Impact of Heat on Vegetable Crops and Mitigation Strategies

The adverse impact of global warming on agriculture, food protection downturn around the world. A sharp increase in the earth’s temperature range is expected, and whether the soil profile may result in the average temperature of the earth with the help of 2100 increased 1.8–4 °C, thermal strains can exist in the absence of or determine soil moisture is inside a the key risks and/or the plight of the prosperity and development of plants. Some plants in the growth phase are essential in additional costs strain of risks warm. Extreme warm pressure can reduce root development of plant photosynthesis and transpiration efficiency and negatively affect the plant, which can be combined effect of the negative rate of return. Effect of heat and water pressure coupling yield of many crops is much more effective than the effect of (S) individual human stress. Heat stress, in general, described as the degree of increase exceeds a threshold value for a period enough to cause permanent injury to the crop and improve the boom in temperature of the air. Thermal stress is a composite property such as strength, boom length and charge air temperature. If severe thermal stress in the plant canopy plus drying air, size greater stomatal closure and reduced transpiration rate. If the warm pressure plus the water pressure, which can lead to increased root aggregation, if you want to reduce the efficiency of plant water uptake. If the pressure may begin to water can be found in the root is increased to increase, with perseverance the water pressure point especially in the presence of warm stress increase will reduce the common root.
