(a) Summary of sodium nitrate:     Compound sodium nitrate Chemical name: 5-Nitro---phenol sodium, O-nitrophenol sodium, p-nitrophenol Sodium     Relative molecular Weight: 191.11 174.16 109.16 English name: Compound sodium nitrophenolate Cas:67233-85-6      (ii) The chemical composition of sodium nitrate:      1, 5-nitro-Invasive sodium sodium (5-nitroguaiacolate)      2, O-nitrophenol sodium (sodium ortho-nitrophenolate) 3, P-nitrophenol sodium (sodium para-nitrophenolate)      (iii) The physicochemical properties of sodium nitrate: 1, 5-nitro More invasive wood phenol sodium: appearance is tasteless orange flake crystal, melting point 105-106 ℃ (free acid), soluble in water, soluble in methanol, ethanol, acetone and other organic solvents.      Stable storage under conventional conditions. 2, O-nitrophenol Sodium: the appearance of red needle-like crystals, with a special aromatic hydrocarbon odor, melting point of 44.9 ℃ (free acid), soluble in water, soluble in methanol, ethanol, acetone and other organic solvents.     Stable storage under conventional conditions. 3, P-nitrophenol Sodium: the appearance of tasteless yellow crystal, tasteless, melting point of 113-114 ℃, soluble in water, soluble in methanol, ethanol, acetone and other organic solvents.　Storage is stable under conventional conditions. After a certain proportion of the preparation of sodium nitrate, the appearance of mixed crystals of red and yellow, easy to dissolve in water, soluble in ethanol, methanol, acetone and other organic solvents. Storage stability under normal temperature conditions.     (iv) The detection methods and uses of sodium nitrate:     High performance liquid chromatography, C18 column, methanol + water as the mobile phase. The broad-spectrum plant growth regulator has the advantages of promoting cell protoplasm flow, enhancing cell vigor, accelerating plant growth and development, promoting root and seedling, protecting flower and fruit, increasing yield and enhancing anti-inversion ability. Can be used alone, but also with fertilizers, pesticides and other complex use.     (v) The five advantages of sodium nitrate:     1, encourage the plant to absorb a variety of nutrients at the same time, remove the antagonistic effect between fertilizers.     2, to enhance the vitality of plants, to promote the plant needs of fertilizer, to resist plant decay.     3, to dissolve the effect of ph barrier, change the ph, so that the plant under the appropriate acid-base conditions to change fertilizers for organic fertilizers, to overcome the dislike of inorganic fertilizer, so that plants love absorption.     4, to increase the infiltration of fertilizers, adhesion, exhibition efforts, to break the limits of plant itself, to enhance the ability of fertilizer into the plant body. 5, increase the utilization rate of fertilizer, stimulate the plant no longer put fertilizer.     (vi) The six main effects of sodium nitrate:     Broad spectrum of sodium nitrate: sodium nitrate is suitable for all crops, suitable for all fertilizers (foliar fertilizer, compound fertilizer, Chong fertilization basal, fertilizer, etc.), suitable for any time.     Sodium nitrate is convenient: the fertilizer one added, no complex production process, regardless of foliar fertilizer, Chong fertilization, solid fertilizer, liquid fertilizer, fungicides, etc., as long as the addition of uniform, the effect is just as magical. The dosage of sodium nitrate is less: according to Mu (1) foliar spraying 0.2 grams, (2) 8.0 grams, (3) compound fertilizer (basal fertilizer, fertilization) 6.0 grams.
