Soak the seeds in warm water for 4 hours at a temperature of about 40°C. The soil should be loose and breathable. Seedling trays (for flower production) or flower pots can be used. Water thoroughly before sowing, and then sow seeds. Cover the culture soil for about 1 cm. Finally, cover with plastic film to maintain humidity. Do not water after re-soil to avoid compaction of the topsoil, and the lower soil will moisten the topsoil. After sprouting and emergence, ventilate and start small ventilation. When the cotyledons unfold the true leaves and peel off the covering film, spray water on the leaves. After the seedlings grow up, the amount of watering can be increased.

2. Specifications indicators
Printing and dyeing industry: mainly used for dyeing vat dyes suspension, leuco acid staining, dispersion and soluble vat dyes dyeing. Also be used for silk / wool interwoven fabric dyeing, the yarn is no color. Mainly used for industrial dye dispersion and diffusion of color lakes manufacturing additives.
Building materials industry: as early strength cement water reducing agent, the amount of 0.5-1% by cement after the shock has good dispersion effect, increasing the strength of cement. Diffused N of concrete tensile strength, impermeability, frost and compressive modulus of elasticity are improved, no corrosion of steel effect.
Pesticide industry: It can be widely used in wettable pesticides, with good dispersion and solubilization, can significantly improve the efficacy, dosage according to product requirements. Example: buprofezin, the amount of 3-5 %; thiophanate amount of 0.8-1.5 %, 0.8-1 % Kai Ling vegetables.
Electroplating industry: the color is added, crossing pigment dispersants N allows uniform dispersion can significantly improve the plating surface brightness, and the amount is usually 10% of the pigment.
Rubber industry: rubber (latex) of industrial production process, the dispersed substances such as sulfur accelerator, antioxidant zinc oxide fillers ( such as barium sulfate , calcium carbonate ), etc., added to the dry weight of a dispersing agent N2-4% , 10% dispersant solution prepared in advance , and along with the other components in a ball mill grinding , can improve the dispersion effect and shorten the milling time .
Packing: 25kg bags.
Storage: two years and must be upload and download lightly.
