First, the lack of symptoms 1, lack of boron. When the supply of boron is insufficient, the petiole will produce an annulus. The top buds of the cotton plants will often be necrotic. The cotton plants will grow short and have many branches. In severe cases, the cotton plants will show no flowers, no bells, or buds but no flowers. 2, lack of zinc. When the supply of zinc is insufficient, the cotton leaves are small and there is a lack of green between veins, so that the leaf tissue is dead and the green part becomes bronze. 3, lack of manganese. When the supply of manganese is insufficient, the leaves become cup-shaped, chlorosis between veins, and the internodes become shorter and the plants become dwarfed. Second, remedial measures 1, boron fertilizer application. In the absence of boron in soil, the effect of using boron fertilizer to increase production is very obvious. The application method of boron fertilizer is better to use extra-root spray. 0.2% borax or 0.1% boric acid solution can be used to spray water once in the bud, early flowering and blooming stages. 15-25 kilograms per acre period, 35-40 kilograms at the beginning of flowering, 50-60 kilograms at flowering stage, and borax for basal application, 0.5 kilograms of borax per acre. 2, zinc fertilizer application. The concentration of zinc sulphate foliar spray fertilizer is 0.1-0.2%, which is suitable for spraying at bud stage, early flowering stage and full flowering stage. The water volume is 15-25 kg per mu bud, the initial flowering period is 35-40 kg, and the flowering period is 50- 60 kg; basic application of zinc sulfate, 1.5 kg per acre. 3, manganese fertilizer application. The concentration of manganese sulfate foliar spray fertilizer is 0.1%. It is suitable to spray once in bud stage, early flowering stage and flowering stage. The water quantity is 15-25 kg per mu bud stage, the initial flowering period is 35-40 kg, and the flowering period is 50-60 kg. ; Base applied manganese sulfate, manganese sulfate required 1 kg per mu. Disposable Endo Fascia Closure System
Disposable minimally invasive fascial closure device is a medical device used to close the abdominal fascia layer after laparoscopic surgery. The device consists of a needle and suture that can be inserted through a small incision in the skin and used to close the layers of fascia without the need for a larger incision. The device is designed to reduce the risk of complications associated with traditional methods of fascial closure, such as wound infection, hernia and dehiscence. The single-use nature of the device also reduces the risk of cross-contamination and infection. Use of the device could shorten recovery time and improve outcomes for patients undergoing laparoscopic surgery.
