What to do after the latest rice flood disaster
Rice is an important food crop in China. Rain Water is abundant in the south. During the annual Meiyu season, rice is often flooded. Once flooded for more than 48 hours, it is very likely to lead to the death of the whole plant. So what should we do after the rice flood? Let's take a look at the detailed introduction.
1. Drainage and seedling exposure
After the withdrawal of water, it is necessary to timely drain, dredge ditches, clear silt and reduce stains, so as to make the flooded seedlings come out of water as soon as possible and enhance respiration. It also depends on the weather when the seedlings are drained. If it is cloudy, the water can be emptied at once; if it is sunny, a shallow water layer should be retained in the field to meet the water needed for transpiration of the seedlings, avoid dehydration and death, and wait for the seedlings to recover. Restore growth in the drained open field. For those who are flooded but the flooded time is not long and the plant is not dead, the leaves should be washed in time, and the mud of the leaves should be washed, and the lodging seedlings should be righted to promote their normal growth.
2. Fertilization
For early rice at booting stage, after timely drainage and cleaning of leaves, potassium dihydrogen phosphate solution should be sprayed according to the seedling stage to strive for large panicle, increase grain weight, maintain yield, and prevent diseases and insect pests. For the middle rice in the tillering stage, the leaves should be drained and cleaned in time, 2.5 kg of urea and 4 kg of potash fertilizer should be applied in shallow water to promote its recovery as soon as possible, pay attention to the outbreak of diseases and strengthen prevention and control. For late rice seedlings, the whole field should be ploughed in time, and 5 kg urea per mu should be applied after shallow irrigation, which can promote the seedling recovery and root growth and improve the survival rate.
3. Replanting and replanting
For the land that is flooded and lack of seedlings, it is necessary to replant in time to ensure that the seedlings are complete and reduce the loss, and if most of the seedlings die, other plants should be replanted in time according to the growing season and temperature. Those who can continue to grow rice should be rescued in time, while those who cannot be rescued should be changed to dry crops in time, such as potatoes, mung beans, shepherd's wheat, and so on, so as to avoid land waste.
The above is the introduction of what to do after the rice flood disaster. I hope it can help you. If you want to know more about it, please follow us.
