Watering at the right time. Due to the short growth period of spring wheat, an "early" word is advocated on the field management. Therefore, irrigation is better for early irrigation, and irrigation is carried out in the case of fertile land and heavy rain. Generally, the head water is poured in the second leaf and one heart. The second water is generally filled 7-10 days after the head water, and it is required to be filled and permeated.
Reasonable topdressing. Under normal circumstances, in the spring wheat two leaves from one heart to three leaves, urea can be chased 5 kg, and second water is used to recover urea 8-10 kg. At the jointing and booting stage, the normal growing wheat field combined with irrigation water is applied 10-12 kg per mu. Wang Changtian should use less than 5-10 kg of urea. Appropriate application of weak seedlings, 10-15 kg of urea. It not only provides sufficient nutrition for the robust growth of spring wheat, but also prevents excessive growth.
Prevent weeds in the field. Chemical weeding of wheat should be carried out early after the emergence of wheat, and it should be sprayed before the emergence of cotton to ensure the safety of medication. Should choose a small drifting herbicide, such as broadleaf net.
Pest control. For bacterial stripe disease, foliar spray is applied with agricultural streptomycin in the early stage of the disease, and foliar spray is applied to the rust pathogenesis center. Spring wheat pests, aphids, wheat-skinned horses, etc., are controlled by insecticides combined with foliar fertilization when wheat is flagged.
Foliar spray fertilizer. In combination with disease prevention, foliar zinc sulfate fertilizer can be sprayed on the foliar surface, and potassium dihydrogen phosphate and dry land dragon can be sprayed in the middle and late stages to prevent dry hot air damage.
Hand Pads And Roll
Non-woven abrasive scouring pad roll is made from high quality nylon fibre.
Bonding abrasive on the non-woven with special resin. It's with high flexibility.
Industrial scouring pads are mainly used in the coating treatment of the surface of metal, wood and other materials, mechanical maintenance and cleaning such as cleaning, polishing, rust removal, deburring, and high-quality appearance decoration line processing operations.
The characteristics of industrial scouring pads are generally mainly elastic grinding, which can effectively prevent excessive cutting and scratching the surface of the work piece; followed by cold cutting, the common structure is effective for heat dissipation, which can prevent discoloration and deformation caused by overheating of the work piece during processing; its The third is that industrial scouring pads can prevent clogging, water and oil resistance; during the grinding process, the fibers will continue to be lost, and new grinding ore will continue to form naturally, providing better processing quality for the work piece.
