Key points of management of citrus in spring

With the warming of temperature in spring, the introduction of citrus dormancy period is the period of citrus sprouting, sap flow, flowering and fruit setting, and it is also a key period in the one-year management of orchards. So how to manage oranges in spring? Let's take a look at the detailed introduction.

1. Dig deep into the soil

Spring is the period of root germination, so it is necessary to do a comprehensive ploughing before this, in order to remove weeds, reduce the sources of diseases and insect pests, improve soil structure, make soil loose and breathable, promote new root germination, and improve root vitality. However, we should also pay attention to the depth when ploughing, shallow ploughing for young trees, so as not to hurt the roots, covering the soil in time after ploughing, and covering properly at low temperature to avoid frostbite of the roots.

2. Apply enough fertilizer

Spring citrus shoot germination, flowering and fruit setting all need more reasons, so the municipal government has achieved the goal of promoting roots and buds. Generally speaking, the fertilizer of promoting bud and promoting shoot should be applied 1-2 weeks before sprouting in spring, but after citrus fruit harvest, the nutrition of the tree is consumed massively, and the new root growth of more fruit trees is often later than that of spring shoot, so the absorption of fertilizer and water is less, and foliar fertilizer should be sprayed at the same time. For young trees mainly foliar spraying, supplemented by ground fertilization, ground fertilization should pay attention to the concentration, do not spread, mainly nitrogen fertilizer, with phosphorus and potassium fertilizer. The flowering of adult trees needs a lot of nutrition, so nitrogen fertilizer is the main fertilizer before sprouting, with phosphorus and potassium fertilizer, foliar fertilizer is used to supplement potassium fertilizer at flowering stage, and appropriate amount of boron fertilizer is maintained.

3. Water management

Citrus should be watered in time when they encounter drought before and after sprouting and flowering, so as not to affect the sprouting and flowering, while spring is sometimes a rainy economy, so the drainage of orchards is more important, once the drainage is poor, it can easily lead to plant root rot. In addition, if the root system stagnant water, it will also cause yellowing, withered branches, falling flowers, fruit and other phenomena, serious will lead to the death of the tree. Therefore, in spring, we should pay attention to stagnant water, loosen the soil and increase soil permeability to facilitate root growth.

4. Shaping and pruning

Spring pruning is beneficial to optimize tree structure, adjust light, balance tree potential and increase yield. generally, young trees are mainly light pruning for the purpose of cultivating tree shape and expanding tree crown, mainly to fix trunk and cultivate main branches. the short height of the fixed trunk should be 30 cm of painkiller. Before sprouting, the mature autumn and winter shoots were topped or cut short, and the dense branches were thinned properly to expand the crown. The number of results should be in accordance with the principle of ventilation and light transmission and reasonable load, mainly pruning fruit stem branches, dry and withered branches, dense branches, cross branches, disease and insect branches, retracted or short truncated fruit branches and so on.
