Description

Technical Field

[0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic fertilizer for activating soil and increasing peanut yield, and a preparation method thereof. Background Art

[0002] Fertilizers that use organic matter (compounds containing carbon) are called organic fertilizers, including human feces, manure, compost, green manure, cake fertilizer, biogas fertilizer, etc. The nutrients contained in organic fertilizers are mostly in organic state. Through the action of microorganisms, they slowly release a variety of nutrients, continuously supplying nutrients to crops. They have the characteristics of many types, wide sources, and long fertilizer effects. The application of organic fertilizers can improve soil structure, coordinate water, fertilizer, gas, and heat in the soil, and improve soil fertility and land productivity.

[0003] In the process of peanut cultivation, in order to increase the yield of peanuts, it is necessary to apply organic fertilizers. Traditional organic fertilizers are mostly made by fermenting feces, straw, etc. After applying organic fertilizers, the corresponding nitrogen, phosphorus and potassium fertilizers are added later to increase the peanut yield. However, this method not only requires multiple fertilizations, but also relies solely on one type of organic fertilizer. The activation effect of the soil is poor. The subsequent additional fertilization may cause the soil to become compacted again. At the same time, traditional organic fertilizers have a strong odor during the fermentation process, which will affect the environment, so this needs to be improved. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an organic fertilizer for activating soil and increasing peanut yield and a preparation method thereof, which has the advantage of promoting soil activation.

DETAILED DESCRIPTION

[0037] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0038] The embodiment of the present invention provides an organic fertilizer for soil activation and improving peanut yield, comprising the following ingredients: peanut bran liquid fertilizer, active humic acid, quick-acting fertilizer, molybdenum fertilizer, potassium dihydrogen phosphate, boron fertilizer and calcium fertilizer, wherein the weight percentage is:

[0039] Peanut bran water fertilizer: 10-20%;

[0040] Active humic acid: 2-5%;

[0041] Quick-acting fertilizer: 15-25%;

[0042] Molybdenum fertilizer: 0.01-0.1%;

[0043] Potassium dihydrogen phosphate: 0.3%;

[0044] Boron fertilizer: 0.1-0.15%;

[0045] Calcium fertilizer: 0.1%.

[0046] The invention uses peanut bran liquid fertilizer as the main organic fertilizer, which can increase the fertilizer effect duration, improve the physical and chemical properties of the soil, increase the number of microorganisms beneficial to the growth of the root system, change the soil compaction condition, and promote soil activation; the active humic acid as the secondary organic fertilizer can form a complex with the nutrient ions in the organic fertilizer, improve the slow-release effect of the organic fertilizer, prevent the premature aging of crops, and also increase the activity of microorganisms in the soil, making the soil loose and breathable, and retaining water and fertilizer; the quick-acting fertilizer can provide sufficient nitrogen, phosphorus and potassium for the growth of peanuts, and ensure the nutritional supply of peanuts; the molybdenum in the molybdenum fertilizer can increase the number of peanut nodules, shorten the nodule formation time, and promote the flowering and absorption of peanut seedlings. The invention can improve the peanut kernel rate and increase the yield potential, while potassium dihydrogen phosphate can protect roots and leaves, promote fruit expansion, improve fruit setting rate and fullness, and can also greatly promote the transfer of photosynthetic products and extend the peanut harvest period. Boron fertilizer can promote pollen germination, which is beneficial to pollination and fertilization, improve fruit setting rate, increase chlorophyll content, and enhance photosynthesis. The calcium in calcium fertilizer can promote the formation of new roots and young roots of peanuts, promote the development of the root system, and enhance the light transmittance, lodging resistance and disease resistance of the group. The present invention starts with improving soil activation and peanut yield, thereby improving the release of organic matter, providing a good environment for the growth of peanuts, and improving the quality of peanuts.

[0047] Among them, the quick-acting fertilizer is composed of phosphate fertilizer: calcium magnesium phosphate fertilizer, potassium fertilizer: potassium sulfate and nitrogen fertilizer: urea, among which phosphate fertilizer, potassium fertilizer and nitrogen fertilizer are mixed in a ratio of 3:1:2.

[0048] Commonly used ammonium chloride, potassium chloride, and superphosphate will increase the acidity of the soil after fertilization. Phosphorus fertilizer should be replaced with calcium magnesium phosphate fertilizer, potassium fertilizer should be replaced with potassium sulfate, and nitrogen fertilizer should be replaced with urea. This can adjust the pH value of the soil and prevent the soil from being too acidic and affecting the absorption of molybdenum in molybdenum fertilizer.

[0049] Among them, molybdenum fertilizer uses ammonium molybdate, which is bluish white crystal or powder, soluble in water, and contains 54% molybdenum.

[0050] Insoluble molybdenum is ineffective on crops. The use of water-soluble ammonium molybdate is conducive to mixing with organic fertilizers, which promotes the absorption of molybdenum by peanuts. At the same time, the dosage of molybdenum fertilizer needs to be strictly controlled when applying it. The effect is most significant when applying in trace amounts. Excessive application can easily cause heavy metal molybdenum to pollute peanuts and the environment.

[0051] Among them, the boron fertilizer uses fluid boron, which is an organic boron fertilizer with a viscous appearance, a weakly alkaline pH value, and is easily soluble in water.

[0052] Fluid boron can be mixed with water in any proportion to solve the problem of boron fixation in the phloem and leaching in the soil. Fluid boron can quickly penetrate the waxy layer of plant epidermis and be absorbed by crops. It has good miscibility and promotes calcium absorption by peanuts.

[0053] Among them, calcium fertilizer uses organic chelated calcium. The organic chelated calcium aqueous solution is neutral and can be mixed with a variety of foliar fertilizers.

[0054] As a liquid calcium fertilizer, organic chelated calcium has good water dispersibility, does not contain chlorides and harmful substances, and does not harm crop leaves and fruit surfaces. It also contains surfactants with super spreading properties, which can greatly improve the efficiency of calcium absorption by leaves and fruit surfaces, and can significantly prevent and treat diseases caused by calcium deficiency in crops, increase yields, and improve quality.

[0055] The embodiment of the present invention provides a method for preparing an organic fertilizer for soil activation and increasing peanut yield, and the specific steps are as follows:

[0056] Step 1: Raw material preparation

[0057] Prepare sufficient peanut bran cakes, molasses and water in good condition, then put the peanut bran cakes into a grinder for full grinding, and obtain peanut bran crumbs after 30 minutes, and then observe whether there are foreign matters in the molasses, and if there are foreign matters, remove them from the molasses;

[0058] Step 2: Crushing raw materials

[0059] Put the crushed peanut bran into a sieving machine for sieving to remove large impurities in the crushed peanut bran, thereby obtaining a peanut bran raw material with uniform texture and uniform particle size;

[0060] Step 3: Mixing the ingredients

[0061] Add molasses, peanut bran and water in a mixing tank in a ratio of 1:3:15 and stir and mix. After stirring for thirty minutes, a mixture raw material can be obtained.

[0062] Step 4: Fermentation of raw materials

[0063] The mixed raw material is placed in a fermentation tank, and a fermentation agent is added to the fermentation tank for auxiliary fermentation, and then the fermentation tank is heated at a constant temperature to maintain the fermentation tank at a constant temperature, and the fermentation tank is opened every two days during the fermentation process, and air is introduced into the fermentation tank;

[0064] Step 5: Check the fermentation progress

[0065] After 15-20 days of fermentation in the fermentation tank, check the color, state and smell of the stock solution in the fermentation tank to see if it is dark red, pasty, or has a bad smell. If all indicators are normal, the fermentation is complete. If the fermentation is unqualified, continue the fermentation until the fermentation is complete and the fermentation is mature.

[0066] Step 6: Residue Filtering

[0067] Pour the fermented liquid into the filter for filtering. After the first filtering, replace the filter with a smaller gap for secondary filtering. Repeat this operation until the remaining bran residue and impurities in the liquid are removed, thereby obtaining pure peanut bran liquid fertilizer.

[0068] Step 7: Finished product production

[0069] Prepare one portion each of peanut bran liquid fertilizer 10-20%, active humic acid 2-5%, quick-acting fertilizer 15-25%, ammonium molybdate 0.01-0.1%, potassium dihydrogen phosphate 0.3%, fluid boron 0.1-0.15% and organic chelated calcium 0.1% according to weight percentage, then put the raw materials of each component into a stirring tank and add clean water to fully stir, and after stirring until the raw materials of each component are completely dissolved and mixed, a finished organic fertilizer product can be obtained.

[0070] The invention can obtain pure peanut bran liquid fertilizer by mixing and fermenting peanut bran and molasses, and can obtain finished organic fertilizer by mixing the peanut bran liquid fertilizer with active humic acid, quick-acting fertilizer, ammonium molybdate, potassium dihydrogen phosphate, fluid boron and organic chelated calcium. The preparation method of the invention is simple and convenient to operate, does not require composting operation, does not require the addition of animal feces, has no odor during the fermentation process, and does not cause environmental pollution.

[0071] The fermentation agent in step 4 is a mixed fermentation bacterial liquid made of Bacillus licheniformis, Bacillus subtilis and Trichoderma viride, and the added weight percentage is 5-8%.

[0072] By adding mixed fermentation bacteria liquid, it is helpful to increase the fermentation rate, promote the decomposition of molasses and peanut bran, and prevent root burn caused by incomplete fermentation after fertilization.

[0073] The fermentation temperature in step 4 is controlled between 30°C and 40°C, while avoiding large fluctuations in the temperature in the fermentation tank.

[0074] Constantly controlling the fermentation temperature is beneficial to providing a stable growth environment for the bacteria during the fermentation process, which is more conducive to the fermentation and decomposition of the bacteria.

[0075] During the fermentation process in step 4, stirring is performed every two days, and the stirring time is controlled within 5-10 minutes.

[0076] Regularly stirring the stock solution in the fermentation tank can make the stock solution and the starter mix more fully, thereby improving the fermentation rate and quality.
