The invention provides a insulated wire and cable. The invention aims to provide insulated wire and cable with low temperature properties, flexibility, oil resistance, cold resistance, fire retardancy and mechanical properties. The insulated wire has a conductor and insulated layer formed peripherally around the conductor. The insulated layer is made of a non-halogen flame-retardant resin composition. Metal hydroxide is added in a base polymer containing an ethylene-vinyl acetate copolymer; the metal hydroxide includes magnesium hydroxide; the base polymer has a vinyl acetate content of 20 mass% or higher to below 50 mass%. The insulated layer has advantages of fire retardancy, mechanical properties,low temperature properties and cold resistance.

The invention discloses an ecological BB fertilizer, relating to a mutifunctional ecological environment friendly compound fertilizer, which is formed by mixing functional urea, controllable slow release sulfurcoated urea, monoammonium phosphate, diammonium phosphate, potassium sulfate particle (or potassium chloride), agricultural magnesium sulfate particle, ammonium sulfate, bio-organic inorganic compound fertilizer, endophytic PASP fertilizer synergist DA-6, plant growth regulator and trace elements. Special ecological BB fertilizer for different plants can be prepared by soil testing formula, according to different farm crops and different soil structure. The ecological BB fertilizer can take effect for 3-120 days, the nutrition release is balanced, biological stress of the farm crop such as drought resistance, cold resistance, salt resistance, or the like can be improved. The product of the invention has great operation significance for increasing yield of grain, reducing production cost, steadily increasing grain production, keeping rural incomes growing, improving utilization rate of the fertilizer, reducing fertilizer waste, protecting ecological environment, guaranteeing farm crop quality and safety, and ensuring sustainable development of the agriculture.

The invention provides a cold-resistant anti-twisting anti-bending flame-retardant foamed coating adhesive for a textile and a treating method. The cold-resistant anti-twisting anti-bending flame-retardant foamed coating adhesive is prepared by uniformly mixing, by weight, 80 to 100 of a flexible and elastic foamed coating adhesive, 2 to 4 of an enclosed type isocyanate cross-linking agent and 1 to 3 of a high-permeability softening agent under stirring, then adding 20 to 25 of crystal II type ammonium polyphosphate, 10 to 15 of expandable graphite and 4 to 6 of micro polytetrafluoroethylene powder, and adequately introducing air until a foaming state is reached so as to allow the size of the obtained mixture to increase by 1 to 3 times so as to obtain the coating adhesive. A fabric is subjected to calendering pretreatment and then coated with the prepared coating adhesive. The coating adhesive is simple and convenient to produce, effectively overcomes the problem of hygroscopicity of ammonium polyphosphate and the problem of meltability of a flame-retardant textile, and has good flame retardation, cold resistance, twisting resistance, bending resistance and air permeability; and the treated fabric has good elasticity and is comfortable to wear.

The present invention proposes a cold resistance functional gene CsLac18 isolated and cloned from sweet orange, its nucleotide sequence is shown in SEQ ID NO.1, and its corresponding amino acid sequence is shown in SEQ ID NO.2. The gene CsLac18 of the present invention was introduced into tobacco and Citrus aurantii for functional verification, and it was found that the obtained transgene overexpression plants had significantly improved cold resistance, while the transgene silent expression plants had significantly reduced cold resistance. The invention provides important gene resources for plant cold-resistant genetic engineering and can improve the cold-resistant performance of plants.
