The invention relates to a high-performance TC11 tube and a preparation thereof. According to the preparation method, the finished product TC11 tube is prepared by firstly preparing a TC11 titanium alloy cast ingot from a first-class titanium sponge, an aluminum-vanadium alloy, an aluminum-zirconium alloy and scrap zirconium by virtue of strict control of materials and the melting process, forging the cast ingot to obtain a black-rust sheared billet, then machining and carrying out surface grinding to obtain a extruded ingot billet, drilling the ingot billet, sheathing, heating and extruding to obtain a tube billet, then carrying out hot straightening, surface treatment and heat treatment and finally machining, such as boring and turning to obtain the finished product TC11 tube. The TC11 titanium alloy tube prepared by the preparation method disclosed by the invention has the characteristics that (1) the TC11 titanium alloy tube has very high strength, ductility and impact properties; (2) the tube having relatively high tolerance level can be obtained; (3) the microstructure of the TC11 titanium alloy tube is uniform and stable; and (4) the TC11 titanium alloy tube has excellent corrosion performance. The TC11 titanium alloy tube can meet the high-standard application requirement in the petroleum industry.

The invention discloses a solar energy self-generating tent. The solar energy self-generating tent comprises two U-shaped bottom frames, both ends of the side wall of each U-shaped bottom frame are rotatingly connected with a first retractable rod and a second retractable rod respectively which are movably hinged; the tops of the two U-shaped bottom frames are fixedly connected with a mounting frame which is rotatingly connected with a first support frame and a second support frame; the side walls of the U-shaped bottom frames are fixedly connected with a plurality of positioning rings and winding mechanisms, steel wires are wound inside the winding mechanisms, and one end of every steel wire is fixedly connected with a hook; the outside of a framework is covered by a tent cloth. The solarenergy self-generating tent is convenient to assemble and build and can be retracted and folded for convenient storage and carrying; meanwhile, the solar energy self-generating tent has an adjustingfunction and meets inside power supply demands through solar energy, thereby being easy to popularize and apply.

The invention discloses a high-efficiency method for in vitro regeneration of quinoa cotyledon nodes. Using quinoa cotyledon nodes as the starting material, a large number of adventitious buds and regenerated plants can be obtained after induction, which provides technical support for quinoa transgenic. The method for in vitro regeneration of quinoa cotyledon nodes established by the invention provides technical support for the creation of new quinoa varieties, molecular mechanism research and the like, and promotes the development of the quinoa industry.

The invention belongs to the technical field of agricultural production and particularly relates to a method for summer corn salt-controlled yield increase in light and moderate saline-alkali soil of the Yellow River Delta. According to the method, a summer corn fertilizer application amount and operation method, an irrigation amount and a salt-controlled yield increase water and fertilizer operation method for a corresponding irrigation principle and method are formulated according to on-site soil saline-alkali, soil fertility and climate and summer corn growth conditions in light and moderate saline-alkali soil of the Yellow River Delta. The method comprises the following steps: (1) land preparation seeding and seedling stage and jointing stage water and fertilizer operations; (2) jointing and tasseling stage water and fertilizer operations; and (3) tasseling and filling stage water and fertilizer operations. According to the method, by reasonable operations of water and fertilizer, salt adjustment and salt control, soil improvement and fertilizer supply, seedling protection and strong seedling cultivation, growth promotion and yield increase can be performed on summer corns planted in the light and moderate saline-alkali soil of the Yellow River Delta. The method has the advantages of being simple and practical, reducing cost, increasing benefit and being high in applicability and easy to popularize. The method has remarkable economic, ecological and social benefit if popularized and applied in large area in summer corn planting areas of the light and moderate saline-alkali soil of the Yellow River Delta area.

The invention relates to a maize lodging-resisting stress-resisting yield-increasing regulator, and a preparation method and application thereof. The regulator contains the following components: iminodisuccinic acid 140-280 g / L, ethephon 90-180 g / L, zinc sulfate heptahydrate 50-100 g / L, active agent also used as a spreading agent 5-10 g / L, and the balance of water. The active agent also used as the spreading agent is selected from one or more of Tween 20 and Tween 60. The regulator of the invention can significantly enhance the ability of maize such as resisting low-temperature chilling injury, high temperature, drought and mild saline-alkali stress, increase the lodging resistance of maize, increase the number of ears per mu, grain number per ear and thousand-grain weight, and increase the maize yield by 20% or more. At the same time, the regulator has the characteristics of low cost, convenient use, and less residues in the field. The regulator is easy to popularize and apply, and has a positive role in promoting China corn production.
