(1) Watering. In general, we need to consider the soil condition, seedling health, and overall environmental factors. First, check the soil. The first thing is that Dihuatong (a type of wheat variety) should not be overwatered during the Qing Shui stage. The second is to assess the moisture level by touch—when the soil feels dry and the plants are seriously lacking water, it's time to water. However, if the situation is not critical, it’s better to delay watering to avoid unnecessary irrigation. This helps maintain good wheat fields without causing water shortages.
B. Check the seedlings. For general wheat, early watering is recommended. For high-yield fields, it's better to delay watering slightly. Follow the order based on the seedling condition: yellow or weak seedlings should be watered early in the Qing period; moderately weak seedlings can be watered at the early Qing stage; late-developing seedlings should be watered during the green mid-stage; strong, healthy seedlings can be watered later. If there is a large amount of fertilizer applied, watering should be done after the jointing stage.
C. Consider the weather and conditions. If the soil has enough moisture, water it in a timely manner. If the soil is dry, you can start watering earlier as needed.
(2) Fertilization. For yellow or weak seedlings, it's important to apply fertilizer early to help them recover and promote growth during the green-up phase. For strong and healthy wheat fields, it's acceptable to delay fertilization appropriately. This ensures that nutrients are used efficiently and the plants receive what they need at the right time.
Overall, proper watering and fertilization are crucial for healthy crop development. It's essential to observe the field regularly and adjust your practices according to the specific needs of the plants and environmental conditions. By doing so, you can maximize yield and ensure sustainable farming.
