Main points of cultivation: choose medium fertility field to plant. Apply sufficient base fertilizer, early topdressing, increase the application of phosphorus and potassium fertilizer, the level of fertilization is medium, to prevent lodging caused by partial nitrogen. Medium-term fertilizer should be applied as appropriate, compound fertilizer 5kg / mu or urea 2kg / mu should be applied. Drainage and irrigation should take shallow irrigation in the early stage, long dew and light sun in the middle, which is conducive to taking root and healthy plants, and keeping the field moist in the later stage, which should not be cut off too early.
