Problems solved by technology

Among the existing selenium-enriched fertilizers, the added selenium is mainly a separate selenium source material, or it is compatible with other inorganic fertilizers. There are many problems in practical application, such as low plant utilization rate and high concentration, which will cause damage. The phenomenon of leaf damage and fruit; as a base fertilizer, it is easy to pollute the soil and so on

Embodiment 1

[0017] 1) Weigh 2g of agricultural chitosan oligosaccharide and dissolve it in 100mL of water completely under stirring.

[0018] 2) Add 6g of sodium selenite, stir to dissolve.

[0019] 3) Add 1g each of other trace elements (Zn+B) and stir to dissolve.

[0020] 4) Weigh 4 mg of brassinolide, dissolve it in 10 mL of 95% ethanol, slowly add it to the solution obtained in step 3, add 1 g of Tween-80, and continue stirring.

[0021] 5) Adjust the pH value to 6.5 with acetic acid, adjust the volume to 200ml with water, and stir evenly to prepare a selenium-enriched organic nutrition regulator containing 30g / L of selenium and 20mg / L of brassinolide.

[0022] from figure 1 It can be seen that the particle size distribution of the selenium-rich organic nutrition regulator of the present embodiment is detected by zeta-sizer, and it can be seen that the size distribution is 300-1000nm, the average particle diameter is 333nm, and the dispersion coefficient is 0.244, which shows that ...

Embodiment 2

[0025] 1) Weigh 2g of chitosan powder and dissolve it completely in 100mL of 2% acetic acid solution under stirring.

[0026] 2) Add 6g of sodium selenite, stir to dissolve.

[0027] 3) Add 1 g each of zinc and boron to the solution obtained in step 2, and stir evenly.

[0028] 4) Weigh 4 mg of brassinolide, dissolve it in 10 mL of 95% ethanol, slowly add it to the solution obtained in step 3, and add 1 g of Tween-80.

[0029] 5) After adjusting the pH value to 5.5 with an acetic acid solution, use an acetic acid solution with a concentration not higher than 2% to set the volume to 200 mL, and stir for 30 minutes to obtain 30 g / L of selenium and 20 mg / L of brassinolide. Selenium-enriched organic nutrition regulator.

[0030] The selenium-enriched organic nutrient regulator obtained in this embodiment should be diluted with 30 kg of water per 20 mL of selenium-rich organic nutrient regulator during use, and sprayed at the full development stage of rice flag leaves, which can ...

Embodiment 3

[0032] 1) Weigh 2g of agricultural chitosan oligosaccharide and dissolve it in water completely under stirring.

[0033] 2) Add 6g of sodium selenite, stir to dissolve.

[0034] 3) Add 1g each of other trace elements (Zn+B) and stir to dissolve.

[0035] 4) Weigh 4 mg of brassinolide, dissolve it in 10 mL of 95% ethanol, slowly add it to the solution obtained in step 3, and add 1 g of Tween-80.

[0036] 5) Adjust the pH value to 6.0 with acetic acid, stir evenly, and adjust the volume to 200mL with water to prepare a selenium-enriched organic nutritional regulator containing 30g / L selenium and 20mg / L brassinolide.

[0037] The selenium-enriched organic nutrient regulator obtained in this embodiment should be diluted with 30 kg of water per 20 mL of selenium-rich organic nutrient regulator during use, and sprayed at the full development stage of rice flag leaves, which can effectively improve the quality of rice and improve the quality of rice by 0.1 -Selenium content of 0.2m...

Abstract

The invention discloses a rich selenium organic nutrition regulator and the preparation method thereof. The regulator mainly contains the following ingredients: chitin fiber of 15-50 g / L, selenium sourced matter of 10-50 g / L calculated by selenium, brassin lactone of 10-60 mg / L, microelement content of 10-30 g / L in soil, emulsifier of 0.5-5 g / L, and others are acetic acid solution or water for thedissolution of the chitin fiber as well as the alcohol for the dissolution of the brassin lactone. The invention has the preparation method that the chitin fiber is fully dissolved in the acetic acidsolution or water and is added with the selenium sourced matter and the microelement while mixing. At length, the brassin lactone dissolved by the alcohol and the emulsifier are added, and then thevo lume is determined with the acetic acid solution or water, thereby making each ingredient be up to the designated density, and being safe to continue the mixing. The invention not only gives full playto the role of brassin lactone to regulate the growth of plants, but also effectively control the absorption of crops on selenium, thus the injury of selenium to crops is avoided and the effect ofthe reasonable absorption of selenium is realized. Moreover, the selenium is rich in the cluster of crops, therefore safe agricultural products rich in the selenium can be produced.

Description

technical field [0001] The invention relates to an organic nutrient regulator applied to crops, in particular to a selenium-enriched organic nutrient regulator and a preparation method thereof. technical background [0002] Selenium is one of the essential trace elements for human beings. Numerous scientific studies have shown that selenium has the functions of anti-cancer and anti-cancer, enhancing human immune function, lowering blood sugar, protecting cardiovascular and cerebrovascular, preventing cataracts and delaying aging. Selenium upsurge. There are currently three main ways to supplement selenium for the human body, inorganic selenium supplementation, synthetic selenium supplementation and natural organic selenium supplementation. Selenium has attracted more and more attention due to its advantages such as good effect, no side effects and wide sources. Natural organic selenium supplementation mainly lies in food supplementation, which is to eat some safe selenium-...
