1. Colonization

Generally, before planting, it is necessary to set a point to straighten the seedlings to dry, so that the roots are evenly distributed and stretched, and filled with new fine soil without fertilizer, and compacted, pour enough root water to keep the soil moist.

Two, sapling management

1. Fertilizer and water management

Apply shoot-promoting fertilizer 7-10 days before each batch of shoots, mainly quick-acting nitrogen fertilizer, and apply strong shoot fertilizer when new shoots are self-cutting, mainly compound fertilizer. In the process of plant growth, compound fertilizer, urea, and decomposed organic fertilizer are respectively applied. Generally, fertilization is mainly spread around the tree tray, so as not to burn the roots.

2. Water management

In the rainy seasons of spring and summer, it is necessary to promptly remove stagnant water, and in case of drought in autumn and winter, timely irrigation, cover and moisturize. Pay attention to water control after the autumn shoots mature to inhibit winter shoots germination and promote flower bud differentiation.

3. Put the tip

After planting and before fruiting, the shoots are placed four times a year. When the new shoots grow to 5-6cm, the excessive weak shoots are removed in time, which will help increase the yield.

4. Anti-budget

In order to inhibit the differentiation of flower buds, prevent the formation of flower buds in the following year, reduce nutrient consumption, and promote the rapid formation of the crown. Need to spray agent 920.

3. Results tree management

1. Fertilization

Generally 10 to 15 days before the spring shoots sprout, that is, early to mid-February. Fertilization amount: mainly available nitrogen fertilizers, combined with phosphorus and potassium fertilizers, fertilization amounts to 30% of the year. If the tree is weak and has a large blooming volume, apply proper amount of stable fruit fertilizer, and use nitrogen fertilizer, phosphorus and potassium fertilizer in time 7-10 days before putting autumn shoots.

2. Water management

If it is rainy in summer, it is necessary to promptly remove stagnant water, and moderate water control in autumn and winter to facilitate flower bud differentiation. Drought (irrigate) water in time when it affects tree growth.

3. Prevent diseases

Because oranges are weak against Huanglong disease, they are particularly prone to infection and occurrence. It is the enemy of the growth of Shatangju. Main symptoms: In addition to the appearance of yellow shoots, the main features for identifying the disease are:

The base and edges of the leaves are yellowed, and irregular yellow-green mottled leaves appear. If there is a disease, you need to spray with imidacloprid to eliminate the source of the disease.
