Every year in the rainy season, regional heavy rainfall will occur in the north and south rice regions of our province, and local areas will accumulate disasters. In particular, rice planted in low-lying paddy fields is partially covered with rice. After flooding, rice roots and leaves were severely damaged. The normal physiological metabolism and stress resistance of the plants were severely attenuated, and the number of total seedlings was severely reduced. If timely and effective management of paddy fields cannot be achieved after heavy rainfall, it will inevitably lead to a significant reduction in production, or even an imperfection. Therefore, it is necessary to take scientific remedial measures in time after heavy rainfall in order to raise roots, protect leaves, and promote pupa as a goal, prevent and treat diseases and pests, increase the percentage of spikes, and increase grain gain. The production and quality of Enzyme preparations produced by plants are unstable due to the influence of growth area, season, climate, etc. The enzymes produced by animals are mainly extracted from the glands of slaughtered livestock, and the source is limited; only enzymes produced by microorganisms can meet the needs of any scale, with high yield and stable quality. Microbial enzyme preparations can not only replace the main types of animal and plant enzyme preparations with the same performance, but also produce high-temperature-amylases that act as catalysts at 100°C and detergent proteases that act at pH 10-12. In the 1940s, the microbial enzyme preparation industry developed rapidly. At present, the production of enzyme preparations is mainly based on deep fermentation, supplemented by semi-solid fermentation, and the ability of the strains to produce enzymes has also been greatly improved. The immobilized enzyme and immobilized cell technology developed in the 1960s and 1970s enabled the enzyme to be used repeatedly and continuously reacted, and its scope of application was also expanded. At present, in addition to the food and textile industries, microbial enzyme preparations are also used in daily chemistry, chemicals, pharmaceuticals, feed, papermaking, building materials, biochemistry, clinical analysis and other aspects, becoming an important sector of the fermentation industry.

Drainage as soon as possible to eliminate field water is an urgent task to restore rice growth after heavy rainfall, and it is also the most effective remedy. However, it should be noted that if high-temperature sunny weather is encountered after heavy rainfall, the water in the field cannot be drained once, but a layer of water of about 3 cm in depth must be kept to prevent the evaporation of high-intensity foliage and cause plants to lose water and die.
After removing heavy dirt from the leaves, a layer of soil is often attached to the rice leaves, which will block the stomata of the leaves and affect the photosynthesis. When the sun rises at a sunny day and the leaves turn white, you can use the rope to pull up on the leaves to shake off the mud on the leaves, and the leaves are green.
As early as possible, applying top-up fertilizer, water, and fertilizer supplements is a successful anti-disaster experience accumulated over many years. During flooding of rice, the vegetative organs are damaged to varying degrees. After the drainage, the plants need a lot of nutrients for their recovery and growth, and more fertilizer is lost after drainage. Therefore, according to the seedlings, timely recovery of fertilizers should be applied. Regeneration of fertilizer is generally applied 3 days after drainage. Fertilizers are mainly available nitrogen fertilizers, topdressing 8 to 10 kg of urea per acre, and applying potassium fertilizer, potassium chloride 7.5 to 10 kg per acre can be topped up. Potash fertilizer can not only enhance Rice resistance to lodging and disease resistance can also improve rice quality. In paddy fields with short flooding time and light damage, the amount of fertilizers may be less; in paddy fields with long submerged periods and heavy damage, multiple applications must be made, but methods must be applied lightly to prevent over-application of fertilizers to cause injury. When applying top dressing, you can spray high-efficiency foliar fertilizers to promote rapid plant growth.
After strengthening the water slurry management and drainage, on the basis of the sedimentation of the floating mud in the paddy field, adhere to the principle of dry and wet, intermittent irrigation of fresh water, both to maintain the ventilation of the soil and enhance the vitality of the roots, but also to meet the water needs of rice seedlings.
