At this time, in the flood season, corn fields are flooded or lodging. How should they be managed? Flooded land, drained as soon as possible. After heavy rainfall, if there is accumulated water in the corn field, it should be as soon as possible to find ways to discharge, reduce the humidity in the field, and timely top dressing. After heavy precipitation and flooding, the fertility of the soil is taken away by rainwater, and topdressing can promote plant growth. The use of urea 0.5% and potassium dihydrogen phosphate 0.2% can be used. After completely dissolving and mixing, make use of sunny days after the rain, spraying the top dressing with foliar spray, which requires continuous spraying twice, with an interval of 7 days. For corn in pollination and flowering season, it is necessary to replenish the panicle fertilizer and apply 10 kg of urea per acre. Heavy rain may also affect the flowering and pollination of corn, resulting in corn tipping, lack of grains, and planters can use artificial pollination. At 9-11 a.m. or 4-6 p.m., gently shaking male flowers for pollination. Lodging corn, it is necessary to take the classification of management measures: 1. For lighter lodging (corner between the stem and the ground angle greater than 45), generally do not take straightening measures, so that with the growth of natural upright. Corn is lodging before the booting stage and it is immobile and cannot be helped. Lodging naturally within 3 days can be folded. The stem sections near the ground quickly take root. As the root volume increases, there will be no secondary lodging and no effect on the yield. Once raised, it will inevitably be rooted, and will no longer take root. It will not only affect production, but it will be prone to secondary lodging. 2. For corn that has serious lodging, especially corn, timely artificial support should be carried out, and soil should be cultivated in the roots. Due to the fragility between the first and second internodes of the base of the corn stem, it is necessary to prevent breakage and increase the root injury during erection. The method of straightening should be coordinated by two people. One is to straighten up, and one is to cultivate the earth. The height of earth should be 7-8 cm. The corn is laid down after heading. Do not cut the leaves. Can only lift up the bar. When you tie the handle, tie the ear of the fruit to the rope. Do not prick the ear to the bottom. The best number of ties is 3-4. There must be no more than 5 trees, more than 5 trees, and even heavy rain breaks easily. When you tie your tie, you must tie it tightly. Do not loosen it. The time for the tie required the day to plunge on the day. Can not exceed 3 days. After three days, they can no longer help, but also help reduce the root cause. 3. For corn with broken stems, break the broken plants out of the field as soon as possible to avoid rot, affecting normal plant growth. For severely broken plots, it is necessary to pay close attention to clearing plots at the time of farming and replant vegetables such as radish and cabbage that have a short growing period. Attention to pest control. After corn lodging, diseases often occur, such as corn leaf spot, brown spot, and corn borer, etc., they must be controlled in time; farmers can also cut empty stalks and diseased plants, spray foliar fertilizer and potassium dihydrogen phosphate to increase The ground is warm and airy, accelerating the maturity of the grain. For foliar diseases, 70% thiophanate-methyl 800-fold or 50% carbendazim 500-fold or 75% chlorothalonil 300-fold can be sprayed, once every 7-10 days, with 2-3 sprays. Times.
