Summer agricultural activities in the twenty-four solar terms

1, in midsummer, the weather is in the hottest period, and all kinds of warm-loving crops are in the fastest growing season. Cotton in Northeast China and other places has entered the flowering and bolling stage, and soybean has reached the flowering and fruiting stage. At this time, at the peak of crop water demand, attention should be paid to irrigation and water replenishment.

2. In case of drought in the morning, cotton will drop flowers and spit bolls, and soybean will drop pods. Rice, corn and sorghum in Northeast China and North China have headed and blossomed. Mid-season rice in the Yangtze River basin heads and spring corn matures. At this time, in addition to the hot weather in the north, the rainy season has arrived, and it is easy for the south to flood ahead of time. Climate change is also the most intense period, and different degrees of lightning and hail will appear one after another.

3. For the areas where double-cropping rice is planted in China, the most intense, scorching sun and high temperature "double grab" in a year has begun. As the saying goes, "Early rice grabs the sun, late rice grabs the time", "If you don't mow the grass in summer, you will lack a reed a day". Timely harvesting of early rice can not only reduce the harm caused by wind and rain in the later period, but also ensure high yield and harvest, and strive for sufficient growth period for double-cropping late rice.

4. The agricultural song of the great summer heat wrote: The great summer heat is in midsummer, and the annual temperature is high. When the flood occurs, the task of flood control and drainage is urgent. Catch up with spring and summer crops and seize the opportunity to control pests and diseases. Corn is artificially pollinated, and the grains above and below the ear are uniform. We must pay close attention to cotton management, repair, chase and control pests, hoe the ground frequently, and top it by stages, no later than the end of the month. It is a good time to accumulate fertilizer and make green manure. In rainy season, trees will continue to be planted, scattered pieces will be planted together, early-maturing apples will be picked, and red Sophora japonica will be harvested. High temperature can prevent heatstroke of livestock and treat sunburn (disease) and rotten hoof (disease). The fish lacking oxygen in the water flooded the pond. Before sunrise, the head floated, alum water splashed with salt water, and the fish in the whole pond subsided. Therefore, in the midsummer season, the most important thing is to grab the harvest and sow.
