Description

Technical Field

[0001] The invention belongs to the technical field of tiger tongue red fertilizers, and particularly relates to a special fertilizer for tiger tongue red and a preparation method thereof. Background Art

[0002] Ardisia mamillata Hance is a perennial evergreen shrub of the Myrsinaceae family. It is native to southern my country. In 1987, the Lushan Botanical Garden delegation discovered and introduced it in the deep mountains and old forests of Dayu County, Jiangxi Province. The whole plant of Ardisia mamillata Hance is purple-red, and its leaves are shaped like tiger tongues. It blooms from June to August, and its fruits are bright red. It bears fruit all year round. It is suitable for viewing as a shade-tolerant ground cover plant in Jiangnan gardens, and can also be potted in home rooms. Due to its unique appearance, it has won awards at exhibitions at home and abroad many times. Ardisia mamillata Hance not only has good ornamental value but also has high medicinal value: its ingredients such as borneol, caryophyllene, and bisabolol have multiple effects such as relieving asthma, anti-inflammatory, and healing ulcers. Among them, farnesol is a natural juvenile hormone that plays a gland-stimulating role in insect juvenile and adult stages.

[0003] General fertilizers on the market often pursue wide applicability, but ignore the special nutrient needs of different plants. For tiger tongue red, traditional fertilizers are prone to cause the lack or excess of certain key nutrients, or the nutrient release is slow and uneven, making it difficult for plants to absorb efficiently, affecting their health.

[0004] To sum up, the market urgently needs a compound fertilizer suitable for the growth of Tiger Tongue Red, which is developed based on the nutrient demand of Tiger Tongue Red and can effectively improve the quality of Tiger Tongue Red. Summary of the invention

Regularly check the solution state during this period to ensure that the calcium nitrate is completely dissolved and there is no visible sediment. After the calcium nitrate is completely dissolved, add 583g of potassium nitrate, and also use a water pump for circulation stirring. The water pump circulates for 30 minutes. During this period, continuously observe the solution state to ensure that the potassium nitrate is fully dissolved and the solution is transparent; obtain A mother solution; wherein the container is an opaque black plastic barrel; affix a detailed label on the outside of the black plastic barrel, including: preparation date, nutrient element name, store the prepared A mother solution in a cool, dark place, and regularly check the mother solution state;

[0036] S2. Prepare a container and 150 kg of well water, use an electronic scale to accurately weigh, 150 g of ammonium dihydrogen phosphate, 360 g of magnesium sulfate, and place them in dry, clean containers for standby use; then pour 150 g of ammonium dihydrogen phosphate into 150 kg of water, start the water pump and circulate and stir for 30 minutes until no precipitate is visible in the solution; then add 360 g of magnesium sulfate, start the water pump and circulate and stir for 30 minutes until the magnesium sulfate is dissolved and the solution is clear and transparent; obtain B mother solution; wherein the container is an opaque black plastic barrel; affix a detailed label on the outside of the black plastic barrel, including: preparation date, nutrient element name, store the prepared B mother solution in a cool, dark place, and check the mother solution status regularly;

[0037] S3, prepare a container and 100 kg of well water, the container is filled with water, 50 kg of well water is taken for subpackaging, the subpackaging well water is heated to 50 ° C using a heating rod, first add 2.8 grams of boric acid, stir thoroughly until completely dissolved, then add 2.1 grams of manganese sulfate, continue stirring until there is no precipitation, then add 0.2 grams of zinc sulfate, 0.1 grams of copper sulfate, 0.04 grams of ammonium molybdate in sequence, stirring after each addition, finally add 33 grams of chelated iron, and continue stirring until all substances are completely dissolved; obtain a nutrient solution, pour the dissolved nutrient solution back into the remaining well water, stirring while pouring; obtain C mother liquor;

[0038] Attach a detailed label to the outside of the black plastic barrel, including the preparation date and the name of the nutrient element. Store the prepared C mother solution in a cool, dark place and check the status of the mother solution regularly.

[0039] S4. Pour solution A, solution B and solution C into 600 kg of water in sequence and continue stirring to obtain a mother solution.

[0040] Preparation of working fertilizer: When using mother liquor to dilute working fertilizer, precipitation must be prevented during the addition of various mother liquors.

[0041] The preparation steps are as follows: put about 1 / 2-2 / 3 of the required preparation volume of clean water in the liquid storage tank, measure the required amount of A mother solution and pour it in, start the water pump to circulate or stir it to make it diffuse evenly, then measure the amount of B mother solution and slowly pour it into the clean water inlet of the liquid storage tank, let the water source dilute the B mother solution and bring it into the liquid storage tank, start the water pump to circulate or stir it evenly, and the amount of water added in this process has reached 80% of the total liquid volume. Finally, measure the C mother solution and add it to the liquid storage tank according to the method of adding the B mother solution, and the preparation of the working fertilizer is completed by circulating or stirring it evenly with the water pump.

[0042] After preparation, check whether the total volume of the fertilizer reaches the predetermined value, and use appropriate testing tools (such as pH meter, conductivity meter, etc.) to test the physical and chemical properties of the fertilizer to ensure that it meets the requirements for use.

[0043] Recording and storage: Record all dosage and operation steps in the preparation process in detail for future reference or traceability. Store the prepared fertilizer in a suitable environment, away from direct sunlight and high temperature to ensure stability and effectiveness.

[0044] Note:

[0045] In order to prevent the mother liquor from precipitation, nitric acid or sulfuric acid can generally be added to acidify it to pH 3-4 during long-term storage. At the same time, the prepared concentrated mother liquor should be kept in a cool and dark place. The mother liquor is best stored in a dark container.

[0046] When preparing working fertilizers by directly weighing nutrient element compounds, after adding calcium salts and salts that do not precipitate with calcium salts to the reservoir, do not immediately add phosphates and other compounds that do not precipitate with phosphates, but add them after the water pump has circulated for about 30 minutes or more.

[0047] Also be careful when adding trace element compounds; they should not be added immediately after adding macronutrients.

[0048] When preparing working fertilizer, if a small amount of precipitation is found, the circulation time of the water pump should be extended to dissolve the precipitation.

[0049] If it is found that a large amount of precipitation occurs due to excessive local concentration caused by adding compounds too quickly during the preparation process, and the precipitation cannot be dissolved after turning on the water pump for a long time, the fertilizer should be re-prepared.
