2. Timely soil. Affected by stormwater, strong winds and other factors, the land that has fallen on the ground must be immediately cultivated and straightened according to the actual situation. Stems generally do not need to take remedial measures, so when the weather improves, it will automatically return to its upright state after a period of growth; the roots must be lifted immediately after the rain, and when they are raised, the stems and the ground must form a 30 to 50 degree angle. The roots of the corn are well-cultivated with earth, and the use of down-to-earth is practical; the stems are generally difficult to recover; the lighter lands are not easy to take rescue measures, and they can be allowed to grow naturally. For lands with severe stem folds, we must pay close attention to other types of crops. Fall crops to reduce losses.
3. Early application of Miao Fei. For fields that have been flooded for a long time and have serious waterlogging hazards, timely application of Miao Fei should be carried out. Large flutes can be topdressed with urea. Spraying high-efficiency foliar fertilizers and root-reinforcing agents at the same time as fertilization promotes transformation of seedlings, promotes root development, and promotes the restoration of growth. We promptly increased the availability of available nitrogen fertilizer to the plots that were sown late, drought and weak growth during the seedling stage.
4. Control pests. Due to field water accumulation, plant damage, soil moisture saturation, and high air humidity, it is easy to cause various diseases. For the emergence of pests and corn fields, to symptomatic treatment, spraying once every 10 days, a total of 2 to 3 times the drug, can control field pests and diseases. At the same time, we must strengthen observation in the field and remove weeds in a timely manner. This can effectively prevent the occurrence and spread of the virus, and early detection and timely removal of diseased plants to bring out the field treatment.
5. Weeding and weeding. After the rain, due to the large moisture content in the soil and the high temperature, the growth rate of weeds is obviously accelerated. If grass weeds are not cleared in time, it will cause grass shortage. After the heavy rain, severe weeds should be timely sprayed with herbicides for stem and leaf treatment, and can also be cultivated and weeded to ensure normal corn growth.
