Description
Technical Field
The invention relates to a microbial selenium-rich pesticide fertilizer for preventing and treating root knot nematode disease, clubroot disease and underground pests, which belongs to the field of pesticides and kills plant diseases and insect pests.
Background
At present, more than 80 kinds of root-knot nematodes are reported internationally, mainly parasitize over 20000 kinds of hosts such as vegetables, fruit trees, economic crops, grain crops, ornamental plants, weeds and the like, plasmodiophora belongs to weak parasitic fungi, namely, the plasmodiophora can survive and infect in many adverse environments, has particularly strong vitality and can survive in soil for more than 10 years.
Clubroot and root knot nematode disease are two major root diseases which are prominent in crop production, particularly vegetable production, and tumors with different sizes are formed at roots to cause root malformation, so that overground parts are finally slow in growth, short, water-deficient, fertilizer-deficient and small and old seedling states. With the progress of the disease, the leaves gradually become withered and yellow, and the death of the whole plant can be caused seriously. Because the two diseases have cross-onset and have a plurality of common parts, the two diseases are often confused by growers in production, and the two diseases cannot be effectively prevented and treated.
The host range is wide, clubroot mostly exists in cruciferae, the life cycle of the first stage can be completed in host plants of non-cruciferae, the quality and yield of vegetables are seriously damaged, the yield is reduced by 25% if the weight is reduced, and the weight is more than 85% if the weight is reduced. The host range of the root knot nematode disease is wider, more than 2000 roots are obtained, and the root knot nematode disease mainly comprises root knot nematode of melon and fruit (javnica) (harmful to tomatoes), root knot nematode of south China (incognita), root knot nematode of north China (hapla), root knot nematode of peanut (arenaria) and the like.
At present, the invention patents related to root-knot nematodes and the invention patents related to root-knot nematodes mostly consider the root-knot nematodes, particularly, the root-knot nematodes and the root-knot nematodes of cruciferous crops are cross-infectious, if the control of the root-knot nematodes is only considered, but the root-knot nematodes and the nutrition of plants are ignored, particularly, the plants are green and environment-friendly, and the later loss is serious, thus seriously threatening the survival and development of human beings.
The invention relates to a drug fertilizer for root-knot nematodes through the search and discovery of invention patents (application No. 201310578539.0), which describes a technical scheme of using chemical fertilizers such as vitamin, seaweed fertilizer, fosthiazate, urea, diammonium phosphate, ammonium sulfate, potassium sulfate and the like, the scheme can undoubtedly increase the production cost of the drug fertilizer, the product only pays attention to the prevention and treatment of the root-knot nematodes, but neglects the treatment of clubroot. The chemical fertilizer is easy to cause soil acidification and hardening after long-term use, has large residual quantity, and does not relate to the addition of beneficial flora for protecting soil.
Currently, biological enrichment and poisoning in China are serious, because pollution of chemical fertilizers and chemical pesticides seriously threatens the survival and development of human beings, people tend to enter various elements of the environment through spreading and applying the chemical fertilizers and the chemical pesticides in crop soil and water areas, and the chemical fertilizers and the chemical pesticides are diffused, adsorbed, operated, absorbed, enriched and the like. The method enters a multi-mode and multi-track operation and circulation and is distributed in all corners of the earth, and the environmental pollution loss caused by chemical fertilizers and chemical pesticides in China is over 95 hundred million, which accounts for over 25 percent of the total pollution loss. The three wastes and the urban garbage in five pollution factories of food (pesticides, fertilizers and the like) have the longest duration, and the residue has the greatest harm to human.
Based on the above problems, the present inventors have considered that there is a need for further improvement of the production formulation of medical fertilizers, which uses various characteristics of beneficial bacterial flora to inhibit harmful bacteria and insects. But also increases the plant nutrition. The present invention is not in conflict with the above-mentioned search patents.

The performance of the raw materials is as follows:
purple lilac spore fungus: the lilac violet spore fungus agent is a novel microorganism live spore preparation, belongs to endoparasitic fungi, is an important natural enemy of some plant parasitic nematodes, can parasitize eggs, can erode larvae and female worms, and can obviously reduce the harm of plant nematode diseases such as root-knot nematodes, cyst nematodes, stem nematodes and the like of various crops. The purple lilac spore fungus can secrete and synthesize various organic acids, enzymes, physiological active substances and the like, the effective components of the purple lilac spore fungus can germinate and generate hyphae invading the nematode eggs and the adult body walls, the components in the nematode body are absorbed to propagate in the nematode body, the normal physiological metabolism of the nematode is damaged, and finally the nematode eggs and the adult are killed. Has the advantages of high efficiency, safety, greenness, no pollution, no residue and the like.
B, bacillus subtilis: the bacillus subtilis can metabolize and secrete bacteriocin (subtilin, polymyxin, nystatin and the like) peptide lipid compounds, organic acid substances and the like in the growth process, the metabolites can effectively inhibit the growth of pathogenic bacteria or dissolve the pathogenic bacteria so as to kill the pathogenic bacteria and have high continuous cropping resistance, and the secreted enzymes of the bacillus subtilis comprise chitinase antimicrobial protein which has strong inhibition effect on various plant pathogenic bacteria (particularly on flagellaria fungi of lower fungi of cruciferous plants and independent plasmodiophora).
The bacillus subtilis forms dominant organisms and groups at the roots of crops, so that the invasion of other pathogenic bacteria is effectively prevented, the nutrition of surrounding bacteria is obtained, and the growth of flagellates and plasmodiophora is inhibited; the bacillus subtilis plays a role in resisting diseases like a vaccine. Secondly, the bacillus subtilis can grow on hyphae of flagellate subtenon fungi and plasmodiophora, pathogenic bacteria are decomposed and consumed, the pathogenic bacteria silk is broken, decomposed cytoplasm is digested, and then the pathogenic bacteria can not further infect plants, so that the effects of bacteriostasis and disease resistance are achieved.
In addition, the bacillus subtilis has two growth periods, namely a spore dormancy period and a reproductive period, can enter the spore dormancy period under unfavorable environments such as severe growth environment, lack of nutrient substances and the like, forms spores which have strong stress resistance and can survive under polar environments such as high temperature, acid and alkali and the like, so that the bacillus subtilis can survive by adapting to the environment, and once the environment becomes suitable for growth, the nutrition is sufficient, the spores automatically enter the reproductive period, and the spores grow into the bacillus subtilis again.
Trichoderma harzianum: is a pure microorganism, a broad-spectrum bactericide, and is prepared by multiple mechanisms of nutrition competition, heavy parasitism, cell wall decomposition enzyme, induction of plant resistance and the like.
Competition effect: the trichoderma harzianum can grow rapidly around the roots of plants, occupies the sites on the surface of the plants, forms a protective cover and prevents pathogenic fungi from contacting the root systems of the plants, so that the root systems of the plants are protected from being infected by pathogenic fungi.
Heavy parasitic action: refers to a complex process of identification of pathogenic bacteria, contact, entanglement, penetration and parasitism in a series of sequential steps. In the interaction process of trichoderma and pathogenic bacteria, host hyphae secrete substances to enable trichoderma to grow towards host fungi, once a host is identified by trichoderma parasites, the trichoderma hyphae grow in a spiral winding mode in parallel with the host hyphae, attached cellular branches are generated and adsorbed on the host hyphae, cell walls are dissolved through secreting extracellular enzymes, the host hyphae penetrate through the host hyphae, nutrition is absorbed, and then the pathogenic bacteria are killed.
The antibiotic action: the trichoderma harzianum can secrete part of antibiotics, can inhibit the growth and colonization of pathogenic bacteria, and can reduce the harm of the pathogenic bacteria.
Plant growth regulation: the trichoderma harzianum colonizes plant root systems and generates compounds for stimulating plant growth and inducing plant defense reaction, so that the microenvironment of the root systems is improved, and the growth vigor and disease resistance of plants are enhanced.
Matrine, and matrine: is a low-toxicity, low-residue and environment-friendly biological pesticide. The matrine is a natural plant pesticide, once the root-knot nematode touches the pesticide, the nerve centre is paralyzed, the protein of the body of the nematode is solidified, the body pore of the nematode is blocked, and the nematode is suffocated and dies.
Abamectin: is a sixteen-membered macrolide compound with insecticidal, acaricidal and nematicidal activities. The action mechanism is to interfere the physiological activity of the nerve, stimulate and release gamma-aminobutyric acid, and after the gamma-aminobutyric acid contacts with the root-knot nematode larvae, paralysis symptoms appear, and the nematode dies after being inactive and does not eat for 2 to 4 hours.
The abamectin is a high-efficiency medicament for killing various parasitic nematodes, has the second characteristic that the abamectin is different from other insecticides in medicinal property and is not easy to generate medicinal property, and has the third characteristic of safety, safety to natural enemies and less pollution to the environment.
Selenium-rich yeast: the selenium content can reach more than 1000 × 10 μ g, usually 500 × 10 μ g, its protein is greater than or equal to 40%, it is rich in 18 amino acids, and vitamin B is 33.2 × 10 μ g. Selenium in the selenium-enriched yeast replaces sulfur in the sulfur-containing amino acid to form seleno-amino acid, and further protein is formed. The biological effect is 10-20 times of that of inorganic selenium, the selenium-enriched yeast can be used as selenium source, and at the same time can provide other beneficial nutrients, it possesses high selenium-enriching capacity and capacity of converting inorganic selenium into organic selenium, and is a natural antidote capable of removing heavy metal accumulation in plant body, and selenium has strong affinity for metal, can be combined with metal to form metal-selenium-protein compound, and has the detoxication action for mercury, cadmium, lead and arsenic, etc. and can be classified according to toxicity and belong to non-toxic substance.
Sugar alcohol complex boron: the sugar alcohol is a good chelating agent for nutrients such as large, medium and trace elements, can be combined with various nutrients to form a stable complex, and is particularly higher in solubility in alkaline solution. Boron is used for preventing and treating clubroot, and different from Ca and PH values, boron can inhibit primary infection of clubroot and secondary infection of clubroot. However, the effects of boron on clubroot are mainly intracellular and therefore do not reduce the number of infected root hairs.
Calcium fulvate: is a high-content organic calcium.
1. Can adjust the pH value of soil and reduce the harm of salt substances and continuous cropping.
2. Can promote the root development of crops.
3. Improving plant immunity, and inhibiting diseases and insect pests. Can effectively control the clubroot, can directly influence the viability of the dormant spores of the clubroot, and can reduce the morbidity degree even if the dormant spores are applied after the clubroot is infected.
4. Ca is the main component of the middle layer of the cell wall, and calcium pectate in the cell wall can improve the resistance of cell wall degrading enzymes.
5. Ca is necessary for membrane structure and ion exchange, so that the cell wall and the membrane structure are stable enough, and the distribution of calmodulin in two flagella is different, thereby causing adverse reaction for changing external Ca environment, further influencing the moving direction of zoospores and inhibiting infection of plasmodiophora to a certain extent.
Amino acids: the compound fertilizer can promote photosynthesis, especially glycine can increase the chlorophyll content in plant, raise the activity of several enzymes, promote Ca absorption and utilization of crop, increase Vc content and sugar content, and has long-acting and fast-acting fertilizer supplementing effect. The polypeptide can improve the immunity of crop roots.
