Problems solved by technology

[0004] Existing kale cultivation techniques mostly use measures such as induction of exogenous hormones, fertilizer application, and environmental improvement to increase the content of sulforaphane or selenium in kale stalks, but these cultivation measures are not effective in increasing the selenium content of kale stalks. At the same time, it caused the decrease of sulforaphane content, or while increasing the content of sulforaphane, there was no obvious change to the increase of selenium content
While increasing the selenium content in kale, its sulforaphane content is significantly increased, but

[0022] Among them, the source of sulfur element: magnesium sulfate (containing 26.67% sulfur, with a purity of 95%); the source of selenium element: commercially available sodium selenite (98% purity).

[0023] 2. Application method

[0024] Carry out foliar fertilization of kale with the foliar fertilizer prepared above, and the application method is as follows:

[0025] Kale seeds were purchased from Changsha Seed Market, sown on September 1, 2016, planted on September 25, 2016, and harvested on December 25, 2016. Three replicates were set up for each treatment, with 15 plants in each replicate, and substrate cu...

Abstract

The invention discloses a fertilizer capable of simultaneously improving contents of raphanin and organic selenium in Chinese kale bolt. The sulfur content in the fertilizer is 1 to 4 mM, and the selenium content in the fertilizer is 40 to 80 mu M. Meanwhile, the invention further provides a method capable of simultaneously improving contents of the raphanin and organic selenium in broccoli. The method comprises the step of leaf spraying the fertilizer on Chinese kale plants. By means of the foliar fertilizer disclosed by the invention, the content of the raphanin in the Chinese kale bolt is effectively improved by 13.5 to 59%, and the content of the selenium in the Chinese kale bolt is improved by 11.9 to 54.1 times.

Description

technical field [0001] The invention relates to a foliage fertilizer for kale, belonging to the field of fertilizers. Background technique [0002] Kale (Brassica oleracea L.) is an annual or biennial herbaceous plant of Brassica genus. Kale sprouts are rich in glucosinolates, among which glucoraphanin is hydrolyzed by myrosinase to generate sulforaphane, which has strong anti-cancer and anti-cancer functions. Sulforaphane is one of the substances with the best anti-cancer and anti-cancer effects in vegetables so far. It exists in large quantities in cruciferous vegetables, especially cabbage vegetables. Selenium is a non-metallic element that is closely related to human health. It has various biological functions such as enhancing human immunity, anti-aging, and anti-cancer. Appropriate selenium supplementation can reduce the incidence of diseases such as arteriosclerosis, hypertension, myocardial infarction, senile neurological insufficiency, memory and mental retardatio...
