What are the three stages of summer heat?

The three stages of summer heat are warm wind; Second, wait for crickets to live in space; Three waiting eagles began to collect birds.

Warm wind arrives: After the slight heat, the breeze is hard to find, and the earth seems to be frozen by the heat wave.

Second-class cricket lived in the house: it was extremely hot, and cricket left the field, hiding under the corner of the courtyard, looking for rare shade.

The third-class eagle began to fly: the ground temperature was too high, and the eagle flew high, and began to explore new areas with cooler altitude.

Agricultural activities during the summer heat

Early rice and spring corn are in the filling stage in summer solar terms, which is the key period of grain formation. Agricultural activities aim at preventing premature aging, promoting grain filling and increasing 1000-grain weight. Attention should be paid to prevent high temperature ripening and drought disasters in production. In case of high temperature or drought above 35℃, irrigation measures can be taken to improve the field microclimate, or foliar fertilizer can be sprayed to improve the stress resistance of crops.

Mid-season rice and summer corn are in the transition period from vegetative growth to reproductive growth, which requires a lot of water. Early water cut-off in middle rice field is not conducive to effective tillering formation and young ear differentiation, and neck drought may occur in summer maize, which will seriously reduce production.

Cotton is in the flowering and bolling stage, and late rice is in the seedling stage. It is necessary to keep the ditches unobstructed to prevent waterlogging. In addition, good weather conditions in summer are also favorable opportunities for field operations such as pest control.
