Description

Technical Field

[0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a selenium-rich daylily fertilizer and a preparation method thereof. Background Art

[0002] Selenium-enriched cultivation technology is an important technical means for the functionalization of current agricultural products. Through selenium element nutrition fortification technology, it is possible to produce selenium-enriched agricultural products in areas with selenium-poor soil. This technology is widely used in food crops and vegetable crops. Daylily is an important economic crop of the genus Hemerocallis, and its flower buds are harvested for consumption. At present, the production technology for selenium-enriched daylily has not been found. The present invention provides a safe and effective selenium fertilizer formula and a matching fertilization technology for the production of selenium-enriched daylily. Through selenium fertilizer and matching fertilization technology, the selenium content of dried daylily products is significantly increased in the production of selenium-enriched daylily, filling the gap in the technical field of selenium-enriched daylily production. Summary of the invention

[0003] The present invention aims to provide a selenium-rich daylily fertilizer and a preparation method thereof, so as to solve the problem of lack of fertilizer for selenium-rich daylily.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a selenium-rich daylily fertilizer, comprising the following components in weight percentage: 1.8-2.1 parts of sodium selenite solution, 5.5-6.5 parts of fulvic acid solution, 1.4-1.6 parts of gibberellin 3 solution, 0.4-0.6 parts of orange peel essential oil, and 980-1000 parts of water.

[0005] Preferably, the sodium selenite solution is 100 g / L, the fulvic acid solution is 80 g / L, the gibberellin 3 solution is 100 g / L, and the orange peel essential oil is 200 ml / L.

[0006] Preferably, the method for preparing the selenium-rich daylily fertilizer comprises the following steps:

[0007] Step 1: preparing mother liquor: slowly adding 100g of sodium selenite into a small amount of water and stirring to dissolve, and adding water to 1000ml after most of the solid is dissolved to prepare a sodium selenite solution; similarly preparing a fulvic acid solution and a gibberellin 3 solution; adding 200ml of orange peel essential oil into a beaker or other container, gradually adding water to 1000ml, keeping stirring during the addition process, and preparing the orange peel essential oil after the essential oil is evenly dissolved;

[0008] Step 2: Take four solutions respectively, mix them in proportion, and dilute them 100 times with water.

[0009] Step 3: Load the prepared fertilizer into the spray device for subsequent use.

[0010] Preferably, the method for applying selenium-rich daylily fertilizer comprises:

[0011] Step 1: Spray the leaves of the daylily 13 to 15 days before it starts to sprout. There is no strict spraying amount each time, just make sure that the leaves are sprayed.

[0012] Step 2: Spray the leaves of day lily 6 to 8 days before it bolts;

[0013] Step 3: Spray the leaves of the daylily for the final time after it bolts.

[0014] The principle and beneficial effects of this technical solution:

[0015] The invention provides a selenium-rich daylily special fertilizer and a preparation method and application thereof, which not only discloses a formula of the special fertilizer, but also proposes a set of corresponding fertilizer preparation methods for the formula, and also proposes in detail the application and application method of the special fertilizer. Spraying is performed every other week two weeks before bolting, so that the selenium content of the daylily flower buds is increased by 420% to 560%, reaching 0.14 to 0.19 mg / g.

[0018] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0019] Example:

[0020] 1. Preparation of selenium-rich daylily fertilizer:

[0021] (1) preparing a mother solution: slowly adding 100 g of sodium selenite to a small amount of water and stirring to dissolve, and after most of the solid is dissolved, adding water to 1000 ml to prepare a sodium selenite solution; similarly preparing a fulvic acid solution and a gibberellin 3 solution; adding 200 ml of orange peel essential oil to a container such as a beaker, gradually adding water to 1000 ml, and keeping stirring during the addition process, and preparing orange peel essential oil after the essential oil is evenly dissolved;

[0022] (2) Take the four solutions separately in the ratio of 2:6:1.5:0.5, mix them and dilute them 100 times with water.

[0023] (3) Load the prepared fertilizer into the spray device for subsequent use.

[0024] 2. Apply selenium-rich daylily fertilizer:

[0025] (1) Spray the leaves of the daylily 13 to 15 days before it starts to sprout. There is no strict spraying amount each time, just make sure that the leaves are sprayed.

[0026] (2) Spray the leaves of day lily 6 to 8 days before it bolts;

[0027] (3) Spray the leaves of the daylily for the final time after it has bolted.

[0028] 3. Comparative Experiment

[0029] In 2022 and 2023, the researchers conducted experiments in Dangliuzhuang Township, Yunzhou District, Datong City, using the above-mentioned method to prepare and apply fertilizers. After the day lily buds appeared, sampling began one week after the buds appeared, and sampling was carried out once every week. The day lily buds were taken and dried to determine the total selenium content and organic selenium content in the day lily buds.

[0030] like Figure 1 , Figure 2 As shown in Table 1, after experimental determination, the content of selenium and organic selenium in daylily buds increased significantly after the application of selenium fertilizer, which was significantly higher than the control. The content of selenium in daylily buds ranged from 0.0664 to 0.1779 mg / kg in 2022 and from 0.0842 to 0.2154 mg / kg in 2023. The content of organic selenium in daylily buds ranged from 0.0645 to 0.1675 mg / kg in 2022 and from 0.0772 to 0.2017 mg / kg in 2023.
