(1) Strengthen the management of greenhouses and nurture strong and prosperous people. For this year's low-temperature, high-sorghum and other conditions, we must adopt concentrated high-level dry education, greenhouses covered with three membranes, greenhouses and other integrated technical measures to increase temperature, prevent low-temperature chilling damage, nurture strong. Do a good job of temperature management in the shed, in the root growth period, the temperature is controlled below 32 °C, the most suitable between 25-28 °C. During the first leaf growth period, the temperature is controlled below 28°C, and most suitable between 22-25°C. During the weaning period (2-3 leaf stage), the temperature is controlled below 25°C, and the optimum temperature is 22-24°C for 2 leaf stage and 20-22°C for 3 leaf stage. When seedlings are 2.5 leaves, the temperature of the shed cannot exceed 25°C for two days. To do well in seedbed water management, it is necessary to highlight "drought" and not "water shortages" to ensure the cultivation of robust seedlings. In the early morning and late, if there is no water spouting at the tip of the leaf, curling of the leaves at the new exhibition at noon, and whitening of the surface of the bed soil, replenish water immediately.
(b) Prevention and control of disease at the seedling stage, with emphasis on preventing blight and blight. Strengthen the prevention and control of disease at seedling stage, use dithiocyano methane, ciprofloxacin, mithican, etc. for soaking and disinfecting, to prevent bastard disease; spray in nutrient soil, disinfect seed dressing, 1 leaf 1 heart The metalaxyl (or metalaxyl manganese zinc) agents are used alone or simultaneously in the three stages of spraying to prevent blight. In addition, rigorous breeding of greenhouse fertilizer and water temperature and humidity management, timely ventilation and hardening seedlings, is also an important measure to prevent pests and diseases at the seedling stage.
In addition, do a good job of field preparation and ensure timely transplanting. After harvesting last fall, the moisture content of rice straw was high. Most of the farmers did not clean up in time and stayed in Daejeon, which caused difficulties in site preparation this spring. To do this, we must rush to complete the field in time. Focusing on the smooth formation of Geda, we will ensure ground level as a mirror and muddy water through land clearing, timely dryness, early soaking, paddle leveling, and adequate subsidence to ensure high standards during the high-yield period. High-quality, high-speed rice transplanting is completed, laying a good foundation for this year's rice production.
