The high-yield planting method comprises the following steps: 1) selecting and processing cultivating land, selecting the sandy land for tilling, and applying sufficient decomposedmanure, digging holes according to the row spacing of (2-3) * (3-4)m, applying2-5 kg of superphosphate and 2-3 kg of plant ash for per hole; 2) transplanting and planting; transplanting and plating between late August and early September, or between February and March, and applying nutrient solution at the same time; 3) applying fertilizer; applying compound fertilizer in the germination period by 0.5-1.2kg / tree; applying calcium orthophosphate in the florescence period by 0.3-0.6kg / tree, and applying boric acid with a mass concentration of 0.3-0.5% and disease-resistance nutritional agents with the mass concentration of 0.3-0.5% by means of foliar spraying; applying foliar fertilizer with a concentration of 0.3-0.5% during the fruit expansion stage; applying fruit expanding fertilization during full bearing period by 0.5-1.5kg / tree; 4) insect killing; preparing the insect-resist agents from probiotics, indole acetic acid, Chinese medicine extract and carbendazim. The high-yield planting method for improving the disease resistance of citrus has the advantages that the yield and quality of citrus is significantly improved; the disease-resistance of citrus is improved and the fragrance and the sweetness of the fruits are greatly improved.

The invention discloses a Bayer process red mud and gangue porous sintered brick and a production method thereof. The porous sintered brick is prepared from the following raw materials: 60 to 75 parts of Bayer process red mud; 25 to 35 parts of gangue; 2 to 6 parts of tailings or wastes in chemical plants; and 0.5 to 3 parts of pore-forming agent. The preparation method of the brick comprises the following steps: after dehydrating the Bayer process red mud, mixing and uniformly stirring the Bayer process red mud and other ground raw materials, aging for 1 to 3 days, and adding water to stir aged powder in a stirring machine so as to obtain mud; carrying out extrusion forming on the mud under the extrusion pressure of 1.5 to 2.5MPa by adopting a stiff-plastic process so as to obtain a semi-finished product which accords with the specified dimension and the specified shape; and drying a mold brick and sintering the mold brick in a tunnel kiln to obtain the Bayer process red mud and gangue porous sintered brick. The product reaches the national strength standard of the sintered bricks. In the technology, the total use amount of industrial wastes is close to 100 percent; a large number of farmlands are saved; land resources are effectively protected; and the Bayer process red mud and gangue porous sintered brick and the production method thereof accord with the national policies of saving energy and reducing emission and have obvious environmental benefits, social benefits and economic benefits.
