Selenium-rich sweetener and its preparing method

Abstract

The invention discloses a selenium-enriched sweetener, which is composed of the following components and contents (weight percentage): 10% to 20% of selenate, 5% to 10% of sodium binitrophenolate, rare earth and / or chloride Calcium 20% ~ 40%, 2,4-D sodium salt 0.1% ~ 0.6%, Pingjia 0.1% ~ 0.6%, molybdenum 7.5% ~ 12.5%, zinc 12.5% ​​~ 25%, boron 12.5% ​​~ 25%. Its preparation method includes firstly drying and pulverizing the components, that is, the raw materials, and all the preparation procedures after the raw materials are dried are carried out under the condition of air humidity below 75%; the following process steps can be followed: ① raw materials are dried; ② raw materials are crushed; ③ compound Sodium nitrophenolate+zinc+molybdenum+2,4-D sodium salt is pulverized and stirred evenly, and sealed; ④Boron+selenate+Pingpingjia is stirred evenly, and then mixed with "③"; and / or calcium chloride mixture; ⑥ Weigh and pack in moisture-proof packaging. The selenium-enriched sweetener makes melons and fruits rich in selenium and increases sweetness, which is beautiful and high-quality, while preserving flowers and fruits, increasing yield and lowering the price.

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...
