(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)
Double Acting Hydraulic Cylinder
A double-acting hydraulic cylinder is a type of hydraulic cylinder that has two ports for fluid entry and exit. It is capable of performing work in both directions, providing both extension and retraction forces.
The operation of a double-acting hydraulic cylinder involves the use of hydraulic fluid, typically oil, which is pressurized to move a piston inside the cylinder. When fluid is supplied to one port, it pushes the piston in one direction, extending the cylinder. When fluid is supplied to the other port, it pushes the piston in the opposite direction, retracting the cylinder.
This type of hydraulic cylinder is commonly used in various applications, such as construction equipment, agricultural machinery, and industrial machinery. It provides the ability to exert force in both directions, allowing for more versatile and efficient operation.
