Garden construction and land selection: select the slightly acidic sandy land with perfect leeward and sunny drainage system to build the garden, and select seedlings for sowing: select seedlings with strong branches and sow them in February or September every year. Water and fertilizer management: timely irrigation in drought, timely drainage in rainy season, and topdressing spring fertilizer in February-March every year. Maintenance method: regular shaping and pruning when planting.

Planting method, garden establishment and land selection of navel orange 1

Navel orange is suitable for planting in mountainous areas with convenient irrigation and drainage and convenient transportation. It is best to choose a slightly acidic sand civil garden with perfect drainage system in the leeward and sunny direction, and at the same time, it is best to keep the annual average temperature between 18-22 degrees, and the minimum temperature is not lower than 5 degrees. The temperature is too low, the growth rate is slow, and it is vulnerable to freezing injury.

2. Select seedlings and sow.

Before planting navel orange, the branches were thick and healthy, the leaves were shiny, the root system was complete and there were few broken roots, and almost no grafting traces were seen. The best seedling height is 70- 100 cm, and the best sowing time is from February to September every year. At this time, the survival rate of planting will be greatly improved if the temperature is suitable and there is more precipitation.

3. Water and fertilizer management

Navel orange needs a lot of water and fertilizer in its growing period, and the requirements for water and fertilizer are different in different growing periods. A large amount of water and fertilizer are needed to provide nutrition during germination, flowering and fruit development, but it is necessary to pay attention to the fact that the roots can't accumulate water, the fruits can't be watered one month before harvesting, and they should be irrigated in time during drought and drained in time during rainy season. Spring fertilizer is topdressing in February-March every year, and compound fertilizer is applied in furrows outside the roots to avoid excessive fertilizer.

4. Maintenance methods

Navel oranges should be pruned in winter, spring, summer and flowering. Pruning too long and too dense branches can improve ventilation and light transmission conditions, which is conducive to flower bud differentiation, pruning diseased branches, dead branches, weak branches and useless long branches to reduce nutrient consumption and keep branches weak.
