The core of the technology is the shifting of the fertilization weight and the shift of the spring dressing time.
(1) Wheat nitrogen fertilizer post-shifting technology is suitable for the field management of high-yield wheat fields with strong fertilizer and water conditions and strong and medium-gluten wheat.
(2) Determine the reasonable ratio of base fertilizer to top dressing, and shift the proportion of fertilization. The nitrogen fertilizer post-shifting technology reduced the proportion of base fertilizer of nitrogen fertilizer to 50%, and the proportion of topdressing fertilizer increased to 50%; the proportion of fertilizer with high soil fertility was 30%-50%, and the proportion of topdressing was 50%-70%.
(3) In the spring, the time of topdressing was shifted, and the reasonable population structure and yield structure of two types of tiller-to-ear type were established. Under normal circumstances, spring topdressing is moved from the greening period or the rising period to the jointing stage; the soil with high soil fertility uses the varieties with high tillering rate, and the spring topdressing can be carried out during the jointing stage to the flag leaf.
(4) Pay attention to timely control of wheat stripe rust, powdery mildew, scab, sheath blight, aphids; use artificial or chemical methods to control weeds. (Dongping County Agricultural Bureau Zhang Qingjie)
