Problems solved by technology

[0005] As a by-product of boric acid production, boron-magnesium fertilizer plays an important role in the boron and magnesium fertilizer market, but because the nutrient content in boron-magnesium fertilizer is easy to lose with water, the fertilizer effect cannot last
In addition, the contents of boron and magnesium in boron and magnesium fertilizers are 0.2-0.5% and 8.0-10.0%, respectively, which are relatively high, while the contents of other nutrients are relatively low. In the case of general lack of trace elements in the soil, single application of boron and magnesium Fertilizer can not play a good role in fertilizer, can not play a significant effect of increasing production

Embodiment 1

[0026] Test material: a high-efficiency boron-magnesium fertilizer provided in this example, the high-efficiency boron-magnesium fertilizer includes the following weight components: boron-magnesium fertilizer 60wt%, polyethylene glycol 5wt% (relative molecular mass is 4000-8000), brassica 2wt% trilactone, 5wt% ammonium molybdate, 5wt% zinc sulfate, 20wt% calcium nitrate, 2wt% manganese sulfate, 5wt% monoammonium phosphate; this high-efficiency boron-magnesium fertilizer is used in conjunction with 15-15-15 compound fertilizer;

[0027] Test time: March 2015-October 2015;

[0028] Test location: Wangjiazhai, Dangyang, Hubei;

[0029] Test crops: citrus;

[0030] Test soil: red soil; (the basic physical and chemical properties of the test soil are: pH 5.32, organic matter 12.79g / kg, alkaline nitrogen 9.33mg / kg, available phosphorus 11.02mg / kg, available potassium 87.5mg / kg)

[0031] Experimental design: base application of 15-15-15 compound fertilizer 50kg / mu + high-efficiency...

Embodiment 2

[0035] It is substantially the same as Example 1, except that the high-efficiency boron-magnesium fertilizer includes the following weight components: boron-magnesium fertilizer 65wt%, polyethylene glycol 5wt%, amine fresh fat 2wt%, ammonium molybdate 3wt%, zinc sulfate 8wt%, calcium nitrate 15wt%, manganese sulfate 3wt%, monoammonium phosphate 3wt%; this high-efficiency boron-magnesium fertilizer is used in conjunction with 15-15-15 compound fertilizer.

Embodiment 3

[0037] Substantially the same as Example 1, the difference is that the high-efficiency boron-magnesium fertilizer includes the following weight components: boron-magnesium fertilizer 70wt%, polyethylene glycol 5wt%, sodium naphthalene acetate 2wt%, ammonium molybdate 2wt%, zinc sulfate 10wt%, calcium nitrate 10wt%, manganese sulfate 5wt%, monoammonium phosphate 1wt%; this high-efficiency boron-magnesium fertilizer is used in conjunction with 15-15-15 compound fertilizer.

[0038] The preparation method of the efficient boron-magnesium fertilizer of present embodiment 1-3 is as follows:

[0039] Step S1: Grind boron-magnesium ore into 200-mesh fine powder, add sulfuric acid at a ratio of 1:5 between mineral powder and acid, and react for 2-5 hours. Cool in a constant temperature tank, crystallize boric acid crystals at 0-20°C, carry out solid-liquid separation, and then carry out second crystallization at 10-30°C to obtain boron-magnesium fertilizer.

[0040] Step S2: Mix boro...

Abstract

The invention discloses high-efficiency boron-magnesium fertilizer and a preparation method thereof. The high-efficiency boron-magnesium fertilizer is prepared from the following components by weight percent: 60 to 70 percent of boron-magnesium fertilizer, 1 to 5 percent of polyethylene glycol, 1 to 2 percent of plant growth regulators, 2 to 5 percent of ammonium molybdate, 5 to 10 percent of zinc sulfate, 10 to 20 percent of calcium nitrate, 2 to 5 percent of manganese sulfate and 1 to 5 percent of monoammonium phosphate. The high-efficiency boron-magnesium fertilizer belongs to the field of agricultural fertilizer, and is mainly used for southern soil lack of trace elements; and the high-efficiency boron-magnesium fertilizer can effectively improve the nutrition of the soil, improve the lasting effect of the boron-magnesium fertilizer and increase the yield and fruit settling rate of crops.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a high-efficiency boron-magnesium fertilizer and a preparation method thereof. Background technique [0002] The recent national soil census statistics show that the arable area of ​​boron-deficient elements in the country is more than 500 million mu, especially in the southern region, where the proportion of boron-deficient arable land is greater than 60%. [0003] In the late 1980s, rapeseed "flowers but not fruit", cotton "buds but not flowers", wheat "sickness" and fruit trees "shrinkage" appeared in some areas of my country. Many experiments and studies have found that these physiological diseases are closely related to soil boron deficiency. [0004] At present, the boron content in some soils in our country is lower than the critical value of soil boron deficiency, so the development of boron fertilizer resources and the application of boron fertilizer to soil are ...
