Foliar fertilization at flowering stage of rapeseed

(agricultural Wealth net) the key to fertilization in rape flower horn stage is skillful. The growth potential of most rape is weak in the early stage, and it is easy to appear premature senescence in the later stage. Such as less fertilizer in the early and middle stage, insufficient spring flowers, small individual population, or excessive fertilization in the early stage, fertilizer control in the middle stage, and premature senility in the later stage. Therefore, foliar fertilizer of available nitrogen fertilizer should be applied at the early or final flowering stage. For example, if there is enough fertilizer in the early and middle stage, the plant growth is normal, it is appropriate to spray available phosphorus and potassium foliar fertilizer. 0.3% urea solution or 0.3% potassium dihydrogen phosphate solution is generally used.
