Sand Sugar Orange Planting Technology

1. Colonization

Generally, it is necessary to set a point before planting, straighten the stems of the seedlings, make the root system evenly distributed and stretch, fill it with new fine soil without fertilizer, and compact it, drench the root water to keep the soil moist.

2. Sapling management

1. Fertilizer and water management

7-10 days before the tipping of each batch of shoot tip fertilizer application, mainly with quick-acting nitrogen fertilizer, when the new shoot self-cutting strong shoot fertilizer, mainly compound fertilizer. In the process of plant growth, compound fertilizer, urea, and decomposed organic fertilizer are applied separately. Generally, fertilizer is mainly spread around the tree disk, so that it will not burn roots.

2. Moisture management

In the rainy season of spring and summer, the accumulated water should be eliminated in a timely manner, and in case of drought in autumn and winter, water should be irrigated and covered with moisture in a timely manner. After the autumn shoots are mature, pay attention to water control to inhibit winter shoots germination and promote flower bud differentiation.

3. Flipping

After planting and before hanging the fruit, four shoots are placed each year, and the new shoots grow to 5 to 6 cm, and excessive weak shoots are removed in time, which is conducive to increasing yield.

4. Anti-bud

In order to inhibit the differentiation of flower buds, prevent the formation of flower buds the following year, reduce nutrient consumption, and promote the rapid formation of tree crowns. Spray 920 is required.

3. Results tree management

1. Fertilization

Generally 10 to 15 days before the spring shoots germination, which is the first and middle of February. Fertilizer amount: mainly based on quick-acting nitrogen fertilizer, with phosphorus and potassium fertilizers, the amount of fertilizer application accounts for 30% of the whole year. If the tree is weak and the amount of flowering is large, an appropriate amount of fruit fertilizer should be applied, and it should be nitrogen fertilizer, phosphorus and potassium fertilizer 7 to 10 days before the autumn shoots.

2. Moisture management

If it is rainy in summer, it is necessary to eliminate the accumulated water in time, and moderate water control in autumn and winter to facilitate flower bud differentiation. When the drought affects the growth of the tree, water (irrigate) in time.

3. Prevent diseases

Because oranges are weak against Huanglongbing, they are particularly susceptible to infections. Is the enemy of sand sugar orange growth. Main symptoms: In addition to the appearance of yellow shoots, the main features to identify the disease are:

The base and edges of the leaves are yellowed, and irregular yellow and green mottled leaves appear. If disease occurs, spraying with imidacloprid is needed to eliminate the source of the disease.
