Due to the excessive rainfall, the drainage of the drainage in the ponds and canals is not smooth, and the water in the paddy fields cannot be drained, resulting in flooding of part of the paddy fields and heavy loss of soil fertility, causing damage to rice. The specific remedial measures are as follows:
1, grab the sunny harvest. Harvesting timely harvested early rice to prevent sprouting on the ear, grain weight decreased, poor quality of rice, yield decreased.
2, timely drainage and drop. Do a good job of clearing and dredging the Sangou of the field, and eliminate the water in the field in time. When paddy fields are drained, it should be noted that during the intense hot days, it is necessary to gradually reduce the row, retain the appropriate water layer, so that the rice seedlings gradually return to life; in the rainy days, the water can be drained once, which is conducive to the recovery of seedlings.
3, exposed seedlings washed leaves. For rice that has been flooded over a long period of time and has been flooded for a long time, the mud on the leaves must be washed in time after the water level drops to restore the normal photosynthetic function of the leaves and to promote the plant to restore growth.
4, timely fertilizer. Timely application of panicle fertilizer, or top-dressing. According to the situation of the seedlings per acre topdressing grain fertilizer urea 3 ~ 5 kg, potassium 2 ~ 4 kg. In the flag leaf extraction and filling period outside the root of potassium dihydrogen phosphate spray, with 75 to 100 grams per acre, watered 50 kg, spray 1 or 2 times.
5, shallow water intermittent irrigation. After heading, shallow water intermittent irrigation was used to enhance root activity.
6, timely control of pests and diseases. Insect and pests are generally severe in flooded rice fields and are the focus of prevention and control. In the end of July and early August, Jinggangmycin and other agents were used to control sheath blight 1 or 2 times, 3 to 5 days before the break, and propiconazole and fenproconazole (Ai Miao) were used to control rice smut. At the same time, it should promptly prevent and control the three generations of rice stem borers, rice leafhoppers, rice planthoppers and other pests.
7, timely replanting "early turn late." For drowned mid-season rice and late-season paddy fields, timely plowing and ploughing of the whole field should be adopted. Early and mid-maturing early-season rice varieties should be used to implement autumn planting. No-tillage precision can be taken to live, to strengthen the management of fertilizer and water and chemical weeding, spraying paclobutrazol three leaves at the same time, cultivating early-onset strong seedlings, put a good breeding frame.

cotton
First, highlight the "four snatches" and quickly restore the normal growth of cotton. One is to grab dark water to drain the dark water, so that the cotton seedlings as early as water, early dewatering; second is to rush to help Miao washing leaves clean; third is to loosen the loose soil. When the soil is cool and dry, it is necessary to loosen the soil in time, ridging and cultivating, reducing humidity, and promoting root development. The fourth is to grab the top shelf. In combination with cultivator loose soil, apply the appropriate amount of urea, while spraying fertilizer from outside the roots, do it on the ground and on the ground, put the seedlings up. For cotton fields with good foundation, more early fertilization, and strong growth of cotton plants, timely adjustment should be made to prevent the growth of cotton plants.
Second, to strengthen the autumn tube, Fumo loss Qiu Tao compensation. It is necessary to vigorously publicize the experience of winning the harvest of cotton in the disaster year as "winning in the autumn peach and expensive in the autumn." One is to increase flower and bell fertilizer and reapply fertilizer. With sufficient fertilizer to make up for the loss of early nutrients and to protect the nutrients needed in the late autumn peach. Particular attention should be paid to the application of potash fertilizer. Potassium fertilizer should be applied to the cotton field where the amount of potassium is insufficient in the early stage to prevent premature decline of the cotton plant. The third is to strengthen pest prevention and control to ensure that limited bells and rare peaches are no longer harmed by cotton worms.
Third, break the routine and do four delays. The first is to postpone the timing of application of the fertilizer to August 15-25. The second is to postpone the top-down time to August 10-15, making full use of the longitudinal growth advantage of cotton and increasing branches by long branches. The third is to postpone the spraying of insecticides to stop pests and strengthen the prevention and control of late cotton pests and diseases. The fourth is to delay the time of pulling stalks, implement a small plough race, and plant a set of cotton and rapeseed sowing in cotton lining. Try to get as much as possible to grow enough velvety and normal boll opening.
Fourth, set the late autumn crops, increase cotton field income. For cotton fields that have caused dead seedlings and ridges due to waterlogging, intercropping short stalked crops such as green beans and vegetables will increase income in cotton fields.
vegetables
First, prevention of mud in the mountains. Grab the rain gap. Assault clean up the three trenches outside the vegetable field, clear up the deepening of the inner three ditch, ensure that the rain stops dry, and no water is accumulated on the surface. For low-lying areas with high inland water levels, electric pump drainage will be organized to speed up drainage and lower groundwater levels. Gap and groove to promote the healthy growth of vegetable roots, reduce the occurrence of waterlogging and pests.
Second, due to vegetable chase fertilizer material. For the early period of low fertilizer input, the Meiyu period lost more, the vegetable population is too small, timely application of organic fertilizer and compound fertilizer, and promote the coordination of vegetative growth and reproductive growth.
Third, timely replanting and replanting. For some of the dead seedlings, lack of seedlings in the field, do a good job of fast-growing vegetable replanting, replanting work. At the same time, practical measures were taken to prevent rain, and the cultivation of autumn vegetables such as cabbage and cauliflower was organized.
Fourth, the high mountain areas in western Hubei should pay attention to the damage of the debris flow to the production of alpine vegetables, and take certain defensive measures to prevent secondary disasters; also organize harvesting of vegetables in the field and increase effective supply to large and medium-sized cities.
corn
1, timely earth upright. After the rain stops, it is necessary to straighten the corn plants, cultivate the soil on the base of the stem, and use the foot to compact it. This only takes 2 to 3 days to grow new roots and resume growth quickly, with less impact on production. In the jointing season, if there is a danger of heavy storms, as long as the degree of lodging does not exceed 45 degrees, natural growth can be restored after 5 to 7 days.
2. Severe lodging can be bundled in multiple plants. For the high-stalk corn varieties, multiple strains must be bundled. The specific approach is to propel 3 to 4 nearby corns together and bind them together so that the plants can support each other and avoid pressure and stacking, so as to reduce the damage, and help the grout mature and reduce the loss of production. Corn that is lodging or stem-folding before maturity should be raised in time to avoid affecting photosynthesis.
3, dredge the three ditch, remove water. After the rain, the gutters, gutters, and gutters should be dredged and the accumulated water should be removed to reduce the groundwater level and reduce soil moisture in the field. Especially in low-lying lands and paddy fields, due to poor drainage, it is easy to cause flood disasters. It is also necessary to dredge the Sangou.
4. Strengthen management and promote growth. It is crucial that the plant roots return to normal physiological activity as soon as possible after the disaster, in order to cultivate the soil in time, cultivating the soil, removing the hardening, improving the soil permeability, and restoring the root system of the plant as soon as possible. According to the extent of the disaster, it is also possible to increase the available nitrogen fertilizer to accelerate the plant growth. (Hubei Dangyang Agriculture 110 Zhu Liqing)
