Embodiment 1

[0018] Prepare the fertilizer, and the formula is shown in Table 1.

[0019] Nitrogen source: urea (46.7% nitrogen, 95% purity).

[0020] Sulfur source: magnesium sulfate (26.67% sulfur, 95% purity).

[0021] Source of methyl jasmonate: commercially available methyl jasmonate (purity 98%).

[0022] Broccoli is fertilized with the fertilizer prepared above, and the application method is as follows:

[0023] Broccoli seeds (variety name: Manduo Green) were purchased from the Changsha Seed Market, sown on August 1, 2010, planted on August 26, 2010, and harvested on November 27, 2010. Three replicates were set up for each treatment, and each replicated had 10 plants. Both hydroponics and soil cultivation are adopted.

[0024] The hydroponic broccoli is sown in the perlite matrix to grow seedlings, planted in the perlite:river sand (volume ratio 1:1) matrix for management, the nutrient solution is Hogland culture solution, and the broccoli is sprayed every ten days after buddi...

Embodiment 2

[0030] Prepare fertilizer, formula is as table 2, and raw material source is with embodiment 1.

[0031] Fertilize Chinese kale with the fertilizer prepared in this embodiment, and the application method is as follows:

[0032] Kale seeds (variety name: Zhonghua Kale) were purchased from the Changsha Seed Market, sown on September 1, 2010, planted on September 24, 2010, and harvested on November 10, 2010. Three replicates were set up for each treatment, and each replicated had 10 plants. Both hydroponics and soil cultivation are adopted.

[0033] The hydroponic kale is sown in the perlite substrate to grow seedlings, planted in the perlite:river sand (volume ratio 1:1) substrate for management, the nutrient solution is Hogland culture solution, and the kale is sprayed every seven days after 5 true leaves (treatment) or not sprayed (control) with the formulated fertilizer. In order to avoid nutrient deficiency, 1000 ml of nutrient solution was supplemented every 7 days. The ...

Abstract

The invention discloses a fertilizer capable of improving the content of sulforaphane in cultivated vegetable and an application method thereof. The fertilizer contents 30-150ppm of nitrogen, 8-128ppm of sulfur and 25-200ppm of methyl jasmonate. The method for improving the content of sulforaphane in the cultivated vegetable by using the fertilizer is as follow: the fertilizer is applied to vegetable plants. The fertilizer and the method provided by the invention can be used for solving the problem that the content of sulforaphane is low and have wide application prospects.

Description

technical field [0001] The invention relates to a fertilizer and a method for increasing the content of sulforaphane in cultivated vegetables. Background technique [0002] Broccoli is one of the most consumed and imported vegetables in developed countries, mainly because of its sulforaphane content. Sulforaphane has a strong effect of promoting the detoxification of carcinogens and inhibiting the growth of cancer cells. It is the natural active ingredient with the strongest anticancer activity found in vegetables so far. Sulforaphane is only found in cruciferous vegetables, and the content of sulforaphane in broccoli ranks first among all vegetables. Studies have shown that the anti-cancer components in broccoli have significant inhibitory effects on lung cancer, breast cancer, rectal cancer, colon cancer, prostate cancer, and pancreatic cancer. However, the content of sulforaphane in broccoli is low, and it is difficult to achieve industrial production by chemical synthe...
