Description
Technical field
The present invention relates to a kind of binary foliar fertilizer, particularly relate to a kind of boron potassium binary foliar fertilizer.
Background technology
The potassium element is one of essential macroelement of crop growth, only time nitrogen, plain higher than phosphorus.The boron element is one of essential trace element of crop growth, can improve the yield and quality of crop.Many crops, the particularly crop such as Cruciferae, pulse family are had relatively high expectations to potassium element and boron element the time, and shortage can have a strong impact on grows and blossom and bear fruit.Show not only potassium deficiency, but also the multiple nutrient deficiency phenomenon such as boron deficiency in the many Soils In The Regions of China; In addition in recent years, the amount of application of nitrogen phosphorus fertilizer increases year by year, the relative minimizing of fertilizer, and the multiple nutrient deficiency phenomenon of potassium deficiency boron deficiency is day by day serious, and becoming affects the limiting factor that crop yield improves.Therefore targetedly use in macroelement and some, trace element can effectively improve output and improve quality.
Summary of the invention
The object of the invention is: a kind of boron potassium binary foliar fertilizer is provided, utilize potassium element and boron element to have the advantages that to mutually promote and absorb, promote boron potassium to absorb and utilising efficiency, improve potassium element and boron element to the promoter action of crop growth, satisfy crop growth required, strengthen economic benefit.
Technical solution of the present invention is: by boric acid H
3BO
3With salt of wormwood K
2CO
3With molar concentration rate 2:3, at normal pressure, temperature 65-80 ℃ reaction 30-60min, its reaction product is as boron potassium binary foliar fertilizer.
Wherein, in boron potassium binary foliar fertilizer, the content of boron with B count 1.5%, the content of potassium counts 16.0% with K.
Wherein, in boron potassium binary foliar fertilizer, boric acid and salt of wormwood react in the aqueous solution, and reaction product is boron potassium binary foliar fertilizer, and the formulation of fertilizer is aqua; The preparation method is: add in the water of 1 liter by the boric acid of molecular weight 97.6g with by the salt of wormwood of molecular weight 331.2g, at normal pressure, temperature 65-80 ℃ reaction 30min, its reaction product is boron potassium binary foliar fertilizer.
The invention has the advantages that boron potassium binary foliar fertilizer simultaneously for crop provides potassium element and boron element, the absorption of mutually promoting improves utilising efficiency, promotes crop yield and quality.
Embodiment
Below in conjunction with specific embodiment, technical solution of the present invention is described in further detail.Should be understood that these embodiment just in order to demonstrate the invention, but not limit the scope of the invention by any way.
Embodiment 1: add in the water of 2 liters by the 195.2g boric acid of molecular weight with by the 662.4g salt of wormwood of molecular weight, at normal pressure, 65 ℃ of reaction 30min of temperature, question response finishes after cooling to get aqua, is boron potassium binary foliar fertilizer.
Embodiment 2: add in the water of 5 liters by the 488.0g boric acid of molecular weight with by the 1656.0g salt of wormwood of molecular weight, at normal pressure, temperature 70 C reaction 30min, question response finishes after cooling to get aqua, is boron potassium binary foliar fertilizer.
Embodiment 3: add in the water of 10 liters by the 976.0g boric acid of molecular weight with by the 3312.0g salt of wormwood of molecular weight, at normal pressure, 80 ℃ of reaction 3min of temperature, question response finishes after cooling to get aqua, is boron potassium binary foliar fertilizer.
Boron potassium binary foliar fertilizer of the present invention application test in crop
For trying fertilizer: boron potassium binary foliar fertilizer of the present invention, boron content 1.5%, potassium content 16.0%.
Wheat breed: Common Wheat Varieties Huaihe River wheat 19.
Rape variety: Shi Lifeng.
Test method: respectively with wheat and Semen Brassicae campestris with 1.0% clorox sterilization 30min after with deionized water rinsing repeatedly, soak after 24h at 25 ℃ of lower vernalization 2d; Then selecting seed of the same size, cultivate in phytotron, 12h/12h round the clock, temperature is 26 ℃/20 ℃, illumination 65klx, relative humidity 70%, the full Hoagland nutritive medium that toos many or too much for use (not boracic and potassium) is cultivated; When wheat and Brassica Napus Seedling grow to 2 leaf 1 heart, blade spraying boron potassium binary foliar fertilizer, concentration dilution 250 and 500 times, namely distinguish boracic 60mg/Kg, potassium 640mg/Kg and boron 30mg/Kg, potassium 320mg/Kg, boric acid boracic 30mg/Kg, Repone K contains potassium 320mg/Kg, and contrast spray clear water repeats 3 times; Process and to measure that the seedling root is long after 7d, the bright dry weight of root, overground part height, the bright dry weight of overground part.
Test-results: boron potassium binary foliar fertilizer is processed as shown in table 1 on the impact of wheat seedling growth, and boron potassium binary foliar fertilizer is processed as shown in table 2 on the impact of seedling growth of rice.
Table 1 boron potassium binary foliar fertilizer is processed the impact on wheat seedling growth
Table 2 boron potassium binary foliar fertilizer is processed the impact on seedling growth of rice
Can find out from upper table seedling and spray the growing of seedling that boron potassium binary fertilizer can be conducive to promote wheat and rape.
