This period is the key to achieving high yields, and water and fertilizer management and pest control in the fields are crucial.
1, scientific management of water. The heading period should be kept 2 to 3 cm shallow water irrigation, adjust the temperature, increase air humidity is conducive to flowering pollination. Within 20 days of heading, intermittent water supply and water and gas exchange were used to achieve the purpose of cultivating air with roots and protecting leaves with water, which will help promote grouting and prevent premature aging.
2, spray grain full.

3, prevention and control of pests and diseases. It focuses on the prevention and control of pests and diseases such as stem borer, rice leaf roller, rice planthopper, sheath blight, and rice blast disease. Comprehensive use of agricultural control technology, physical control technology, biological control technology and chemical control technology. According to the county plant protection station pest information, grasp the appropriate control period, dosage and application methods to ensure the best control effect.
