Problems solved by technology

[0005] The above patent application is to add iron, zinc and trace elements to boron and magnesium fertilizers, without adding the three main fertilizers of nitrogen, phosphorus and potassium, so it can only be used as an auxiliary fertilizer for the main fertilizer, and its production increase effect is limited to a certain extent
[0006] At present, there is no report on the multi-element compound boron and magnesium fertilizer containing the three main fertilizers of nitrogen, phosphorus and potassium

Embodiment 1

[0022] Example 1 Manufacture of dehydrated boron-magnesium fertilizer: the by-product magnesium sulfate heptahydrate from boric acid production is crystallized, dehydrated by rotary flash evaporation, that is, coal is put into the stone masonry furnace and ignited, and the flue gas in the furnace enters the rotary room and is dried by a blower Inside the machine, the crystallization of the magnesium sulfate heptahydrate mixture is stirred in by the auger, and it is in direct contact with the flue gas for dehydration. The magnesium sulfate mixture monohydrate is separated from the cyclone separator to obtain the dehydrated boron magnesium fertilizer. The main component element content is: Mg 9%, S 13%, B 0.6%, Fe 0.3%.

[0023] Take 100kg of the above-mentioned dehydrated boron-magnesium fertilizer, 50kg of potassium sulfate, 50kg of ammonium phosphate, and 50kg of urea, and stir evenly in a mixing mixer to make a multi-element composite boron-magnesium fertilizer. The active in...

Embodiment 2

[0028] Example 2 Take 100kg of the above-mentioned dehydrated boron-magnesium fertilizer, 30kg of potassium chloride, 60kg of diammonium hydrogen phosphate, and 60kg of ammonium bicarbonate, and stir evenly in a mixing mixer to prepare a multi-element composite boron-magnesium fertilizer. The active ingredients of each element are w% : Mg 3.5, S 5.2, B 0.23, Fe 0.12, K 6.2, P 5.5, N 9.

[0029] Use the above-mentioned multi-element compound boron-magnesium fertilizer to carry out base fertilizer application in the soybean field, and the fertilization rate is 10kg / mu.

[0030] Observation during the crop growth period: good growth and strong stress resistance; fertilizer effect investigation: 100-grain weight 26g, yield 150kg per mu.

[0031] Under the same conditions, commercial potassium sulfate compound fertilizer was used as a control.

[0032] Observation during the crop growth period: good growth and good stress resistance; fertilizer effect investigation: 100-grain weig...

Embodiment 3

[0033] Example 3 Take 100kg of the above-mentioned dehydrated boron-magnesium fertilizer, 30kg of potassium nitrate, 50kg of potassium hydrogen phosphate, and 70kg of ammonium sulfate, and stir evenly in a mixing mixer to make a multi-element composite boron-magnesium fertilizer. The active ingredient w% of each element: Mg 4 , S 10.5, B 0.24, Fe 0.13, K 10.1, P 4.5, N 7.6.

[0034] Use the above-mentioned multi-element compound boron-magnesium fertilizer to carry out topdressing in the tillering stage of the paddy field, and the fertilization rate is 10kg / mu.

[0035] Observation during the crop growth period: good growth and strong stress resistance; fertilizer effect investigation: 100-grain weight 27g, yield 700kg per mu.

[0036] Under the same conditions, 20kg of commercial potassium sulfate compound fertilizer, 15kg of urea, and 15kg of diammonium phosphate were used as a control according to normal fertilization.

[0037] Observation during the crop growth period: goo...

Abstract

The invention relates to a multi element composit boron magnesium fertilizer as neutral and white particles, which contains 100 portions of dehydrated boron magnesium fertilizer, 30-50 portions of potassium fertilizer, 50-60 portions of phosphate fertilizer and 50-70 portions of nitrogen fertilizer. The invention uses heptahydrate magnesium sulfate as main boron magnesium fertilizer to be dehydrated into the boron magnesium fertilizer of magnesium sulfate, thereby improving effective components, reduce transportation cost and avoid caking, with simple application. The fertilizer contains three main elements as nitrogen, phosphate and potassium, medium and micro components as magnesium, sulfur, iron and boron, with abundant effective components, wide application, acceleration on crop growth and the function for improving the anti-disease and anti-pest ability of crop, maturing fruit early and improving yield.

Description

technical field [0001] The invention relates to an inorganic fertilizer, in particular to a boron-magnesium fertilizer. Background technique [0002] Boron-magnesium fertilizer has been used for many years and has achieved a certain effect of increasing production. However, since boron-magnesium fertilizer contains more than 70% magnesium sulfate heptahydrate, the active ingredient is low and the transportation cost is high. It is easy to lose crystal water, resulting in agglomeration, which is inconvenient to use. Boron and magnesium fertilizers have a single fertilizer effect, and can only be used alone in the red soil zone in the middle and lower reaches of the Yangtze River where there is a serious magnesium deficiency in my country. The scope of use is also limited by the area of ​​use and crop varieties. Handle difficulties and increase production. In order to improve fertilizer efficiency, it needs to be mixed with other elemental fertilizers, but the selection and u...
