Planting methods of potted cherries

Cherry is a kind of fruit favored by consumers, which is not only rich in nutrition, but also can regulate qi, strengthen spleen and stomach, and dispel rheumatism. With the popularity of pot technology, some people began to plant potted cherries. So, how to grow potted cherries? What are the planting methods of potted cherries? Let's learn about it together.

First, how to grow potted cherries?

Sowing generally takes place between the end of March and the middle of April (between 20-25 ℃ and different temperatures in the south and north). First soak the cherry kernels in warm water (about 50 ℃) for 12 hours, then rinse once with clean water, mix with plant ash and pour through the water. After the water is completely seeped, cover the soil with 1.5cm-2.0cm fine sand, and gently step on the soil, if the soil moisture (refers to soil moisture content) is different. Need to water the place where cherries need to be planted about 7 days in advance, so that you will not be afraid of "dry buds" after sowing.

After the seedlings are exposed to the soil surface, they should be watered according to the soil moisture. After one month, they can gradually apply fertilizer, apply as little as possible, and give priority to nitrogen fertilizer. Of course, it is best to apply some mature organic fertilizer around in summer.

1. The cultivation of cherry in pot

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

② basin soil preparation: Cherry root respiration is exuberant, oxygen consumption is high. 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: cherry seedlings should choose tree species with strong growth, full branches and buds, well-developed roots and no diseases and insect pests. Perennial saplings require low stem, reasonable branch distribution and high cutting degree between branches.

④ potting time: cherry potting time is mostly in early spring. Before potting, prune the damaged roots and branches to expose new stubble and cut off the parts with diseases and insect pests. 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 ash of about 20cm, 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 and the edge of the container are about 5 cm apart.

2. Cultivation and management of cherry.

① water management: cherries should be watered frequently when there are many branches and leaves and high temperature, otherwise the dry soil will affect its growth and blossom and bear 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: 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: cherry flower and fruit thinning 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 pruning: the central buds of 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.

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.

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.
