1. Adding organic fertilizer, especially the application of coarse fiber with more fiber, providing comprehensive nutrition for vegetable growth, enhancing the buffering capacity of soil nutrients, preventing salt accumulation and delaying soil salinization.
2. After the vegetables are harvested, the soil is deeply ploughed, and the topsoil rich in salt is turned into the lower layer, and the lower layer of soil with less salt is turned to the upper layer to reduce salt damage.
3. Use the gap to remove the film, and let the surface layer of the soil leaching to the deep layer by sun or rain or flooding.
4. Vigorously promote formula fertilization. According to soil nutrient content, vegetable yield level and fertilizer requirement, rational application of nitrogen, phosphorus, potassium and trace element fertilizer can not only balance soil nutrient balance, but also slow soil salinization and acidification.
5. Deep application of base fertilizer, limited fertilizer. The base fertilizer should be applied to the topsoil by ploughing, so as not to increase the salt content. When the fertilizer is applied, it should try to “eat less mealsâ€.
6. Strongly advocate root dressing. For top dressing, it does not increase soil salinization and acidification, but also provides nutrients for vegetable growth.
An analytical balance is a highly precise laboratory instrument used to measure the mass or weight of samples with high accuracy and precision. It is commonly used in analytical chemistry, pharmaceuticals, and other scientific fields where precise measurements are required. Analytical balances typically have a readability of 0.1 milligrams (0.0001 grams) or less and are designed to minimize external factors that may affect the measurement, such as air currents and temperature fluctuations. They often use a draft shield to protect the sample from external influences and have a built-in calibration system to ensure accurate readings. Analytical balances can be operated manually or electronically, and some models are equipped with advanced features such as automatic calibration, data storage, and connectivity to a computer or other devices.
