Methods for potting small persimmons:

1. Varieties and seedlings: persimmon seedlings that have not been out of the nursery for many years can be used, or perennial persimmon trees that have been eliminated in the courtyard can be used.

2. Pots and pot soil: Choose tile pots to plant commercial seedlings. The tile pots with diameters of 24 cm, 30 cm and above are available. 24 cm pots can be used to plant persimmon seedlings that came out of the nursery that year, and 30 cm pots Perennial persimmon seedlings can be planted in tile pots with a diameter of over 30 cm, and larger persimmon trees can also be planted in small tanks with a cellar of over 20 liters.

The potting soil is mixed with discarded leguminous crop straws and field soil in rural areas. It is piled into granular fertilizer soil in about a year. Use 1/2 compost soil + 1/4 garden soil + 1/4 Mix sand (or cinder) into pot soil. Add 1 kilogram of nitrogen, phosphorus and potassium compound fertilizer to every cubic meter of pot soil and mix well.

3. Potting and repotting: pot the persimmon seedlings during the dormant period, place 1-2 pieces of broken tiles on the bottom hole of the pot, put a layer of coarse sand on the bottom of the pot, and fill in part of the pot soil. Add the persimmon seedlings, then fill the pot with soil, lift the stem of the seedlings, tap the edge of the pot, and compact the pot soil. The pot soil should not be filled too full to block water when watering. Water thoroughly after planting. Repot once every 2-3 years, and choose a larger pot. It should be done during the dormant period. After removing the potted persimmon with soil from the pot, cut off the mesh root pad and remove about 1/4 of the soil from the roots. Then, like the previous pot, put it in the pot, add potting soil, and water it once.

4. Fertilizer and water management: Start fertilizing the persimmons after they sprout. Use fermented organic liquid fertilizer, add 10 times more water, and apply once every 7-10 days. In the early growth stage, 0.3% urea solution can be applied several times. During the fruit expansion period, 0.3% potassium dihydrogen phosphate solution or 0.3% potassium sulfate solution can be applied twice. In addition, 0.3% urea solution can be used for external fertilization about 2 times before July. During the fruit expansion period, 0.2% potassium dihydrogen phosphate solution or 0.3% potassium sulfate solution can be used for external fertilization about 2 times. In spring and autumn, when the weather is fine and the temperature is high, water should be watered once a day. In summer, when the weather is hot, water should be watered once in the morning and evening. In winter, water should be watered even if the pot soil is dry.

5. Plastic pruning:

(1) Plastic surgery. According to the size and purpose of the pot, a tile pot with a diameter of 30 cm is determined. The height of the persimmon trunk is about 30 cm, and the height of the tree is about 80 cm. 5-7 backbone branches are cultivated on the upper part of the trunk, and the branch group and the fruiting mother branch are cultivated on it. , cultivated into a natural semicircle.

(2) Pruning. For saplings planted that year, the backbone branches are strong and strong. Leave about 20 centimeters for topping under conditions of sufficient fertilizer and water to promote the growth of secondary branches. Several buds at the front of the secondary branches can differentiate into mixed buds that year. When pruning the backbone branches, choose short cuts at the full buds and pay attention to the direction of the buds to maintain the balance of the backbone branches at the same layer. When the mother branch is too long, cut off several buds at the front, and the mixed buds at the back can also produce branches. Short fruit-bearing mother branches need not be cut short. Shorten the thin developing branches or fruiting branches to the three buds at the base to encourage them to grow into better fruiting mother branches. During the fruiting period, pay attention to renewal and pruning of potted persimmon fruits. Some strong fruiting mother branches should not be pruned or should be lightly pruned. Weak fruiting line branches or weakly developing branches should be heavily pruned to promote their branching.

6. Key points of pest and disease control:

(1) Persimmon leaf spot. Damage to leaves or persimmon stems. The damage is more severe during thunderstorms. Spraying is generally carried out in June, using 1:5:500 Bordeaux mixture or 500 times liquid of 65% Zinc WP.

(2) Turtle wax scale. The branches are damaged, and in severe cases, the tree will weaken. Eggs are laid and hatched as early as June to July. After mid-June, spray 50% dichlorvos solution or 3000 times dichlorvos solution for prevention and control.

7. Flower and fruit management: If potted persimmon trees are well managed, they can bloom and bear fruit in the second year after planting. Cloud persimmon can parthenocarpy. However, there are several peaks of flower and fruit drop during the growth period. To prevent excessive flower and fruit drop, flower and fruit management should be strengthened.

Place potted persimmons in a place with good ventilation and light transmission to reduce fruit drop. During the flowering and young fruit stages, nitrogen fertilizer is the main fertilizer, and organic liquid fertilizer is mixed with 0.3% urea solution. The pot soil should be kept moist during the flowering and young fruit stages to prevent excessive flower and fruit drop caused by excessive drought. Timely watering is also required during the growth period of the fruit, as soil drought will aggravate fruit drop. Too many fruits on the same branch will be detrimental to fruit growth and flower bud differentiation. Some small fruits and inferior fruits should be thinned out.

8. Overwintering: In winter, place the potted persimmon in a sunny place sheltered from the wind, and cover the pot with some hay. Check the pot soil when it does not rain for a long time or before a cold snap comes. If the pot soil is dry, water it once to make it easier to survive the winter and prevent cold.
