Fertilization time is the key period of flower bud differentiation of kiwifruit. According to the maturity of each variety, the fertilization time should be controlled after fruit picking and before defoliation. After fruit picking, because the leaves lose the role of regulating water, temporary functional decline often occurs, so the base fertilizer should be applied early.

Before the application of fertilization, the 0.5% urea solution was sprayed once on the leaves, which could increase the photosynthesis of the leaves, promote the return of nutrients to the roots and stems, and increase the nutrient reserve. At this stage, kiwifruit tree fertilization should be applied with NPK fertilizer, mineral fertilizer and organic fertilizer. In the fruit-fruit kiwifruit tree, the total fertilization amount of NPK is 0.5 kg, and it is applied at a ratio of 1:1:1; the mineral fertilizer is applied to each tree 0.25 kg; the total fertilization amount of each tree of bio-organic fertilizer It should be kept at 1.5~2.5 kg.

Fertilization method Root fertilization can be carried out in three ways: whole garden application, hole application and ditch application. After fertilization, it should be irrigated once in a timely manner; foliar spray method is simple and easy to use, with small fertilizer amount and quick effect, but need to pay attention to Yes, it is best to do it on a cloudy, sunny morning or in the evening without wind.

Disposable Laparoscopic Trocar

Disposable laparoscopic trocars are typically made of plastic or metal and are designed for single-use only. They are available in a range of sizes and shapes to accommodate different patient needs and surgical procedures. The trocar is typically inserted into the patient's abdomen using a technique called "blind insertion," which involves inserting the trocar through the skin without direct visualization of the underlying tissue.

The disposable nature of these trocars makes them a convenient and cost-effective option for many surgical procedures. They are also less likely to cause infections or other complications compared to reusable trocars, as they are sterile and do not require cleaning or sterilization between uses. However, it is important to follow proper disposal procedures to prevent contamination and ensure patient safety.


Disposable trocars are designed for single use, reducing the risk of infection and cross-contamination between patients. Trocars are usually made of plastic and come in a variety of sizes, depending on the size of the incision and the surgical instruments used.
