In vegetable seedlings or after planting, if the seedlings grow slowly, the roots age and rust, the leaves are small and thick, and the seedlings are brittle and inelastic, indicating that the vegetable seedlings begin to age, then we need to find the reason for the aging of the vegetables. And take appropriate remedial measures. Today, Xiaobian talks about the causes and remedies for the aging of vegetable seedlings. First, why do vegetables appear aging? 1. The main reasons are excessive bed soil, low bed temperature, poor soil permeability, too long seedling age, lack of nutrients in the soil, or low temperature and rain after planting. 2, during the nursery period, afraid of long, if the long-term strict control of water or seedlings are too long, it is easy to cause seedling aging. 3, with seedling nursery seedlings and groundwater partition, watering is not timely, resulting in soil dry and aging seedlings. 4. After the plant is planted, the low temperature and even rainy plants have slow roots and stagnant growth, which causes the seedlings to age. Second, what are the precautions for vegetable seedlings in winter and spring? 1. In the process of planting vegetables, it is necessary to control the temperature of the nursery environment reasonably. The temperature should not suddenly be high and suddenly low, which is very unfavorable for the growth of vegetables. At the same time, vegetables cannot be grown for a long time under low temperature conditions. 2, master the vegetable seedling age, the seedling age should not be too long. 3. Strictly control the seedling method of different vegetables. When carrying out seedlings, the time of low temperature exercise should not be too long. It is best to use the method of temperature control and water control, especially in the seedling stage, to provide sufficient water in the watering Be ventilated in time to prevent the seedlings from growing. 4. In the process of vegetable planting, once the seedling aging phenomenon occurs, in addition to the normal management of temperature and moisture, the planter can also spray water on the foliar surface or 0.2% to 0.3% potassium dihydrogen phosphate, or spray some photosynthesis. Micro fat. At the same time, for the aging seedlings, low concentrations of gibberellin can be sprayed on the leaves to promote the rapid growth of the seedlings. The results are often used to detect disease. Gastric acidity pH is 3.5 ~ 7.0, common in atrophic gastritis, gastric cancer, secondary iron deficiency anemia, gastric dilatation, hyperthyroidism. Reduced gastric acidity is seen in duodenal reflux, gastric ulcer, gastric cancer, atrophic gastritis, chronic gastritis, pernicious anemia, etc. Such as duodenal bulb ulcer, Zhu-Ai syndrome, pyloric obstruction, chronic cholecystitis, duodenal fluid reflux will also increase pH.

PH0.9 ~ 1.8.
Clinical significance of test results
(1) Gastric acid reduction: pH3.5 ~ 7.0, common in atrophic gastritis, gastric cancer, secondary iron deficiency anemia, gastric dilatation, hyperthyroidism. Reduced gastric acidity is seen in duodenal reflux, gastric ulcer, gastric cancer, atrophic gastritis, chronic gastritis, pernicious anemia, etc.
(2) Increased gastric acidity: in duodenal bulb ulcer, Zhuo-Ai syndrome, pyloric obstruction, chronic cholecystitis, duodenal fluid reflux will also increase pH.
