The application discloses a compound fertilizer for promoting cotton high yield and a preparation method thereof, relates to the technical field of cotton fertilizer, and comprises first mother liquor A, second mother liquor B and third mother liquor C which are prepared, stored and packaged separately; the first mother liquor A contains urea phosphate, monoammonium phosphate, anhydrous citric acid, malic acid and manganese sulfate monohydrate; the second mother liquor B contains commercial 11-37-0 liquid ammonium polyphosphate, ammonium salt type polyaspartic acid solution, purified fulvic acid clear liquid and tri-potassium citrate; and the third mother liquor C is a mixed system of polyol complex state boron clear pre-liquid and medium complex state zinc pre-liquid. The application can improve the effective state stability of phosphorus, zinc and boron, reduce the risks of precipitation fouling and dripping head blockage, alleviate the risks of local salt peak and root injury in the seedling stage, promote the uniform emergence and young root growth of cotton, and improve the yield.

The utility model belongs to cable field especially, it is a kind of graphene composite copper conductor anti-interference flame-retardant low-voltage power cable, to the lack of effective temperature monitoring means of current cable, cannot grasp the temperature change in the process of cable operation in real time, anti-interference ability is limited, the weight of traditional cable is larger, the problem of installation and handling difficulty, present and propose following scheme, including graphene composite copper conductor, its inside interval inserts graphene oxide fibre sensor;Crosslinking polyethylene insulating layer covered in the graphene composite copper conductor outside;Polyimide aluminium foil composite tape shielding layer covered in the outside of multiple conductors, in the utility model, thermal response hydrogel microcapsule breaks when contacting high-temperature fire source, releases ammonium polyphosphate flame retardant, and zinc oxide reacts to generate expansion carbon layer, effectively prevents fire spread, realizes flame-retardant self-repair function, graphene oxide fibre sensor interval inserts graphene composite copper conductor inside, can monitor cable temperature change in real time.

This invention discloses a production process for cationic trilobal profiled recycled polyester fiber, belonging to the field of spinning technology, including the following steps: (1) feeding recycled cationic polyester chips into a crystallization drying system for crystallization drying treatment; (2) melting the dried recycled cationic polyester chips and a modifier, or melting the dried recycled cationic polyester chips to obtain a spinning melt, then conveying the melt to a spinning box, metering it with a metering pump, and then pressing it into a spinning assembly to extrude and form a nascent filament bundle; (3) subjecting the nascent filament bundle to post-heating, airless zone, ring blowing cooling, bundling and oiling treatment, and then to pre-networking, stretching and shaping, and winding to obtain cationic trilobal profiled recycled polyester fiber. The cationic trilobal profiled recycled polyester fiber of this invention can increase the dyeing rate and quick-drying performance of polyester fiber, and the introduction of a core-shell structure with ammonium polyphosphate as the core and chitosan as the shell can increase the flame retardant performance of the fiber.
