Seeding first wash the seeds with 0.5% saline, then soak seeds with water for 1 to 2 hours, and let the water dry for 2 to 3 hours. Mix the red, yellow mud and fine soil with white turtle pesticides. The seeding amount per mu of nursery field is 1000-2000 grams. The amount of live land per acre is 250-300 grams.
The weeds in the harvested rice fields were removed with herbicides 2 to 5 days before sowing. Linyi Fertilizer Network Copyright
The base fertilizer is applied to 25 to 30 kg of compound fertilizer containing 15% of nitrogen, phosphorus and potassium. Linyi Fertilizer Network Copyright
Two days after sowing the rapeseed, the main ditch, the trough, the lumbar ditch and the furrow are opened according to the width of 1.5 to 2 m. The ditch and the ditch are connected, and no water in the field after the rain reaches the convenient irrigation and drainage. Break the ditch clods evenly and spread the kneading surface, level the kneading surface, and then lay a layer of straw to protect the drought. Linyi Fertilizer Network Copyright
Seedling management rapeseed emergence 2 to 4 leaf stage each applied water and fertilizer once, each time with urea 50 ~ 80 grams plus boron, zinc, iron, magnesium fertilizer micro-fertilizer 50 kg spray. The seedlings are 3 to 5 leaf stage, and the surface of the seedlings is sprinkled with water and soil. After sowing, the manure water is irrigated every 3 to 5 days in the dry weather. Once the seedlings are strong, the seedlings are uniform, and the seedlings are 9000 or so per mu. The main inflorescence is increased to increase the number of pods per unit area. After the rapeseed emerged 4 leaves, the weeds were clustered, and the herbicide was sprayed once after 3 pm on sunny days for weeding. Linyi Fertilizer Network Copyright
Manage the ditch drainage after the spring to prevent cold damage and enhance soil permeability. Such as rapeseed field weeds, spray herbicides. At the same time, the lower leaves, yellow leaves and diseased leaves of rapeseed were removed to reduce the source of sclerotinia. The first flowering stage and the full flowering stage of rapeseed are sprayed once, and “Shu Kewei†plus “Shu Keling†are used to treat both diseases and insects. The use of borax to control rapeseed is not true. Linyi Fertilizer Network Copyright

Sodium lignosulfonic Acid Sodium Salt is sodium ligninsulfonate is a natural polymer, anionic surfactants. Has a strong dispersibility, suitable for the solid dispersion in the water medium. Due to the different molecular weight and functional groups have different degrees of dispersion, can be adsorbed on the surface of a variety of solid particles, can be metal ion exchange, but also because of its organizational structure of the existence of a variety of active groups, which can produce condensation or And hydrogen compounds with other compounds. In industry, Sodium Lignosulfonate is widely used as a dispersant and wetting agent. Dyeing industry used in the dispersant -NNO is sodium lignosulfonate as the main Raw Material compound.
