Description

TECHNICAL FIELD

[0001] The application belongs to the field of cultivation of red mombin, and particularly relates to a special compound fertilizer for red mombin and application thereof. BACKGROUND

[0002] Red mombin (Nephelium lappaceum L.) is also known as hairy lychee, shousi and red hair fruit. It has an attractive appearance. The fruit of red mombin is a kind of tropical fruit tree with high economic value and enjoys high reputation in the market. Red mombin is a fruit tree and also an ornamental tree with high economic value. Red mombin needs 3 to 5 years from seedling to first fruiting. During this period, the fruit tree undergoes multiple stages such as seedling stage, growth stage, flowering stage and fruiting stage. The grower needs to carefully manage and care the fruit tree at each stage to ensure the healthy growth of the fruit tree. Therefore, the development of a special fertilizer for red mombin is crucial for the cultivation of red mombin. SUMMARY

[0003] The application provides a special compound fertilizer for red mombin and application thereof, which can effectively promote the growth of red mombin seedlings, ensure the healthy growth of the fruit tree and be beneficial to the cultivation and management of the fruit tree.

[0004] The technical scheme of the application is as follows:

[0005] The special compound fertilizer for red mombin comprises the following components in parts by weight: Bacillus velezensis HAB-2 0.3-1 parts, milk vetch root residue 10-20 parts, sugarcane residue 10-20 parts, mimosa 5-15 parts, fish meal 1-5 parts, fulvic acid 1-5 parts, brassinolide 1-3 parts and naphthalene acetic acid 0.1-0.3 parts. The preservation number of the Bacillus velezensis HAB-2 is CCTCC NO: M2015070, and the viable bacterial count is greater than or equal to 5x10 7 cfu / mL.

[0006] Further, the special compound fertilizer for red mombin comprises the following components in parts by weight: Bacillus velezensis HAB-2 0.5 parts, milk vetch root residue 15 parts, sugarcane residue 15 parts, mimosa 10 parts, fish meal 3 parts, fulvic acid 3 parts, brassinolide 2 parts and naphthalene acetic acid 0.2 parts.

[0007] Further, the milk vetch root residue is obtained by drying the residue after extracting active ingredients from milk vetch root; the sugarcane residue is obtained by drying the waste after removing water from the residue after sugarcane juice extraction; and the mimosa is obtained by drying the aboveground part of mimosa.

[0008] A preparation method of the special compound fertilizer for red mombin comprises the following steps:

[0009] (1) Take the formula amount of ox-dake residue, sugarcane residue and mimosa, crush them, add fish powder and water and mix evenly, then add Bacillus vesicles HAB-2 for culture, filter to obtain filtrate, and dry to obtain extract;

[0010] (2) Take the extract obtained in step (1), add the prescribed amounts of fulvic acid, brassinolide and naphthaleneacetic acid, and mix well to obtain the final product.

[0011] Furthermore, in step (1), the material is crushed through a 40-mesh sieve; water is added in a ratio of 3 times the total mass of the residue of *Euphorbia hirta*, sugarcane residue, and *Mimosa pudica*; and the mixture is cultured at 26–30°C for 3–5 days.

[0012] The above-described rambutan-specific compound fertilizer is used in the preparation of formulations that promote the growth of rambutan seedlings.

[0013] Furthermore, the aforementioned application involves foliar spraying of the diluted compound fertilizer.

[0014] Furthermore, in the aforementioned application, the compound fertilizer is diluted with water at a ratio of 100-200 times its weight.

[0015] Furthermore, in the aforementioned application, the foliar spray is applied until the leaf surface is moistened and droplets fall from the leaf edges.

[0016] Furthermore, the aforementioned application of the rambutan-specific compound fertilizer can improve the plant height and / or stem diameter of rambutan seedlings.

[0017] The beneficial effects of this invention are:

[0018] The rambutan-specific compound fertilizer of this invention uses *Smilax china* residue, sugarcane bagasse, *Mimosa pudica*, and fishmeal as substrates. It is fermented with *Bacillus belye* HAB-2 to obtain an extract, and then further supplemented with humic acid, brassinolide, and naphthaleneacetic acid to finally produce the compound fertilizer. This fertilizer significantly promotes the growth of rambutan seedlings, significantly increasing their height and stem diameter. While ensuring the healthy growth of rambutan seedlings, it also shortens the seedling cycle, thus having significant implications for the rambutan cultivation industry. Attached Figure Description

[0030] Its preparation method is the same as that in claim 1.

[0031] Example 3

[0032] A special compound fertilizer for rambutan, comprising the following components in parts by weight: Bacillus velezensis HAB-2 1 part, Millettia speciosa Champ. residue 20 parts, sugarcane residue 20 parts, Mimosa pudica 15 parts, fish meal 5 parts, fulvic acid 5 parts, brassinolide 3 parts, naphthalene acetic acid 0.3 part, and the viable count of the Bacillus velezensis HAB-2 is 5×10 9 cfu / mL.

[0033] Its preparation method is the same as that of claim 1.

[0034] In the above embodiments, the Millettia speciosa Champ. residue is obtained by drying the residue remaining after extracting the active ingredients from Millettia speciosa Champ. with water. The sugarcane residue is the waste remaining after removing water from the residue remaining after sugarcane is pressed for sugar. The Mimosa pudica is obtained by drying the upper part of Mimosa pudica.

[0035] Application of the above-mentioned special compound fertilizer for rambutan in the preparation of a preparation for promoting the growth of rambutan seedlings.

[0036] Investigation on the action effect of the compound fertilizer described in the present invention

[0037] Select young rambutan trees for the experiment on the action effect of the compound fertilizer. Fertilization experiments are carried out on rambutan seedlings planted in the current year (about 40 cm high). Different compound fertilizers are prepared and applied according to the compound fertilizer composition and preparation method in Table 1. Among them, the root irrigation treatment is carried out about 15 cm away from the tree base. All treatments are sprayed on the leaves or irrigated at the roots once every 15 days. After continuous treatment for 2 months, the growth of rambutan plants is counted. The results are shown in Table 2 and Figure 1 .

[0041] Table 2 Statistics on the influence of different compound fertilizers on the growth of rambutan plants

[0042]

[0043]

[0044] From Table 2 and Figure 1It can be seen that the rambutan growth in the three example groups was significantly improved, with more vigorous plant growth. Compared with treatment group 9, the increase in plant height and stem diameter was significantly increased. Treatment groups 4-6 used the same preparation method as the three example groups, but the composition of the compound fertilizer was changed. Treatment group 7 had no change in the composition of the compound fertilizer, but the preparation method was different from the example groups. The increase in plant height and stem diameter of rambutan plants was significantly reduced in both groups. In particular, the increases in plant height and stem diameter in treatment groups 4 and 5 were not only significantly lower than those in the example groups, but also slightly lower than those in treatment group 9, with little difference in plant growth compared to treatment group 9. Treatment group 8 used the same compound fertilizer composition and preparation method as the example groups, but applied it through root irrigation. Compared with treatments 4-7, although the increase in plant height was improved to varying degrees, the increase in stem diameter was significantly reduced, resulting in slender and tall rambutan seedlings, which was not conducive to later transplanting and affected the normal growth of the seedlings. Therefore, the compound fertilizer described in this invention can not only ensure the normal growth of rambutan seedlings, but also significantly increase the plant height and stem diameter of rambutan, thus having a significant growth-promoting effect.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
