Description

Technical Field

[0001] The invention relates to the technical field of fertilizer fermentation, and in particular to a Phalaenopsis microbial fermentation fertilizer and a preparation method thereof. Background Art

[0002] Phalaenopsis, the scientific name of which means "orchid like a butterfly" in Greek, can survive by absorbing nutrients from the air. It is classified as an aerial orchid and can be said to be a large family of tropical orchids. Its plants are very peculiar, with neither stolons nor pseudobulbs. Phalaenopsis is a parasitic orchid, and mainly prefers substrates such as moss and charcoal for cultivation, requiring little fertilizer. It is best to put bean cake and rice water together in a container and ferment them, which is an all-purpose fertilizer. Because the nitrogen, phosphorus and potassium content is reasonable, it is very suitable for Phalaenopsis.

[0003] Phalaenopsis is mainly fertilized with nitrogen fertilizer during the growth period, and mainly with phosphorus fertilizer during the flowering period. The fertilizer used for Phalaenopsis should be formulated according to the physiological characteristics and fertilizer requirements of flowers. It should be rich in amino acids and large, medium and trace elements required by flowers, with comprehensive and balanced nutrients, which can improve the potting soil, promote the formation of chlorophyll, make the branches and leaves luxuriant, the stems thick, and improve the cold resistance, disease resistance, stress resistance and ornamental value of flowers. The fertilization principle of Phalaenopsis is to apply thin fertilizer frequently. However, the flowering period of Phalaenopsis flowers is only 110 days at most. During the flower cultivation process, the fertility of the soil is insufficient or unreasonable, and the root growth ability is reduced, resulting in the inability of the Phalaenopsis flower period to extend to the due time. The technology of soilless cultivation of Phalaenopsis in the prior art has problems such as Phalaenopsis being unable to grow and develop normally due to insufficient culture medium or the reduced synthesis of organic matter in Phalaenopsis, which makes it difficult for Phalaenopsis to bloom, rots roots, and cannot be quickly put on the market. Summary of the invention

[0004] The purpose of the present invention is to provide a Phalaenopsis microbial fermentation fertilizer and a preparation method thereof, which can improve the fertility in the soil and the growth ability of its root system so that it can grow normally, thereby avoiding the problems of Phalaenopsis being difficult to bloom and easy to rot its roots.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] The invention discloses a Phalaenopsis microbial fermentation fertilizer. The raw materials of the microbial fermentation fertilizer include the following proportions by mass: 20-30% of soybean meal, 12-16% of peanut shells, 15-19% of corn cobs, 45-55% of corn stalks, 10-14% of bagasse, 20-30% of fish meal, 20-30% of fish viscera, 15-25% of shrimp shells, 30-40% of earthworm manure, 2-3% of seaweed extract, 3-5% of humic acid, 1-2% of brown sugar, 3-5% of superphosphate and 0.5-1% of microbial agent.

[0007] A method for preparing Phalaenopsis microbial fermentation fertilizer comprises the following steps:

[0008] Step 1: Raw material pretreatment: crush soybean meal, peanut shells and sugarcane bagasse to make the particle size uniform, rinse the fish viscera and shrimp shells with clean water to remove impurities, and then chop them into smaller pieces, remove impurities and disinfect the fish meal to kill harmful microorganisms and parasite eggs that may exist in it;

[0009] Step 2, mixing ingredients: evenly mix 25% soybean meal, 14% peanut shells, 17% corn cobs, 50% corn stalks, 12% bagasse, 25% fish meal, 25% fish viscera, 20% shrimp shells, and 35% earthworm manure for later use;

[0010] Step 3: Add additives: add 2% seaweed extract, 4% humic acid, 2% brown sugar, and 4% superphosphate to the mixed ingredients and stir to mix evenly;

[0011] Step 4: Adjust the moisture content: gradually add an appropriate amount of water to the stirred material, stirring while adding water, so that the moisture content of the material reaches 55% to 65%;

[0012] Step 5: pH adjustment: Use pH test paper to test the pH of the mixed materials, add lime powder according to the test results, and adjust the pH value of the materials to the range of 6.5-7.5. After adding lime powder, stir again to ensure that the pH is evenly adjusted;

[0013] Step 6: Inoculation of microbial agents: Sprinkle the microbial agents evenly on the surface of the material with adjusted moisture, and then stir again to inoculate 0.8% of the microbial agents on the material, and then stir for 15 to 20 minutes to allow full contact and ensure that the microbial agents are evenly distributed in the material;

[0014] Step 7, composting and fermentation: In a well-ventilated, high-lying and rainproof site, first spread a layer of dry straw or stalks 10 to 15 cm thick to facilitate air circulation, and pile the moisture-adjusted materials into a long pile of 1.5 to 2 meters wide and 1 to 1.2 meters high. After the pile is completed, cover the top and surrounding areas with a layer of plastic film to keep warm and moisturize.

[0015] Step 8. Temperature monitoring and compost turning: Insert a thermometer inside the compost and pay close attention to temperature changes. In the early stage of fermentation, the temperature inside the compost will gradually rise. When the temperature reaches 55-60°C, turn the compost for the first time, turning the outer layer of materials to the middle and the inner layer of materials to the outer layer, so that the entire compost body ferments evenly;

[0016] Step 9, secondary fermentation: After the temperature stabilizes, stack the materials again, appropriately lower the stack height to 0.8-1 meter, keep ventilation, and last for 10-15 days. After the fermentation is completed, the materials should be dark brown, loose in texture, without obvious odor, and have a light humus smell, indicating that they are basically decomposed;

[0017] Step 10: Drying and screening: Spread the decomposed materials in a well-ventilated place to dry in the sun to reduce the moisture content to below 30%, and then use a sieve to remove large pieces of materials and impurities that are not fully decomposed.

[0018] Further: in step 1, the particle size of the soybean meal, peanut shells and bagasse after crushing is controlled to be 2 to 5 mm.

[0019] By adopting the above technical solution, the surface area of ​​the material can be increased, making it easier for microorganisms to decompose it.

[0020] Further: in step six, the microbial agent is one or more of Bacillus subtilis, Bacillus licheniformis, photosynthetic bacteria, lactic acid bacteria, and yeast.

[0021] Further: In step seven, the long pile should have several ventilation holes at certain intervals.

[0022] By adopting the above technical solution, it is possible to prevent the internal temperature of the pile from being too high and lacking oxygen.

[0023] Further: in step eight, whenever the temperature reaches above 55°C again, the pile is turned, generally once every 2 to 3 days, and after 3 to 4 times of turning the pile, the temperature inside the pile is gradually stabilized at around 40°C.

[0024] Further: In step nine, during the secondary fermentation, water can be sprayed appropriately according to the dryness and wetness of the material to maintain a certain humidity.

[0025] By adopting the above technical solution, the main purpose is to allow microorganisms to further decompose the remaining organic matter, synthesize more humic acid, vitamins, enzymes and other active substances, and at the same time make the smell of the fertilizer milder.

[0026] In summary, the present invention has the following beneficial effects:

[0027] First, the present invention can improve the fertility of the soil and the growth ability of the root system, so that the orchid can grow normally, thereby avoiding the problems of difficulty in flowering of the orchid and easy root rot;

[0028] Second, the soybean meal, fish meal, bone meal and the like in the present invention are rich in nitrogen, phosphorus, potassium and other macroelements, which can promote the flourishing of Phalaenopsis plants, promote the development of their root systems and enhance the stress resistance of plants, and improve the disease resistance, cold resistance and drought resistance of plants;

[0029] Third, the present invention recycles organic wastes such as soybean meal, peanut shells, corn cobs, sugarcane bagasse, corn stalks, fish viscera, shrimp shells, etc. that might have been discarded, and converts them into high-quality biological fermentation fertilizers, thereby achieving the recycling of resources and reducing the pollution of the environment by waste.
