Summer greenhouse covered straw cooling and moisturizing

In summer, the temperature in the shed is high. In general, the use of ventilation, sunshade nets, and watering are used for cooling. However, sometimes the temperature of the shed is not lowered, and the moisture evaporates at high temperatures. The soil is often in a state of drought and has to be kept for three days. Watering both ends. By covering the crop stalks in the vegetable operation line, not only the ground temperature will not rise rapidly due to the increase of temperature, but also the soil moisture content can be maintained. Practice has proved that this method can usually reduce the ground temperature 4~5 °C, and can extend the water every 5 to 7 days in the summer to extend the water once every 10 to 12 days. Crop stalks are best covered after comminution, so that the vegetables can be directly turned into soil as a base fertilizer to increase soil organic matter.
