Sweet orange trees are suitable for growing in loose and fertile soil with good drainage and ventilation. When planting, humus soil, garden soil and some base fertilizers can be used for soil preparation. This kind of soil has high fertility and is very suitable for the growth of sweet orange trees.
2. Lighting equipment
Sweet orange tree is a sunny plant, which needs plenty of light. It can be planted on the balcony or in a place with good ventilation and light transmission outside. In summer, when the light is strong, it is necessary to shade properly so as not to affect the normal growth of sweet orange trees.
3. Temperature
Sweet orange trees are suitable for growing in warm places. The optimum growth temperature of sweet orange trees in a year is 23-29℃, and the minimum growth temperature is 12.5℃. When it is hot in summer, it is necessary to shade and cool down, otherwise the fruit will stop growing. Cold tolerance is also poor. When the temperature is below -7℃, the whole plant will freeze to death, and warm-keeping measures must be taken in winter to ensure safe winter.
water
Sweet orange trees like humid climate and are not tolerant of drought. Severe drought will stop the growth of fruits. Generally, it is watered immediately after drying, so it must be watered thoroughly to keep the soil moist all the time, but no water can accumulate in the soil, otherwise it will cause leaves and fruits to fall off and even lead to root rot and death.
5, fertilization
Sweet orange trees need more nutrients in the growing period, so they need to apply some fertilizers to supplement the nutrients in the soil. General fertilization is mainly based on soil fertilization, combined with foliar fertilization. It is more beneficial to the growth of sweet orange trees to apply thin chemical fertilizer with nitrogen fertilizer as the main fertilizer and a certain amount of phosphorus and potassium fertilizer in Qin Ying. Generally, it can be fertilized 5-6 times in spring, summer and autumn. Adult trees can be fertilized four times.
