At present, the late rice enters the middle and late stages of growth, and the requirements for pest control and water treatment must be scientifically managed. Farmers' management of this time is easily overlooked. Now the production of late rice should pay attention to the following management.

1. Management of water: The water layer should be kept 2 to 3 cm in the field during heading and flowering, in order to facilitate normal flowering and pollination and fertilization of rice, especially when cold air comes to the wind or cool down. Before the rain is heavy, the water should be poured in time. Adjust water temperature and mitigate low temperature hazards. After the rice is in the same stage, it is dry and wet, mainly wet. The water is kept for 4 to 5 days, and the water is allowed to dry naturally for 1 to 2 days before the water is refilled. In the middle and late stages of grouting, the main part is dry, and the water is kept for 2 to 3 days. After the water is naturally dried, the water is refilled 2 to 3 days until the week before harvest.

2, pest control: This period is mainly to prevent migratory rice planthoppers; sheath blight, rice blast and other epidemic migratory pests and diseases. Use the right medicine to achieve scientific prevention. In the rice planthopper, pymetrozine and nitenpyram were used for the control; the sheath blight was treated with oxazolol, benzophenone and propiconazole; and the rice blast was treated with Fuji No. 1. Pests and diseases are mainly prevention and comprehensive prevention.
