The invention discloses trichoderma pleuroticola and application thereof. A strain is a trichoderma pleuroticola strain QZ-001H, and the preservation number is CGMCC No.11049. The invention further discloses a biological control preparation comprising the trichoderma pleuroticola strain QZ-001H, and a preparing method thereof. Experiments show that the trichoderma pleuroticola strain has the advantages of being high in growth speed, large in sporulation quantity, wide in action spectrum and high in stress resistance, a large number of plant roots can be colonized fast, and therefore the trichoderma pleuroticola has a good application prospect. The biological control preparation prepared from the trichoderma pleuroticola strain can prevent and control multiple soil-borne plant diseases including one or more of pepper blight, Chinese chestnut shoot blight, pomegranate dry rot and the like, and has an application prospect.

The invention discloses a xinjun'an and propiconazole-containing bactericidal composition. The composition contains xinjun'an and propiconazole which serve as effective components; the weight ratio of the xinjun'an to the propiconazole is (2: 1) to (1: 30); the composition further can contain pesticidally available and acceptable auxiliary materials; the dosage form of the composition can be wettable powder, a suspending agent, missible oil, emulsion in water, water dispersible granules or microemulsion. According to the bactericidal composition disclosed by the invention, the action mechanisms of the effective components are completely different; when compounded, the effective components can act on multiple sites of pathogenic bacteria, so that synergistic interaction is realized, the bacteriocidal spectrum is expanded, the prevention effect is enhanced, the use amount of pesticides is reduced, the generation of the drug resistance is delayed, and the resistance risk is reduced. The bactericidal composition is used for preventing and treating various branch diseases on fruit trees and forests, is particularly suitable for diseases such as apple rot, apple branch ring spot, apple dry rot, cherry bleeding disease, peach tree bleeding disease, blueberry branch rot, walnut branch rot, poplar branch rot and poplar canker disease, and can be further used as a sealing agent for grafting and pruning of the fruit trees and the forests.

The invention relates to the field of agricultural planting, and discloses a method for preventing and controlling dry rot of hickory nuts by fertilization. The method comprises the following steps: 1) broadcasting decay sheep excrement surrounding a hickory nut tree trunk along a crown from November to March of next year; 2) applying dolomite dust and lime to the decay sheep excrement on the portion surrounding a hickory nut tree body by an annular broadcasting method from November to March of next year; 3) after carrying out fermentation treatment on fresh hickory nut hull wastes, broadcasting the fermented fresh hickory nut hull wastes to soil surrounding the hickory nut tree body from November to March of next year, and covering the sheep excrement and the dolomite dust or the lime with the fermented fresh hickory nut hull wastes; and 4) adding water in potassium humate to dissolve the same, and furrowing a shallow ditch in the portion under the periphery of the crown of the walnuttree and applying the potassium humate solution by circulating application. After prevention and control through the method, the disease resistance of hickory nut trees can be improved, dry rot is prevented and controlled effectively, the yield and plumpness of hickory nuts can further be greatly improved, and the empty seed rate of the hickory nuts is reduced.

A preparation method of tulip nutrient fertilizer, which is composed of: Morinda officinalis powder, Atractylodes macrocephala powder, Chuanwu powder, plantain seed powder, peanut cake powder, loofah leaf powder, dried rabbit dung, soybean straw powder, taro leaf powder, Cottonseed husk powder, plant ash powder, bone meal, milk powder, pine needle powder, licorice powder, sesame cake powder, brown sugar powder, onion powder, tea dry powder, the percentages described are percentages by weight; effectively overcome the need for segmented fertilization of tulips And multiple times of fertilization, pesticide application and low yield of tulip flower buds, less economic value, leaves withered, falling off, less flowering, small flower buds, small and underdeveloped roots, slow growth, and more likely to cause various diseases and insect pests and wither and die. .

The invention discloses a veratrine plant source compound bactericide and application thereof. The veratrine plant source compound bactericide is prepared from the following raw materials in percentage by weight: 0.1 to 10 percent of veratrine, 1 to 20 percent of a willow bark extract and the balance of auxiliaries, wherein the veratrine is a total veratrine-containing pure product, a mixture or a veratrum plant extract. The veratrine plant source compound bactericide is microemulsion, water aqua or wettable powder. The bactericide disclosed by the invention does not contain any chemical pesticidal components, easily degrades in an environment, and is safe to human, livestock and the environment; pathogenic bacteria cannot resist the veratrine plant source compound bactericide; meanwhile, the veratrine plant source compound bactericide has the advantages of high stability, high efficiency and low cost. The bactericide can be used for preventing and treating one or more of diseases of crops, such as brown rot, gray mold, soft rot, pear scab, bacterial shot hole, downy mildew, phytophthora root rot, powdery mildew, late blight and dry rot, and also used for preventing and treating other plant diseases.

The invention discloses an anti-dry rot hickory nursery stock grafting cultivation method. According to the method, hickory susceptible to dry rot is used as the scion, and strawberry type Hunan hickory is used as the stock. The hickory nursery stock obtained through grafting cultivation with the method is capable of resisting dry rot, the morbidity of dry rot is near zero, pesticides for resisting dry rot are not needed basically, and in this way, planting cost is reduced, economic benefits are improved, and improvement of drug resistance of pathogenic bacteria and the influence of bactericides on the environment caused by excessive application of bactericides can also be avoided.
