Does the temperature exceed 35 degrees affect rice? How to deal with it?

Rice is extremely sensitive to temperature in bud stage and heading stage, and the optimum temperature is 25 to 30 degrees Celsius, which will have adverse effects. When the high temperature weather lasts for more than 35 degrees at booting stage, the flower organs of rice will be underdeveloped, the pollen will be stunted and the vitality will decrease. If sustained high temperature weather above 35 degrees is encountered during heading and flowering, it will cause heat damage, which will affect pollen crushing and pollen tube elongation, resulting in failure to fertilize, forming empty shells and flowering without fruit.

Generally, potassium dihydrogen phosphate, brassin and boron fertilizer are sprayed to improve the stress resistance of rice.
