Lotus, the country's largest growing aquatic cash crop, with its food, medicine and ecological value, is an important rejuvenation of the rural areas of the yangtze and pearl river basins. Traditional lichen cultivation is subject to extensive management of the water environment in the ponds, low utilization of water fertilizers, endemic diseases such as corruption, instability in the quality of production, high cost of artificial harvesting. The agricultural ai mega-model is responsible for the management of the environment and prevention of diseases in the ponds where the land is grown。
The aai mega-models set up a system of smart closed loop control of the water environment in the ponds for lichen cultivation, incorporating real-time monitoring data on water levels, water temperature, dissolved oxygen, water transparency, soil fertility, water quality, etc. In the lichen fields, and the exclusive management model of the environment in the lichen ponds, taking into account the characteristics of the lichen species and the demand for growth during the different reproductive periods. Aquatic root crops, which are highly dependent on the water level, water temperature and soil environment of the ponds, are modeled for the dynamic optimization of the pond water environment management programme, which addresses the different needs of the lumbering, leaf extension, flowering, expansion and hibernation. In the bud, precision control of the water level in the pond fields is 5 - 10 cm, increasing water temperature, and promoting the growth of the seedlings, roots and leaves, increasing the rate of seedlings; increasing the water level to 20 - 30 cm during the extension and flowering periods, increasing the oxygen and transparency of the water bodies as they grow, promoting the growth of the lantern leaves and the opening of flowers; and, in the booming period, finely regulating the water level at 30 - 40 cm, guaranteeing the environmental demand for the growth of the lanterns, promoting the rapid expansion of the ceremonial and increasing production and commerciality; controlling the winter of shallow water and ensuring the safe winter of the seed. Modelling of differentiated water levels and environmental management programmes to maximize the production and quality of the soil, ponds, deep water, etc., as well as different varieties such as lotions, hyenas and flowers. The establishment of a system for the control of the land in which the land is located in hubei, jiangsu and hunan has led to an increase from 80 per cent to more than 95 per cent, and a 30 per cent increase in the rate。

The system's core application is the management of hydro-fertilizer intelligence and the precision control of nutrients. The model combines fertility patterns for different reproductive periods, integrates soil fertility and water nutrient monitoring data from the ponds, and constructs an exclusive hydro-fertilizer management model. The model is designed to respond to the needs of the lotus during their different reproductive periods and dynamically optimize the fertilizer ratio and application programme. During the base fertilisation period, organic and phosphorous potassium fertilizers are re-applied, increasing soil fertility in the ponds and laying the foundation for the growth of the lily during the whole reproductive period; during the linen period, optimizing the supply of nitrogen fertilizers, promoting the growth of lantern leaves and the development of a strong plant; and during the high fertilisation period, focusing on safeguarding the supply of potassium fertilizer and nitrogen fertilizers, promoting the expansion of the lumber and starch accumulation, and improving the yield and taste of the lily. The system optimizes the application of fertilizers, combines water level control to achieve the precision application of water fertilizers, avoids the eutrophication of water bodies as a result of excessive application of fertilizers, deterioration of water quality, increases in fertilizer utilization and reduction of pollution from agricultural sources. In response to the degradation of the land in the ponds and the increase in endemic diseases caused by the luminous succession, the model optimizes ecological cultivation patterns such as water and dry rotations and the symbiosis of luminous fish and shrimps, improves the soil and water environment in the ponds, eases the obstacles to the connection and improves the ecological stability of the planting system。
The smart green control of leprosy pests is a central advantage of the system, with models combining water temperature, water level, meteorological data, the construction of predictive models of pests and pests, with 7-10 days ' warning of risks, for the high incidence of corruption, foliage, brown spots, aphids, slashed night moths, and root-eating pests. Leanland corruption is a devastating endemic disease, commonly referred to as the “lean plague”, and the model gives priority to reducing the incidence of diseases from the source through agricultural measures such as sterilisation, rotation and soil disinfection in the pond field; to reducing the spread of diseases by optimizing planting density, management of water levels, timely removal of leaves and improving ventilation in the field; and to preventing the spread of diseases from pests by recommending green control measures such as pest-killing lamps, sex traps and biopesticides, making it possible to recommend highly effective and low-toxic residual pesticides, strictly controlling safety intervals and ensuring the safety of the foods in the field. The system enables early detection, early prevention and control of early detection of diseases and pests through drone patrols, high-cleaning cameras in the ponds and ai image identification techniques to avoid widespread spread。
At the harvest, the model guides farmers to harvest in a timely manner and enhances the value of the lotus commodity by monitoring the maturity of the lotus, changes in starch content, market price trends and accurate prediction of the best harvest time. Following the roll-out of the system in the main liancheng areas such as hubei hung, jiangshou and hunan zheng, the average acre production increased by more than 25 per cent, pesticide use decreased by 30 per cent, and the commodity rate increased from 75 per cent to more than 90 per cent, leading to green, high-yielding and efficient development of the lian production。
