When does the orange tree blossom

Orange trees generally bloom from April to May and bear fruit from October to December. During the growth period, orange trees need to be given sufficient light, water and fertilizer to enable them to grow normally. During the maintenance period, an appropriate amount of watering and fertilization should be applied, and orange trees should be sprayed regularly to prevent diseases and insect pests.

How to cultivate orange trees?

1. Seedling planting: when the orange seedlings are planted, the roots of the seedlings are trimmed moderately and placed in the center of the planting hole to stretch the roots, straighten the roots, and gently lift the seedlings upward while filling the soil. Pour enough water on the roots, make a 1-meter plate around the seedlings and cover them with bran shells. After planting orange seedlings, we should do a good job of deep hole expansion and ripening soil, forbid planting tall plants such as corn and wheat in the garden, and do a good job of rational intercropping and weeding in orchards.

2. Fertilizer and water management: orange trees should fully meet the needs of blood orange for various nutrient elements, advocate the application of more organic fertilizer, rational application of inorganic fertilizer and formula fertilizer, and guide fertilization according to the results of leaf analysis, orchard soil analysis and blood orange phenology. Soil fertilization is the main method, combined with foliar fertilization. The methods of ring ditch application, furrow application, hole application and soil surface fertilizer application were adopted. The soil is irrigated when it is dry and drained when it is stagnant.

3. Rational fertilization: orange trees should be applied frequently and thinly, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and fertilized 5-6 times in spring, summer and autumn shoot emergence period. Adult trees apply four times of fertilizer, that is, sprouting fertilizer, fruit protection fertilizer, strong fruit fertilizer, fruit picking fertilizer, sprouting fertilizer 2kg chemical fertilizer, one load of manure water, 1kg fruit protection fertilizer, 1kg phosphate and potassium fertilizer, 1kg fruit fertilizer, 2jin phosphate and potassium fertilizer, 50kg 100kg organic fertilizer and 2jin chemical fertilizer.

4. Pruning techniques: after the elongated branches in the center and the main branches and secondary branches were selected in the young tree stage, they were cut moderately or severely, and the growth balance among the main branches was adjusted by the degree of truncation and the direction of cutting buds. In the result period, we continue to select short-cut treatment of all levels of backbone extension branches, erase summer shoots and promote strong autumn shoots. Measures such as ring cutting, root cutting and water control are adopted to promote flowers for prosperous trees in autumn.
