Description

Technical Field

[0001] This invention belongs to the field of jasmine leaf technology, specifically, it relates to an antibacterial and anti-yellowing composition and treatment method suitable for cut jasmine leaves. Background Technology

[0002] As a common ornamental and cut flower crop, cut jasmine occupies an important position in the horticulture industry. However, it is susceptible to diseases and yellowing during its growth cycle, which seriously affects the quality and yield of the plant. In the seedling stage, the plant's root system is not yet fully developed and its antibacterial ability is weak, which easily leads to slow rooting. At the same time, yellowing often occurs due to nutritional imbalance during the true leaf growth stage. In particular, after entering the mature stage, the need for disease control of cut jasmine increases, and leaf yellowing occurs frequently.

[0003] However, the existing antibacterial and anti-yellowing compositions used in the mature jasmine often have antibacterial and anti-yellowing effects. However, when these compositions are applied, the leaves are easily irritated because they are drugs, which inhibits growth and prolongs the growth cycle.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the problem that existing antibacterial and anti-yellowing compositions used for mature jasmine, while effective in preventing these diseases, often irritate the leaves due to their chemical composition, thus inhibiting growth and prolonging the growth cycle, the basic concept of this invention is as follows:

[0006] An antibacterial and anti-yellowing composition suitable for cut jasmine, and a treatment method thereof, including an antibacterial and anti-yellowing composition for cut jasmine in the seedling stage, an antibacterial and anti-yellowing composition for cut jasmine in the growth stage, and an antibacterial and anti-yellowing composition for cut jasmine in the mature stage;

[0007] The specific components and duration of the antibacterial and antichlorosis composition for cut jasmine seedlings aged 1 to 30 days are as follows:

[0008] Day 1: Root irrigation with concentrated humic acid solution: The concentration of concentrated humic acid solution is diluted 1000 times.

[0009] Day 3: Bacillus subtilis root irrigation: Bacillus subtilis was diluted 800 times.

[0010] Day 7: Foliar application of micronutrient fertilizer;

[0011] Day 10: Foliar spraying of Bacillus subtilis: The Bacillus subtilis was diluted 1500 times.

[0012] Day 20: Foliar application of micronutrient fertilizer:

[0013] Day 30: Inspect the roots and leaves of the cut jasmine;

[0014] The specific composition of the antibacterial and anti-yellowing composition of the jasmine cut leaf antibacterial and anti-yellowing composition during the growth period is as follows:

[0015] The dilution ratio of pyraclostrobin and thiamethoxam is 1500 times:

[0016] For example: 10L of clean water:

[0017] Add 6.7 ml of azoxystrobin to 100 to 150 ml of warm water (25 to 35 degrees Celsius) and stir for 10 to 20 seconds.

[0018] Add 10 ml of thiazoxazine zinc to 100 to 150 ml of warm water (25 to 35 degrees Celsius) and stir slowly for 30 seconds.

[0019] Finally, pour the two mixed pyraclostrobin and thiamethoxam into the remaining water and stir.

[0020] Spray the mixed pyraclostrobin and thiamethoxam, along with water, onto the leaves of the cut jasmine.

[0021] The specific components and duration of the mature-stage cut jasmine antibacterial and anti-yellowing composition are as follows: e.g., 15 kg of water.

[0022] Mix 15 to 20 ml of water with 25% pyraclostrobin emulsifiable concentrate; mix 15 to 20 ml of water with 40% thiamethoxam suspension concentrate.

[0023] Stir the above ingredients one by one, then mix them into water, and then spray them onto the mature leaves.

[0024] Mix 10 to 15g of water with 10% chelated iron powder; or mix 15 to 20g of water with 10% chelated iron powder.

[0025] Mix 10 to 12 ml of water with 15% magnesium sugar alcohol.

[0026] Stir each of the above ingredients in turn, then mix them into water, and then spray the mixture onto the mature leaves.

[0031] To check if the true leaves are turning yellow, add chelated iron diluted 1500 times to a foliar fertilizer containing amino acids diluted 1500 times and then spray it onto the true leaves.

[0032] As a preferred embodiment of the present invention, the method of the antibacterial and anti-yellowing composition of jasmine in its growth stage further includes:

[0033] Pour the previously mixed pyraclostrobin and thiamethoxam into the remaining water and stir. Add chelated iron, magnesium oxychloride, and water-soluble fertilizer separately.

[0034] First, mix 10% to 15% of chelated iron and 15ml of water, then pour it into the well-stirred pyraclostrobin and thiamethoxam, and stir again for 10 seconds.

[0035] Then add 8% to 12% magnesium tartrate and 8 to 10 ml of water and mix. Then pour the mixture into the well-stirred pyraclostrobin, thiamethoxam, zinc thiamethoxam, and chelated iron and stir for 15 seconds.

[0036] Finally, add 20% N, 10% P and 20% K chemical components water-soluble fertilizer value and 20 to 30g of clean water, then pour it into the well-stirred pyraclostrobin, thiamethoxam zinc, chelated iron and sugar alcohol magnesium, stir for 30 minutes, and finally stir for 1 minute.

[0037] Afterwards, spray the mixed water-soluble fertilizer, pyraclostrobin, thiamethoxam, chelated iron, and sugar alcohol magnesium, along with the water-soluble fertilizer solution, onto the true leaves. This ensures that the disease is controlled while also promoting the growth of the cut jasmine.

[0038] Routine maintenance is recommended: once every 0-15 days, for 2-3 consecutive times.

[0039] To alleviate yellowing: When new leaves are yellowing, apply once every 7 days for two consecutive times;

[0040] Emergency treatment for diseases: After discovering lesions, apply once every 5-7 days, for a total of 2 times.

[0041] As a preferred embodiment of the present invention, the method of the mature-stage cut jasmine antibacterial and anti-yellowing composition further includes:

[0042] Add a high-potassium, medium-nitrogen, low-phosphorus water-soluble fertilizer to a mixture of pyraclostrobin emulsifiable concentrate, thiamethoxam zinc suspension concentrate, chelated iron and chelated iron powder, and sugar alcohol magnesium. The ratio of the added fertilizer is 15% nitrogen, 5% phosphorus, and 25% potassium. Then mix it with 20 to 25g of water and stir. Finally, add the mixture to the high-potassium, medium-nitrogen, low-phosphorus water-soluble fertilizer.
