In summer, the temperature in the shed is high. During the production, the method uses enhanced ventilation, covering the shade net, watering and other methods to cool down. However, sometimes the temperature of the shed can not be lowered, and the water evaporates quickly under high temperature. The soil is often in a dry state and has to be two days. Watering. Covering the crop straw in the vegetable operation line, not only the ground temperature will not rise rapidly due to the rising temperature, but also the soil moisture can be maintained. Practice has proved that this method can usually reduce the ground temperature by 4~5 °C, and can extend the water every 5-7 days in the summer to a water every 10-12 days. The crop straw is best covered after smashing, so that the vegetables can be directly turned into soil as a base fertilizer after the clearing of the garden, and the soil organic matter is increased. In the summer, the temperature in the shed is high. The production is generally heated, covered with shade nets, watered, etc., but sometimes the temperature of the shed can not be lowered, and the water evaporates quickly under high temperature. The soil is often in a dry state and has to be three days. Watering the two ends. Covering the crop straw in the vegetable operation line, not only the ground temperature will not rise rapidly due to the rising temperature, but also the soil moisture can be maintained. Practice has proved that this method can usually reduce the ground temperature by 4~5 °C, and can extend the water every 5-7 days in the summer to a water every 10-12 days. The crop straw is best covered after smashing, so that the vegetables can be directly turned into soil as a base fertilizer after clearing the garden, increasing soil organic matter.

When storing precision seamless pipes, pay attention to moisture, dust, oil, lubricating oil, etc., as well as rust on the surface, or poor corrosion resistance.

When the film is immersed in moisture between the film and the steel substrate, the corrosion rate is faster than when the film is not applied. Store in a clean, dry and ventilated place, keep the original packaging state, the film of stainless steel should avoid direct light, the film should be periodically checked, if the film is degraded (film life of 6 months) should be replaced immediately, padding If the packaging material is soaked in paper, remove the paper immediately to prevent surface corrosion.
