Care should be taken to ensure adequate leaf area when falling. At present, many vegetable farmers manage a number of greenhouses, such as falling vines, picking melons and other measures, often hired workers. Due to the high cost of employment, in order to reduce expenditures, some vegetable farmers are too low to reduce the number of vines, resulting in insufficient number of functional leaves, weakened plants, and increased malformation. In general, a cucumber yield is high, requiring functional leaves at least between 13 and 15 slices. This requires that the height of the cucumber should be maintained at 1.5 meters or more. This height can maintain the optimal number of leaves and increase the photosynthetic efficiency, which will strengthen the plant growth and facilitate the farming operation.
Appropriate leaf picking after falling
Falling vines and picking leaves are the experience of many vegetable farmers. However, there are also many vegetable farmers who do not pick up leaves. There are many drawbacks. After the vines fall, the lower leaves are laid on the ground, the leaves are gathered together, and the lighting conditions are extremely poor, which is not conducive to the elevation of the ground temperature; due to the accumulation of the leaves, the air circulation in the lower part of the plant is poor, and the outside temperature in the winter is low. The humidity in the shed increases, the plant's stress resistance decreases, and the pathogenic bacteria are easily infected from the old leaves, which leads to a large disease.
When picking cucumbers in the winter, you must match the leaves. The lower part of the old leaves can be removed first, and then the vines can be sown after the wounds are dried. It is also possible to pick the leaves and the vines at the same time, while picking the leaves and vines. Cucumber falling vines should also pay attention to choose sunny morning, to ensure that the wounds recover as soon as possible, can not choose cloudy or sunny afternoon, reduce the probability of disease infection. After picking the leaves and falling vines, it is necessary to pay attention to spraying the medicines in time. You can choose biological agents such as Trichoderma harzianum or chemical agents such as chlorothalonil and thiabendazole to prevent the plants in advance and improve the disease resistance of the plants.
After the vines are stalked
With the constant vines, the cucumber stems are close to the ground and the humidity is relatively large. The vegetable grower should check the log vines, especially after watering, if it is found to have an adventitious root, cut it off immediately. After rooting, it can be applied to the wound with fine dry soil or copper preparation to prevent the bacteria from infecting the wound. In winter, the cucumber shed is usually covered with mulch. When there is water on the local membrane, the cucumber is also prone to adventitious roots. Therefore, it is necessary to keep the surface of the mulch dry, especially after watering, the water remaining on the mulch and the shed should be timely The water dripping onto the mulch on the membrane leads to the underside of the mulch, or pokes holes in the mulch to allow the water to flow away.

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.
