Embodiment 1

[0021] The compound fertilizer for aloe of the present invention is proportioned according to the following proportions: 3.6 to 7.2 grams of urea, 1.7 to 3.4 grams of potassium sulfate, 7.3 to 14.6 grams of superphosphate, and 500 to 1000 grams of peat soil. Take the above ingredients and mix them in proportion.

[0022] The pH value, organic matter and element composition of the peat soil in the compound fertilizer are shown in Table 1 and Table 2.

Embodiment 2

[0028] See Table 3 for the fertilization scheme of Aloe plants.

[0029] Table 3. Aloe Vera Plant Fertilization Protocols

[0030]

[0031] Six months after the first fertilization, compared with the control group (F1N0), the fertilization program F2N1 increased the aloe curdlan content by 15% (P<0.01), and the fertilization program F2N2 increased the aloe curdlan content by 27% (P <0.01).

[0032] Six months after the first fertilization, compared with the control group (F1N0), the fertilization scheme F1N1 increased the O-acetyl content of the aloe gel by 12% (P<0.05), and the fertilization scheme F2N1 increased the O-acetyl content of the aloe gel. The content increased by 20% (P<0.01), and the fertilization program F2N2 increased the O-acetyl content of aloe gel by 29% (P<0.01).

[0033] Twelve months after the first fertilization, compared with the control group (F1N0), the fertilization program F1N1 increased the aloe curdlan content by 36% (P<0.05), and the fertili...

Embodiment 3

[0036] The content of aloe curdlan 3 months after the first fertilization is shown in Table 4, and the content of aloe curdlan has no significant change (P>0.05).

Abstract

A composite fertilizer used for aloe comprises 3.6-7.2 g of urea, 1.7-3.4 g of potassium sulfate, 7.3-14.6 g of calcium superphosphate and 500-1000 g of peat soil. A method for improving the content of polysaccharides and acemannan in aloe gel is characterized in that different proportions of a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer and peat soil are applied to substantially improve the content of polysaccharides and acemannan in (P<0.01 or P<0.05) aloe gel. The method can be used to prepare the special composite fertilizer used for aloe in order to improve the content of polysaccharides or acemannan in aloe gel.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of fertilizers, and in particular relates to the preparation of a compound fertilizer for increasing the content of aloe polysaccharides and a method for increasing the content of polysaccharides and acetylmannan in aloe gel. [0003] Background technique: [0004] Aloe polysaccharide is the main component of aloe vera gel, especially acetylated mannan, which can improve human immunity, significantly reduce cancer, AIDS symptoms and infection, and promote regeneration of burns caused by radiation. By measuring the content of O-acetyl group in aloe vera gel, the content of acetylated mannan can be evaluated. Increasing the content of aloe polysaccharides or acetylated mannan in aloe gel has broad application prospects. At present, there is no report on the compound fertilizer of the present invention used for aloe plants, and there is no relevant report on applying the compound fertilizer of the prese...
