Problems solved by technology

[0002] Some of the existing foliar fertilizers used for fruits and melons do not have the function of supplementing selenium, such as commercially available fresh fruit sweeteners, etc.; although some have the function of supplementing selenium, they are not suitable for all fruits and melons, such as commercially available Although the selenium treasure can supplement selenium for apples, it is easy to cause phytotoxicity when applied to citrus and other fruit trees; especially the general selenium-rich foliar fertilizers do not pay attention to the effects of sweetening, flower preservation, fruit preservation and fruit cracking prevention The content of trace elements such as boron, molybdenum, zinc etc. that has is too little, has influenced the yield per unit area of ​​fruit and melon; Selenium treasure, etc., its price is relatively high, and it is difficult for farmers to accept it

Embodiment 1

[0032] Embodiment 1 (unit: 10 grams, the same below)

[0033] The weight of each component or raw material is as follows (the purchased raw materials are powdery or crystalline):

[0034] Selenic acid 20, sodium nitrophenolate 10, rare earth 20, 2,4-D sodium salt 0.6, Pingpingjia 0.6, ammonium dimolybdate 12.5, zinc sulfate heptahydrate 12.5, borax 23.8.

[0035] In actual operation, the above raw materials are not weighed first, but whichever is used, such as sodium binitrophenolate, zinc sulfate heptahydrate, ammonium dimolybdate and 2,4 -D sodium salt. The weight unit is 10 grams, such as selenic acid 20 (10 grams), the actual weighing is 200 grams.

[0036] ① First, dry the raw materials to be used in the drying room (the so-called drying is generally based on common sense of life and hand feel, and it is mainly for the convenience of the next crushing process).

[0037] In a closed room with a dehumidifier and an air conditioner, that is, the humidity in the room does ...

Embodiment 2

[0045] The weight of each component, i.e. raw material, is as follows:

[0046] Sodium selenate 15, sodium nitrophenolate 6, anhydrous calcium chloride 35, 2,4-D sodium salt 0.5, Pingping 0.5, ammonium tetramolybdate 8.5, zinc sulfate monohydrate 22, boric acid 12.5.

[0047]The preparation method is the same as in Example 1 (only the specific raw materials and rare earths of selenate, molybdenum, zinc, boron have changes: sodium selenate replaces selenic acid, anhydrous calcium chloride replaces rare earth, ammonium tetramolybdate replaces ammonium dimolybdate , zinc sulfate monohydrate replaces zinc sulfate heptahydrate, and boric acid replaces borax), and the product appearance is also with embodiment 1.

Embodiment 3

[0049] The weight of each component, i.e. raw material, is as follows:

[0050] Sodium selenite 18, sodium nitrophenolate 8, rare earth 15, anhydrous calcium chloride 15, 2,4-D sodium salt 0.4, Pingping 0.4, ammonium heptamolybdate 10.2, zinc sulfate monohydrate 16.5, boric acid 16.5.

[0051] Preparation method is the same as embodiment 1 (only the concrete raw material of selenate, molybdenum, zinc, boron and the content of rare earth have change namely: sodium selenite replaces selenic acid, rare earth and anhydrous calcium chloride replace single rare earth, heptamolybdenum Ammonium acid replaces ammonium dimolybdate, zinc sulfate monohydrate replaces zinc sulfate heptahydrate, and boric acid replaces borax), and the product appearance is also with embodiment 1.

Abstract

The selenium-rich sweetener consists of selenate 10-20 wt%, sodium nitropeolate compound 5-10 wt%, RE and / or calcium chloride 20-40 wt%, 2, 4-D sodium 0.1-0.6 wt%, peregal 0.1-0.6 wt%, Mo 7.5-12.5 wt%, Zn 12.5- 25 wt%, and B 12.5-25 wt%. It is prepared through drying material, crushing, mixing and packing. The selenium-rich sweetener is applied to melon and fruit to increase selenium content, sweeten, raise quality and raise yield.

Description

technical field [0001] The invention relates to a foliar fertilizer mainly used for fruits and melons, in particular to a selenium-enriched sweetener and a preparation method thereof. Background technique [0002] Some of the existing foliar fertilizers used for fruits and melons do not have the function of supplementing selenium, such as commercially available fresh fruit sweeteners, etc.; although some have the function of supplementing selenium, they are not suitable for all fruits and melons, such as commercially available Although the selenium treasure can supplement selenium for apples, it is easy to cause phytotoxicity when applied to citrus and other fruit trees; especially the general selenium-rich foliar fertilizers do not pay attention to the effects of sweetening, flower preservation, fruit preservation and fruit cracking prevention The content of trace elements such as boron, molybdenum, zinc etc. that has is too little, has influenced the yield per unit area of...
