Pay attention to the dosage: all kinds of chemical fertilizers should master the optimal dosage. If the application is too late, it will easily lead to late maturity or fat damage. If the dosage is too small, the effect and ideal yield will not be achieved. In general, the amount of urea is preferably 10-15 kg per mu, 15-20 kg of ammonium nitrate, 20 kg of phosphorus nitrate, and 20-25 kg of ammonium bicarbonate.
Pay attention to the fertilization method: ammonium bicarbonate is highly volatile, and should not be applied to the surface and applied with water. The depth of the hole is 7~10 cm, and the cover is tight after application. Urea, ammonium nitrate, and phosphorus nitrate can be applied to the trench or used.
Pay attention to the watering time: the ammonium bicarbonate and the nitrophosphate fertilizer can be watered immediately after application. Urea is easily lost with water in the soil. It should not be watered immediately after application. It should be watered at intervals of 5-7 days.

Single Use Trocar Site Closure Device
A fascial closure device is a laparoscopic instrument used to close the fascia, the layer of tissue that covers and separates abdominal organs and muscles. The device is used during laparoscopic surgery to create a secure closure of the fascia after the surgical procedure is complete.
The fascial closure device consists of a needle and suture material attached to a handle. A needle is used to puncture the fascia, then suture material is passed through the puncture site and tied tightly to close the fascia. The device's handle is used to control the movement of the needle and suture material, allowing precise placement and closure of the fascia.
The use of fascial closure devices during laparoscopic surgery can help reduce the risk of postoperative complications such as hernias, wound infections, and intestinal obstruction. It also closes the fascia more quickly and efficiently, reducing the overall time required for the procedure.
