When watering potted citrus reticulata, attention should be paid to controlling the amount of watering. Usually, we should water the orange trees once a day in summer. If the soil is too dry, we can add more water. In spring and autumn, water can be poured every 2 or 3 days; In winter, you can water every 4 or 5 days, and pay attention to the amount of water to ensure that the soil is moist.

Second, fertilization.

Orange trees like fertilizer, so we should pay attention to applying more thin fertilizer in normal maintenance. We should apply decomposed liquid fertilizer once before plants germinate, and then apply liquid fertilizer every 7 ~ 10 days to promote them to grow more branches and leaves. Fertilization should also be done in time after coring, and some cake fertilizer should be applied during the growth period to cooperate with watering.

Extended data

The growth, development, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil, wind, altitude, topography and slope direction, among which temperature is the most important factor. Even if the temperature difference is 0.5℃, sometimes there will be completely different results. The growth and development of citrus fruits need a temperature of 65438 02.5 ~ 37℃.

The day and night temperatures of flower bud differentiation in autumn are about 20℃ and 65438 00℃, respectively, and the soil temperature of root growth is roughly the same as the ground temperature. If the temperature is too low, oranges will freeze. When the sweet orange is at -4℃ and the satsuma orange is at -5℃, the branches and leaves will be frozen. When the sweet orange is below -5℃ and the satsuma orange is below -6℃, the branches will be frostbitten. When the sweet orange is below -6.5℃, the satsuma mandarin will freeze to death.

Slightly resistant to shade, like warm and humid climate, not cold-resistant, freezing injury occurs when the temperature is lower than -8℃, and it is suitable for growing in deep and fertile neutral to slightly acidic sandy loam.

High temperature is also not conducive to the growth and development of citrus. When the air temperature and soil temperature are higher than 37℃, fruits and roots stop growing. Temperature also has obvious influence on fruit quality: in a certain temperature range, with the increase of temperature, the sugar content and soluble solids increase, the acid content decreases and the quality becomes better.
