On the morning of August 2, when the sun was shining like fire, experts from the Institute of Crop Science of the Chinese Academy of Agricultural Sciences, at the request of farmers, opened a "field classroom" for crop recovery and production after the disaster in a corn field with only more than 100 mu left in Haojie Village, Xigang Town, Qixian County.

From July 17 to 23, heavy rainfall caused serious damage to farmland in Hebi City and Huaxian County in Anyang City. In order to help farmers reduce losses, on July 30, the Institute of Crop Sciences of the Chinese Academy of Agricultural Sciences set up a team of experts, and 9 experts rushed to the hardest-hit Counties of Xun, Qi and Huaxian to go deep into the fields to help farmers restore agricultural production.

"The 50 acres of fertile land I contracted have all been flooded, and the peach trees, corn, peanuts, and soybeans planted do not know whether they can survive or not, so what should I do next?" With only hope, 60-year-old villager Jie Chaoju hurriedly asked the experts for verification. She said: "When you come, we have hope, and we can save as much as we can, or we will look sorry." ”

Only five steps away, the farmland road was still watery on both sides, and the dead corn leaves were lying on the water, looking at a desolate silence.

The 20 acres of corn of Sun Jihui, the older farmer in the village, were also all flooded. He painfully told the experts that Haojie Village had a total of more than 1,700 mu of arable land, 1,600 mu of land that had been affected, and only more than 100 mu of corn were still alive, soaked in water for 10 days, and now individual corn stalks have also withered.

The four experts of the Institute of Crop Sciences of the Chinese Academy of Agricultural Sciences did not say a word, drilled into a one-person high corn field, one plant after another, roots, leaves, stems, for every problem that may affect the growth of corn, they all discussed in the field, and put forward feasible suggestions for reducing losses.

The soil was soft and muddy, and the experts' shoes were covered with mud and could not be cleaned. Wang Keru, a researcher at the Institute of Crop Sciences of the Chinese Academy of Agricultural Sciences, encouraged the affected farmers: "Don't be pessimistic, I can save 60% of the yield of these corns that are still alive." Hearing this news, the villagers' eyes lit up.

Wang Keyu is an expert in the research of high yield and full mechanization of corn, he said, the land here is a high-yield area of corn, take some measures or can be more harvested, the weather is restored to clear, it is good for farmland that has no water. 2% of the plants in the field can not be saved, and to maintain 60% of the yield, it is necessary to prescribe a prescription for the farmland.

"The root system is declining, and the field should be fertilized." Brown spot disease has appeared on the leaves, etc., and it is necessary to prevent diseases and insects. Wang Keru said that pesticides such as Kangkuan can be used to enhance the photosynthesis of corn, add some urea and potassium dihydrogen phosphate, and spray with drones, which also has certain benefits for pollination. But do not pay attention to the concentration, the nozzle to use divergent type, the time to choose after 8:30 a.m., before 12:00 noon, after 20 or 30 days, use this method to repeat, the later also pay attention to the autumn drought during the irrigation must be small.

After listening to the expert's words, Sun Xi, a villager who had just arrived at the scene, pulled the expert and ran to his 20-acre fruit tree garden. He said his fruit trees had been flooded for 12 days, and now there was still about 30 centimeters of water, and new shoots had emerged from the branches, which needed to be supported by experts. "We must seize the time to save ourselves and drain the accumulated water." Wang Keru said, recommending the contact information of the fruit tree expert stored in the mobile phone to Sun Xi. That night, Sun Xi received advice from fruit tree experts.
