How to raise potted cherries?

Big cherry is also known as Yingqing fruit, cherry bead, cherry and so on. Potted cherry is a miniaturized big cherry orchard. You can enjoy the beautiful scenery full of flowers and fruitful fruits. With the improvement of potted technology in recent years, potted cherries are gradually stepping into the balcony and courtyard of thousands of families. Let's take a look at how potted cherries are raised.

Growth habits of Big Cherry

Big cherry is a fruit tree that likes light, temperature, humidity and fertilizer. It is suitable for growing in the climate with an average annual temperature of 10-12 ℃, annual precipitation of 600-700 mm and annual sunshine hours of more than 2600-2800 hours. The daily average temperature higher than 10 ℃ is 150 to 200 days, and the extreme lowest temperature in winter is not lower than-20 ℃ can grow well and bear normal fruit.

Pot cultivation of Big Cherry

1. Container selection: big cherry cultivation container has good air permeability and no toxic effect on root system, the effect of burning pot and barrel is the best, purple sand basin and plastic basin is the second, and enamel is the worst, because big cherry is not easy to survive after potting.

2. Preparation of basin soil: the root system of cherry has strong respiration and high oxygen consumption. The soil requires high permeability, and the sandy loam soil with loose soil and deep soil layer is the best. The proportion of nutrient soil is turf soil: ring fertilizer: sand = 5:3:2.

3. Seedling selection: big cherry seedlings should choose tree species with strong growth, full branches and buds, well-developed roots and no diseases and insect pests. Perennial young trees require short stems, reasonable distribution of branches and large cutting between branches.

4. potting time: the pot time of big cherries is mostly in early spring. Before potting, the damaged roots and branches are pruned to expose new stubble and the parts with diseases and insect pests are cut off. Secondly, check the drainage hole of the container to keep the drainage of the container smooth.

5, pot method: put a tile upside down on the drainage hole, then spread a layer of about 20 cm of ash, load the nutritious soil, and finally put the saplings, after 2 or 3 times to lift the seedlings, press the soil, and finally the soil surface is about 5 cm away from the edge of the container.

Cultivation and Management of Big Cherry

1. Fertilizer and water management: big cherries should be watered frequently when there are many branches and leaves and high temperature, otherwise the dry soil will affect its growth, blossom and fruit. Fertilization should grasp the principle of frequent application of thin fertilizer, and it is generally required to apply rotten rapeseed cake fertilizer and water every 10 to 15 days from spring to autumn. In autumn, the foliar surface should be sprayed with 0.5% potassium dihydrogen phosphate solution for 2 to 3 times to promote plant growth and flower bud differentiation.

2, heat preservation and moisturizing: big cherries are more cold-resistant, and plastic film can be used to protect against cold in alpine areas. the temperature during fruit setting period should be kept at about 25 ℃, and the humidity during growing period should be kept at 50% to 60%, which is beneficial to flower bud differentiation and increase yield. If there is local frost damage, potted cherries must do a good job of heat preservation and moisturizing measures.

3. Flower and fruit management: flower and fruit thinning of big cherry is the focus of flower and fruit management, bud thinning is better than flower thinning, flower thinning is better than fruit thinning. There are a large number of flower buds in the tree, and some flower buds are sparse during the budding period. The method of operation is to remove the flower buds on the flower cluster bearing branches, pollinate the varieties at the flowering stage, and remove the abnormal fruit when the fruit grows to the size of soybean grains.

4. Shaping and pruning: the central buds of big cherry terminal buds and flower cluster fruiting branches are leaf buds. Flower buds are pure flower buds, mainly axillary flower buds and flower clusters. Axillary flower buds are generally planted at the base of one-year-old branches, and pay attention to the position of flower buds when pruning. Pruning is mainly in summer and auxiliary in winter.

① winter pruning: winter pruning is mainly to adjust the tree type and balance the tree potential. It mainly removes the growing competitive branches, upper dorsal branches, strong branches and slender branches. The elongated branch is truncated, resulting in the retraction of the branch.

② summer pruning: the purpose of summer pruning is to maintain the tree shape, promote flowers and protect fruit. Cut off the competitive branch and the upper branch on the back. Pick the heart when the branch grows to 15cm to 20cm. It is usually completed before July, no more than twice a year. In September or so, when the branch first reaches the top, flatten the branch.
