Potassium has significant effects on the growth and development, dry matter accumulation, yield and quality of rapeseed. In the absence of potassium, the plants tend to wilt, the seedlings are wormy, the parts between the veins are convex upwards, and the leaves are bowed; the leaves are darker, usually dark blue-green, chlorotic between the leaf margins or veins, initially often in the form of a needle Spots, the final plaque necrosis, the leaves completely dead when potassium deficiency is severe, but do not fall off. Rape begins to die in plants that are extremely low in potassium until flowering. Remedial measures: Early lack of potassium, per acre with 7 ~ 10 kg of potassium chloride or 75 ~ 100 kilograms of wood ash ditch topdressing; later with 0.1 ~ 0.2% potassium dihydrogen phosphate solution foliar spray. Speed Bumps & Cable Protectors When the car passes, Speed Bumps can be remind the driver to slow down the speed. To avoid accidents.
