In the near future, Anhui should do a good job in field management of flooded crops, timely investigation and seed replanting

Anhui Province Huaihe River region appears concentrated heavy rainfall July 8 to 14, the heavy precipitation mainly in the area south of the Huaihe River, Anhui Province, the region is the main producing areas of rice and cotton, as well as abundant water resources along the river, Aquaculture is also one of the main sources of income in rural areas. The precipitation process lasted for a long time and the intensity was high, which led to flooding of farmland along the Yangtze River, especially along the western part of the Yangtze River. The river flooded and some lakes and reservoirs overflowed, causing serious economic losses to agricultural production.

According to the information office of Anhui Province Relief: As of July 17 when 12 preliminary statistics, the province's 12 cities and 65 counties months (cities, districts), 501.76 one thousand hectares of crops affected area (753 acres), of which one thousand hectares of crops area 69.82 ( 1.05 million mu) agricultural losses of 2.585 billion yuan. According to the Bureau of Fisheries Information: destroyed the province, flooded pond 209500 acres, destroyed 377,500 acres of pen farming area, destroyed the size of the cages 157,880 square meters (Anqing City, eel pond cages 105,720 m2), escapes into 30,600 tons of fish, fish There are 9650 tons and 9500 groups of broodstock . Infrastructure such as production houses, ponds, fishing boats, fishing gear, and electric power were also damaged to varying degrees, and the economic loss of fisheries reached 739 million yuan.

At present, cotton in Anhui Province is in the flowering and belling period. Cotton has a weak resistance to waterlogging disasters. Under normal circumstances, the flooding is less than 24 hours. After draining, the cotton plants will be slightly wilted, the young buds will fall off, the leaves will be yellow, and there will be no dead seedlings. If the remedial measures are timely and appropriate, Cotton recovers faster and has less impact on yield. However, the flooding time is more than 48 hours. If it is under strong sunlight, it will easily lead to the lower rot and blackening. The upper part will show permanent wilting, and all will die after retreating.

Since July 8, Anhui Province along the Yangtze River cotton-precipitation of long duration, high-intensity, wide range, cotton water seriously, because most rivers and ditch pond high water, poor drainage of farmland, some cotton water time over two days Will cause no harvest. At the same time, heavy precipitation causes the young buds to fall off, affecting the later production; in the south, as much as 7-10 days of rainy weather, the flooded farmland has a large environmental humidity, and the temperature and high humidity are easy to cause disease prevalence.

Heavy precipitation caused the rice fields to flow or be washed away, soil fertility was seriously lost, and the rice on both sides of the river suffered a devastating impact. At the same time, the low-lying fields were not well drained, and some paddy fields were not flooded for several days. At present, the rice in the first season is in the stage of tillering to jointing, and the early stage is in the heading and filling stage. The continuous heavy precipitation process caused the farmland to be in a state of continuous flooding, resulting in a decrease in the number of acres of stems in some rice fields, and the death of some low-lying fields. In addition, for a part of rice that was transplanted late and rooted unsteadily, especially in the field, the seedlings were pulled up and washed away under the combined action of running water and buoyancy. For the early rice in the stage of flowering and filling, it suffered from " rain washing " , which could not be pollinated normally, and the empty granules increased significantly. At the same time, due to insufficient sunshine, the stems of the plants were weak, and the early rice showed a large area lodging, which affected the normal filling of rice. The weight of the grain is reduced.

At the same time, the flood disaster caused many floods and overflows in the valley ponds along the western part of the river. Some pond ponds were damaged seriously, the breeding facilities were seriously damaged, and the pond fish species and adult fish escaped a lot. The fishery losses are serious.

According to the forecast of the Anhui Meteorological Observatory, there will still be more obvious precipitation processes in the northern part of the province in the next three days. From 21 to 24 , the province is mainly cloudy to sunny. At present, the seedling quality of the affected crops is generally weak, and there are different degrees of damage, coupled with poor farmland environment, it is easy to induce various pests and diseases. It is imperative to seize the current favorable weather situation, clean up the farmland environment in time, restore crop growth, and replant in time. Suggest:

Grasp the favorable weather situation and do well in the field management of flooded crops

　　 1. Discharge and dehumidification in time. Long-term accumulation of water in farmland is likely to cause soil compaction and loss of fertility, which affects the growth of crop roots. Therefore, for orchards and vegetable gardens with more water accumulation, drain the ditch as soon as possible, dredge the ditch in time, eliminate the accumulated water in the field, and reduce the soil moisture of the farmland.

　　 2. Do a good job in pest control. It is necessary to timely support the plants in flooded crops, increase the permeability of farmland, clean the leaves and sediments, remove the residual diseased leaves, and prevent the breeding of pathogens; timely check the incidence, the diseased fields should be cleaned up. The leaves are removed from the field, and the therapeutic pesticides for the counterparts are selected. The non-infected fields are protected by a prophylactic pesticide spray.

　　 3. Strengthen the field tube to promote the recovery of crops. Carry out seedlings and seedlings, cultivate and cultivate soil, and increase the application of quick-acting fertilizers to promote the transformation of flooded crops.

Rejecting the field, replanting in time to make up for the flood damage

　　 1. The first time to replant the live late rice. According to the rice temperature requirements, the average daily temperature of the late japonica rice is not lower than 22 °C (indica rice 20 °C). Resource-rich southern region along the heat, summer and autumn daily average temperature of 22 ℃ usually after September 20. The region July 20 - September 20, more than 10 ℃ accumulated temperature of more than day 1550 ℃, live in time to meet the conditions of heat rice sowing to heading, so along the river terraces alternative crops precocious rice germination using technology to broadcast live Scientific management under the guidance of relevant agricultural technology departments to ensure safety and reduce agricultural losses.

　　 2 , make up ( change ) crops with short growth period, such as early maturing summer corn, fresh corn, vegetable soybeans, fresh autumn peanuts, autumn sowing watermelon.

　　 3 , in areas where conditions can be changed to grow vegetables. Suitable vegetable types are: cucumber, tomato, kidney bean, water spinach, Chinese cabbage, Chinese cabbage, early cauliflower, autumn radish, and the like.
