Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, specifically to a turmeric fertilizer and its application method. Background Technology

[0002] Curcuma zedoaria is a plant belonging to the genus Curcuma in the ginger family (Zingiberaceae). Its tuberous roots and rhizomes are used medicinally, and it is now mainly cultivated artificially. Curcuma zedoaria prefers a warm, humid, and sunny climate, and is drought-tolerant and flood-resistant, but susceptible to frost. It thrives in loose, well-drained, and deep alluvial or sandy loam soils. Curcuma zedoaria flowers very little, and its seeds are mostly immature; therefore, it is propagated using ginger rhizomes.

[0003] Curcuma zedoaria is pungent, bitter, and warm in nature, and enters the liver and spleen meridians. It has the effects of promoting qi circulation, breaking up blood stasis, eliminating stagnation, and relieving pain. Clinically, it is used to treat abdominal masses, amenorrhea due to blood stasis, abdominal distension due to food stagnation, and early-stage cervical cancer. Modern research shows that Curcuma zedoaria oil has anti-tumor, antibacterial, antiviral, antioxidant, and hepatoprotective activities. Its anti-tumor active substances are mainly curcumol, elemol, and curcumone. The beneficial effects of elemol include:

[0004] (1) It directly kills tumor cells, and the conventional dose has no effect on normal cells (such as peripheral blood leukocytes);

[0005] (2) By interfering with the growth and metabolism of tumor cells, it induces rapid apoptosis in tumor cells. It acts on the regulatory points of the cell cycle S phase and G2 and M phases, arresting S phase cells from entering the G2+M phase, reducing the division ability of tumor cells, and inhibiting their proliferation;

[0006] (3) By inducing changes in the synthesis and distribution of HSP70 protein in tumor cell membranes, the immunogenicity of tumor cells was enhanced, and tumor recurrence and metastasis were inhibited.

[0007] (4) It has fewer toxic side effects and has less impact on normal cells and surrounding white blood cells.

[0008] Elecithin has high medicinal value, and currently, increasing the elecithin content in Curcuma zedoaria is a challenge. Summary of the Invention

[0009] In view of the problems existing in the prior art, the present invention provides a turmeric fertilizer and a fertilization method, the purpose of which is to increase the yield of elemol.

[0010] The technical solution adopted in this invention is as follows:

[0011] A method for fertilizing with Curcuma zedoaria includes the following steps:

[0012] S1. Prepare fertilizer for applying turmeric in advance;

[0013] S2. When planting the turmeric rhizomes, apply base fertilizer between adjacent rhizomes, cover with soil and form ridges, and spray with enzyme liquid fertilizer.

[0014] S3. Apply additional fertilizer to the turmeric. The additional fertilizer application is carried out in three stages. Each time additional fertilizer is applied, spray the corresponding enzyme liquid fertilizer.

[0015] Preferably, the specific process of S1 is as follows:

[0016] Prepare an appropriate amount of well-rotted animal and plant matter, human and animal excrement, ammonium ion fertilizer, and phosphorus and potassium fertilizer, mix and ferment them, and use them as fertilizer for applying Curcuma zedoaria.

[0017] Preferably, the specific process of S2 is as follows:

[0018] Select loose, fertile, and deep sandy loam soil to plant the turmeric rhizomes. Apply base fertilizer between adjacent rhizomes. The base fertilizer per acre is a mixture of 80 kg of decomposed animal and plant matter, 60 kg of human and animal manure, 5 kg of ammonium ion fertilizer, and 5 kg of phosphorus and potassium fertilizer, which is fermented and then covered with soil to form ridges 25-35 cm high.

[0019] Preferably, the additional fertilization in S3 is carried out in three separate processes as follows:

[0020] The first fertilization is applied when the turmeric seedlings are 25cm tall, using 15-35kg of compound fertilizer per mu (approximately 0.067 hectares). The second fertilization is applied 50-70 days after the first fertilization, using 30-40kg of a fermented mixture of well-rotted animal and plant manure, ammonium ion fertilizer, and phosphorus and potassium fertilizer per mu. The third fertilization is applied 40-60 days after the second fertilization, using 30-45kg of a fermented mixture of well-rotted animal and plant manure, ammonium ion fertilizer, and phosphorus and potassium fertilizer per mu. The fertilization method involves digging a hole 5-15cm from the center of the turmeric seedling, applying the fertilizer, and then backfilling with soil.

[0021] Preferably, the process of spraying the corresponding enzyme liquid fertilizer each time additional fertilizer is applied in S3 is as follows:

[0022] After the first fertilization, spray with enzyme liquid fertilizer at a volume ratio of 1:200-300; after the second fertilization, spray with nitrogen-rich enzyme liquid fertilizer 1-2 times at a volume ratio of 1:200-300; after the third fertilization, spray with potassium-rich enzyme liquid fertilizer once at a volume ratio of 1:200-300.

[0023] Furthermore, the enzyme liquid fertilizer is obtained by mixing rock sugar, vegetable and fruit waste, and water in a volume ratio of 1:4:8 and then anaerobically fermenting it for 2 months.

[0024] Furthermore, the nitrogen-enriched enzyme liquid fertilizer is made by adding nitrogen-rich organic matter such as soybeans or oilseeds to the enzyme liquid fertilizer; the potassium-enriched enzyme liquid fertilizer is made by adding potassium-rich orange peel to the enzyme liquid fertilizer.

[0025] A turmeric fertilizer, wherein the turmeric fertilizer is a fertilizer made by fermenting a mixture of decomposed animal and plant matter, human and animal excrement, ammonium ion fertilizer, and phosphorus and potassium fertilizer.

[0026] In summary, the beneficial effects of the present invention are as follows:

[0027] 1. This invention improves the yield of Curcuma zedoaria by standardizing its cultivation and applying fertilizers scientifically, thus providing more high-quality raw materials for the extraction of elemene and increasing the yield of elemene.

[0028] 2. This invention obtains fertilizer by mixing and fermenting appropriate proportions of decomposed animal and plant matter, human and animal excrement, ammonium ion fertilizer, and phosphorus and potassium fertilizer, which promotes the growth of Curcuma zedoaria and improves its yield and quality.

[0029] 3. This invention involves applying fertilizer to Curcuma zedoaria three times, with corresponding enzyme liquid fertilizer sprayed during each application, thus increasing the yield of Curcuma zedoaria through reasonable fertilization. Detailed Implementation

[0031] Curcuma zedoaria should be planted in the warm, humid, and sunny low mountains, hills, or valleys below 800 meters above sea level in Dazhou, Sichuan Province. Dazhou has a subtropical humid monsoon climate, and the low mountains, hills, and valleys below 800 meters above sea level have a mild climate with warm winters, early springs, hot summers, and cool autumns, distinct seasons, a long frost-free period, and simultaneous rain and heat. The average annual temperature is between 14.7℃ and 17.6℃, and the frost-free period is about 300 days. The city has abundant rainfall, with an average annual rainfall of 1076 to 1270 mm, which is conducive to the growth of Curcuma zedoaria. The entire process of harvesting and sowing turmeric begins in mid-February and ends at the end of February each year. The reason for choosing to harvest and sow turmeric from mid-February to the end of February each year is that the temperature in Dazhou in February has reached the suitable planting temperature for turmeric. Completing the harvesting and sowing of turmeric in a short period of time is conducive to locking in the proportion of elemol in turmeric, thereby increasing the yield of elemol.

[0032] A method for fertilizing with Curcuma zedoaria includes the following steps:

[0033] S1. Prepare fertilizer for applying turmeric in advance;

[0034] S2. When planting the turmeric rhizomes, apply base fertilizer between adjacent rhizomes, cover with soil and form ridges, and spray with enzyme liquid fertilizer.

[0040] The specific process for additional fertilization in S3, which is carried out in three stages, is as follows:

[0041] The first fertilization is applied when the turmeric seedlings are 25cm tall, using 35kg of compound fertilizer per mu. The second fertilization is applied 70 days after the first fertilization, using a fermented mixture of well-rotted animal and plant manure, ammonium ion fertilizer, and phosphorus and potassium fertilizer per mu. The third fertilization is applied 60 days after the second fertilization, using a fermented mixture of well-rotted animal and plant manure, ammonium ion fertilizer, and phosphorus and potassium fertilizer per mu. The fertilization method is to dig a hole 10cm from the center of the turmeric seedling, apply the fertilizer, and then backfill with soil.

[0042] In S3, the specific process of spraying the corresponding enzyme liquid fertilizer each time additional fertilizer is applied is as follows:

[0043] After the first fertilization, spray with enzyme liquid fertilizer at a volume ratio of 1:200-300; after the second fertilization, spray with nitrogen-rich enzyme liquid fertilizer 1-2 times at a volume ratio of 1:200-300; after the third fertilization, spray with potassium-rich enzyme liquid fertilizer once at a volume ratio of 1:200-300. The enzyme liquid fertilizer is obtained by mixing rock sugar, vegetable and fruit waste, and water at a volume ratio of 1:4:8 and then anaerobically fermenting for 2 months. Nitrogen-rich enzyme liquid fertilizer is obtained by adding nitrogen-rich organic matter such as soybeans or oilseeds to the enzyme liquid fertilizer; potassium-rich enzyme liquid fertilizer is obtained by adding potassium-rich orange peel to the enzyme liquid fertilizer.

[0044] In this embodiment, the yield of Curcuma zedoaria is 2439 kg / mu.
