Description
Technical Field
The invention relates to the technical field of biofertilizers, and particularly relates to a biofertilizer for litchi planting and a preparation method thereof.
Background
It is recognized in the art that chemical fertilizers have an important effect on crop production. However, at present, the utilization rate of the chemical fertilizer is less than 30%, the rest of the chemical fertilizer is lost along with the water and the soil, and the application of the chemical fertilizer not only causes great waste, but also pollutes the soil and underground water resources. In order to improve the environment, it is imperative to provide a pollution-free fertilizer.
The biological fertilizer is a product which can make crops obtain specific fertilizer effect by means of microbial life activity. The biological fertilizer can improve soil fertility, which is the main function of the biological fertilizer, such as various nitrogen-fixing bacteria fertilizers, and can increase nitrogen sources in soil; the phosphate-and potassium-solubilizing bacterium fertilizer can dissolve insoluble phosphorus and potassium in soil, and increase the sources of phosphorus (P) and potassium (K) elements in the soil; the actinomycete biological fertilizer not only has the function of antagonizing pathogenic bacteria to prevent diseases and strengthen bacteria, but also can secrete cytokinin to promote the growth of crops; the fungus biological fertilizer not only has strong function in assisting crops to absorb mineral elements such as phosphorus, zinc, copper and the like, but also has the functions of enhancing the water absorption and water retention of the crops to improve the drought resistance of the crops. In addition, the biological fertilizer can promote the growth of crops and improve the quality of agricultural products, and when various biological fertilizers are applied to soil, different growth hormones can be generated to stimulate the growth of the crops. The biological fertilizer can produce and assist crops to absorb and utilize various nutrient elements, so that the biological fertilizer has a great improvement effect on the quality of agricultural products, and all indexes of the agricultural products reach the standard of green food.
Although biofertilizers can be used for crop cultivation and are not harmful, limited yield increase remains an important factor limiting their widespread use. How to improve the yield-increasing effect of the biological fertilizer is a subject to be researched by the technicians in the field.
Disclosure of Invention
The invention aims to provide a bio-fertilizer for litchi planting and a preparation method thereof. According to the invention, the soybean meal powder, the bacillus subtilis, the bacillus licheniformis, the silicate bacteria, the diatom, the soil loosening agent and the methionine are organically combined, so that the combined biological fertilizer for litchi planting can not only improve the litchi yield, but also improve the litchi pulp quality.
In order to achieve the purpose, the invention provides the following technical scheme:
the invention adopts one of the technical schemes: the bio-fertilizer for litchi planting comprises the following components in parts by weight: 8 to 12 portions of soybean meal, 0.05 to 0.2 portion of bacillus subtilis, 0.2 to 0.4 portion of bacillus licheniformis, 0.15 to 0.25 portion of silicate bacteria, 0.5 to 0.8 portion of diatom, 0.1 to 1 portion of scarifier and 0.08 to 0.12 portion of methionine.
The biological fertilizer for litchi planting disclosed by the invention has the main component of soybean meal, is high in protein content of the soybean meal, and can provide sufficient nutritional ingredients for microorganisms in the biological fertilizer for litchi planting so as to enable the microorganisms to quickly proliferate.
The bacillus subtilis added in the bio-fertilizer for planting litchi can decompose organic matters in soil, so that effective nutrients in the soil are increased, the soil structure is improved, meanwhile, active substances such as subtilin, polymyxin and nystatin can be generated in the bacillus subtilis propagation process, the propagation of harmful microorganisms is inhibited, in addition, hormone substances and various vitamins can be generated in the bacillus subtilis propagation process, and the growth of litchi is promoted. The action of the added bacillus licheniformis is similar to that of the bacillus subtilis, and the bacillus licheniformis and the bacillus subtilis can have a wider antibacterial range by matching. The silicate bacteria added in the invention are used as the dominant flora in soil, and metabolism can generate organic acid substances, so that the propagation of harmful bacteria is inhibited, silicate minerals can be eroded, and not only can major elements of potassium and phosphorus in soil be activated, but also trace elements such as iron, manganese, molybdenum, boron and the like can be activated; in addition, silicate bacteria can provide silicate required for growth for diatom by corroding silicate minerals so that the diatom can be fixedly planted in soil, the nitrogen fixation effect of the diatom can participate in the nitrification and denitrification cycle of litchi root systems to promote the absorption of nitrogen by the litchi root systems, and meanwhile, the diatom in the superficial layer of the ground surface can synthesize organic matters through photosynthesis to increase the soil fertility; the potassium element rich in the thallus of the silicate bacteria can be released after the silicate bacteria die and is absorbed by the root system of the litchi. The soil loosening agent added in the invention can loosen soil, is convenient for the propagation of various microorganisms and diatoms, and the added methionine can inhibit the excessive growth of branches and leaves of litchis, so that more nutrients are transferred to fruits, and the yield of litchis is promoted to be increased. Meanwhile, microorganisms in the biological fertilizer for litchi planting can generate various nutrients, so that the litchi yield can be increased, and the litchi quality can be improved.
The biological fertilizer for litchi planting provided by the invention can be applied independently, and can also be applied together with a base fertilizer.
Preferably, the silicate bacteria are bacillus mucilaginosus.
Preferably, the diatom is navicula.
Preferably, the navicula comprise: round navicula, cuspid navicula, navicula dicoccus or navicula binorum.
The navicula algae selected by the invention can be fixedly planted in soil, not only can fix nitrogen, but also can form organic matters through photosynthesis to increase soil fertility.
Preferably, the scarifier is polyacrylamide.
The invention selects polyacrylamide as the soil loosening agent, so that the prepared biological fertilizer for litchi planting consists of fully degradable components and does not contain any component which may have chemical residue.
The technical scheme of the invention is as follows: the preparation method of the bio-fertilizer for litchi planting is provided, and comprises the following steps: drying, crushing and sieving the soybean meal to prepare soybean meal powder, weighing the soybean meal powder, bacillus subtilis, bacillus licheniformis, silicate bacteria, diatom, a soil loosener and methionine according to the weight parts, and uniformly mixing to prepare the bio-fertilizer for litchi planting.
Preferably, the drying is drying the soybean meal to a water content of not more than 8wt.%.
The soybean meal is controlled to be below 8 wt%, because the high water content of the soybean meal is not beneficial to the preservation of the prepared bio-fertilizer for litchi planting.
Preferably, the sieving is through a 20 mesh sieve.
The selected soybean meal powder is the soybean meal powder which is sieved by a 20-mesh sieve, and the reason is that the soybean meal powder particles are too large to be beneficial to the utilization of microorganisms after application, and the proliferation speed of the microorganisms is influenced.
The invention has the following beneficial technical effects:
the invention discloses a bio-fertilizer for litchi planting, which comprises soybean meal, bacillus subtilis, bacillus licheniformis, silicate bacteria, diatom, a soil loosening agent and methionine. According to the invention, through organic combination of various raw materials, the combined biological fertilizer for litchi planting can not only improve the litchi yield, but also improve the litchi pulp quality.
The raw materials used in the invention are all common raw materials in the field, and the preparation method is simple, is suitable for mass production and has great popularization and application values.
