At present, the spring maize in the Huang-Huai-Hai area gradually enters the heading stage, and the summer corn is the key period for the formation of yield. According to the agricultural dispatch of the Ministry of Agriculture, the sown area of ​​corn in the Huang-Huai-Hai region this year is 158 million mu, an increase of 2.58 million mu over the same period of last year. Among them, the sown area of ​​corn in Anhui and Henan increased by 1.35 million mu and 105 million mu respectively over the previous year. The overall growth of corn is better than last year, which is equivalent to the average level. However, local areas suffered from severe weather such as droughts, floods, typhoons, and hail, and the task of field management in the later period was arduous.
It is widely reported that the quality of corn sowing this year is relatively high and the weather conditions are generally favorable. The seedling growth is better than last year. Summer mechanization of the summer harvest in Shandong has a high degree of mechanization, corn planting progress, high quality, the basic realization of the appropriate sowing, coupled with the end of June, the province's general rainfall, basically reached a broadcast all seedlings. The summer maize area in southern Hebei is in the big bell mouth period, and the northern spring maize area is entering the heading stage. The corn grows robustly and grows gratifyingly. Henan Province completed the summer corn planting before June 22 (summer solstice). The coverage rate of high-quality, high-yielding maize varieties in the province reached 100%, and the planting area of ​​major maize varieties such as Zhengdan 958 and Yudan 20 accounted for about half of the corn area in the province. The planting period of Anhui corn is 5-7 days ahead of last year. The sowing date is appropriate. In the middle of June, rainfall is sufficient and the emergence density has increased. Since the festival began, rainfall in most areas has been moderate, which has promoted the upgrading and transformation of the seedlings. At present, the overall growth of the seedlings is good. The percentage of one type of seedlings is 58.6%, which is 2.1 percentage points higher than the jointing period.
Since late June, Huanghuaihaixia corn planting area has suffered two A. tumida damages. Localities attach great importance to and take measures to actively launch the people to carry out prevention and control actions, and the harmful trend has been effectively curbed. According to preliminary statistics, local governments have adopted measures combining specialization and prevention with group prevention and group management. The total area of ​​prevention and control has been 50.82 million mu, which is 1.58 times of the area. Repeated fields such as Shandong and Hebei have generally been controlled twice or more. Contains the pest damage trend and better safeguards the safety of corn production.
Due to drought-resistant sowing and inconsistent sowing dates, some plots were not neatly emerged, with large differences in seedlings and unbalanced growth. In some areas, diseases and insect pests tended to be heavy and field management tasks were aggravated. In particular, at present, the Huanghuaihai region has entered the main period of “seven counts and eight risesâ€. The situation of droughts and floods varies across the country. The task of fighting against disasters and harvesting is arduous, and the management of the later period is more difficult. In order to ensure the corn harvest in the Huang-Huai-Hai area and strengthen the foundation for autumn grain production, the Ministry of Agriculture will further strengthen work supervision and technical guidance and implement field management measures.
One is scientific watering, drought protection and autumn. At present, it is the critical period for corn growth and water demand, and it is particularly necessary to prevent the occurrence of “card neck droughtâ€. The Ministry of Agriculture will organize experts and technical personnel to strengthen technical guidance, timely watering and scientific watering according to the law of water demand of corn, soil moisture content, and production targets, and try to pour as many pours as possible on the drought-bearing land, and strive to pour more than one acre of land. More than one mu of seedlings. At the same time, vigorously promote drought-resistant water-saving technology and strive to improve the utilization of water resources.
The second is due to seedlings, formula fertilizer. Promote popularization of soil testing and formula fertilization technology, so that the production of land to produce, to produce fertilizer, scientific fertilizer. Focus on the development of good corn leaf fertilizer, large bell-mouth fertilizer and other special fertilizer application.
The third is to strengthen forecasting and do a good job of prevention and control. Adhere to both drought and drought, pay close attention to weather changes, strengthen the guidance of agricultural disaster prevention and reduction, timely release warning information, and strive to mitigate disaster losses. Strengthen the monitoring and forecasting of pests and diseases, adhere to prevention, and prevent and control the disease scientifically so as to ensure early prevention and timely extinguishment, and comprehensively control hazards. Focus on the prevention and control of diseases and pests such as corn rough dwarf disease, corn borer, aphids, and rust.
The fourth is to strengthen supervision and do a good job of services. The Ministry of Agriculture will organize and carry out the “National Grain Production and Production Acceleration Action†inspection and inspection, check the implementation of local actions, urge local governments to implement field management measures, strengthen technical guidance services, and do a good job of creating high-yield demonstrations. At the same time, it will also timely summarize the good experiences and good practices of various places and arrange the harvesting work as early as possible to ensure that Feng receives the hand.
