Problems solved by technology

If the anthocyanin content in the pericarp is high, the litchi pericarp will have deep red color, good quality and high price. However, there is currently no foliar fertilizer specially used to increase the anthocyanin content in the pericarp of litchi, and there is no fertilizer for early-maturing and mid-late maturing litchi varieties. Foliar fertilizer that can promote redness of the fruit skin

Embodiment 1

[0037] This embodiment provides a kind of foliage fertilizer that improves the anthocyanin content of litchi pericarp, including the following components:

[0038] Amino acid 0.5%,

[0039] Phosphate fertilizer 0.1%,

[0040] Potassium fertilizer 0.5%,

[0041] Sugar 0.5%,

[0042] Trace element fertilizer 0.1%,

[0043] Abscisic acid 0.005%,

[0044] 5-Aminolevulinic acid hydrochloride 0.0005%,

[0045] The balance is water solvent.

[0046] In this example, the amino acid is phenylalanine, which is used as a direct precursor for the biosynthesis of anthocyanins and other flavonoids, and exogenous application of phenylalanine is beneficial to stimulate related regulatory genes And the expression of structural genes, thereby promoting the synthesis of anthocyanins, and realizing the completion of crop color change in advance.

[0047] In this embodiment, the phosphate fertilizer and potassium fertilizer are superphosphate.

[0048] In this embodiment, the sugar is sucr...

Embodiment 2

[0061] Potassium fertilizer 0.3%,

[0062] Sugar 0.2%,

[0063] Trace element fertilizer 0.3%,

[0064] Abscisic acid 0.01%,

[0065] 5-Aminolevulinic acid hydrochloride 0.0008%,

[0066] The balance is water solvent.

[0067] In this embodiment, the amino acid is a mixture of phenylalanine, L-glutamic acid, leucine and arginine in a ratio of 1:1:1:1.

[0068] In this embodiment, the phosphate fertilizer and potassium fertilizer are a mixture of calcium superphosphate, triple superphosphate, calcium potassium chloride, potassium sulfate, and potassium dihydrogen phosphate in a ratio of 1:1:1:1:1.

[0069] In this embodiment, the sugar is glucose.

[0070] In this embodiment, the medium and trace element fertilizer is sodium tetraborate.

[0086] 5-Aminolevulinic acid hydrochloride 0.001%,

[0087] The balance is water solvent.

[0088] In this embodiment, the amino acid is leucine.

[0089] In this embodiment, the phosphate fertilizer and potassium fertilizer are calcium potassium chloride.

[0090] In this embodiment, the sugar is glucose.

[0091] In this embodiment, the medium and trace element fertilizer is boric acid.

[0092] A kind of preparation method of the foliage fertilizer that improves litchi peel anthocyanin content comprises the steps:

[0093] Step (1) Add part of the water solvent, trace element fertilizer, sugar, and abscisic acid into the sti...

Abstract

The invention provides a foliar fertilizer for increasing the anthocyanin content of litchi pericarp. The foliar fertilizer comprises the following components: 0.5%-1.5% of amino acid, 0.1%-0.8% of phosphate fertilizer, 0.1%-0.5% of potash fertilizer, 0.05%-0.5% of sugar, 0.001%-0.5% of trace element fertilizer, 0.0005%-0.001% of 5-aminolevulinic acid hydrochloride, 0.005%-0.02% of abscisic acid and the balance water solvent. The foliar fertilizer for increasing the anthocyanin content of litchi pericarp, provided by the invention, has a relatively good use effect, and the input cost of usersis also reduced, so that the foliar fertilizer has great economic value and use value.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a foliar fertilizer for increasing the anthocyanin content of litchi pericarp and its application method. Background technique [0002] Litchi is native to China and is a subtropical fruit tree of the genus Litchi in the Sapindaceae family. The germplasm resources are very rich and have high edible value. Germplasm or cultivation relationship, the pericarp often has low anthocyanin content, and the exocarp is poorly colored, showing that a small part of the pericarp turns red while the other part is still green, or the exocarp is reddish shallow case. Litchi fruit coloring is poor, the appearance shows that the fruit is immature or the quality of the fruit is not high, and the sales price is not high, but the coloring of litchi is good, the fruit quality is high, and the commodity price is high. Therefore, fruit coloring is a very important indicator for evaluatin...
