The invention discloses a method for improving growth and drought-resistant ability of wheat by using arbuscular mycorrhizal fungi to bring the reciprocal symbiosis relation between AM fungi and host plants under drought stress into play reasonably and efficiently. According to the method, the AM fungi having a close symbiotic relation with the wheat are selectively used, and the symbiotic relation between the AM fungi and the wheat is built in a condition control mode to promote the wheat growth and improve drought adaptability. The AM fungi comprise one of glomus monosporum and acaulospora laevis, the two kinds of AM fungi are respectively propagated in an expanding mode in an expanding propagation matrix by using red clovers, and then two AM fungi inoculants and the wheat are cultured together in a symbiotic culture medium. The effective path for profitable symbiosis of the AM fungi and the host plants in adversity conditions is provided, the infection and symbiosis relation with the host plants of the AM fungi is improved in a man-made mode, and the yield of dry crops is improved.

The present invention relates to coal additive and method for raising coke output and performance. The coal additive contains surface activating catalyst, co-solvent, permeation assistant and solvent. When the coal additive is used, the surface activating catalyst is dissolved in the solvent, added into coal through a specific mode, and distributed on the surface of coal and inside coal under the action of the permeation assistant. During producing coke, the coal additive is heated and the volatile component is separated out, to raise the output and performance of the produced coke. The high performance coke may be used in coal burning, dry distilling, gasifying, liquefying and other fields. The present invention can reach the aims of raising the utilization rate of coal, saving coal resource, reducing pollutant, etc.

The invention provides a method for effectively preventing fruit trees iron deficiency yellowtop, which comprises steps: high concentration leaf fertilizers are sprayed in a spring sleep late, and the high concentration leaf fertilizers are sprayed in a mature period of blades for the first time.

The invention relates to a corrosion-resistant and beneficiating non-point source pollution control method for a spring corn slope cropland. The method comprises the following steps of isometry mulch laminating and transplanting of narrow rows, soil anti-corrosion conditioner applying of wide rows and one-time reasonable fertilization. Advantages of single technologies such as isometry mulch laminating of a slope, applying of a soil anti-corrosion conditioner and slow release fertilizer applying are integrated to overcome disadvantages, so loss of water, soil and nutrient is reduced and soil quality is improved. Isometry mulch laminating of a cross slope is combined with a high molecular chemical-physical conditioner and the synergism slow release fertilizer, and labor and capital investments are reduced. Compared with the traditional method in which only pure ridge culture of cross slopes, straw mulching and excessive fertilizer applying are adopted, the corrosion-resistant and beneficiating non-point source pollution control method for the spring corn slope cropland has the advantages of improving the water content by 5-9%, reducing soil bulk weight by 0.05-0.1g/cm<3> and reducing surface runoff by about 15%.
