Abstract
The invention discloses foliage fertilizer for accelerating coloration of grape fruits as well as a preparation method and an application method thereof. The foliage fertilizer is prepared from the following materials in percentage by weight: 11-14% of MgCl2, 12-15% of KH2PO4, 18-20% of CaCl2, 6-8% of compound amino acid, 3-5% of Tween-20 and 42-45% of water. The preparation method of the foliagefertilizer comprises the following steps: taking the compound amino acid, adding the compound amino acid into water and uniformly mixing, heating till the temperature is 80-90 DEG C, then successivelyadding MgCl2, KH2PO4 and CaCl2, continuously stirring till the materials are completely dissolved, keeping the temperature for 48-50 minutes, then reducing the temperature to normal temperature, adding Tween-20 and uniformly stirring to obtain the foliage fertilizer. The foliage fertilizer for accelerating the coloration of the grape fruits is safe and non-toxic; the content of grape peel anthocyanin can be obviously increased.
Description
technical field [0001] The invention relates to a foliar fertilizer, in particular to a foliar fertilizer for promoting the coloration of grape fruit, and also relates to a preparation method and an application method of the foliar fertilizer. Background technique [0002] The skin of grape fruit is rich in color and phenotype when it is ripe, and there are many types of yellow-green, red, and black. Among them, red and black are rich in anthocyanins, which have the effects of preventing cardiovascular and cerebrovascular diseases, anti-aging, and anti-cancer, and are deeply loved by people. , but in actual cultivation, the grape fruit often has the problem of uneven and light coloring, which seriously affects its commerciality. [0003] Magnesium (Mg) can increase the content of photosynthetic pigments, and is also an activator of various photosynthetic enzymes, which can promote CO 2 The assimilation of sugar is beneficial to the synthesis of sugar in plants. Potassium (...
