The invention also discloses the thick-shell mussel fat-soluble extract prepared according to the method, which is an antiphlogistic active substance containing various unsaturated fatty acids; the thick-shell mussel fat-soluble extract can be used for preparing antiphlogistic enteropathy medicines or health-care foods.

The invention belongs to the technical field of medicines and relates to a preparation method of paliperidone palmitate. The method disclosed by the invention comprises the step of precipitating paliperidone palmitate in a mixed solvent of dichloromethane and n-heptane. Paliperidone palmitate particles obtained by the invention are small in particle sizes, flaky, easy to homogenize and grind, andshort in grinding time, have little damage to instruments and equipments, and are short in crystallization time, high in yield and free of solvent residues and particularly suitable for needs of industrial production.

The invention relates to a crop gray mold prevention and treatment agent, which takes an extract of a leaf of cattail as a raw material. The extract comprises a preservative. According to the agent, the leaf of the cattail is taken as the raw material; the extract can be obtained by decocting or juicing, then is sprayed onto crops after diluted with water, and can exert a prevention function when the crops are not attacked, and exert a good treatment function when the crops are attacked; a cure rate reaches 100% according to a field test; the agent not only can prevent and treat gray mold, but also has an obvious preventive effect on other fungus diseases; and in addition, the leaf of the cattail is a wild vegetable, and can be eaten, so that the problem of pesticide residue cannot occur in actual use.

The invention discloses a printed matter die cutting device which comprises a machine box and foot pads, wherein one foot pad is arranged on each of the left side and the right side of the lower end of the machine box, the machine box is fixedly connected with the foot pads through bolts, a controller is arranged on the right side of the front end of the machine box and electrically connected with a power source, and a transmission mechanism is arranged at the right end in the machine box. For the printed matter die cutting device disclosed by the invention, by changing a traditional manual adjustment mode into an existing mode of connection transmission through a lead screw and a sleeve, in this way, adjustment can be more convenient and faster, and different heights of the two sides cannot occur during adjustment. When the printed matter die cutting device is used for cleaning, at this time, a second motor rotates to drive the lead screw to rotate and can rotate forwards and backwards, so that the sleeve can move up and down, a bracket can be driven to move, a cleaning roller can move, the left end and the right end of the cleaning roller are the same in elevation, cleaning can be more thorough, and residues are avoided.

The invention discloses an array substrate, a manufacturing method and a display device of an organic electroluminescent display panel. According to the manufacturing method of the array substrate, after a first photosensitive organic layer is formed, prebaking treatment is carried out on the first photosensitive organic layer, a solvent in the first photosensitive organic layer is removed, and therefore adhesion between the first photosensitive organic layer and a film layer where a pixel electrode is located is enhanced, and photonasty of the first photosensitive organic layer is reduced; then, a second photosensitive organic layer is formed on the first photosensitive organic layer, and the composition technology is carried out on the second photosensitive organic layer to form a spacer graph, and the first photosensitive organic layer cannot be affected; the composition technology is carried out on the first photosensitive organic layer to form a pixel limit layer graph, and primary curing treatment is carried out on the spacer graph and the pixel limit layer graph. Therefore primary curing treatment can be omitted, so that the manufacturing technology of a spacer and the pixel limit layer is simplified. The problem that organic material residues cannot exist is solved.

The invention belongs to the technical field of prevention and treatment of plant diseases and pests, and particularly relates to a method for preventing and treating the kadsura coccinea leaf blightdisease. The method specifically comprises the following step: spraying traditional Chinese medicinal liquid at the early onset once a day, wherein the spraying amount for each plant is 50 to 100 ml.The traditional Chinese medicinal liquid is prepared from the following raw materials in parts by weight: 20 to 50 parts of fructus cnidii, 10 to 40 parts of calamine, 5 to 20 parts of pericarpium granati, 3 to 16 parts of oldenlandia diffusa and 1 to 6 parts of folium ilicis purpurea. By the use of the method disclosed by the invention, during prevention and treatment of the leaf blight disease,and the problem of remaining of harmful substances is solved; furthermore, the method is efficient, green, environmentally friendly and pollution-free.

The invention provides a pest control method for plantation of crops. A liquid medicine which is used concretely comprises the following raw materials in parts by weight: 10-20 parts of chilli powder, and 1-10 parts of lemonade whose mass concentration is 30%; the control method comprises the following steps: (1) the liquid medicine is prepared into a spraying agent; (2) during prevention, the liquid medicine is sprayed one time a day, and 7 days of continuous spraying is regarded as a period; (3) during treatment, spraying is carried out 2-3 times a day, and 7-10 days of continuous spraying is regarded as a period. The method has the following beneficial effects: crops are sprayed, the method can play a prevention effect before crops are invaded, and the method can play a good treatment effect after crops are invaded; during on-site tests, the cure rate of diseases due to aphids reaches 95%; except control of aphids, the method has obvious preventing, expelling and treating effects for piercing-sucking insect pests, such as Tetranychus cinnbarinus, leaf eating insects, fleas, and mosquitoes without drug residue problems in actual use.

The invention belongs to the technical field of pest control, and discloses a method for controlling crop pests by using camellia oleifera shells, which comprises the following steps: obtaining camellia oleifera shells, removing impurities from the camellia oleifera shells, and drying; the dried camellia oleifera shells are pretreated; extracting the pretreated camellia oleifera shells to obtain a camellia oleifera shell extracting solution; preparing a crop pest control agent from the obtained camellia oleifera shell extracting solution, tripterygium wilfordii, dandelion, a biological organic fertilizer, a biological agent and amino-oligosaccharin; the prepared crop pest control agent is mixed with wood vinegar and water in proportion and then applied to soil, and deep ploughing is carried out. Natural plants or Chinese herbal medicines such as camellia oleifera shells and tripterygium wilfordii are used for preparing the crop pest control agent, pest control can be effectively carried out, and the control effect is good; meanwhile, the problem of pesticide residues is avoided, and the drug resistance of diseases and pests is not enhanced.
