Eggplant generally needs less water in the early stage of growth, so it is best to control the water properly when watering for the first time, and the water will gradually increase in the future, so as not to harm its root system and affect its normal growth.
In addition, it is best to combine topdressing when watering. More water is needed in the middle and late growth period, and a large amount of water demand needs to be met, and the water holding capacity should be kept above 70%.
Time and frequency of watering eggplant
Eggplants are usually watered after 4 pm, once every 3-4 days after planting and once every 7- 10 days at seedling stage. Don't water eggplant on rainy days, so as to avoid waterlogging, affecting root growth and infecting virus.
Eggplant watering in spring
The temperature is unstable in early spring. If it rains for several days, don't water it, it's easy to get waterlogged.
Water eggplant in summer.
In summer, the temperature is high and the sunshine is strong, so it will evaporate quickly after watering, so water it in time to avoid burning plants.
Water eggplant in autumn.
The temperature is low in autumn, so water it properly. According to the actual situation, keep the soil moist.
Watering eggplant in winter
In winter, it is best to water the eggplant in greenhouse on sunny days, but not on cloudy days. The water temperature is relatively high in sunny days, and the temperature will not drop significantly after watering.
Eggplant watering method
1. When planting eggplant, you need to pour enough "root water". When it takes root, you just need to keep the soil moist. Before flowering, water should be strictly controlled. When the fruit just begins to develop, it should be watered with "fruit stabilizing water" in time to ensure the growth of young fruits.
2. When the eggplant fruit grows fastest, it needs water most, so it needs to be watered again to promote the rapid expansion of the fruit.
3, 2-3 days before harvesting, you should also lightly water "skin washing water" to ensure that the fruit is fresh and tender while fully growing, and then water it in time in the early and middle stages of fruit development and a few days before harvesting to ensure the growth and development of the fruit.
4. Too much watering is easy to cause water accumulation, which is not good for eggplant growth, and there will be problems of retting roots, so drainage should be done in time.
