Слайд 3
Слайд 4: Temperature is the most important climatic factor to be considered in agriculture production
Слайд 5: CROP TEMPERATURE NEEDS (the sum of active temperatures above 10°C)
Wheat — 1200—1700, Barley — 960—1450 ; Oats — 1000—1600; М illet — 1410—1950; Buckwheat — 1200—1400; Potato — 1200—1800. Corn — 1100—2900 ; Sunflower — 2000—2300; Cotton – 3000-3400
Слайд 7: The effect of temperature on the yield of grain
Слайд 8: T o prevent the plant from a low yield
C reate resistant crop varieties of high temperature; To use of resource-saving technologies
Слайд 9: Questions:
How does high air temperature influence on the yield in tillering period of wheat? How can we prevent a low yield of crops from high temperature?
