Culture methods and matters needing attention of four seasons fruit

Four seasons fruit is suitable to be planted in loose, fertile and slightly acidic soil with good drainage, the suitable temperature for growth is 10-25℃, the pot soil needs to be kept moist during the growth period, the watering amount needs to be controlled at the flowering stage, and the watering amount should be gradually increased at the fruiting stage, phosphorus fertilizer, potassium fertilizer and decomposed fertilizer can be applied according to different growth stages, and the plants can be reshaped at the later stage, and dead branches, light branches, disease and insect branches can be pruned, and pest control measures should be taken.

1. The cultivation method of four seasons fruit

1. Select soil

Four seasons fruit is not resistant to cold, like warm and humid, sunny environment, can be planted in loose fertile, good drainage slightly acidic soil.

2. Suitable temperature

The suitable temperature for fruit growth is 10-25℃, and the temperature should not be lower than 2℃ in winter. It can be moved indoors before frost to avoid fruit drop due to freezing injury.

3. Reasonable watering

During the cultivation period, it is necessary to keep the pot soil moist. In the flowering stage of the four seasons fruit, it is necessary to properly control the watering amount. If the pot soil is too moist, it will be easy to drop flowers. When the small fruit is full of branches, gradually increase the watering amount. In the midsummer stage, it is necessary to keep sufficient water, and then 3-4 days before wintering, move to the south-facing window with sufficient sunshine for cultivation.

4. Regular fertilization

During the growth process of the four-season fruit, decomposed thin fertilizer can be applied once every 7-10 days. From the stage of bud pregnancy to young fruit, 2-3 times of rapid phosphorus fertilizer can be added to promote the growth and development of the fruit. After flowering, more phosphorus and potassium fertilizer should be applied to promote the fruit setting time to be longer. When potted four-season fruit, it is necessary to timely pick the core, which is conducive to promoting more flowers and more fruits.

5, plastic (natural happy shape)

The plant trunk height is 20-40cm, the main branches (3-4 branches) are evenly distributed on the trunk, the branch angle of the main stem is 30°-50°, and 2-3 auxiliary main branches are reserved on each main branch. Usually, after the formation of the third main branch, the central trunk is cut off and twisted to one side as the fruiting branch group.

6, pruning

(1) Young trees: light pruning can be carried out. After selecting the main branches, auxiliary main branches and extended branches in the center, moderate or heavy truncation shall be carried out, and the balance point of growth among the main branches shall be adjusted according to the degree of truncation and the direction of bud shearing. The over-dense branches shall be properly pruned, and the branches with weak growth in the middle and lower parts of the crown shall be reserved.

(2) Early fruiting period: The extended branches of all levels of backbone can be cut short, and then the summer shoots can be removed to promote the growth of autumn shoots. When entering autumn, it is necessary to take measures to promote flowering such as root cutting, ring cutting and water control for prosperous trees.

(3) Full fruiting stage: can retract flower drop fruiting branch group, decline branch group, prune dead branches, pest branches, light blocking branches.

II. Pay attention to pest control

1, when aphids occur, can use smoked cigarette butts soaked in water, evenly sprayed in the occurrence of insect pests, can also use trichlorfon and other pesticides to control aphids.

2, when the occurrence of red spiders, can spray a small amount of soapy water and garlic juice synthesis of liquid, spray it on the insect body, has a higher inhibitory effect.
