Spring wheat sowing fertilizer pay attention
Spring wheat sowing and fertilization Note: Spring wheat sowing in Tianjin can generally be completed before the end of March. Fertilizer should be applied to the base fertilizer. Since spring wheat is more sensitive to phosphorus than winter wheat, and spring wheat grows faster and faster, it begins to differentiate in the three-leaf stage, develops reproductive growth and grows in vegetative growth, and needs to absorb large amounts of fertilizer. Therefore, at the time of sowing, the bottom fertilizer must be given enough. Special attention should be paid to increasing the application of phosphate fertilizer and potash fertilizer. In the fertilization method to master shallow fertilizer, the depth of 7-10 cm is appropriate. A double box planter can be used to sow the seeds before sowing. Or stand-alone replay, sowing after sowing. The second is to use fertilizer and water. Pay attention to water topdressing, combined with watering 35-45 kg of ammonium carbonate per 667 m2. If there is no watering condition in spring, you can apply 20-30 kg of urea at one time.
