Summer vegetables are in the wrong zone
Misunderstanding 1: Shade net covering all day In recent years, in order to reduce the temperature in the summer shed, to create a suitable environment for the growth of vegetables, vegetable farmers often use covering shading nets or spray mud on the film to avoid strong The harm of light directly to vegetables. However, it is worth noting that covering the sunshade of the sunshade will also have a negative impact. If the covering time is too long, the light in the shed will be weakened and the photosynthesis of vegetables will be affected. However, there are many vegetable farmers who are planning to save time. After covering the shade net in summer, they will not withdraw anymore. This will not only affect the photosynthesis of vegetables, but also cause plant growth and affect the normal growth of vegetables. Therefore, the shade net should be used only when the noon light is strong and must not be covered all day long. In addition, silver-gray shade nets should be used as far as possible.
Misunderstanding 2: Chicken droppings are stored in pits for a few days even if they are decomposed of fresh chicken manure. Covering them with plastic film for 20-30 days can fully decompose them. Many vegetable growers in the cultivation of summer vegetables, because of the time, most of them are just a few days of boring stuff, the result is often due to chicken manure is not fully decomposed, resulting in just planted vegetable roots dead seedlings. Therefore, before using chicken manure, summer farmers must fully decompose chicken manure, and must not be eager to seek success, causing some unnecessary losses.
Misunderstanding 3: The greater the amount of irrigation in the summer, the better the summer temperature is, and the soil moisture and plant water evaporate quickly. The vegetable farmer often increases the amount of irrigation during irrigation, resulting in excessive humidity and poor air permeability, resulting in the roots of the newly planted vegetables. Dead seedlings. In this remind everyone that no matter what the season, irrigation must be a small number of times, should not flood irrigation. The time for irrigation should be selected in the morning, avoid watering after 12 noon, so as not to cause the roots of the vegetables to suddenly encounter cold water and cause rooting at high temperatures. In addition, when the vegetables are planted, they must be ridged and cultivated. The benefits of ridge cultivation in the summer are as follows: First, the soil is likely to dissipate temperature. The second is that it is not easy to cause the roots of vegetables when irrigation, and there are few dead trees and strong growth.
3D dental imaging is slowly becoming the new standard of care in dental practices. 3D dental scanning allows dentists to digitally reconstruct your teeth in 3D. Dental practitioners can interact with this 3D model and visualize aspects of the model that would otherwise be difficult or impossible to access. This new perspective allows clinicians to more effectively diagnose an issue or provide a more effective means of treatment.
3D dental scanner is most commonly utilized for cosmetic and restoration purposes, such as reconstructive therapy or oral surgery. 3D imaging allows for planning and customizing services for procedures such as bone grafts, implants, and root canals. 3D scanning is also often used to create 3D images for orthodontic treatment.
