Since May, most of the central and southern parts of North China, Huanghuai, Jianghuai and other places have less precipitation and higher temperatures. The drought has developed in some areas. Although it is conducive to the smooth summer harvest, it has an impact on the summer planting schedule and sowing quality.
Since May, the average regional precipitation in North China, Huanghuai and Jianghuai regions is less than 35 mm, which is less than 50% less than normal, and the least in the past 10 years (2002-2012). The temperature in the central and southern parts of North China, Huanghuai and Jianghuai is 1~2°C higher than normal, and some areas are 3~4°C higher. In June, there were 3 to 5 days of high temperature above 35 °C in the southwestern part of Hebei, most of Henan, and northern Anhui. The high temperature days in the central and western parts of Henan and parts of northern Anhui reached 5 to 7 days, and the temperature in some areas exceeded 40. °C.
Due to the persistently low precipitation in the above areas, the temperature is obviously high, the soil is rapidly degraded, and the drought in some areas has developed rapidly. The drought has caused insufficient water for summer planting in North China, Huanghuai and other places, which has affected the progress of summer planting and sowing quality to some extent. In some areas, soil shortage can not be planted, or seedling is slow after sowing, and the emergence rate is low, which affects the normal growth of seedlings.
The weather will continue to be sunny and rainy in the coming week, posing a threat to the emergence of summer crops.
It is expected that in the coming week, North China, Huanghuai, Jianghuai and other places will still be dominated by sunny and hot weather. From 18th to 23rd, most of the north and south of China and Huanghuai will have 3 to 5 days of high temperature above 35°C. the weather. Continued high temperature will aggravate soil loss, which may lead to further expansion of the drought in the above areas, and the intensity will further increase. The continuous development of drought will pose a serious threat to the emergence of summer crops.
According to the weather situation, remind everyone to pay attention to:
First, the summer sowing area should do a good job of water source dispatching, smashing and sowing, and the plots that have been planted should be timely watered to ensure that the seeded seeds are normally emerged.
The second is to strengthen the management of seedlings, timely check seedlings, replenish seedlings, and timely irrigation according to lyrics and seedlings to ensure that Miao Qi Miao Zhuang.
