How to irrigate eggplant? Latest irrigation techniques and methods tutorial
Eggplant is a vegetable planted in spring and harvested continuously through summer. In production, eggplant needs both sufficient water and shares a common characteristic of the Solanaceae family: its fibrous roots fear flooding and waterlogging. Therefore, in the field management process of growing eggplant, water management is especially important and requires careful, targeted irrigation to avoid damage caused by insufficient or excessive water.
I. Water requirements
The root system has no main root or an inconspicuous main root, and the fibrous roots penetrate to a depth of about 10 cm, so when watering, water should be applied close to the root system. Also, water thoroughly and completely to ensure all roots absorb water evenly. However, precisely because the roots are weak, it is best not to use flood irrigation, nor to spray directly with a hose, as this can easily cause soil erosion and expose the roots. Eggplant has large leaves and needs sufficient water in the early stage to maintain leaf growth; in the later stage, mainly the fruit needs water, and the requirement is not high, so watering should be reduced.
II. Irrigation methods
1. Sowing period
When planting eggplant, be sure to water enough basal water; the planting area can be thoroughly watered once. At least let the water remain in the permeable layer to keep the deeper soil moist for a long time. The surface can be a bit dry to prevent excessive humidity from frequent watering that promotes seedling-stage diseases.
2. Seedling recovery period
Generally no watering. After the seedlings are transplanted, let them adapt to the environment and encourage the roots to absorb water and nutrients on their own, laying a foundation for later growth. However, if the soil's water-holding capacity is too poor, a small amount of water can be applied appropriately so the seedlings do not lose water; it would be bad if seedling recovery fails and they instead wither and die.
3. Seedling stage
One week after transplanting, the seedlings should have recovered and resumed normal growth. At this time, water once to ensure leaf expansion for photosynthesis and to produce some of the nutrients needed for their own growth. This watering can be combined with soil cultivation and watering to ensure water absorption and also benefit root growth. After that, no watering is needed until the first fruiting, except of course in drought weather.
4. Fruiting period
Once fruiting begins, water more and increase the frequency of watering. Generally, sufficient watering at this time makes the eggplants large and good in color, with more water and tender flesh, avoiding aging and becoming cottony. It is generally best to water thoroughly once rather than little by little many times, which cannot meet the needs of fruiting. Water thoroughly about once a week, continuing until fruiting stops.
III. Precautions
During heavy rain or consecutive rainy days, accumulated water should be drained away promptly. If it is too wet, some plant ash can be scattered to absorb moisture, preventing pests and diseases caused by excessive humidity and root rot that causes plant death.
When growing eggplant in open fields, the above is the content on water control. Irrigation and some other measures are our best methods for water control in cultivation. For eggplant, which needs water but fears it, irrigation needs to be decided based on factors such as the environment and growth stage.
