When is the summer heat in the twenty-four solar terms?

The summer heat in the twenty-four solar terms is usually from July 6th to July 7th and 8th every year. The weather is mild in summer, not very hot. It's getting hotter, but it's not the hottest.

Before and after the summer heat, agricultural production was mainly busy with field management except winter and spring wheat harvesting in Northeast China and Northwest China. Early rice is in the late filling stage, and early-maturing varieties should be harvested before the heat, and the field should be kept dry, moist and dry. Mid-season rice has entered booting stage at jointing stage, so it should be topdressing panicle fertilizer according to its growth situation to promote large panicle and more grains. The single-season late rice is tillering, so tillering fertilizer should be applied as soon as possible. The second night seedlings should be well protected against pests and diseases, and "marriage fertilizer" should be applied 5-7 days before planting.

"It's hot in summer, and the cotton keeps pruning." In most cotton areas, cotton began to blossom and boll, and its growth was the most vigorous. At the same time, old leaves should be pruned and raked in time to coordinate the distribution of nutrients in plants, enhance ventilation and light transmission, improve the microclimate of the population and reduce the shedding of buds and bolls. High temperature in midsummer is the season when aphids, red spiders and other pests flourish, and timely prevention and control of pests and diseases is another important link in field management. "
