Root Causes and Control of Fruit Trees

In the production of fruit trees, the control of root diseases of fruit trees is often neglected. After the onset of the roots of the fruit trees, the plants that were lighter were deciduous, fruit-dropped, and poorly growing; in the worst cases, the entire plant died and suffered heavy losses. The main factors that cause diseases in the roots of fruit trees are: due to poor soil environment, such as soil water, high groundwater level. Roots are infested with pests, such as certain pathogenic fungi and bacteria. Among the two reasons, alfalfa is the main cause of root diseases. Root diseases should be mainly prevention and prevention should be emphasized. In order to avoid and reduce the root disease of fruit trees, the following prevention and control measures should be taken: 1. Do a good job of irrigation and drainage facilities. Early repair of irrigation and drainage ditch, timely removal of orchard water after a rainy day, improvement of drainage facilities, and water retention in the orchard are fundamental measures to prevent root disease and damage in fruit trees. Second, strengthen the cultivation and management. Orchards are given more organic fertilizer to improve soil structure. Foliar spray fertilizer, increase tree vigor, improve the tree's ability to withstand smolt and disease resistance. Third, pay attention to disease tree treatment. When the leaves on the trees lose their water and dry, the leaf edges of the leaves are dry and the leaves turn yellow, the following work should be done: 1. Find the root cause. First break open the rhizosphere soil, dig to the base of the roots, check the root neck, found lesions, follow the lesion down to trace the incidence of the main root, lateral roots and fibrous roots. 2. Remove the root cause. For the whole rot, saw or cut off from the base. The root of the disease must be taken out of the park and buried or burned. 3. Pharmaceutical irrigate root. In order to prevent diseased plants from infecting the rest of the root system, dig 4-6 deep radial trenches 60 cm deep and 30-40 cm wide to the periphery of the tree crown with 300 tons of special WP. Solution, or 70% thiophanate-methyl WP 800 times, or 200 times copper sulphate solution, depending on the size of the tree depending on the amount of drug applied.

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.
