How to grow tangerines? When will it blossom? How many times a year does the fruit grow?

The four seasons tangerine is an evergreen shrub or small tree of Rutaceae and citrus. Tree erect, branches and leaves dense, much branched, spiny or unarmed, dark green leaves, wavy obtuse teeth, narrow wing leaves. So how to grow tangerines? When will it blossom? How many times a year does the fruit grow?

The production and planting methods of four seasons tangerine bonsai are as follows:

First, Miaoyuan

Grafting is often used to obtain seedlings. Most of the rootstocks are trifoliate orange and Chinese wolfrafter, and the seedlings can also be obtained by cutting.

Second, modeling

1. Potting usually begins after the Qingming Festival. The matching basin can be made of plain burning basin or purple sand basin, and the basin soil can be mixed with humus soil, garden soil and cinder. Rotten cake fertilizer and human feces and urine can be used as base fertilizer.

2. Do the following two points when modeling:

First, understand the physiological characteristics of tangerine. Tangerines can blossom and bear fruit many times in a year. The flower bud differentiation can be carried out on the basis of certain nutrition after the shoot stops growing. The branches that germinated in the same year can blossom and bear fruit.

Second, plastic surgery and pruning. Before the spring shoot sprouting every year, the tangerine was cut again. The withered branches, weak branches, disease and insect branches and over-dense branches were cut off, and the strong branches were retained with 2 mi 3 buds in each branch. Weak trees can be cut to the first branch to promote strong spring shoots. When the spring shoot grows to 15 cents and 20 centimeters long, it is necessary to carry out coring treatment and apply phosphorus and potassium fertilizer at the same time to form a neat crown, so that the crown is plump and the tree body is healthy.

III. Maintenance and management

1. Watering. Tangerines like to be warm and humid, but avoid stagnant water. During the growing period, it is better to keep the soil moist. Spray water twice a day in summer, and spray water to the ground to cool down and increase air humidity. Avoid accumulating dust on the leaves, so wash the leaves frequently. During the period of flower bud differentiation, the water of the tree should be controlled in order to promote flower bud differentiation. Tangerines grow vigorously and need to be controlled for a long time. In order to avoid the defoliation caused by excessive drought, the tangerines can be watered for 3 days and watered for 2 days. It can also be watered for 7 days after a drought. After the tree is slightly restored, it is treated with ring cutting to promote the flowers.

2. Farm manure is the main fertilizer. Spray 2% borax and 5% urea at flowering stage. Applying phosphorus and potassium fertilizer after fruit, and spraying gibberellin of 50ppm one month before fruit drop, in order to increase fruit setting rate and prolong ornamental period.

3. It is appropriate to change the basin once a year. Each time you change the basin, the root should be treated and the old soil of 1 stroke 3 should be removed.

4. Thinning flowers and fruits according to the principle of weak, strong and uniform distribution, thinning the flowers and fruits that are too dense.

5. Pest control should pay attention to effective control of diseases and insect pests such as shell insects, red spiders, aphids and powdery mildew.
