The invention provides a fertilization management method of adult cocktail grapefruit and a planting method of cocktail grapefruit comprising the same, and relates to the technical field of agricultural planting. The fertilization management method adopts a gradient during the entire planting process of adult cocktail grapefruit, specifically during the fruit setting period before flowering, the fruit expansion period, the early fruit ripening period, the middle and late fruit ripening period, the fruit picking period and the pruning period. Nitrogen reduction, gradually increasing potassium fertilization mode for fertilization management, thereby effectively improving the fruit quality of cocktail grapefruit, and realizing the high-quality and efficient production of cocktail grapefruit.

A rolling and deep-processing short-process integrated manufacturing method of a high-strength steel automobile sheet includes following steps: heating raw materials in a heating furnace, performing controlled rolling including crude rolling and finish rolling, laminar cooling the rolled raw material, performing comprehensive blanking, heating the obtained sheet material, moulding and quenching the sheet material, performing a cutting process and a shot blasting process to obtain a finished product. The raw material is heated to more than 1250 DEG C in the heating furnace. A finish rolling temperature is 820 + / - 30 DEG C. The rolled sheet material is cooled to the temperature of 700 + / - 50 DEG C at a temperature decreasing rate of 10 + / - 5 DEG C / s, wherein the temperature is maintained for 2-5 min. The sheet material is heated to 880 + / - 30 DEG C at a temperature increasing rate of 15 + / - 5 DEG C / s in a continuous heating furnace with temperature maintenance for 3-5 min. The stamping and quenching member is subjected to stamping and quenching at the same time, wherein the flow velocity of cooling water in a stamping and quenching die is 50 + / - 10 DEG C / s. The stamped and quenched member is cooled to 180 + / - 50 DEG C / s to obtain a super-high strength steel part in a homogeneous martensitic structure, wherein the strength of extension can reach higher than 1500 MPa. The method can produce the high-strength steel automobile sheet at a high quality and a high efficiency, can reduce cost, can promote comprehensive utilization of secondary energy sources such as low-temperature waste heat and the like, can achieve integrated production from raw materials to the product, and can achieve energy saving, consumption reducing and environment protecting.

The invention discloses a lightweight concrete porous plate section bar, which characterized in that a concrete mixture is used as a working masterbatch. The working masterbatch comprises the following materials by weight: 20-30 parts of cement, 30-60 parts of fly ash, 30-40 parts of quartz sand, 10-15 parts of a lightweight blend, 0.4-0.6 part of cellulose ether, 5-8 parts of plant fiber and 1-3 parts of other additives. The preparation technology is as below: first conducting a first dry stirring on the raw materials for even mixing, then adding 10-18 parts of water for a secondary even mixing; and then conducting plasticity extrusion moulding by a vacuum extruder and a porous extrusion mold. The invention uses regenerated industrial wastes by a large proportion of, reduces the dosage of cement, reduces the cost and is beneficial to saving of resource and energy and environmental protection.
