Embodiment 1

[0019] Prepare the fertilizer, and the formula is shown in Table 1.

[0020] (1) Source of sucrose: commercial white granulated sugar;

[0021] (2) Source of citric acid: commercially available anhydrous ammonium citrate (content≧99.9%);

[0022] (3) Source of methyl jasmonate: commercially available methyl jasmonate (purity 98%);

[0023] (4) Source of phenylalanine: commercially available L-phenylalanine (content ≧98.5%).

[0024] Formulate according to the orthogonal design scheme (blank control is set), dissolve each component of the above-mentioned fertilizer in water, prepare to a suitable concentration and mix evenly.

[0025] Potato virus-free seed potatoes (variety name: Ziyang) were provided by Hunan Potato Engineering Technology Research Center. They were sown on December 25, 2012 and harvested on April 27, 2013. Three replicates were set up for each treatment, with 120 plants per replicate.

[0026] Potato planting was implemented according to the orthogonal de...

Abstract

The invention discloses a fertilizer and method for increasing the anthocyanin content in purple potatoes. The fertilizer contains 1-5% of white granulated sugar, 100-300ppm of ammonium citrate, 50-100ppm of methyl jasmonate and 20-40ppm of phenylalanine. According to the invention, the anthocyanin content in purple potatoes can be obviously increased, thereby solving the problem that the anthocyanin content in purple potatoes is low. Anthocyanin has very high economic value; and the invention has wide application prospects.

Description

technical field [0001] The invention relates to a fertilizer and a method for increasing anthocyanin content in purple potatoes. Background technique [0002] "Anthocyanin" is a natural and powerful free radical scavenger, which has preventive and therapeutic effects on more than 100 diseases. Anthocyanin is known as the seventh largest after water, protein, fat, carbohydrates, vitamins and minerals. essential nutrients. "Anthocyanin" is the most direct, most effective and safest free radical scavenger discovered by the scientific community to prevent and treat diseases and maintain human health. Its ability to eliminate free radicals is 20 times that of vitamin C and 50 times that of vitamin E. Anthocyanin is the only substance that can clear free radicals and protect brain cells through the blood-brain barrier. At the same time, it can reduce some harms caused by antibiotics to the human body. Purple potatoes can be used as one of the main raw materials for extracting "an...
