The invention discloses a nutritional-type fertilizer. The fertilizer is prepared from following raw materials in parts by weight: 35-40 of gypsum, 25-30 of bentonite, 13-16 of diammonium phosphate, 10-13 of potassium fulvate, 1-2 of ammonium molybdate, 1-3 of copper sulfate, 1-2 of ferrous sulfate, 3-4 of boric acid, 2-3 of polyvinyl alcohol, 4-6 of chitosan, 3-7 of sodium alginate, 8-12 of a soil conditioner and a proper amount of water. The fertilizer adopts the potassium fulvate and plant essential nutrient elements as components. The ratio of the plant nutrients is reasonable. The fertilizer has characteristics of capability of allowing premature ripening and preventing premature senility for grain crops, vegetables, fruits and economic crops. The fertilizer prepared from the chitosan and the boric acid not only is capable of killing pests, preventing diseases for plants and functioning as a fertilizer, but also is capable of decomposing animal and plant residual bodies and trace metal elements, thus converting the residual bodies and the trace metal elements into nutrients for the plants, enhancing plant immunity and promoting plant health. The bentonite has strong moisture adsorption capability, and can absorb water having a volume of 8-20 times of the volume of the bentonite itself and swell to 30 times in volume. The bentonite has certain glutinousness, thixotropy and lubricity. The blend of the bentonite and silt has plasticity and caking property, and has strong cation exchange capability and adsorption capability.

The invention relates to penicillium protein elicitor EPTP and application thereof in improving plant disease resistance. The protein sequence of the EPTP protein elicitor is shown as SEQ ID NO.2, and the molecular weight is 19247 Da. EPTP induces significant increase of activity of phenylalanine ammonialyase, peroxidase and polyphenol oxidase, and when the elicitor induces tobacco anaphylactic reaction, an anaphylactic reaction marker gene hin1 is induced to express; it is indicated through semiquantitative RT-PCR results that EPTP can induce tobacco to obtain systemic acquired resistance, cause up-regulation of the tobacco blade resistance gene transcription level, and induce expression of resistance gene related to the salicylic acid path and the jasmonic acid path. After being applied, EPTP can improve resistance to viruses and pathogenic bacteria by plants, takes effects efficiently, does not pollute environment, reduces dosage of chemical pesticide and has wide application prospects as a plant immunity activator.

The invention discloses a microorganism fertilizer for promoting crop growth and a preparation method therefor. The microorganism fertilizer comprises the components in parts by weight: 100 parts of plant stalks, 0.08-0.16 part of 5A-hydroxyl laxogenin, 0.04-0.10 part of theobromine, 60-80 parts of chitosan hydrochloride, 0.8-1.2 parts of bacillus subtilis bacterium, 6-10 parts of lactobacillus powder, 4-8 parts of yeast powder, 8-20 parts of potassium dihydrogen phosphate, 6-10 parts of ferrous sulfate, 10-15 parts of calcium carbonate, 1-3 parts of magnesium chloride, 1-3 parts of molybdate, 1-3 parts of zinc sulfate, 1-3 parts of manganese sulfate and 1-3 parts of boric acid. The microorganism fertilizer disclosed by the invention comprises 5A-hydroxyl laxogenin and theobromine, the two components have mechanisms that promote growth, and compound use of the two components can further play synergy, so that the crop growth is significantly improved. In addition, after the chitosan hydrochloride is dissolved into soil, animal and plant residues and trace metal elements are decomposed, thereby transforming into nutrients of plants, improving plant immunity, and promoting plant health.

The invention provides a method and a reagent set for preventing citrusyellowshoot, and belongs to the field of agricultural plant cultivation. The technical scheme is that the method for preventing citrusyellowshoot comprises the following steps: A, applying quick lime to soil of a citrus orchard according to usage amount of 50-150 kg / mu; B, applying organic fertilizer containing microorganism bacteria to the soil of the citrus orchard according to usage amount of 100-250 kg / mu; C, every 30-40 days, spraying a plant immunity inducer on citrus plants or irrigating the plant immunity inducer on roots, usage dosage being 100-150 g / mu, and continuously using 3-5 times. The quick lime is used to adjust soil acidity, and an organic biological bacterial fertilizer is used in a cooperated manner, to improve soil structure and quality. The biological bacteria is cooperated with the plant immunity inducer to promote root activity of the citrus plants, improve citrus disease resistance, so as to efficiently prevent citrusyellowshoot in a green manner, and promote healthy growth of the citrus plants.

The new type of environment protecting biochemical fertilizer can raise plant's immunity, promote plant growth, improve soil and reduce pollution to soil. The environment protecting biochemical fertilizer contains diatomite, microbe colony, one or several azophoska components, and plant immunity promoter. The fertilizer may be compounded based on different soil environment and different plant growth condition, so as to make full use of the fertilizer.

The invention relates to the technical field of plant genetic engineering, and specifically relates to application of a gene GmLMM1 related to soybean phytophthora resistance. According to the presentinvention, the gene GmLMM1 involved in the regulation of soybean cell death, immune response and phytophthora resistance is cloned in soybean. PTI immune response and phytophthora resistance of plants can be negatively regulated by the GmLMM1 gene; and by reducing the expression of the GmLMM1 gene, PTI immune response of plant can be effectively enhanced, and phytophthora resistance of plants canbe increased. The clone and functional discovery of the GmLMM1 gene provide important gene foundations and theoretical support for the related mechanisms research of phytophthora resistance, providevaluable gene resources for advancing the research and application of plant defense systems and for breeding new soybean varieties with high disease resistance, and has important application value ingenetic engineering breeding of soybean disease resistance.

The present invention relates to compositions and methods for enhancing plant defenses against pathogens. More particularly, the invention relates to enhancing plant immunity against bacterial pathogens, wherein HopM11-300 mediated protection is enhanced, such as increased protection to Pseudomonas syringae pv. tomato DC3000 HopM1 and / or there is an increase in activity of an ATMIN associated plant protection protein, such as ATMIN7. Reagents of the present invention further provide a means of studying cellular trafficking while formulations of the present inventions provide increased pathogen resistance in plants.
