Description

Technical Field

[0001] The invention belongs to the technical field of pesticide fertilizers, and in particular relates to an African bean slurry liquid insecticide organic pesticide fertilizer and a preparation process thereof. Background Art

[0002] Frequent use of traditional pesticides can lead to pesticide residues, which are harmful to human health and the environment; excessive fertilizer application can lead to environmental problems such as soil pollution and groundwater pollution, and can also reduce soil fertility; the single functionality of traditional pesticides and chemical fertilizers makes it easy for crops to develop resistance and dependence. Therefore, the emergence of organic fertilizers solves the problems of traditional pesticides and chemical fertilizers, and achieves high efficiency, environmental protection and safety in agricultural production by developing products with the dual functions of pest control and plant growth promotion. Organic fertilizers can reduce the use of chemical fertilizers and pesticides to a certain extent, increase crop yields and quality, and reduce negative impacts on the environment.

[0003] Mixing drugs and fertilizers is prone to compatibility problems, effectiveness problems on the target and product quality stability problems. The types and proportions of drug-fertilizer ratios also need to take into account the surrounding environment and climatic conditions to avoid environmental factors weakening the integrated effect of drugs and fertilizers or even causing drug damage or fertilizer pollution. Most drug-fertilizer products on the market are in the form of granules or powders, and liquid drug-fertilizers are rare, so the scope of use of drug-fertilizers is limited.

[0004] Therefore, how to provide a liquid insecticidal organic fertilizer that is simple to prepare and use and has significant insecticidal and fertilizer-increasing effects is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the purpose of the present invention is to overcome the problems of pest management, pesticide residues, fertilizer usage, crop yield and quality existing in the application of existing traditional pesticides and fertilizers, and to provide an African bean slurry liquid insecticide organic fertilizer and a preparation process thereof to solve the technical problems of environmental pollution and drug residues caused by the application of existing pesticides and fertilizers.

[0006] It should be noted that pesticide fertilizers can integrate fertilization and prevention, reduce the number of fertilization and pesticide applications, simplify agricultural production management, and improve work efficiency. When applying pesticide fertilizers, plants can absorb nutrients and pesticides at the same time, which helps to effectively utilize resources and reduce the waste of fertilizers and pesticides. Through the pesticide ingredients contained in insecticide source plants, organic biological pesticide fertilizers can reduce the frequency of use of chemical pesticides, reduce environmental pollution and continuously improve the safety of agricultural products. African bean biogas liquid insecticide organic fertilizer uses natural ingredients, which is more in line with the needs of sustainable agricultural development and helps achieve green planting goals.

[0007] In addition, in the present invention, by fermenting African edamame containing the insecticide active ingredient rotenone with biogas slurry to form liquid fertilizer, there is no need to consider the compatibility of pesticides and fertilizers, and the product is more stable; and the application scope of the fertilizer is expanded, and it can control ground pests by spraying, and can also control underground pests by a drip irrigation system.

[0008] Furthermore, the pesticide component prepared from the African yam in the present invention is a plant-based pesticide, which is completely degraded in the environment, has no residue, and has little environmental pollution; at the same time, the African yam can also be used as a green manure plant to improve soil fertility.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] The first technical purpose of the present invention is to provide an African edamame biogas slurry liquid insecticide organic fertilizer, comprising biogas slurry, African edamame, microbial flora, a water-soluble isolating agent and a plant growth regulator; the weight proportions of each substance are: 250-500 parts of biogas slurry, 100-300 parts of African edamame dry powder, 15-20 parts of microbial flora, 1-3 parts of water-soluble isolating agent, 0.05-0.5 parts of plant growth regulator and 50-100 parts of water.

[0011] Optionally, 350-450 parts of biogas slurry, 150-250 parts of African bean dry powder, 17-18 parts of microbial flora, 1.5-2.5 parts of water-soluble isolation agent, 0.15-0.3 parts of plant growth regulator, and 70-80 parts of water.

[0012] Optionally, the African edamame is obtained by fermenting and extracting mature African edamame plant dry powder.

[0013] The second technical purpose of the present invention is to provide a preparation process of the African bean slurry liquid insecticide organic fertilizer as described above, comprising the following steps:

[0014] The harvested mature African edamame plants are dried and crushed, and then added into biogas slurry together with microbial flora, plant growth regulators and water-soluble isolating agents. The plants are shaken and soaked in the biogas slurry for 10-15 days by ultrasonic wave to obtain African edamame biogas slurry liquid insecticide organic fertilizer.

[0015] Optionally, the microbial flora used is nitrogen-fixing bacteria and Bacillus.

[0016] Optionally, the nitrogen-fixing bacteria used are autotrophic nitrogen-fixing bacteria, and the Bacillus species are Bacillus amyloliquefaciens and Bacillus subtilis.

[0017] Optionally, the plant growth regulator used is one or a mixture of brassinolide, indoleacetic acid, cytokinin, gibberellin, and ethephon.

[0018] Optionally, the water-soluble release agent used is silicone oil, surfactant and calcium carbonate.

[0019] Optionally, the surfactant used is one of sodium dodecyl sulfate, dodecyl glucoside, and isomeric alcohol polyoxyethylene ether.

[0020] Furthermore, the African edamame biogas slurry liquid insecticide organic fertilizer is diluted with water at a ratio of 1:20 for spraying on plant leaves, and the plant is preferably corn.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) The present invention uses a large amount of cheap and easily available biogas slurry and African edamame with excellent insecticidal activity as raw materials. The prepared biological fertilizer contains not only nitrogen, phosphorus, potassium fertilizer and other mineral elements necessary for the growth of various crops, but also rich isoflavone compounds, and three exogenously added nitrogen-fixing bacteria, amyloliquefaciens and Bacillus subtilis, which can increase the yield of conventional crops and have significant control effects on diseases and insect pests. The prepared biological fertilizer has clearer functions, stronger targeting and more significant effects.

[0023] 2) Edamame is rich in isoflavone compounds, including a large amount of rotenone and rotenoids, which have excellent insecticidal activity; Bacillus can secrete a variety of antibacterial substances in the state of pure liquid culture. Experiments have shown that rotenone and rotenoids have good insecticidal effects on common crop pests such as aphids and planthoppers; microbial agents prepared by Bacillus have a strong growth inhibitory effect on common pathogens of crops such as large / small spot disease, stem base rot, and sheath blight.

Other improvements made by those skilled in the art based on the above invention content without inventive work are also considered to fall within the scope of protection of the present invention.

[0092] Comparative Example 1:

[0093] This embodiment adopts a treatment method without applying any fertilizers and pesticides, and watering is applied normally. Other field management measures remain consistent in each embodiment and are uniformly implemented in accordance with local conventional corn production management.

[0094] The pesticide was applied three times during the entire growth period of corn, and 7 days after each application, the control effect of corn aphids in each treatment was investigated. At maturity, the agronomic traits of corn in each example, such as ear length, bald tip length, and ear diameter, were measured; each example was harvested separately and the 100-grain weight and yield were measured.

[0095] As shown in Table 1, 7 days after the first application, the field control effect of corn aphids in different embodiments was 67.5-88.7%; 7 days after the second application, the field control effect of corn aphids in different embodiments was 72.8-93.3%; 7 days after the third application, the field control effect of corn aphids in different embodiments was 77.2-96.8%. The pest control effect of corn in all treatment groups was better than that of the control group, among which Example 9 had the highest control effect.

[0096] As can be seen from Table 2, different organic fertilizer products have a certain degree of improvement in ear length, bald tip length, ear thickness, 100-grain weight, yield, etc. compared with the control treatment. Among them, Example 6 increased production by 26.7% compared with CK, with a significant impact. Different organic fertilizer products have a significant impact on corn aphid control, corn yield and related traits. Considering agronomic traits, economic benefits, environmental protection and other factors, the African bean slurry liquid insecticide organic fertilizer in the present invention has obvious advantages in agricultural production.
