Chromium rich liquid and its application in producing chromium (Cr3+) rich pumpkin

Abstract

The present invention discloses a chromium-rich liquor for producing chromium-rich pumpkin and its application for producing chromium-rich pumpkin. Its raw material composition includes Cr2O3:500mg / kg-3000mg / kg,KH2(PO4):5g / kg-10g / kg,K2MnO4:1g / kg- 5g / kg,Tween 20 2ml / L and the rest is water. Said invention also provides the concrete method and steps for applying said chromium-rich liquor.

Description

technical field

[0001] The invention belongs to the technical field of planting industry, relates to a foliar spray, in particular to a chromium-rich (Cr 3+ ) The chromium-rich solution of pumpkin and the chromium-rich solution are used to produce chromium-rich (Cr 3+ ) Pumpkin application. technical background

[0002] Chromium (Cr) is an essential trace element for animals and humans. It widely exists in soil and water, and has various chemical valence states: Cr(VI), Cr(II), Cr(III), Cr(IV), etc. Among them, the valence states of Cr(VI) and Cr(III) are relatively stable, and they account for a high proportion of the total chromium. Studies have shown that Cr(VI) is a carcinogen harmful to the human body, while Cr(III) is a chemical substance beneficial to the human body, and its main biological function is to bind to proteins, nucleic acids and various medium and small molecular weight ligands in the human body , in glucose metabolism and fat meta...

[0017] 1. Determine the formula of chromium-rich solution

[0018] (1) Determination of chromium source

[0019] The chromium source of chromium-rich solution can be Cr 2 o 3 or K 2 CrO 4 , in order to determine the source of chromium, a comparative test was carried out. Proceed as follows:

[0020] ①Cultivation of pumpkin samples Use farm pumpkin variety Xiaomopan as the cultivar. Spray the chromium-enriched solution on the leaves of the pumpkin in the evening on a sunny day in the early flowering period. The spraying amount is 50ml / plant / time to 100ml / plant / time, and then spray once a week 3 times in a row; then the pumpkin samples were obtained according to normal field management until the pumpkins grew and matured.
