Extended data:
The basis for saying that June is not hot and the whole grain will not bear fruit: Take rice as an example: June is the small potato period, which is the tillering stage of rice, and low temperature is not conducive to the emergence, growth and booting stage of rice. Low temperature will cause rice stalks to be soft, prone to lodging and disease. Low temperature will make the accumulated temperature in rice growing period insufficient. Delaying the booting stage of rice can not lead to heading, flowering and fruiting on time.
Since it is not hot in June, there is naturally a reason. The reason why it is not hot in June is that it has been raining for a long time. Pests such as rice blast, bacterial blight, rice leaf roller and yellow rice borer are prone to occur in long-term rainy days, which seriously endanger rice yield and quality.
