Cultivation and Management techniques of navel Orange

The most attractive thing about navel orange is its orange appearance, which looks very attractive. Eating navel oranges often can not only fight aging, but also prolong life. Now there are many kinds of navel oranges on the market, and the taste is also different. Next, let's learn how to grow navel oranges that feel good and are liked by consumers.

Cultivation and Management techniques of navel Orange

1. Build a garden. Navel oranges are suitable for ≥ 10 °annual accumulated temperature of 4500 ℃ ~ 6500 ℃, average annual temperature of 15 ℃ ~ 19 ℃, minimum temperature of minus 6.5 ℃, maximum temperature of 38 ℃, annual rainfall of more than 1000 mm, and air relative humidity of 65% and 72%. The mountain garden is better with a slope of less than 15 °, and horizontal terraces must be built with a large slope, with a south, southeast or southwest slope, with deep and fertile soil, adequate water sources and convenient transportation.

2. Changing the paddy field to the orchard requires convenient drainage and irrigation, and the plough bottom should be broken when the orchard is built. The site of the park should be far away from cities and towns, and there are no factories, mines, hospitals and garbage dumps around it. The contents of heavy metals and harmful substances in all kinds of soil should meet the requirements of pollution-free cultivation. In addition, it is necessary to plan the main roads, branch roads and farming roads according to the size of the orchard, build water conservancy sprinkler irrigation facilities, retain them in the orchard or build taller trees as shelterbelts.

3. When the garden is built, the depth of the whole garden is 20 cm, dig a planting pit or trench of 1 meter square according to the row spacing of 2 meters × 3 meters, and first apply the crude organic fertilizer. Add an appropriate amount of calcium magnesium phosphate fertilizer and lime to fill the bottom of the hole, then use 50 kg of pig and cow manure per cubic meter to mix the flat pit, and finally use 1 kg rotten stable fertilizer plus 0.5 kg compound fertilizer, mixed with fine soil barrier to cultivate a square planting pile 20 cm higher than the soil surface.

4. When planting, the root system of the seedling is arranged evenly and stretched in layers, and then the filling soil is compacted and poured with enough fixed root water, and the planting depth should be 2cm and 3cm above the ground after the soil is settled.

Water Management of navel Orange planting

Rational irrigation is also an important measure for high yield of Newhall navel orange. In general, the relative water holding capacity of citrus orchard soil should be kept between 65% and 75%, that is, to keep the soil relatively moist. Rain Water more seasons in spring and summer, to do a good job of terrace drainage ditch cleaning work to ensure that the citrus garden does not have stagnant water. Rain Water is less in autumn, especially from October to November, so it is necessary to strengthen irrigation to facilitate fruit expansion. In addition, we should pay attention to prevent prolonged drought and rain, resulting in fruit cracking.

The method of fertilizing navel orange with soil

1. Strip ditch application. At the outer edge of the crown dripping line, strip fertilization ditches are opened on the opposite sides, and the fertilizer and soil are mixed and applied into the ditch, and the position is changed each time.

2. Ring ditch application. Open a ring fertilization ditch along the outer edge of the crown dripping line opposite to both sides, mix fertilizer and soil into the ditch, and change the position each time.

3. Radial ditch application. Start at a certain distance from the trunk within the projection range of the crown, dig out 4-6 deep and radial fertilizer ditches, mix fertilizer and soil evenly into the hole, and change the position each time.

4. Hole fertilization. Dig several fertilizer holes within the projection range of the crown, apply fertilizer and soil evenly in the hole, and change the position each time.

Main methods and effects of pruning navel oranges

1. Cut short. The method of pruning a section of a new shoot or perennial branch. Usually, the truncation of the new shoots of the same year can promote the branches, reduce the branch height and enhance the tree potential; the truncation of perennial branches can reduce the branch order of the shoot and make the new shoots more prosperous.

2. Thinning. Cut off new shoots, perennial branches, or groups of branches from their basal branches. Thinning and pruning can reduce the total branch of the tree, help to ease the growth potential, and promote flowering and fruiting.

3. Retract. Cut off the weak part of the front end of a large branch group, and then cut the strong branch moderately short. Through the retraction treatment, the vegetative growth of the cut branch was promoted, and the branch group which had tended to decline was renewed into a new branch group with strong growth potential.

4. Wiping buds and putting shoots. When navel orange buds germinate sporadically, erase them for 2 or 3 times in a row, wait for more buds to mature, and then let them produce a large number of new shoots neatly and uniformly.

5. Pick the heart. The tip of the new shoot that has not stopped growing is removed during the growing season. It's actually a very mild cut during the growing season.

6. Support, pull and hang branches. By applying external force, the growth direction or angle of new shoots and big branches can be changed to adjust the growth potential and distribution space.

The cultivation of navel oranges originally requires so many procedures, and every step is very important. If you want to grow delicious navel oranges, you must be patient enough to do a good job of every step. I hope the editor's method is useful to everyone and can grow navel oranges with high yield and delicious taste.
