Once the amount of fertilizer should not be too large. If there is a large amount of one-time fertilizer in drought, it is easy to be washed away when it encounters heavy rain after drought. This will not only cause economic losses to farmers, but also pollute the environment.
Fertilizer deep application, with hydraulic fertilizer Under drought conditions, if the fertilizer is applied only on the surface, the fertilizer is volatile. If the drought is followed by heavy rain, it is also easy to be washed away by rain. Therefore, chemical fertilizers should be applied as deep as possible.
Pay attention to the reasonable mix of fertilizers, especially potassium fertilizer and boron fertilizer. Many research data show that suitable potassium can increase root-shoot ratio and enhance crop water absorption capacity; and under drought conditions, suitable potassium can also promote the accumulation of proline, Regulate cytoplasmic turgor pressure to enhance crop drought resistance.
In addition, drought is prone to induce boron deficiency in crops, especially growing fruit trees. Therefore, in drought conditions, it should pay attention to the appropriate application of potassium fertilizer and boron fertilizer.
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
